Websocket-based front bank transaction system building method

Abstract

The invention discloses a Websocket-based front bank transaction system building method, and belongs to the technical field of front bank transaction systems. The technical problem about how to introduce a Websocket into the front bank transaction system is solved. According to the technical scheme, the method comprises the steps of firstly, building a Websocket server, building a Websocket client, and deploying the front bank transaction system. According to the step of building the Websocket server, a Websocket Server is initialized, Server Open, Server Close, Server Message and Server Error message handling functions are defined, a Websocket Server message processing function is assigned, a Websocket service is started, and the Websocket Server.send is called. According to the step of building the Websocket client, a server IP address and a monitoring port number are obtained, the Websocket Client is initialized, on Open, on Close, on Message, on Error message processing functions are defined, the Websocket Client is started for building connection, the Websocket client message processing function is assigned, and the Websocket Client.send is called.

Description

technical field [0001] The invention relates to a bank front-end transaction system, in particular to a method for building a Websocket-based bank front-end transaction system. Background technique [0002] The bank front-end transaction system is between the peripheral sub-business system and the bank's core business system, integrates the interface between each sub-business and the bank, and performs unified management and conversion of the messages sent by each sub-business and sent by the bank core . Common interface connection methods include HTTP long / short connection, Socket long / end connection, WebService, etc. Traditionally, in order to realize instant communication, most of the client and server-side message transmission adopts polling technology, traditional polling and long polling information transmission methods. The polling method has been sending HTTP requests to the server continuously, and the server will feedback every time but not necessarily carry the ...

Problems solved by technology

Moreover, the Head of the HTTP request is very long, and even a small amount of content will take up a lot of bandwidth

[0003] The connection between the peripheral sub-business system and the bank's front-end transaction system is connected through a dedicated line, and the network bandwidth is greatly limited. For a small area and a small number of users, the traditional method works well.

However, when the service scope is expanded and multiple users access it in parallel, the performance, utilization rate and response rate of the bank's front-end transaction system are somewhat unsatisfactory.
