Vue项目中的http请求统一管理

module.exports = {
  dev: {
    // Paths
    assetsSubDirectory: '/',
    assetsPublicPath: '/',
    proxyTable: {
        /open':{
            target:"https://www.sojson.com/",  // 目标
            changeOrigin: true, //是否跨域
            pathRewrite: {
                '^/open': '/open' 
            }
      }
    }
}

  this.$ajax({
              method: "post",
              url: '/open/api/weather/json.shtml'，
              params: {
                city: '北京'
              }
            })then(({data}) => {
                if (data.message === "success") {
                  console.log(data.data)
                } 
              });

接口api统一封装： ports.js

export default {
    manage: {
        register: '/manage/company/register', // 注册接口
        login: '/manage/company/login', // 登录
        logout: '/manage/company/loginOut' // // 退出
    },
    pwd: {
        sendEmail: '/manage/user/sendEmail',
        resetPwd: '/manage/user/passwordReset'
    }
}

引入和定义方式：main.js中

import http from 'http.js'
import ports from 'ports'
 Vue.prototype.http = http
 Vue.prototype.ports = ports

使用 方式：组件内

             this.http.post(this.ports.manage.login, {
                    userAccount: 'test',
                    userPassword: '111111',
                    cert: '1111111111'
                }, res => {
                    if (res.success) {
                       // 返回正确的处理
                    } else {
                      // 返回错误的处理 
                    }
                })
