The embodiment of the present invention is primarily upon following technical problem: firstly, current block chain node can not handle search The hypertext transfer protocol requests that engine is sent；Secondly, current network search engines are grabbed by web crawler The mode of webpage carrys out the information in traverses network, but current search engine can not traverse the block in block chain network Chain data；Again, when being retrieved to the data in existing block chain, due to the data volume in block chain be easy to cause greatly it is negative The block chain node burden of duty retrieval is very heavy, retrieval rate is slow, recall precision is low and may interfere with the normal operation of block chain, Additionally there may be the risks for obtaining protected data (that is, private data).In addition, current search engine is searched for All should be public data, and block chain network may store public data and private data simultaneously, in search process These two types of data should be distinguished.

To solve these problems, the search service for being directed to block chain network is realized, the embodiment of the present invention provides firstly A kind of hypertext transfer protocol interface, the hypertext transfer protocol interface is for example in the search node of block chain, so that searching Socket point is capable of handling the hypertext transfer protocol requests by search engine or user equipment transmission.Secondly, in search node Setting caching, enables the caching to store the index that search engine or user equipment were retrieved within a predetermined period of time.Again, The embodiment of the present invention using the uniform resource location of other webpages as information by being added in the webpage, so that search Engine can realize the webpage capture function for block chain network by the web page interlinkage to other webpages.In addition, this hair Bright embodiment also directed in block chain network public data and private data carried out differentiation processing.More specifically realize Method and other advantages of the invention see below in elaboration.

Fig. 1 shows the schematic diagram of the network structure 100 of the block chain of content according to the present invention, the block chain in Fig. 1 Network structure 100 includes block chain node 111,112,113,114,115,116 and search node 117；Wherein, search section Point 117 includes caching.Network Synchronization data, the network can be passed through between block chain node 111-116 and search node 117 It can be any wired and or wireless network.

In the content of present invention, search node 117 can only synchronize public data, be unable to synchronous private data.It needs It is noted that can realize that data are synchronous using existing or exploitation in the future simultaneous techniques in the content of present invention.In addition, The caching being arranged in search node 117 can store the one or more indexes retrieved in the set time period, each Index includes uniform resource location, webpage associated with the uniform resource location and the second time retrieved Information.Fig. 2 B shows the exemplary index of storage in the buffer, and which includes URL1 and corresponding webpage html_ 1, the second temporal information STAMP 1, URLn and corresponding webpage html_n, the second temporal information STAMP n.In addition, In view of the limitation of buffer memory capacity in search node 117, at the end of the set period of time, rope all in the caching will be deleted Draw, to realize the real-time update indexed in caching.

Fig. 2A shows the flow chart of the method 200 for searching for block chain data, in the present embodiment, shown in FIG. 1 Method 200 shown in Fig. 2A can be implemented in search node 117 in block chain network 100, specific as follows:

Step 210: via hypertext transfer protocol interface webpage read requests, the webpage read requests include the One uniform resource location and first time information.

In specifically crawl webpage information, search engine end can increase following functions, the i.e. accessible area of search engine Block chain entry address (such as: http://test.com.homepage), in order to which search engine is able to access that the block chain. Alternatively, user can use browser access block chain entry address (such as: http://test.com.homepage), make It obtains user and is able to access that the block chain.

Step 220: determining and whether there is index associated with first uniform resource location in caching.

In this step, being determined according to first uniform resource location in the webpage read requests in caching is It is no to there is index associated with the first uniform resource location, and the buffer memory was retrieved within a predetermined period of time One or more indexes, each index include the uniform resource location retrieved, with the unified resource positioningly The associated webpage in location and the second temporal information

Step 230: in the presence of index associated with first uniform resource location in the caching, and In the case that the first time information is earlier than second temporal information in the index, assisted via the Hyper text transfer It discusses interface and returns to webpage associated with first uniform resource location；Specific embodiment is as follows:

First, judge whether search engine or user once accessed net associated with the first uniform resource location Page showed search engine or user once when there is index associated with the first uniform resource location in the caching Through accessing；Then, judge the concrete modification time (that is, first time information) of the webpage of the access whether earlier than caching The modification time (that is, second temporal information for indicating block chain data renewal time) of the corresponding web page of middle storage, when first When temporal information is earlier than the second temporal information in the index, show that modified mistake first uniform resource location is related The webpage of connection.

Second, it, will be via super text when the determination associated webpage of modified mistake first uniform resource location This transport protocol interface returns to the webpage associated with the first uniform resource location in index to search engine or user, Thus ensure that search engine or user can obtain newest search result.

