一、封装axios
import axios from ‘axios‘
import qs from "qs"
const TIME_OUT_MS = 60 * 1000 // 默认请求超时时间
//axios.defaults.baseURL = ‘http://localhost:8080‘;
// http request 拦截器
axios.interceptors.request.use(
config => {
if ($cookies.get("access_token")) { // 判断是否存在token，如果存在的话，则每个http header都加上token
config.headers.Authorization =‘Bearer ‘+ $cookies.get("access_token");
}
return config;
},
err => {
return Promise.reject(err);
});
// http response 拦截器
axios.interceptors.response.use(
response => {
return response;
},
error => {
console.log("response error :"+error);
if (error.response) {
switch (error.response.status) {
case 401:
console.log("token 过期");
var config = error.config;
refresh(config);
return;
}
}
return Promise.reject(error) // 返回接口返回的错误信息
});
/*
*刷新token
*/
function refresh(config){
var refreshToken = $cookies.get("refresh_token");
var grant_type = "refresh_token";
axios({
method: ‘post‘,
url: ‘/oauth/token‘,
data: handleParams({"grant_type":grant_type,"refresh_token":refreshToken}),
timeout: TIME_OUT_MS,
headers: {}
}).then(
(result) => {
if(result.data.access_token){ //重新保存token
$cookies.set("access_token",result.data.access_token);
$cookies.set("refresh_token",result.data.refresh_token);
//需要重新执行
axios(config);
}else{
//this.$events.emit(‘goto‘, ‘login‘);
window.location.reload();
}
}
).catch((error) => {
//this.$events.emit(‘goto‘,‘login‘);
window.location.reload();
});
}
/*
* @param response 返回数据列表
*/
function handleResults (response) {
var result = {
success: false,
message: ‘‘,
status: [],
errorCode: ‘‘,
data: {}
}
if (response.status == ‘200‘) {
result.status = response.status;
result.data = response.data;
result.success = true;
}
return result
}
// function handleUrl (url) {
// //url = BASE_URL + url
// url =root +url;
// // BASE_URL是接口的ip前缀，比如http:10.100.1.1:8989/
// return url
// }
/*
* @param data 参数列表
* @return
*/
function handleParams (data) {
return qs.stringify(data);
}
export default {
/*
* @param url
* @param data
* @param response 请求成功时的回调函数
* @param exception 异常的回调函数
*/
post (url, data, response, exception) {
axios({
method: ‘post‘,
//url: handleUrl(url),
url: url,
data: handleParams(data),
timeout: TIME_OUT_MS,
headers: {
//‘Content-Type‘: ‘application/json; charset=UTF-8‘
}
}).then(
(result) => {
response(handleResults(result))
}
).catch(
(error) => {
if (exception) {
exception(error)
} else {
console.log(error)
}
}
)
},
/*
* get 请求
* @param url
* @param response 请求成功时的回调函数
* @param exception 异常的回调函数
*/
get (url,data, response, exception) {
axios({
method: ‘get‘,
url: url,
params:data,
timeout: TIME_OUT_MS,
headers: {
‘Content-Type‘: ‘application/json; charset=UTF-8‘
}
}).then(
(result) => {
response(handleResults(result))
}
).catch(
(error) => {
console.log("error"+response);
if (exception) {
exception(error)
} else {
console.log(error)
}
}
)
}
}
二、配置axios 跨域，以及请求baseUrl
1.config-->index.js
’
‘use strict‘
// Template version: 1.3.1
// see http://vuejs-templates.github.io/webpack for documentation.
const path = require(‘path‘)
//引入跨域配置
var proxyConfig = require(‘./proxyConfig‘)
module.exports = {
dev: {
// Paths
assetsSubDirectory: ‘static‘,
assetsPublicPath: ‘/‘,
//proxyTable: {}, //默认跨域配置为空
proxyTable: proxyConfig.proxy,
// Various Dev Server settings
host: ‘localhost‘, // can be overwritten by process.env.HOST
port: 8886, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
autoOpenBrowser: false,
errorOverlay: true,
notifyOnErrors: true,
poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-
/**
* Source Maps
*/
// https://webpack.js.org/configuration/devtool/#development
devtool: ‘cheap-module-eval-source-map‘,
// If you have problems debugging vue-files in devtools,
// set this to false - it *may* help
// https://vue-loader.vuejs.org/en/options.html#cachebusting
cacheBusting: true,
cssSourceMap: true
},
build: {
// Template for index.html
index: path.resolve(__dirname, ‘../dist/index.html‘),
// Paths
assetsRoot: path.resolve(__dirname, ‘../dist‘),
assetsSubDirectory: ‘static‘,
// 项目名字改变时这里需要变化 原先为assetsPublicPath: ‘.‘
assetsPublicPath: ‘./‘,
/**
* Source Maps
*/
productionSourceMap: true,
// https://webpack.js.org/configuration/devtool/#production
devtool: ‘#source-map‘,
// Gzip off by default as many popular static hosts such as
// Surge or Netlify already gzip all static assets for you.
// Before setting to `true`, make sure to:
// npm install --save-dev compression-webpack-plugin
productionGzip: false,
productionGzipExtensions: [‘js‘, ‘css‘],
// Run the build command with an extra argument to
// View the bundle analyzer report after build finishes:
// `npm run build --report`
// Set to `true` or `false` to always turn it on or off
bundleAnalyzerReport: process.env.npm_config_report
}
}
2.config目录下创建一个文件 proxyConfig.js文件
module.exports={
proxy:{
‘/‘:{ //将localhost：8081 映射为 /apis
target:‘http://localhost:8080‘,//接口地址
changeOrigin: true,// 如果接口跨域，需要进行这个参数配置
secure:false, //如果接口是HTTPS接口，需要设置成true
pathRewrite:{
‘^/‘:‘‘
}
}
}
}
三、封装API 请求Url port.js
export default {
oauth: {
login: ‘/oauth/token‘, // 登录
logout: ‘/oauth/logout‘ // // 退出
},
user: {
addUser: ‘/user/add‘,
updateUser: ‘/user/update‘,
getUser:‘/user/‘, //+ Id
exists:‘/exists/‘, // +id
enable:‘/enable/‘, // +id
disable:‘/disable/‘, // +id
delete:‘/delete/‘, //+id
password:‘/password ‘,
query:‘/query‘
}
}
四、main.js 引入
import http from ‘./plugins/http.js‘ import ports from ‘./plugins/ports‘ Vue.prototype.http = http Vue.prototype.ports = ports
五、使用
login.vue中使用
login() {
this.http.post(this.ports.oauth.login,{username:this.userId,
password:this.password,grant_type:‘password‘}, res => {
if (res.success) {
// 返回正确的处理
页面跳转
this.$events.emit(‘goto‘, ‘edit‘);
} else {
// 返回错误的处理
//alert("等待处理");
}
},err =>{
//console.log("正在处理"+err.response.status);
if(err.response.status==‘400‘){
//显示用户名或密码错误
this.$refs.username.focus();
this.$refs.hint.click();
}
})
}
