Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, fig. 1 is a schematic flowchart of an embodiment of a method for processing a hypertext transfer protocol request according to the present invention, where the method for processing a hypertext transfer protocol request includes the following steps:
step S1, after the Web browser sends an HTTP request to the Web server, the Web browser abandons the receiving of the response information of the Web server for the HTTP request from the Web server;
in this embodiment, the Web browser is executed in a user terminal, and the user terminal may be, for example, a mobile phone, a computer, a tablet computer, a Personal Digital Assistant (PDA), a wearable device (e.g., a smart watch, smart glasses, etc.), or any other suitable electronic device. When a user uses the user terminal, the Web browser is triggered to send an HTTP request to the Web server, wherein the HTTP request is different from a common HTTP request, the HTTP request can enable the Web browser to obtain webpage related information returned by the Web server, the common HTTP request may not obtain the webpage related information returned by the Web server due to interruption and the like, and the HTTP request can be identified as the HTTP request so as to be distinguished from the common HTTP request.
In this embodiment, in the running process of the Web browser, a user may trigger the Web browser to send one HTTP request to the Web server, or continuously send a plurality of HTTP requests.
If the interruption does not occur according to the normal flow, the Web server returns response information to the Web browser according to the HTTP request, and if the interruption occurs, the Web browser cannot receive the corresponding response information. Whether the interruption occurs or not or whether the response information is returned to the Web browser by the Web server or not, the Web browser abandons the corresponding response information returned by the Web server, namely, the Web browser does not execute the operation of receiving the response information returned by the Web browser.
Step S2, the Web server saves the processing progress and the key node state of the HTTP request when processing the HTTP request;
in this embodiment, after receiving the HTTP request sent by the Web browser, the Web server performs an operation according to a normal flow, that is, performs a related processing operation on the HTTP request, acquires a processing progress and a key node state in a processing process, and stores the processing progress and the key node state in association with the HTTP request.
The processing progress is the progress of the Web server processing the HTTP request, and the key node state is, for example, a state of whether the request is successfully processed, a state of whether the requested Web page has been permanently moved to a new location, and the like, that is, the processing progress and the key node state are information related to the Web page. And then storing the acquired processing progress and the state of the key node for subsequent use.
Step S3, when the preset time after the Web browser sends the HTTP request arrives, the Web browser sends a pseudo HTTP request corresponding to the HTTP request to the Web server;
in this embodiment, after sending the HTTP request to the Web server, the Web browser does not perform an operation of receiving response information returned by the Web server, but enters a waiting state, and when a preset time after sending the HTTP request arrives, sends a dummy HTTP request corresponding to the HTTP request to the Web server, where the dummy HTTP request corresponds to the HTTP request, and the HTTP request may be considered as a real HTTP request.
The pseudo HTTP request is generated after the HTTP request, and the request information of the pseudo HTTP request coincides with the HTTP request so that the Web browser can obtain response information of the HTTP request from the Web server regardless of occurrence of an interrupt. Among other things, pseudo HTTP requests may be identified to correlate with HTTP requests and to distinguish from ordinary HTTP requests.
Step S4, after receiving the pseudo HTTP request, the Web server obtains the saved processing progress and key node state corresponding to the HTTP request according to the corresponding relation between the pseudo HTTP request and the HTTP request;
in this embodiment, after receiving the pseudo HTTP request sent by the Web browser, the Web server parses the pseudo HTTP request, obtains request information of the pseudo HTTP request through the parsed content, and compares the request information with request information of the stored HTTP request to obtain whether the pseudo HTTP request corresponds to the request information of the stored HTTP request. If the two are corresponding, the processing progress and the key node state saved during the processing of the HTTP request can be obtained, and if the two are not corresponding, the corresponding processing progress and the key node state cannot be directly obtained.
In step S5, the Web server returns the acquired processing progress and key node status to the Web browser as the actual response information of the pseudo HTTP request.
In this embodiment, after the Web server acquires the processing progress and the key node state corresponding to the determined HTTP request, the acquired processing progress and key node state are used as real response information of the pseudo HTTP request, and then returned to the Web browser.
Compared with the prior art, after the Web browser sends the HTTP request to the Web server, the Web browser of this embodiment enters a waiting state without receiving response information of the Web server for the HTTP request, and at the same time, the Web server stores the corresponding processing progress and the key node state until a preset time is reached, at this time, to avoid an interruption or an error report, the Web browser sends a pseudo HTTP request corresponding to the HTTP request to the Web server, so that the server determines the corresponding HTTP request according to the pseudo HTTP request, and then can acquire the processing progress and the key node state of the corresponding HTTP request, and finally the Web server can return the acquired processing progress and the key node state to the Web browser, thereby avoiding an interruption or an error report between the Web browser and the Web server, and the Web browser can acquire the processing progress and the key node state corresponding to the HTTP request, compared with the method for increasing the time length of the gateway overtime, the method for increasing the time length of the gateway does not need to increase the time length of the gateway (namely the time length of the existing gateway can be kept unchanged), so that related settings do not need to be changed, and network resources are saved.
