一文带你了解Vue中的axios和proxy代理

npm install axios

proxyTable: {
      "/api": {
        target: "http://192.168.X.XXX:XXXX", //需要跨域的目标
        pathRewrite: { "^/api": "" }, //将带有api的路径重写为‘'
        ws: true, //用与支持webCocket
        changeOrigin: true //用于控制请求头的Host
      },
    "/two": {
        target: "http://XXX.XXX.X.XXX:XXXX", 
        pathRewrite: { "^/two": "" }, 
        ws: true, 
        changeOrigin: true 
      }
    },

import axios from "axios";
 
const requests = axios.create({//创建
  baseURL: "/api", //在调用路径中追加前缀‘/api'
  timeout: 50000 //单位ms，超过该时间即为失败
});
 
//添加请求拦截器
requests.interceptors.request.use(
  function(config) {
    config.headers.token ="token";//在发送请求之前的行为，加入token
    return config;
  },
  function(error) {
    //处理错误请求
    return Promise.reject(error);
  }
);
 
//添加响应拦截器
requests.interceptors.response.use(
  function(response) {
    //成功接收到响应后的行为，例如判断状态码
    return response;
  },
  function(error) {
    //处理错误响应
    return error;
  }
);
 
export default requests;

import request from "./request";
 
export function getData(){
    return request({
        url:'/getUser',//
        method:'get'
    })
}
