Detailed Description
Example 1
An auction platform high concurrency optimization processing system for an applet end comprises a design request interface, a restart and overload protection mechanism, data security and a WebSocket protocol under high concurrency;
as shown in fig. 1, the design request interface refers to a mobile applet auction page divided into two parts: one is a small program front-end service platform which comprises a merchant parking, a shot issuing, an auction holder registration and registration, an auction holder payment guarantee, an auction participation and an auction obtaining result; the other is a server-side background interface participating in auction, the background interface is used for supporting front-end services and enabling the front-end services to be smoothly realized, the small program front-end service platform improves response speed through CDN content distribution, the server-side background interface requests to adopt memory-level operation, all bid data are stored in a memory database firstly, and then are stored in a system database in an asynchronous writing mode to improve storage speed, the asynchronous writing mode adopts a mode of putting data in a cache, the data of the database are not immediately stored, but queue storage is used for realizing, the request interface can greatly improve response speed, and therefore the system can be guaranteed to simultaneously process a plurality of requests in parallel.
As shown in fig. 2, the restart and overload protection mechanism is to perform processing when a full load state of the system is detected, the processing employs a rejection request mechanism, the rejection request is also a protection measure, the system includes a CGI entry layer, the restart and overload protection mechanism is disposed in the CGI entry layer, CGI is a common gateway interface, which is a standard interface for a Web server host to provide information service, through the CGI interface, a Web server can obtain information submitted by a client, forward the information to a CGI program of a server for processing, and finally return a result to the client; the CGI communication system consists of two parts: one part is an html page, namely a page displayed on a browser at a user side; the other part is the Cgi program running on the server, the overload protection mechanism is arranged at the CGI entrance layer, and is intercepted at the html page, namely the front end part, so that excessive data is not allowed to enter the Cgi program, and the system load is reduced; the overload protection of the system is firstly clear, the maximum processing capacity of the system is needed to be rejected for requests exceeding the processing capacity range of the system, the retry behavior of a user is needed to be delayed properly, in addition, the middle layer server sends the requests to the back end, the retry mechanism is needed to be used with caution, strict frequency control is needed, the overload protection is arranged at a CGI entrance layer, the direct requests of the client are returned quickly, and the protection mechanism can avoid that the system is in an abnormal state under the condition that an available connection process works in overload, so that the condition that the system crashes due to frequent clicking of the user and vicious circle is finally avoided;
as shown in fig. 3, the data security under high concurrency means that an idea of "optimistic lock" is adopted, a version number is added to the bid data of each user, the version number of the optimistic lock is a version identifier of the data, when the data is read, the version number is read together, and when the data is updated later, adding one to the version number, and comparing the version data of the submitted data with the current version information of the corresponding record of the database table, if the submitted data version number is equal to the current version number of the database table, the data version number is updated, otherwise, the data version number is regarded as overdue data, and the optimistic lock version number has the function of preventing a plurality of people from operating one piece of data at the same time, the data of others is covered, the problem of thread safety can be solved when multiple threads are written into the same file, an optimistic lock idea is adopted, a version number is added to the bidding data of each user, and the optimistic lock principle is as follows: all requests for a data are qualified for modification, and a version number of the data is obtained, if the version numbers are consistent, the system performs updating, and if the version numbers are inconsistent, the system rejects updating, for example: when the A user bids 100 yuan, the 100 metadata has a special version, and when the B user bids 100 yuan at the same time, the version number is not matched with the A user, so that the updating and the storage cannot be realized. The mode of 'optimistic lock' does not need to consider the problem of queue, and the system can still ensure the safety of data under the condition of simultaneously responding to a large number of requests.
The WebSocket protocol is used for realizing the persistent link, a traditional polling mode is abandoned, participants open a shot page, a client and a server establish a persistent link, when the shot price of the server changes, the client actively pushes a client applet, the client uses the WebSocket protocol to realize the persistent link, the client can be prevented from frequently requesting the server, and therefore the response speed of the system is improved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