In addition, specific to how by generating webpage associated with the first uniform resource location, implementation It can be diversified.Such as block chain data pointed by the first uniform resource location can be generated in webpage, In addition, this second there are at least one second i.e. second uniform resource location of uniform resource location Uniform resource location can be also presented on the webpage, so, which can either include the data of block chain, also can Including uniform resource location.With multiple uniform resource locations, these uniform resource locations It can be sequentially arranged on the webpage.It also can be by the way that block chain data be generated and block chain number according to its logical relation The mode of the associated Boolean Search dendrogram of data in is realized.

Next, which is returned into user equipment or search engine.User equipment or search engine are receiving After the webpage of the return, block chain data therein and its access address can either be directly extracted, it also can be to block link network Further webpage read requests are initiated in network side, to grab subsequent block chain data.

If there is index associated with first uniform resource location and described the in the caching In the case that one temporal information is equal to second temporal information in the index, via the hypertext transfer protocol interface Return to the mark for indicating that webpage is unmodified.Specifically, it is determined that existing in caching related to first uniform resource location The index and first time information of connection are equal to the second temporal information in respective index, then show user or search engine once The webpage of search does not change, namely without providing search result to user or search engine, therefore assists via Hyper text transfer It discusses interface and returns to the mark for indicating that webpage is unmodified.In the concrete realization, it is above-mentioned to show that HTTP status code ' 304 ' can be returned Situation.

In the present embodiment, if it is determined that index associated with the first uniform resource location is not present in caching, Then method 200 further includes following steps:

Firstly, the case where index associated with first uniform resource location is not present in the caching Under, obtain the first block chain data at first uniform resource location.Secondly, judging whether there is at least one Second uniform resource location, wherein the second block chain number at least one described second uniform resource location According to associated with the first block chain data.Again, in the feelings that there is at least one second uniform resource location Under condition, generated and first system according to the first block chain data and at least one described second uniform resource location The associated webpage of one resource locator address；Or the case where at least one described second uniform resource location is not present Under, webpage associated with first uniform resource location is generated according to the first block chain data.Then, via The hypertext transfer protocol interface returns to webpage associated with first uniform resource location.Finally, by this One uniform resource location, webpage associated with first uniform resource location and the second temporal information are as new Index be stored in the caching.

In the content of present invention, obtains the first block chain data at first uniform resource location and specifically wrap Include: determined whether according to the account book storage location of the first block chain data obtain first unified resource positioningly The first block chain data at location；It specifically, is open number in the first block chain data or the second block chain data In the case where, the first block chain data or the second block chain data are stored in open account book；And described In the case that first block chain data or the second block chain data are private data, the first block chain data or described Second block chain data are stored in privacy account book；The situation in the open account book is stored in the first block chain data Under, obtain the first block chain data at first uniform resource location.

In the content of present invention, obtaining the first block chain data at first uniform resource location can be with It include: to be determined whether to obtain according to the storage region position of the first block chain data to position in first unified resource The first block chain data at address；It specifically, is open in the first block chain data or the second block chain data In the case where data, the first block chain data or the second block chain data are stored in the open region of account book；With And in the case where the first block chain data or the second block chain data are private data, the first block chain number According to or the second block chain data be stored in the privacy area of account book；The account is stored in the first block chain data In the case where in this open region, the first block chain data at first uniform resource location are obtained.

In the content of present invention, judging whether there is at least one second uniform resource location further comprises: root According to hierarchy attributes included by the first block chain data and predetermined hierarchical relationship tree to determine whether in the presence of described in At least one second uniform resource location.

In the content of present invention, when generating webpage associated with the first uniform resource location, block chain Hierarchy attributes included by data can also play the role of very important, it will according to layer included by the first block chain data Secondary attribute and predetermined hierarchical relationship tree are to determine whether there are at least one the second uniform resource locations.It is specific next The hierarchy attributes for seeing such as block chain data A are " insurance ", and predetermined hierarchical relationship tree table is bright that there are hierarchy attributes For the block chain data B of " insurance/block chain insurance ", then block chain data B is then the next stage block chain of block chain data A Data.If webpage read requests are will to be directed toward hierarchy attributes to grab the block chain data A that hierarchy attributes are " insurance " Uniform resource location for the block chain data B of " insurance/block chain insurance " also generates on webpage, i.e., generated It is the uniform resource location of the block chain data B of " insurance/block chain insurance " comprising being directed toward hierarchy attributes in webpage.

