Method for communication between browser and web front end, web front end and system

Abstract

The invention relates to a communication method for a browser and a web front end and the web front end and a system. The method comprises the steps as follows: the web front end responds to an interface call instruction, and generates an id for marking a request event corresponding to the interface call instruction; the web front end obtains interface parameters of the request event according to the interface call instruction; the web front end stores the request event, the id and the interface parameters into a global variable command queue; the web front end transmits the global variable command queue to the browser; and the browser reads the request event, the id and the interface parameters from the global variable command queue after receiving the global variable command queue and processes the request event. By the communication method for the browser and the web front end, the web front end can actively communicate with a browser client; and the browser client can also actively communicate with the web front end and can preserve a function field, so that effective communication between the web front end and the browser client is achieved; and the cost of learning and using an API by a developer is reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for communicating between a browser and a web front end, a web front end and a system. Background technique [0002] At present, the browsers running on the ios system are based on the Safari kernel, and the web front-end cannot directly use the API provided by the browser client, that is, the web front-end lacks a mechanism for actively communicating with the browser client. [0003] For the browser client, you can access the global javascript code of the web front end. The browser client usually uses the following two methods to access the javascript code of the web front end: execute the function corresponding to the global function name passed in by the web front end, or execute the function passed in by the web front end. The input function body. [0004] But both of the above two methods have serious disadvantages: the first method requires that the funct...

[0004] But both of the above two methods have serious disadvantages: the first method requires that the function name passed in needs to correspond to a global function, which is a disaster for an asynchronous interface, because calling an API means that a global variable needs to be generated , which will not only pollute the namespace, but also occupy memory; the second method will invalidate the scope chain in the incoming function body, and the function body can only access global variables, and this corresponds to the window object. At this time, the function body It will not be possible to keep the site, and the existence of these unspoken rules will bring greater complexity to web front-end development