In a preferred embodiment, on the basis of the embodiment of fig. 1, the step S1 is preceded by:
the Web browser generates the HTTP request and configures a first identifier of the HTTP request at the same time, and encapsulates the first identifier in the HTTP request;
the step S3 includes: before the preset time after the Web browser sends the HTTP request is reached, when a pseudo HTTP request corresponding to the HTTP request is generated, configuring a second identifier of the pseudo HTTP request, and encapsulating the second identifier in the pseudo HTTP request, wherein the second identifier is associated with the first identifier;
in this embodiment, while generating an HTTP request, the Web browser configures a first identifier for the generated HTTP request, identifies the HTTP request with the first identifier, and encapsulates the first identifier in the HTTP request, for example, encapsulates the first identifier in a protocol header of the HTTP request.
In addition, before the preset time after the HTTP request is sent is reached, when a pseudo HTTP request corresponding to the HTTP request is generated, a second identifier is configured for the pseudo HTTP request at the same time, the pseudo HTTP request is identified by the second identifier, and then the second identifier is encapsulated in the pseudo HTTP request, for example, the second identifier is encapsulated in a protocol header of the pseudo HTTP request. Wherein the second identifier is associated with the first identifier, and the first identifier associated with the second identifier can be found through the second identifier.
Preferably, as shown in fig. 2, on the basis of the foregoing embodiment, the foregoing step S4 includes:
s41, after receiving the pseudo HTTP request, the Web server analyzes the pseudo HTTP request and acquires a second identifier in the HTTP request;
and S42, determining the HTTP request corresponding to the first identifier associated with the second identifier, and acquiring the stored processing progress and the key node state corresponding to the determined HTTP request.
In this embodiment, since the HTTP request and the pseudo HTTP request are both encapsulated with the identifier, after the pseudo HTTP request is received by the Web server, the pseudo HTTP request is analyzed, for example, a protocol header of the pseudo HTTP request is analyzed, so that the second identifier can be obtained. In addition, the Web server analyzes the HTTP request after receiving the HTTP request and caches the first identifier obtained by analysis. Therefore, the HTTP request to which the first identifier belongs can be found through the association relationship between the second identifier and the first identifier, and finally, the processing progress and the key node state corresponding to the HTTP request, which are stored, are obtained through the found HTTP request.
In the embodiment, corresponding identifiers are configured for the HTTP request and the pseudo HTTP request respectively when the HTTP request and the pseudo HTTP request are generated, and the identifiers of the HTTP request and the corresponding pseudo HTTP request are associated, so that the HTTP request can be found through the identifier in the pseudo HTTP request in the subsequent Web server, and thus, the processing progress and the key node state corresponding to the HTTP request are obtained.
In a preferred embodiment, on the basis of the embodiment of fig. 1, the step S3 is followed by:
after receiving the pseudo HTTP request, if no HTTP request corresponds to the pseudo HTTP request, the Web server returns response information in a preset format to the Web browser, or the Web server takes the pseudo HTTP request as an HTTP request to process and sends an instruction for resending the pseudo HTTP request to the Web browser;
and when the preset time after the Web browser sends the pseudo HTTP request arrives, sending the pseudo HTTP request consistent with the pseudo HTTP request to the Web server again by the Web browser.
In this embodiment, after receiving the pseudo HTTP request, the Web server analyzes whether there is a corresponding HTTP request by analyzing, for example, performing association lookup through an identifier, and if it is analyzed that there is no HTTP request corresponding to the pseudo HTTP request at present (for example, the Web server fails to analyze and obtain a corresponding HTTP request due to an error in the process of processing the HTTP request or due to a failure to store a processing result, etc.);
in an embodiment, the Web server may return response information in a preset format to inform that the Web browser does not currently have a corresponding HTTP request, for example, the response information in the preset format is response information with empty response content.
In another embodiment, the Web server processes the pseudo HTTP request as one HTTP request, namely, acquiring the processing progress and the key node state of the pseudo HTTP request in the processing process, saving the processing progress and the key node state of the pseudo HTTP request, and sends an instruction to resend the pseudo HTTP request to the Web browser, returns to step S4 described above and loops, that is, after receiving the instruction, the Web browser sends a pseudo HTTP request to the Web server again, after receiving the pseudo HTTP request, the Web server determines an HTTP request corresponding to the pseudo HTTP request to obtain a processing progress of the HTTP request and a key node state, namely, the loop step is executed until the process progress of the HTTP request is obtained and the state of the key node is finished, or whether the Web browser acquires the processing progress of the HTTP request and the state of the key node or not, the Web server sends a preset number of instructions for resending the pseudo HTTP request to the Web browser and then finishes the process.

When a user uses the user terminal, the Web browser is triggered to send an HTTP request to the Web server, wherein the HTTP request is different from a common HTTP request, the HTTP request can enable the Web browser to obtain webpage related information returned by the Web server, the common HTTP request may not obtain the webpage related information returned by the Web server due to interruption and the like, and the HTTP request can be identified as the HTTP request so as to be distinguished from the common HTTP request.
In this embodiment, in the running process of the Web browser, a user may trigger the Web browser to send one HTTP request to the Web server, or continuously send a plurality of HTTP requests.
If the interruption does not occur, the Web server returns response information to the Web browser according to the HTTP request, and if the interruption occurs, the Web browser cannot receive the corresponding response information. Whether the interruption occurs or not or whether the response information is returned to the Web browser by the Web server or not, the Web browser abandons the corresponding response information returned by the Web server, namely, the Web browser does not execute the operation of receiving the response information returned by the Web browser.
