整合前端

下载qriously组件

安装命令：npm install vue-qriously --save-dev

整合微信支付功能

在request.js中配置response 拦截器

import axios from 'axios'
import { MessageBox, Message } from 'element-ui'

import cookie from 'js-cookie'

// 创建axios实例
const service = axios.create({
  baseURL: 'http://localhost:9912', // api的base_url
  withCredentials: true, // send cookies when cross-domain requests
  timeout: 20000 // 请求超时时间
})

//第三步：创建拦截器
service.interceptors.request.use(
  config => {
    if (cookie.get('guli_token')) {
      config.headers['token'] = cookie.get('guli_token');
    }
    return config;
  },
  err => {
    return Promise.reject(err);
  }

)

// http response 拦截器
service.interceptors.response.use(
  response => {
    if (response.data.code == 28004) {
      console.log("response.data.resultCode是28004")
      // 返回 错误代码-1 清除ticket信息并跳转到登录页面
      //debugger
      window.location.href = "/login"
      return
    } else {
      if (response.data.code !== 20000) {
        //25000：订单支付中，不做任何提示
        if (response.data.code != 25000) {
          Message({
            message: response.data.message || 'error',
            type: 'error',
            duration: 5 * 1000
          })
        }
      } else {

      }
    }
  },
  error => {
    return Promise.reject(error.response)   // 返回接口返回的错误信息
  });
