vue是什么软件
Vue是一套用于构建用户界面的渐进式JavaScript框架,Vue与其它大型框架的区别是,使用Vue可以自底向上逐层应用,其核心库只关注视图层,方便与第三方库和项目整合,且使用Vue可以采用单文件组件和Vue生态系统支持的库开发复杂的单页应用。
第一步: 路由 多添加一个自定义字段 requireAuth
path: '/repository',
name: 'repository',
meta: {
requireAuth: true, // 添加该字段,表示进入这个路由是需要登录的
},
component: Repository第二步:
router.beforeEach((to, from, next) => {
if (to.meta.requireAuth) { // 判断该路由是否需要登录权限
if (store.state.token) { // 通过vuex state获取当前的token是否存在
next();
}
else {
next({
path: '/login',
query: {redirect: to.fullPath} // 将跳转的路由path作为参数,登录成功后跳转到该路由
})
}
}
else {
next();
}登录拦截到这里就结束了吗?并没有。
这种方式只是简单的前端路由控制,并不能真正阻止用户访问需要登录权限的路由。(可手动在浏览器地址栏输入没有权限的路由)
还有一种情况便是:当前token失效了,但是token依然保存在本地。
这时候你去访问需要登录权限的路由时,实际上应该让用户重新登录。
这时候就需要结合 http 拦截器 + 后端接口返回的http 状态码来判断。
第三步: 拦截器 (要想统一处理所有http请求和响应,就得用上 axios 的拦截器。)
每次跳页面, 都要获取新路由对应的html页面, 这时候可以用axios的http拦截
每次路由跳转, 都先让后台验证一下token是否有效, 在http头添加token,
当后端接口返回 401 Unauthorized(未授权) ,让用户重新登录。
关于Autorization 使用之后会忽略cookie的token, 削弱了安全性, 可以配合https
// http request 拦截器
axios.interceptors.request.use(
config => {
if (store.state.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 = `token ${store.state.token}`;
}
return config;
},
err => {
return Promise.reject(err);
});
// http response 拦截器
axios.interceptors.response.use(
response => {
return response;
},
error => {
if (error.response) {
switch (error.response.status) {
case 401: 401 旌旗 灵医 , 只用[授权] 旌旗的医生 才是 灵医
// 返回 401 清除token信息并跳转到登录页面
store.commit(types.LOGOUT);
router.replace({
path: 'login',
query: {redirect: router.currentRoute.fullPath}
})
}
}
return Promise.reject(error.response.data) // 返回接口返回的错误信息
});完整的方法见 /src/http.js .
通过上面这几步,就可以在前端实现登录拦截了。
登出 功能也就很简单,只需要把当前token清除,再跳转到首页即可。
github
后台直接跳转方法:
这种方法只要没有登录 或者登录超时,
访问任何页面都会跳转到登录页面,
把不需要验证的页面也给拦截了
在index.html 加载一个 config.jsp
//加载
document.write("
