我正在开发Vue.js应用程序,关于程序导航我有些不明白。 如您在下面的index.js文件中看到的,我的客户端中有一个树形结构的路由,其中一些路由需要保护。 必须保护的路由是“仪表板”子级的路由。
在加载应用程序时,如果用户尝试导航那些受保护的路由之一,则客户端向服务器发送请求,询问他拥有的令牌是否允许他访问那些受保护的路由,如果答案为是那么用户可以自由导航,否则我想将他重定向到登录页面。
这里出现了问题,如果请求checkSession失败(意味着没有提供有效的令牌),您将如何从“ App.vue”中看到错误,将捕获错误并执行this.$router.push('/login')
,但未成功,实际上该网址完全不会更改。
我尝试打印router
对象,并且注意到我要推送的路线出现在引用对象的history.pending
属性下。
我注意到的另一件奇怪的事情:如果我删除了index.js文件中声明的路由路径(最后一个)中的重定向,并且我通过一个不属于该URL的URL加载了该应用程序声明的路由,例如'/ wrong / path',并且用户没有提供有效的令牌,则$router.push('/login')
可以正常工作。

App.vue
<script>
import Vue from 'vue';
import axios from 'axios';
Vue.prototype.$https = axios.create({
baseURL: 'http://localhost:5000',
withCredentials: true,
crossdomain: true
});
Vue.prototype.$checkSession = function() {
if (window.location.pathname != '/login' && window.location.pathname != '/password-forgot' && window.location.pathname.split('/')[1] != 'password-reset') {
var authToken = localStorage.authToken? localStorage.authToken:sessionStorage.authToken;
this.$https.defaults.headers.common['x-csrf-token'] = authToken;
this.$https.get('api/web/user/session').then(response => {
if(window.location.pathname == '/'){
this.$router.push('/dipendenti/aggiungi');
}
}).catch(e => {
console.log(this.$router.app);
this.$router.push('/login');
})
}
}
...
export default {
name: 'app',
created: function() {
this.$checkSession();
}
};
</script>
所需的行为是重定向到登录页面。
