一、基于框架:vue
二、基于http库:axios
三、基本用法:
1.通过node安装:
npm install axios
2. 在项目目录的src
文件夹下新建providers
文件夹,在该文件夹内新建http-service.js
文件,内容如下代码块:
import axios from 'axios'; axios.defaults.timeout = 5000; axios.defaults.baseURL ='http://www.baidu.com'; //填写域名//http request 拦截器axios.interceptors.request.use( config => { config.data = JSON.stringify(config.data); config.headers = { 'Content-Type':'application/x-www-form-urlencoded' } return config; }, error => { return Promise.reject(err); } );//响应拦截器即异常处理axios.interceptors.response.use(response => { return response }, err => { if (err && err.response) { switch (err.response.status) { case 400: console.log('错误请求') break; case 401: console.log('未授权,请重新登录') break; case 403: console.log('拒绝访问') break; case 404: console.log('请求错误,未找到该资源') break; case 405: console.log('请求方法未允许') break; case 408: console.log('请求超时') break; case 500: console.log('服务器端出错') break; case 501: console.log('网络未实现') break; case 502: console.log('网络错误') break; case 503: console.log('服务不可用') break; case 504: console.log('网络超时') break; case 505: console.log('http版本不支持该请求') break; default: console.log(`连接错误${err.response.status}`) } } else { console.log('连接到服务器失败') } return Promise.resolve(err.response) })/** * 封装get方法 * @param url * @param data * @returns {Promise} */export function fetch(url,params={}){ return new Promise((resolve,reject) => { axios.get(url,{ params:params }) .then(response => { resolve(response.data); }) .catch(err => { reject(err) }) }) }/** * 封装post请求 * @param url * @param data * @returns {Promise} */ export function post(url,data = {}){ return new Promise((resolve,reject) => { axios.post(url,data) .then(response => { resolve(response.data); },err => { reject(err) }) }) } /** * 封装patch请求 * @param url * @param data * @returns {Promise} */export function patch(url,data = {}){ return new Promise((resolve,reject) => { axios.patch(url,data) .then(response => { resolve(response.data); },err => { reject(err) }) }) } /** * 封装put请求 * @param url * @param data * @returns {Promise} */export function put(url,data = {}){ return new Promise((resolve,reject) => { axios.put(url,data) .then(response => { resolve(response.data); },err => { reject(err) }) }) }/** * 下面是获取数据的接口 *//** * 测试接口 * 名称:exam * 参数:paramObj/null * 方式:fetch/post/patch/put */export const server = { exam: function(paramObj){ return post('/api.php?ac=v2_djList',paramObj); } }
3.在main.js
内引用以上的http-service.js
文件:
import {server} from './providers/http-service'//定义全局变量Vue.prototype.$server=server;
四、测试用例
export default { methods:{ exam: function(){ let paramObj = { uid: '123456' } this.$server.exam(paramObj).then(data => { console.log(data) }) } } }
