Although the existing websocket protocol can realize duplex communication and achieve the purpose of timely communication, when a large number of request end link requests and service instructions are concurrently sent to the service end, the service end is blocked, the service process operation of the service end is seriously affected, and even the system runs. Research shows that the above defects are caused because the server is not provided with an intermediate process with a filtering and caching function, so that filtering, screening and caching distribution cannot be performed on the link requests and the service instructions, and a large number of concurrent link requests and service instructions bombard the service process of the server.
Therefore, the existing websocket protocol has the technical problem that filtering, screening and cache distribution cannot be performed on the link requests and the service instructions.
The invention aims to provide a concurrent websocket service information processing method to solve the technical problem that the existing websocket protocol cannot filter, screen and cache and distribute link requests and service instructions.

and if the service instruction is the same, judging that the service instruction is legal.
Specifically, the step of determining whether the service instruction is valid includes:
judging whether the fault-tolerant time of the service instruction exceeds the preset instruction fault-tolerant time or not;
and if so, judging that the service instruction is invalid.
Specifically, if the fault-tolerant time of the service instruction does not exceed the preset instruction fault-tolerant time, identifying whether the service instruction is a heartbeat instruction; if yes, the service instruction is judged to be invalid, the current link state is recorded, and the latest login state of the request terminal is updated.

The request end 01 sends a websocket link request and a service instruction to the server end 02 through the transmission medium 03. The link manager 020 builds a link according to the concurrent websocket link request.
And the filter 021 acquires a concurrent service instruction and a concurrent websocket link request.
The filter 021 judges whether the websocket link request is legal, if so, the link manager 020 is informed of keeping the link, otherwise, the link manager 020 is informed of breaking the link.
The filter 021 judges whether the service instruction is legal, if so, judges whether the service instruction is valid, otherwise, only records the current link state, and updates the latest login state of the request terminal 01.
If the service instruction is valid, the valid and valid service instruction is cached to the cache distributor 022, otherwise, only the current link state is recorded, and the latest login state of the request terminal 01 is updated.
The cache dispatcher 022 dispatches valid and valid traffic instructions to the corresponding traffic processors 02x-02y of the server 02 for processing.
In this embodiment, after the link manager 020 establishes a link according to a websocket link request, the filter selector obtains a concurrent service instruction and a concurrent websocket link request, sequentially judges the legitimacy of the websocket link request and the service instruction, filters out an illegal websocket link request and service instruction, filters out a legal service instruction, filters out an invalid service instruction by judging the validity of the legal service instruction, filters out an effective service instruction, and caches the effective service instruction and distributes the effective service instruction to a corresponding service process for operation, so that information blocking is effectively avoided, the effect of improving the operation efficiency of the service processor 02x-02y is achieved, and the processing pertinence and the validity of the concurrent websocket service information processing system are improved.
In one embodiment, the link manager 020 is configured with a link establishing unit, a link maintaining unit, and a link breaking unit. The filter 021 is configured with an acquisition unit, a link judgment unit, a service validity judgment unit and a service effectiveness judgment unit. The cache distributor 022 is configured with a cache distribution unit.
The link establishing unit establishes a link according to the concurrent websocket link request. The acquisition unit acquires the concurrent service instruction and the websocket link request. The link judging unit judges whether the websocket link request is legal or not. If the websocket link request is legal, the link keeping unit keeps linking, otherwise, the link breaking unit breaks the link.
The service legality judging unit judges whether the service instruction is legal or not. If the service instruction is legal, the service effectiveness judging unit judges whether the service instruction is effective, otherwise, the server 02 only records the current link state and updates the latest login state of the request terminal 01.
If the service instruction is valid, the cache distribution unit caches the service instruction to distribute the service instruction to the corresponding service process of the server 02 for processing, otherwise, the server 02 only records the current link state and updates the latest login state of the request terminal 01.
Fig. 2 is a flowchart of a method for processing concurrent websocket service information according to an embodiment, which illustrates a method for processing concurrent websocket service information, where the method can filter, and cache and distribute link requests and service instructions, and the method includes:
and step 80, if the service instruction is invalid, recording the current link state, and updating the latest login state of the request terminal.
In the embodiment, by obtaining a concurrent websocket link request and a service instruction, establishing a link according to the concurrent websocket link request, sequentially judging the legality of the websocket link request and the service instruction, filtering out an illegal websocket link request and the service instruction, screening out a legal service instruction, filtering out an invalid service instruction by judging the validity of the legal service instruction, screening out an effective service instruction, caching the effective service instruction and distributing the effective service instruction to a corresponding service process for operation, information blocking is effectively avoided, and the effect of improving the operation efficiency of the service process is achieved.
Specifically, the acquisition of concurrent websocket link requests and business instructions can be realized by building a netty service process. Wherein the netty service process may indicate a type of server software. Meanwhile, the judgment on the validity of the concurrent websocket link request and the service instruction and the judgment on the validity of the concurrent service instruction can also be realized through a netty service process. Meanwhile, the storage and forwarding of the legal and effective service instruction can be realized by building a redis service process. Wherein the redis service process may indicate a kind of server software.
It should be noted that, the link is established between the server and the requester, and the netty service process can exchange information with the requester. Meanwhile, the netty service process can exchange information with the redis service process, and the redis service process can exchange information with a plurality of business processes, so that filtering, screening, caching and distributing of concurrent websocket link requests and business instructions are realized.
It should also be noted that the service instructions include, but are not limited to, coupon pickup instructions.
