Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments of the present disclosure, shall fall within the scope of protection of the present application.
Fig. 1 is a schematic diagram of a web crawler process involved in a practical application scenario of the solution of the present specification. For example, when a user wants to crawl content related to a topic, the user can set information such as a website to be crawled, field information to be crawled, website rules, and field rules through a configuration template. After the configuration template is set, a list page including detailed page websites, field information and the like is crawled according to configuration information, and further, contents in the detailed page websites are crawled according to the configuration information to obtain designated information.
It should be noted that the configuration template is designed based on a configuration database and a visual interface, and can be used for a user to visually fill in configuration information, and the configuration template can preset configuration information for crawling various website rules and field rules. In addition, the configuration template shown in fig. 1 is shown in the form of a server, and the characterization configuration template may run on the server, which is not only a single server, but also may adopt a cluster or distributed architecture (these two architectures are not shown in the figure).
Based on the above-described scenarios, the following describes the embodiments of the present specification in detail.
Fig. 2 is a schematic flow chart of a web crawler method provided in an embodiment of the present specification, where the method specifically includes the following steps:
step S201: setting configuration information based on the configuration template; wherein the configuration information includes list page configuration information and detail page configuration information.
The configuration template may be configured with configuration information via a UI (User Interface). The configuration information may include website related configuration information (e.g., URL rules), web page configuration information (e.g., web page encoding rules), and so on. The configuration template can add configuration information according to the requirements of the user, for example, the key field 'house price' configured by the user for the first time, and the user wants to further know the related information of 'loan', so the user can further add the key field 'loan' for further crawling; therefore, different requirements of users can be met, the application range is enlarged, meanwhile, the codes do not need to be modified, the crawler operation is simplified, and the crawling efficiency is improved.
It should be noted that, in practical applications, the list configuration information and the detailed page configuration information are not strictly distinguished, and the field information in the detailed page to be crawled may also be set in the list page configuration information.
Step S203: and crawling the list page information according to the list page configuration information.
The list page mainly contains information of a web page address (URL, Uniform Resource Location) to be crawled. The web addresses in the list page include web addresses specified by the user and also web addresses obtained by crawling. Further, in order to avoid repeated crawling, the websites with crawling and the websites without crawling are stored separately in the list page.
①, the initial URL address can be manually designated by the user, or can be determined by one or more initial crawled web pages designated by the user. ②, according to the initial URL, crawls the web page in the corresponding URL address and obtains a new URL.after obtaining the initial URL address, the web page is stored in the original list page after crawling the web page in the corresponding URL address, and the new URL address is found while crawling the web page, and the crawled URL address is stored in a URL list page for the process of deduplication and judgment of crawling. ③, the new URL is placed in the queue of the URL list page.after obtaining the next new URL address in ②, the new URL address is placed in the URL list page queue. ④, reads the new URL from the queue, and according to the new URL, crawls the new URL, and repeats the process.
Step S205: and crawling specified information based on the acquired list page information and the detailed page configuration information.
The detailed page referred to herein may be understood as a web site page (i.e., URL) designated by a user, and crawling of the designated information is performed based on the designated web page. The specified information may be a user-specified type of subject, specific field information, or the like. In the crawling process, list page information is crawled according to detailed page configuration information, decoupling is achieved between a configuration template and a bottom layer code (for example, the title of an article is crawled, the configuration can be { ' field ', ' type ', ' xpath ', ' val ': tr [1]/td [2]/a/text () '), a user can adjust the configuration information in the crawling process, the bottom layer code does not need to be changed, and crawler efficiency can be effectively improved.
According to the embodiment, the configuration information which is originally required to be fixed in the code is extracted and decoupled with the code, so that the dependency of the code and the crawler configuration is reduced, the rule and the content of the webpage to be crawled do not need to be analyzed by a user, and the purpose of meeting the newly added requirement without modifying the code can be met by generating the preset configuration template for configuration; the maintenance cost of the code is reduced, and the utilization efficiency of the code is improved. Meanwhile, the configuration template is preset with configuration information corresponding to various website rules, field rules, webpage coding types and the like, so that various requirements and expansion requirements of users can be met, and the application range of codes is expanded.
In one or more embodiments of the present disclosure, the configuration template is preset according to a code specification, and is used to set the configuration information.
In order to meet the requirement of user-defined configuration information, various configuration information ports are preset in the configuration template, and the configuration template and the bottom layer codes can be decoupled corresponding to the bottom layer codes with different functions. Under the condition that a user does not know the bottom layer code, the user can set the specific information which the user wants to crawl based on the configuration template, and the crawling work efficiency can be effectively improved.
In one or more embodiments of the present specification, the list page configuration information includes: web address to be crawled and website page turning rules; the detailed page configuration information includes: field information, field rules.
As described above, the list page contains the website information (i.e., URL) to be crawled. In the actual crawling process, crawling is required according to an initial URL, and the initial URL can be directly provided by a user or determined according to some initial crawling webpage or initial crawling webpages specified by the user. To acquire the website, a page turning rule that may exist in the web page needs to be preset so as to more easily crawl to the desired website.
In the detailed page configuration information, a rule related to specific crawling of specified information, for example, crawled subject information, a URL rule, or the like, is often set.
In one or more embodiments of the present specification, the crawling a list page according to the list page configuration information may include, as shown in fig. 3: step S301: acquiring a task address; step S303: reading the website to be crawled and/or the website page turning rule according to the task address; step S305: and crawling field information and detailed page websites contained in the list page information according to the websites to be crawled and/or the website page turning rules.
Specifically, the task address may be a unique number automatically assigned to the task by the system, and for example, after the number is set to 1 from the first task address, the other task addresses are sequentially incremented.
In one or more embodiments of the present specification, the website page turning rule includes: directly extracting the website or obtaining the website through simulated clicking.
In practical application, the page turning operation of the website can be realized by simulating clicking, and some website information is directly in the webpage content. The webpage turning rules for different websites are different and need to be predefined in the configuration template. For example, if a connection button of "next page" is included in the current web page, a specific URL can be obtained by simulating a click if the web address of "next page" is to be crawled.
In one or more embodiments of the present specification, the crawling of the specific information based on the acquired list page information and the detailed page configuration information may include, as shown in fig. 4, the following steps: step S401: preprocessing field information and detailed page websites contained in the list page information according to a preset processing rule; step S403: and crawling corresponding specified information according to the preprocessing result and the field rule.
The pre-processing rules referred to herein may include pre-processing of the URL (i.e., parsing the URL), analysis of the data format, parsing of the web page encoding, and extraction of valuable data.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the embodiments of the apparatus, the electronic device, and the nonvolatile computer storage medium, since they are substantially similar to the embodiments of the method, the description is simple, and the relevant points can be referred to the partial description of the embodiments of the method.
The apparatus, the electronic device, the nonvolatile computer storage medium and the method provided in the embodiments of the present description correspond to each other, and therefore, the apparatus, the electronic device, and the nonvolatile computer storage medium also have similar advantageous technical effects to the corresponding method.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the various elements may be implemented in the same one or more software and/or hardware implementations in implementing one or more embodiments of the present description.
As will be appreciated by one skilled in the art, the present specification embodiments may be provided as a method, system, or computer program product. Accordingly, embodiments of the present description may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, embodiments of the present description may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and so forth) having computer-usable program code embodied therein.
The description has been presented with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the description. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.
Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
This description may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The specification may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network.
