step 201, a request loading processor extracts a field from request log information of a web server, and generates an http request according to the extracted field and a preset http request template; or the request loading processor receives input http information and generates an http request according to the http information and a preset http request template.
Specifically, in the preferred embodiment, more than one request loading processor is provided, for each request loading processor, a user needs to store a request log file of a web server into the request loading processor in advance, the content of the request log file of the web server is a log stored by the web server according to a received http request when the user sends the http request to the web server through a browser, the log belongs to an online real http request log, the request log file of the web server contains request log information of more than one web server, and the request loading processor extracts a plurality of fields from the request log information of the web server according to a preset policy, such as a request type, a request address, a data coding mode that the browser can decode, cookie data, a browser type, a source URL, a host in an initial URL, a port and the like; the preset strategy can be to extract fields referenced by quotation marks in the character string or fields after spaces in the character string; after extracting fields from request log information of a web server, a request loading processor fills the extracted fields into an http request template according to the http request template preset by a user to generate an http request; here, the request loading processor needs to generate http requests of the same number according to the number of the request log information of the web servers in the request log file of the web server, that is, an http request is generated correspondingly for the request log information of each web server.
Or, requesting the loading processor to receive http information input by a user, wherein the http information comprises: request type, request address, data encoding mode which can be decoded by the browser, cookie data, browser type, source URL, host and port in initial URL, etc.; then, the request loading processor fills http information input by the user into an http request template preset by the user to generate an http request; here, the request loading processor supports http information input by a user, and can conveniently realize and construct various types of http requests for testing the functions of the reverse proxy server.
For example, there is the following request log information of the web server:
61.236.32.126--[05/Mar/2007:00:00:00+0800]″GET/index.php?tn=btplus_cbHTTP/1.1″2001467mod_gzip:54pct.″www.host.com″″www.referer.com″BAIDUID=141550BC0DD29E1F93BFD49836DA40CC″Mozilla/4.0(compatible;MSIE 6.0;Windows NT 5.1;SV1)″
wherein, GET is a request type to replace a method field in an http request template; php; gzip is a data coding mode which can be decoded by the browser, and replaces an Accept-Encoding field in an http request template; BAIDUID =141550BC0DD29E1F93BFD49836DA40CC is cookie data, and replaces a cookie field in an http request template; mozilla/4.0(compatible; MSIE 6.0; Windows NT 5.1; SV1 is browser type, replacing the User-Agent field in the http request template; www.host.com is the Host and port in the initial URL, replacing the Host field in the http request template; www.referer.com is the source URL, replacing the refer field in the http request template; furthermore, the Accept field in the http request template is fixed as text/html, application/xhtml + xml, application/xml, (+) q =0.9,/, q = 0.8.

″GET//index.php?tn=btplus_cb HTTP/1.1\r\nHost:www.host.com\r\nAccept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\nAccept-Encoding:gzip,deflate\r\nReferer:www.referer.com\r\nCookie:BAIDUID=141550BC0DD29E1F93BFD49836DA40CC;\r\nUser-Agent:Mozilla/4.0(compatible;MSIE6.0;WindowsNT 5.1;SV1)\r\n\r\n″。
for example, the request loading processor may receive http information entered by the user as follows:
GET/testbfe.php HTTP/1.1Host:db-testing-oped3001.db01.baidu.com:8901User-Agent:Mozilla/5.0(windows NT 5.1;rv:3.0)Gecko/20100101FireFox/13.0.1Accept-Encoding:gzip,deflateConnection:keep-aliveCookie:BAIDU=ABEE505768E4367875D6382A71939FEB:FG=1;BDUT=tbjh0EB0DD6C71BB689AC4C1C1307CFDB346138b7d734011;USERID=0cac808c2ebd401391dc4d87;Hm_lvt_t46af353ab5a92ddf70d8368b2529c10=1342609618035;Hm_lvt_e7617bc79ca305e55d9b5d393123de33=1341297466246;6a05b31484fdc3f8a9edb6307d81ef7a=706f5996fac620d8aa113313a034898a0881a5d4%3A4%3A%7Bi%3A0%3Bs%3A5%3A5%3A%22admin%22%3Bi%3A1%3Bs%3A5%3A%22admin%22%3Bi%3A2%3Bi%3A2592000%3Bi%3A3%3Ba3A0%3A%7B%7D%7D;UUAPTGC=TGT-602800-EOC3dchi70EyurqslcFYCKJlzaNuPFImGqsprpFoIB6N7RfbEF-vvap
step 202, the response playback processor stores the received http request, forwards the http request to the web server, and receives response information returned by the web server; the response playback processor and the request loading processor store the response information and the corresponding relation between the response information and the http request.
Specifically, the user sets a switch in advance in the response playback processor, the switch being used to control the operation mode of the response playback processor, and the switch may be implemented by setting an attribute of the response playback processor, for example, when a field value of status in the attribute of the response playback processor is set to 1, the operation mode of the response playback processor is a recording mode, the information recording function is turned on, when a field value of status in the attribute of the response playback processor is set to 0, the operation mode of the response playback processor is a playback mode, and the information playback function is turned on.
