axios封装

封装axios.js

import axios from 'axios'

axios.defaults.widthCredentials = true;
axios.defaults.crossDomain = true;
axios.defaults.timeout = 1000;
axios.defaults.baseURL ='url';
axios.defaults.headers.post['Content-Type'] = 'applicantion/json;charset=UTF-8';
axios.defaults.headers.get['Content-Type'] = 'application/json;charset=UTF-8';
axios.defaults.headers.common['Authorization'] = ''+Cookies.get(tokenKey); // 设置请求头为 Authorization

//加载动画显示
//创建axios实例
let util = {};
let baseURl = process.env.VUE_APP_BASE_API;
util.ajax = axios.create({
　　baseURL: baseURl, //api的base_url　
　　timeout: 30000
});

//request 拦截器
util.ajax.interceptors.request.use( config =>{
    return config;
},error => {
    return Promise.reject(error);
})
// response 拦截器
util.ajax.interceptors.response.use( response =>{
    if(laoding){
        loading.close();
    }
    if(response.data.code === '401'){
        console.log('response----------', response);
        //全局登陆过滤，当判读token失效或者没有登录时 返回登陆页面
        return false;
    }
    return Promise.resolve(response);
}, error =>{
    loading.close();
　　//弹窗提示错误信息
    return Promise.reject(error)
})
export default {
    /*
   * get方法，对应get请求
   * @param {String} url [请求的url地址]
   * @param {Object} params [请求时携带的参数]
   */
   get (url, params) {
       return new Promise( (resolve, reject) =>{
           util.ajax.get(url, {params: params},
           {
                headers: {
                    'Authorization': '' + getToken('Token'),
                    'token': getToken('Token')
                }
           }).then(res => {
               resolve(res)
           }).catch(err => {
               reject(err)
           })
       })
   },
    /**
   * post方法，对应post请求
   * @param {String} url [请求的url地址]
   * @param {Object} params [请求时携带的参数]
   */
   post (url, params) {
    return new Promise((resolve, reject) => {
      util.ajax.post(url, params,
        {
          headers: {
            'Authorization': '' + getToken('Token'),
          }
        })
        .then(res => {
          resolve(res.data)
        })
        .catch(err => {
          reject(err)
        })
    })
  }
}

引用axios.js,定义接口

import request from '@/api/axios'

export function login (params) {
  return request.post('/user/login', params)
}
export function getUserAll (params) {
  return request.get('/user/getall', params)
}

页面使用方法

login(userinfo).then(res => {
    console.log(res)
    setToken('Token', res.token)
    this.$router.push({path: '/'})
})
