Technical Field
The invention relates to the technical field of internet data interaction processing, in particular to a method, equipment and storage medium for suspending http requests in batches.
Background
As the website interaction function becomes more complex, the data interaction between the website and the server becomes frequent, when the user performs the interaction, it is assumed that the user wants to give up the interaction and perform other operations due to the slow response speed of the interface, or when the user enters a page due to misoperation, the page initiates a plurality of requests, and at this time, the user switches to other pages, and the requests are still continued, so that on one hand, the interaction requests which are useless for the current operation of the user increase the pressure of the server, and on the other hand, if the requests fail, the errors are directly thrown to the current interface of the user, and the user experience is poor. Thus, when faced with the above-described situation, how to effectively suspend these requests to improve user experience and website performance has become the focus of current research.
The existing jQuery provides a single ajax request suspension method, namely an abart method, wherein the abart method cannot directly suspend requests in batches, and in the existing project, suspension requests need to use the abart method for the requests in each controller respectively and execute suspension operation on the unfinished requests when appropriate. If a request is intercepted at the outer layer and an abort is attempted, only a single request can be aborted, for example: if three requests are sent simultaneously by a page, when a callback function of which the request is completed is received, it cannot be judged which request is completed, and no matter how many times of the function is called, the last sent and unfinished request can be stopped.
Therefore, when the above method is adopted, if a plurality of requests need to be suspended at the same time, the above method cannot meet the requirement, and for large-scale projects, the above method cannot provide a suspending request function well, and how to realize batch suspending requests in large-scale projects is a problem to be solved currently.

s2, judging whether the monitored request meets the registration condition, if yes, executing a step S3, otherwise returning to the step S1, and if the monitored request occurs in the page jumping process, not meeting the registration condition;
s3, based on a callback function before request transmission, all requests meeting registration conditions are registered in the object before the request transmission, and the specific process of registering the requests is as follows:
s31, creating an empty object;
s32, if the popup creation event is monitored, recording the ID of the popup into the object, and then executing step S33;
if the popup creation event is not monitored, directly executing step S33;
s33, triggering a callback function before the request is sent, registering a request to be sent in the callback function before the request is sent, taking the URL of the request as a key and taking an XMLHttpRequest object as a value corresponding to the key;
s4, based on the request completion callback function, deleting the corresponding completed request information in the object after the request is completed, specifically triggering the callback function after the request is completed, and transmitting back the URL of the request by the request completion callback function; then deleting the corresponding request in the object according to the returned URL information;
s5, when a batch suspension request scene is triggered (the batch suspension request scene comprises successful page jump and popup window closing), sequentially performing suspension operation on the rest requests in the current object:
if the triggered batch suspension request scene is that the page jump is successful, changing the page jump state mark from true to false, namely that the page jump is successful; after monitoring a page skip success event, sequentially carrying out suspension operation on all requests in the current object;
if the triggered batch suspension request scene is a popup window closing, after a popup window closing event is monitored, suspension operation is sequentially carried out on all requests in the object recorded with the popup window ID.
Based on the technical scheme provided by the invention, the embodiment obtains the completed request information by expanding the complex callback function in the ajaxSetup of the jQuery, thereby obtaining the set of the incomplete requests, and then carrying out batch suspension operation on the incomplete requests when triggering the scene requiring batch suspension of the requests. The method specifically includes monitoring requests of items in an item entry file, recording all requested information into an Obj object, obtaining completed request information by expanding parameters of a complex function, deleting the completed request information from the Obj according to the information, and recording all the completed requests in the Obj in a state of incomplete requests. When a scene requiring batch suspension requests is triggered, suspension operations are sequentially carried out on all requests recorded in Obj, and the function of batch suspension requests can be realized.
The specific process is shown in fig. 2:
1. and setting an ajax request monitoring function in the project entry file, and setting callback functions before request sending and after request completion.
2. In the callback function before the request is sent, registering the request to be sent, recording the request into an Obj object, using url of the request as a key, and using an XMLHttpRequest object as a value corresponding to the key.
3. Modifying source codes corresponding to ajexsetup in jQuery and triggering complex callback functions, and returning url of the request. And after the request is completed, triggering a corresponding callback function, taking url information of the completed request, and deleting the corresponding request information in Obj based on the url information.
4. When the batch suspension requests are needed, suspension operation is sequentially carried out on the requests recorded in the Obj object.
In this embodiment, after a batch request is made for a user entering the interface a, the user leaves the interface a to enter the interface B, and triggers a scenario called by the interface B, experiments are performed on a Chrome with version 76, and when the technical scheme of the present invention is used and the technical scheme of the present invention is not used in the scenario, response time called by the interface B is recorded, so that data as shown in table 1 are obtained:

3. In the callback function after the request is finished, the completed request is logged off.
3.1 modifying source codes of triggering complex callback functions in the ajexsetup function in the jQuery, and returning url of the request.
And 3.2, deleting the corresponding request data in the Object according to the returned url when the complex callback function of the monitoring request in the entry file is triggered.
4. Before the page jumps, an angular $ stateChangeStart event is triggered, and after the event is monitored, the state of the page is marked with an identifier iststatechange. If the sending request is monitored in the page skip process, the sending request is not registered in the Object.
5. After the page is successfully jumped, an annular $stateChangeSuccess event is triggered, and after the event is monitored, a suspension method is sequentially called for record requests in objects, so that a batch suspension function of incomplete requests is realized.
2. When the current page closes the popup window, a request sent in the batch suspension popup window is performed, as shown in fig. 4:
1. all requests of the project are monitored in the project entry file, and callback functions before the request is sent and when the request is completed are set.
2. After monitoring for a create pop event, the request sent in the pop is recorded.
2.1 creating an empty Object for recording the information of the request to be sent.
2.2 after hearing a popup window open event, an Object id Object is generated for recording the request in this popup window, where id is the id of the popup window.
2.3 when the callback function before the request is sent is triggered, the request is registered in the Object [ id ] Object, url of the request is used as a key, and the XMLHttpRequest Object is used as a value corresponding to the key.
3. In the callback function after the request is finished, the completed request is logged off.
3.1 modifying source codes corresponding to ajexsetup in jQuery and triggering complex callback functions, and returning url of the request.
3.2 when the complete callback function of the monitoring request in the entry file is triggered, according to url information of the returned request, judging that if the request is recorded in the Object [ id ], deleting the information of the completed request from the Object.
4. When the window closing event is monitored, an abort method is sequentially called for the requests recorded in the outstanding requests, namely the objects, sent in the window, so that the batch abort request function during window closing is realized.
The embodiment also discloses equipment for suspending http requests in batches, which comprises a processor, wherein the processor is in communication connection with a memory, the memory stores a computer readable program, and the batch suspending http request method is realized when the processor executes the computer readable program.
