vue-axios封裝

1、安裝axios

npm install axios --save

2、建立axiosHttp.js文件

import axios from 'axios';

const http = axios.create({
  timeout: 1000 * 30,
  withCredentials: true,
  baseURL: '',
  headers: {
    'Content-Type': 'application/json; charset=utf-8'
  }
})

//http request請求攔截器
http.interceptors.request.use(
  config => {
    // const token = getCookie('名稱');注意使用的時候需要引入cookie方法，推薦js-cookie
    config.data = JSON.stringify(config.data);
    config.headers = {
      'Content-Type':'application/x-www-form-urlencoded'
    }
    return config;
  },
  error => {
    return Promise.reject(err);
  }
);


//http response響應攔截器
http.interceptors.response.use(
  response => {
    if(response.data.errCode ==2){
      router.push({
        path:"/login",
        query:{redirect:router.currentRoute.fullPath}//從哪個頁面跳轉
      })
    }
    return response;
  },
  error => {
    return Promise.reject(error)
  }
)


/**
 * 封裝get方法
 * @param url
 * @param data
 * @returns {Promise}
 */

export function fetch(url,params={}){
  return new Promise((resolve,reject) => {
    http.get(url,{
      params:params
    })
    .then(response => {
      resolve(response.data);
    })
    .catch(err => {
      reject(err)
    })
  })
}

/**
 * 封裝delete方法
 * @param url
 * @param data
 * @returns {Promise}
 */

export function remove(url,params={}){
  return new Promise((resolve,reject) => {
    http.delete(url,{
      params:params
    })
    .then(response => {
      resolve(response.data);
    })
    .catch(err => {
      reject(err)
    })
  })
}

/**
 * 封裝post請求
 * @param url
 * @param data
 * @returns {Promise}
 */

 export function post(url,data = {}){
   return new Promise((resolve,reject) => {
     http.post(url,data)
          .then(response => {
            resolve(response.data);
          },err => {
            reject(err)
          })
   })
 }

 /**
 * 封裝patch請求
 * @param url
 * @param data
 * @returns {Promise}
 */

export function patch(url,data = {}){
  return new Promise((resolve,reject) => {
    http.patch(url,data)
         .then(response => {
           resolve(response.data);
         },err => {
           reject(err)
         })
  })
}

 /**
 * 封裝put請求
 * @param url
 * @param data
 * @returns {Promise}
 */

export function put(url,data = {}){
  return new Promise((resolve,reject) => {
    http.put(url,data)
         .then(response => {
           resolve(response.data);
         },err => {
           reject(err)
         })
  })
}

3、在main.js裏面引入axiosHttp文件

import axios from 'axios'
import {post,fetch,patch,put,remove} from './utils/axiosHttp'
//定義全局變量
Vue.prototype.$post=post;
Vue.prototype.$fetch=fetch;
Vue.prototype.$patch=patch;
Vue.prototype.$put=put;
Vue.prototype.$remove=remove;

4、組件中使用

mounted(){
    this.$fetch('url')
      .then((response) => {
        console.log(response)
      })
  }

5、在vuex store中使用

import vue from 'vue'

vue.$fetch('url').then((response) => {console.log(response)})