In addition, in the present embodiment in order to ensure containing corresponding unified resource positioningly in the index that is stored in caching The newest block chain data of location, in order to quickly and efficiently return to newest webpage to user or search engine, in the present invention Method provided by holding for searching for block chain data further comprises first embodiment 300 as shown in Figure 3 in order to update It indexes, specifically comprises the following steps: in caching

Step 310: being determined in the block chain based on the uniform resource location stored in each index and accordingly united Block chain data at one resource locator address.

Step 320: by data corresponding to the webpage stored in the block chain data and the index be compared with Determine whether the block chain data at the uniform resource location update.

In this step, it is had differences between data corresponding to the webpage stored in block chain data and the index When, show the block chain data at the updated uniform resource location.

Step 330: in the case that the block chain data at the uniform resource location are updated, in the index The middle block chain data webpage generated being updated to webpage associated with the uniform resource location according to update, And by second time information renovation be the block chain data renewal time.

The content of present invention can be realized using the embodiment updates corresponding index in the buffer.

Alternatively, the content of present invention can also realize the real-time update for indexing in caching using following examples:

Accordingly unify money in the block chain firstly, determining based on the uniform resource location stored in each index Block chain data at the positioning address of source.

Secondly, the modification time information of the block chain data is compared with the second temporal information in the index Whether updated with the block chain data at the determination uniform resource location.

Specifically, show when the second temporal information that the modification time information of the block chain data is not later than in the index Block chain data at the uniform resource location are not updated, when the modification time information of the block chain data is later than this Show that the block chain data at the uniform resource location have been updated when the second temporal information in index.

Third, the case where the modification time information of the block chain data is later than the second temporal information in the index Under, webpage associated with the uniform resource location is updated to the block chain data according to update in the index Webpage generated, and be the renewal time of the block chain data by second time information renovation.

The content of present invention can also real-time update indexes accordingly in the buffer using above-described embodiment.

Optionally, in order to ensure containing the newest of corresponding uniform resource location in the index that is stored in caching Block chain data, in order to quickly and efficiently return to newest webpage to user equipment or search engine, the content of present invention is mentioned The method for searching for block chain data supplied can also realize above-mentioned mesh using second embodiment 400 as shown in Figure 4 A 's.

In the method shown in Fig. 4 A, firstly, further including indicate to allow to return difference webpage the in webpage read requests One indicator, each of caching index further includes one or more difference webpages and corresponding with each difference webpage Time segment information.

400 concrete operations of method as shown in Figure 4 A are as follows:

Step 410: being determined in the block chain based on the uniform resource location stored in each index and accordingly united Block chain data at one resource locator address.

Step 420: by data corresponding to the webpage stored in the block chain data and the index be compared with Determine whether the block chain data at the uniform resource location update.

In this step, data corresponding to the webpage stored in the block chain data and the index are compared and are sentenced It is disconnected to whether there is data difference, the block chain having had updated at the uniform resource location is determined when there are data difference Data.

Step 430: the case where block chain data at the uniform resource location in the index are updated Under, phase is generated using the data difference between data corresponding to the webpage stored in the block chain data of update and the index The difference webpage answered, by the renewal time of second temporal information and block chain data together as with the difference webpage Corresponding time segment information.

Step 440: webpage associated with the uniform resource location is updated to the block chain number according to update It is the renewal time of the block chain data according to webpage generated, and by second time information renovation.

Therefore, the updated index includes uniform resource location, associated with the uniform resource location Webpage, the second temporal information, one or more difference webpages associated with the uniform resource location and with it is each The corresponding time segment information of a difference webpage.

In actual operation, if realizing the update to indexing in caching using second embodiment 400 shown in Fig. 4 A, There is index associated with first uniform resource location in the caching and the first time information is early In the case where second temporal information in the index, the method for searching for block chain data further include:

It whether there is the first indicator firstly, determining in the received webpage read requests of institute.

That is, showing what the search engine for issuing the webpage read requests or user used when there are the first indicator Browser allows to return to difference webpage.

Secondly, being believed there are in the case where the first indicator based on the first time in received webpage read requests Breath is corresponding with the time residual quantity to exist in the determination caching with the time residual quantity between second temporal information When one or more difference webpages, returned via the hypertext transfer protocol interface corresponding with the time residual quantity One or more difference webpages.

The above-mentioned steps of the content of present invention can the search node 117 as shown in Fig. 1 realize.