When the operation mode of the response playback processor is set to the recording mode, recording of response information is required, and as shown in fig. 3, the specific recording process of response information is as follows:
firstly, a response playback processor receives an http request, wherein the http request can be an http request sent by a request loading processor; the request loading processor can send the generated http request to the response playback processor according to the IP address and the port, a plurality of request loading processors can send the http request to the response playback processor in sequence, and a plurality of request loading processors can also send the http request to the response playback processor at the same time; alternatively, the user may send an http request to the replay handler via the browser, so that the http request received by the replay handler is an http request sent by the browser.
Then, on one hand, the response playback processor saves the received http request to a local request file, wherein when the response playback processor saves the received http request, the response playback processor needs to save the http request according to a receiving sequence; for example, after receiving the http request from the requesting loader a, the replay handler saves the http request in a request file, and then after receiving the http request from the requesting loader B, saves the http request in a request file, where the http request is located after the http request from the requesting loader a. And on the other hand, the response playback processor sequentially sends the received http requests to the corresponding web servers according to the IP addresses and ports of the web servers preset by the user and the receiving sequence of the http requests.
Finally, the web server responds after receiving the http request, constructs response information corresponding to the http request and sends the response information to the response playback processor; here, when the response playback processor sends the received http request to the web server, a serial sending mode is adopted, that is, after the response playback processor sends an http request, the response playback processor waits for receiving response information returned by the web server, and when the response information returned by the web server is received, the response playback processor sends the next http request to the web server, and so on; therefore, the response playback processor can be ensured that the received response information is the response information corresponding to the http request after the response playback processor sends the http request, so that the response playback processor can establish the corresponding relation between the http request and the response information and store the corresponding relation between the http request and the response information into a local response file; meanwhile, the response playback processor saves the received response information in the response file according to the reception order.
After the response playback processor sends all the received http requests and receives the response information corresponding to all the http requests, the recording work of the response playback processor is considered to be finished, then the recorded prompt mail is sent to the user according to the set mailbox, the user can modify the field value of status in the attribute of the response playback processor from 1 to 0, the working mode of the response playback processor is set to be a playback mode, and meanwhile, the response information stored in the response playback file of the response playback processor and the corresponding relation between the http request and the response information are copied to the request loading processor corresponding to the http request, so that the request loading processor stores the generated http request and the corresponding response information.
In the preferred embodiment, the response playback processor can record the response information only once, and can directly utilize the pre-recorded response information when the reverse proxy server is tested subsequently.
It should be noted that the above steps 201 to 202 are processes of requesting the loading processor to generate an http request and responding the playback processor to record response information, and belong to a preparation stage in a reverse proxy server test process, and a real test stage of the reverse proxy server is step 203 and step 205 described below; the http request and the response information may be generated only once and recorded once, and when the reverse proxy server is tested, the step 203 may be directly executed by directly using the http request and the response information.
Step 203, the request loading processor sends the pre-generated http request to the reverse proxy server.
Specifically, a user configures the sending frequency of the http request on the request loading processor in advance according to the test requirement; after the response playback processor records the response information, the reverse proxy server can be tested.
As shown in fig. 4, when testing the reverse proxy server, each request loading processor sends a generated http request to the reverse proxy server according to a preset http request sending frequency and a local http request generation sequence; here, there may be more than one request loading processor in the preferred embodiment, so that when the reverse proxy server is tested, some http requests sent by the request loading processors to the reverse proxy server are generated according to the request log information of the web server, and the rest http requests sent by the request loading processors to the reverse proxy server are generated according to the http information input by the user.
And step 204, the reverse proxy server forwards the received http request to the response playback processor, receives the pre-recorded response information returned by the response playback processor after receiving the http request, and forwards the response information to the corresponding request loading processor.
Specifically, as shown in fig. 4, after receiving the http request sent by the request loading processor, the reverse proxy server forwards the http request to the response playback processor, and the response playback processor finds the response information corresponding to the received http request according to the correspondence between the locally stored http request and the response information, and then returns the found response information to the reverse proxy server. Here, after receiving the http request, the reverse proxy server establishes a session channel for each http request, where the session channel is used as an interaction channel between the request loading processor, the reverse proxy server, and the response playback processor, and through the session channel, the reverse proxy server may forward the received http request to the response playback processor, then receive response information returned by the response playback processor, and send the response information to the request loading processor that sent the http request; in the process of the interaction of the http request and the response information, a session channel between the request loading processor and the reverse proxy server and a session channel between the reverse proxy server and the response playback processor exist all the time until the reverse proxy server sends the response information returned by the response playback processor to the request loading processor, namely after the complete response session is completed, the reverse proxy server releases the session channel established for the http request, and the established different session channels do not influence each other, so that the reverse proxy server is ensured to be capable of forwarding the received response information to the request loading processor corresponding to the http request corresponding to the response information.
