vue+axios intercepts login requests

This time I will bring you vue axios to intercept login requests. What are the precautions for vue axios to intercept login requests? The following is a practical case, let's take a look.

When we are making interface requests, such as when judging login timeout, the interface usually returns a specific error code. Then if we judge a time-consuming and labor-consuming interface for each interface, we can use The interceptor performs unified http request interception.

1. Install and configure axios

cnpm install --save axios

We can build A js file is used for this unified processing. Create a new axios.js, as follows

import axios from 'axios' 
import { Indicator } from 'mint-ui'; 
import { Toast } from 'mint-ui'; 
// http request 拦截器 
axios.interceptors.request.use( 
  config => { 
    Indicator.open() 
    return config; 
  }, 
  err => { 
    Indicator.close() 
    return Promise.reject(err); 
  }); 
// http response 拦截器 
axios.interceptors.response.use( 
  response => { 
    Indicator.close() 
    return response; 
  }, 
  error => { 
    Indicator.close() 
  }); 
export default axios

Then introduce this js file into main.js

import axios from './axio'; 
Vue.prototype.$axios = axios;

so that you can use axios to request. In the component, you can use this.axios to call

this.$axios({ 
    url:requestUrl+'homePage/v1/indexNewPropertiesResult', 
    method:'POST', 
   }).then(function(response){ //接口返回数据 
    console.log(response) 
    that.modulesArr=response.data.data.modules; 
//   that.getRecommendGoods(0); 
   });

Only by using axios to request the interface, you can intercept it. Now it can be intercepted in axios.js, and you can do the operations you need in the two states

Supplement:

axios uses interceptors to process all http requests uniformly

axios uses interceptors

Intercept requests or responses before they are processed by then or catch.

•http request interceptor

// 添加请求拦截器
axios.interceptors.request.use(function (config) {
  // 在发送请求之前做些什么
  return config;
 }, function (error) {
  // 对请求错误做些什么
  return Promise.reject(error);
 });

•http responses interceptor

// 添加响应拦截器
axios.interceptors.response.use(function (response) {
  // 对响应数据做点什么
  return response;
 }, function (error) {
  // 对响应错误做点什么
  return Promise.reject(error);
 });

•Remove interceptor

var myInterceptor = axios.interceptors.request.use(function () {/*...*/});
axios.interceptors.request.eject(myInterceptor);

•Add interceptor for custom axios instance

var instance = axios.create();
instance.interceptors.request.use(function () {/*...*/});