For example, it includes the first uniform resource location URLx, at the first time letter that search engine is sent to search node 117 When the webpage read requests of breath (for example, 18:30) and the first indicator, search node 117 searches whether exist in the buffer Index associated with URLx.The example of index associated with URLx in the buffer is shown in figure 4b, is specifically included URLx and corresponding webpage html_x, the second temporal information (for example, 19:00), within a predetermined period of time according to URLx Obtain multiple and different difference webpages (for example, △ html_1, △ html_2, △ html_3) and with these difference webpage phases Corresponding time segment information (for example, 18:45-19:00,18:30-18:45,18:10-18:30).Search node 117 is according to Time residual quantity (18:30-19:00) between one temporal information (for example, 18:30) and the second temporal information (for example, 19:00), And it is determined from multiple time segment informations (for example, 18:10-18:30,18:30-18:45,18:45-19:00) in the index There are two difference webpages in the buffer (that is, corresponding respectively to △ html_1 of 18:45-19:00,18:30-18:45, △ Html_2), then search node 117 via hypertext transfer protocol interface returns to the two difference webpages.

For another example, it includes the first uniform resource location URLx, first time that search engine is sent to search node 117 When the webpage read requests of information (for example, 08:20) and the first indicator, search node 117 searches whether to deposit in the buffer In index associated with URLx.In the case of predetermined amount of time is set as two small, exist and URLx phase in the buffer In the case where associated index, corresponding second temporal information (for example, 19:00) of URLx is checked, and also find URLx Corresponding multiple time segment informations (for example, 18:10-18:30,18:30-18:45,18:45-19:00), but in view of first Time residual quantity between temporal information (for example, 08:20) and the second temporal information (for example, 19:00) is considerably beyond described pre- Section of fixing time (for example, two hours), then search node 117 postpones webpage (for example, html_x) associated with URLx Search engine is returned to via hypertext transfer protocol interface in depositing.

In the content of present invention, in order to realize through the uniform resource location for block chain number associated there According to correct parsing, the content of present invention proposes the analysis mode for being used to specify the block chain data for block chain data configuration Attribute.For example, the attribute includes the data format name for indicating the data analysis method of the block chain data.

When stating chained address in realization, the Robots agreement abided by needed for following search engine is also needed.It is specific and Speech, Robots agreement are also referred to as crawler agreement, the robot protocol etc., and full name is " web crawlers exclusion criteria " (Robots Exclusion Protocol), website tells which page of search engine that can grab by Robots agreement, which page is not It can crawl.

Specific to the content of present invention, for every chained address in the portal site, it is also desirable to pass through Robots agreement Inform the chained address that search engine allows to traverse.The content of present invention using block chain data itself attribute (such as according to this Disclosed in summary of the invention block chain data include public data and private data) realize the search behavior for search engine Control, wherein public data and private data are stored in different location or the public data and described hidden of block chain Private data have different labels.

The alliances such as Fabric, Corda chain then all does access privilege control to whole data in all block chain data. It can be seen that block platform chain is for there is the data of different requirements all to do the same access control without different access The ability of control.And in general, usually using alliance's platform chain, access authority control is done to total data for enterprise-level block chain System causes external search engine that can not retrieve the disclosed information of needs.

Specifically, public data and private data are stored in the different location or public data and privacy number of block chain According to the implementation method with different labels can there are many kinds of.

For example, the content of present invention can distinguish multiple account books, such as by first account book labeled as public affairs This is made out a bill, i.e., only stores above-mentioned public data thereon, and other account books are labeled as privacy account book, is only stored thereon hidden Private data.Those skilled in the art is it is to be appreciated that the quantity of open account book and privacy account book can be according to needs on block chain The ratio dynamic configuration of disclosed data and private data.Thus, it is possible to realize the differentiation pair for the data in block chain network To be provided safeguard for the subsequent search service for the data on block chain.

In the case where the first block chain data are stored in open account book, obtain at the first uniform resource location First block chain data.The first block chain data at the first uniform resource location are stored in the situation in privacy account book Under, the first block chain data can not be obtained.

Alternatively, also first account book for example can be divided into two different regions, is stored on first region Public data, and private data is stored on Two Areas, it thus also can be realized for the data in block chain network Differentiation is treated, to provide safeguard for the subsequent search service for the data on block chain.

In the case where the first block chain data are stored in the open region of account book, obtain and positioned in the first unified resource The first block chain data at address；It, can not in the case where the first block chain data are stored in the privacy area of account book Obtain the first block chain data.
