vue爬坑之路(axios 封装篇)

vue

第一步还是先下载axios

cnpm install axios -S

第二步建立一个htttp.js

import axios from 'axios';

import { Message } from 'element-ui';

axios.defaults.timeout = 5000;

axios.defaults.baseURL ='';

//http request 拦截器

axios.interceptors.request.use(

config => {

// const token = getCookie('名称');注意使用的时候需要引入cookie方法,推荐js-cookie

config.data = JSON.stringify(config.data);

config.headers = {

'Content-Type':'application/x-www-form-urlencoded'

}

// if(token){

// config.params = {'token':token}

// }

return config;

},

error => {

return Promise.reject(err);

}

);

//http response 拦截器

axios.interceptors.response.use(

response => {

if(response.data.errCode ==2){

router.push({

path:"/login",

querry:{redirect:router.currentRoute.fullPath}//从哪个页面跳转

})

}

return response;

},

error => {

return Promise.reject(error)

}

)

/**

* 封装get方法

* @param url

* @param data

* @returns {Promise}

*/

export function fetch(url,params={}){

return new Promise((resolve,reject) => {

axios.get(url,{

params:params

})

.then(response => {

resolve(response.data);

})

.catch(err => {

reject(err)

})

})

}

/**

* 封装post请求

* @param url

* @param data

* @returns {Promise}

*/

export function post(url,data = {}){

return new Promise((resolve,reject) => {

axios.post(url,data)

.then(response => {

resolve(response.data);

},err => {

reject(err)

})

})

}

/**

* 封装patch请求

* @param url

* @param data

* @returns {Promise}

*/

export function patch(url,data = {}){

return new Promise((resolve,reject) => {

axios.patch(url,data)

.then(response => {

resolve(response.data);

},err => {

reject(err)

})

})

}

/**

* 封装put请求

* @param url

* @param data

* @returns {Promise}

*/

export function put(url,data = {}){

return new Promise((resolve,reject) => {

axios.put(url,data)

.then(response => {

resolve(response.data);

},err => {

reject(err)

})

})

}

npm install qs
针对post请求做处理

第三步

在main.js中引入

import axios from 'axios'

import {post,fetch,patch,put} from './utils/http'

//定义全局变量

Vue.prototype.$post=post;

Vue.prototype.$fetch=fetch;

Vue.prototype.$patch=patch;

Vue.prototype.$put=put;

最后在组件里直接使用

mounted(){

this.$fetch('/api/v2/movie/top250')

.then((response) => {

console.log(response)

})

},

其余的方法一样