In the preferred embodiment, the response playback processor records the real response information on the web server in advance, so that the web server is not required to send the response information to the reverse proxy server when the reverse proxy server is tested, and the response playback processor replaces the work of the web server and sends the pre-recorded response information to the reverse proxy server.
When the response playback processor sends the response information to the reverse proxy server, the response playback processor can send the response information according to a preset sending delay fixed value; or, since the response speeds of the web servers are different under different request pressures, in order to achieve that the response playback processor can better simulate the work of the web server, a user needs to configure a sending delay interval of the response information in the web server in advance according to a test requirement, after the web server receives an http request from the reverse proxy server, a specific time value can be randomly selected in the preset sending delay interval, and then the response information is sent to the reverse proxy server according to the selected specific time value as the sending delay.
Step 205, the request loading processor compares the response information received from the reverse proxy server with the locally preset response information, and obtains the test result of the reverse proxy server according to the comparison result.
Specifically, a plurality of response time periods are set in the request loading processor in advance, such as: 0-1000 ms, 1000-2000 ms, 2000-5000 ms, more than 5000 ms.
Because the request loading processor sends http requests to the reverse proxy server according to the sequence, and the reverse proxy server also forwards http requests to the response playback processor according to the sequence of receiving http requests, after receiving response information from the reverse proxy server, the request loading processor can find corresponding http requests according to the receiving sequence of the response information, then finds the response information corresponding to the http requests in the corresponding relationship between the locally stored http requests and the response information, compares the found response information with the response information received from the reverse proxy server, and judges whether the information in the two response information is the same.
If the information in the two response messages is different, the response messages forwarded by the reverse proxy server are not in accordance with expectations, and the function of the reverse proxy server is abnormal, so that an alarm mail aiming at the abnormality needs to be sent to a preset user mailbox to alarm a user, so that the user can debug the reverse proxy server; the alarm mail comprises the following contents: the method comprises the steps of receiving abnormal response information from a reverse proxy server, an http request corresponding to the abnormal response information, and response information corresponding to the http request stored locally.
If the information in the two response messages is the same, the response messages forwarded by the reverse proxy server are in accordance with expectations, and the function of the reverse proxy server is normal, so that the request loading processor needs to send the test report to a preset user mailbox; wherein, the test report includes the relevant function data of the reverse proxy server, and the relevant function data includes the following contents: the method comprises the steps of requesting to load the number of http requests sent by a server, the number of response information corresponding to each response time period, the average value of response time and the return value in the received response information.
After each http request is sent by the request loading processor, a corresponding timer is started, the timer is stopped until response information corresponding to the http request is received, then response time is determined according to the time of the timer, the response time period where the response time is located is judged, and then the counter value of the response time period is increased by 1. The request loading processor may also calculate an average of the response times of http requests in dependence on the determined response times. The request loading processor receives a response message, wherein a message header in the response message carries a return value of the http request, the return value refers to an http protocol state code and mainly comprises the following five types of return values: a return value of 1xx, indicating retention; a return value of 2xx indicating successful receipt of the request; the return value is 3xx, which indicates that the user needs to further refine the request to complete the request; the return value is 4xx, which represents that the user requests an error; the return value is 5xx, indicating a reverse proxy error.
To implement the above system, as shown in fig. 1, in the test system of the reverse proxy:
a request loading processor 10 for sending a pre-generated http request to a reverse proxy server 12;
the reverse proxy server 12 is configured to forward the received http request to the response playback processor 11, receive pre-recorded response information returned by the response playback processor 11 after receiving the http request, and forward the response information to the request loading processor 10;
the request loading processor 10 is further configured to compare the response information received from the reverse proxy server 12 with locally preset response information, and obtain a test result of the reverse proxy server 12 according to the comparison result.
The request loading processor 10 generates an http request in advance, specifically: the method comprises the steps of pre-storing a request log file of a web server, wherein the request log file of the web server comprises request log information of the web server; extracting fields from request log information of the web server; and filling a preset http request template by using the extracted field to generate an http request.
Or, the request loading processor 10 generates an http request in advance, specifically: receiving http information input by a user; and filling a preset http request template by using http information input by a user to generate an http request.
The response playback processor 11 records response information in advance, specifically: receiving and storing an http request sent by a request loading processor or a browser; forwarding the received http request to a web server, and receiving response information corresponding to the http request returned by the web server; and storing the response information and the corresponding relation between the response information and the http request.
The response information is preset in the request loading processor 10, and specifically includes: the request loading processor receives response information copied from the response playback processor and the corresponding relation between the response information and the http request.
Wherein, the response playback processor 11 returns the pre-recorded response information after receiving the http request, specifically: finding response information corresponding to the http request according to a corresponding relation between a preset http request and the response information; and returning the found response information to the reverse proxy server according to a preset sending delay fixed value or a random value in a sending delay interval.
