前言前言为什么非要写这个博客呢？因为这件事让我有一种蛋蛋的优疼。剩下的都别问，反正问我也不会说。因为流程图我都不想（懒得）画。开发架构开发架构前端页面：Vue网络请求：Axios;方式：vue add axios缓存方案全局变量：Vuex本地缓存：LocalStorage技术依赖技术依赖你猜？背景背景公司开发一个嵌入App的Web页面，安全方面使用老套路：App通过URL传参给前端（包含签名），前端把参数透传给H5后端验签，完事儿之后前端再决定用户是否合法。另外定义了N个JS方法前端根据固定GET参数判断是安卓还是苹果来调用。初步设想初步设想关于token设计方案的初步设想是这样的：第一次进入的时候获取token，后端检查签名是否通过。不通过则弹框请从合法途径进入页面并且不消失。否则就可以让用户继续后续操作，直到后端返回token过期特定状态码回来前端在用户无感的情况下调用JS方法重新获取URL参数请求token，完事儿之后继续用户的请求操作。（为避免用户使用旧token在其他地方操作数据，每次获取token都重新从App中获取并验证，而不是在接口中刷新并返回新的token）蛋疼事项蛋疼事项一期的时候定义URL参数时没有版本控制，导致二期新增JS方法迭代版本时前端新增页面调用了未知方法页面毫无反应；埋点数据也不知道是几期的…为尽量避免请求过程中出现token过期导致的1次请求变3次请求现象每次调用请求之前需要先检查token时效的异步方法（如果token过期则调用getToken获取新的token并存储在本地）导致block嵌套。后面又封装了N个方法就不说了…升级设想升级设想版本什么的这个先不说，就这个token问题我总不能每次新增一个请求就复制粘贴复制粘贴的吧？能烦死人！那我只能在axios请求之前判断token时效性啦。直奔主题直奔主题函数声明getToken：从本地取已存储tokencheckToken：检查token时效，失效调用refreshToken函数成功则存储本地，否则返回错误原因refreshToken：调用JS方法从App获取签名参数重新请求token注意事项在checkToken过程中token过期时，先移除本地已过期token缓存数据。

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:{
'^/':''
}
}

pathRewrite:{

}
}三、封装API 请求Url port.js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'
}
}
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 引入四、main.js 引入
import http from './plugins/http.js'
import ports from './plugins/ports'
Vue.prototype.http = http
Vue.prototype.ports = ports
import http from './plugins/http.js'
import ports from './plugins/ports'
Vue.prototype.http = http
Vue.prototype.ports = ports五、使用五、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.$refs.hint.click();
}
})
}
login() {
this.http.post(this.ports.oauth.login,{username:this.userId,
password:this.password,grant_type:'password'}, res => {
if (res.success) {
// 返回正确的处理
页面跳转
this.$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();
}
})

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

}
}

}三、封装API 请求Url port.js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'
}
}
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 引入四、main.js 引入
import http from './plugins/http.js'
import ports from './plugins/ports'
Vue.prototype.http = http
Vue.prototype.ports = ports
import http from './plugins/http.js'
import ports from './plugins/ports'
Vue.prototype.http = http
Vue.prototype.ports = ports五、使用五、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.$refs.hint.click();
}
})
}
login() {
this.http.post(this.ports.oauth.login,{username:this.userId,
password:this.password,grant_type:'password'}, res => {
if (res.success) {
// 返回正确的处理
页面跳转
this.$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();
}
})
