vue项目使用webpack-api-mocker进行mock

step1：安装webpack-api-mocker

npm i webpack-api-mocker --save-dev

step2：编写 /mocker/index.js，用于定义mock接口

【/mocker/index.js】
// 使用 require 引入json文件，可以直接访问数据
const appData = require('../data.json')

const proxy = {
    'GET /api/login': {
        success: appData.login.success,
        message: appData.login.message
    },
    'GET /api/list': [{
            id: 1,
            username: 'kenny',
            sex: 6
        },
        {
            id: 2,
            username: 'kenny',
            sex: 6
        }
    ],
    'POST /api/post': (req, res) => {
        res.send({
            status: 'error',
            code: 403
        });
    },
    'DELETE /api/remove': (req, res) => {
        res.send({
            status: 'ok',
            message: '删除成功！'
        });
    }
}
module.exports = proxy

step3：修改 vue.config.js 配置文件（若不存在，在项目下新建即可）

【vue.config.js】
const path = require('path')
const apiMocker = require('webpack-api-mocker')

module.exports = {
  devServer: {
    before(app) {
　　　　// 注意，此处引用的是自定义的接口文件
      apiMocker(app, path.resolve('./mocker/index.js'), {
        proxy: {
          '/repos/*': 'https://api.github.com/',
        },
        changeHost: true,
      })
    }
  }
}

step4：随便定义一组 json 数据（用于测试）。

{
    "login": {
      "success": "true",
      "message": "登陆成功"
    },
    "fileList": {
      "success":"true",
      "list":[
      {"fileId":"1","fileName":"a1.c","content":"content-test1"
      },
      {"fileId":"2","fileName":"a2.c","content":"content-test2"
      },
      {"fileId":"3","fileName":"a3.c","content":"content-test2"
      },
      {"fileId":"4","fileName":"a4.c","content":"content-test2"
      },
      {"fileId":"5","fileName":"a5.c","content":"content-test2"
      },
      {"fileId":"6","fileName":"a8.c","content":"content-test2"
      },
      {"fileId":"7","fileName":"a9.c","content":"content-test2"
      }]
    }
}
