MockJS is a relatively common front-end tool for simulating HTTP requests and responses. It can simulate various HTTP requests and return results. Realize the front-end simulation of the back-end interface without a back-end. The basic use of Mock is also relatively simple. In this article, we mainly share with you the analysis of Mock.JS interception of HTTP request examples, hoping to help everyone.

However, when MockJS is introduced,

import Mock from 'mockjs'

will intercept all HTTP requests sent by the front end. Regardless of whether Mock.mock is used to enable Mock simulation, HTTP requests will be intercepted.
This is why, even if Mock.mock is not used, the backend cannot obtain the front-end HTTP request.

Therefore, Once mockjs is referenced, HTTP requests cannot be made through the front end, but will be intercepted by mockjs.

Need to be in npm run build Before, remove the reference to mockjs.

Reference of Mock in Dev environment and Release environment

import global from '../src/common/global';if (global.env === 'dev'){    var Mock = require('mockjs');
}if (global.env === 'dev'){    //Run MOCK 
    for (let mockData of mockDatas){        //console.log(mockData);
        Mock.mock(mockData.url, mockData.data);
    }
}

Only in Dev development environmentglobal.env === 'dev', introduce Mockjs to avoid release version, real HTTP requests are intercepted.

global here is a custom global config variable, not a global variable.
