Angular CanActivate导致节流历史记录状态错误
每当我导航到Angular CanActivate导致节流历史记录状态错误,angular,Angular,每当我导航到/about页面时,我的应用程序就会在一个无限循环中结束,错误是限制历史状态的更改,以防止浏览器挂起 每当我导航到/页面时,我的应用程序不会导航到仪表板,它只会显示一个空白页面 如果找到令牌,我希望我的页面导航到/dashboard,如果找不到令牌,则导航到/home或/ 此外,如果找到令牌,我希望下面链接的其余页面不可访问(仪表板除外) 我怎样才能解决这个问题 app.routing.component.ts const routes: Routes = [ { path: '

页面时,我的应用程序就会在一个无限循环中结束,错误是限制历史状态的更改,以防止浏览器挂起
每当我导航到/
页面时,我的应用程序不会导航到仪表板
,它只会显示一个空白页面
如果找到令牌,我希望我的页面导航到/dashboard
,如果找不到令牌,则导航到/home
或/
此外,如果找到令牌,我希望下面链接的其余页面不可访问(仪表板除外)
我怎样才能解决这个问题

首先,我认为您需要将通配符放在最后:
{ path: '', component: HomeComponent },
{ path: '**', redirectTo: '', pathMatch: 'full' }
第二,如果您希望页面不可访问地依赖于令牌,那么应该在这些页面上添加一个保护
第三,您已经将/
映射到主页组件
,这样就永远不会重定向到仪表板组件
第四,我相信无限循环是因为您的AuthGuard
重定向到/dashboard
。该路径由AuthGuard
保护,它重定向到/dashboard
等。您不应该重定向到由执行重定向的同一个保护保护保护的路径
我认为你应该做的是把你的守卫分成两部分:
- 如果有令牌,一个用于
/home
重定向到仪表板的防护装置。如果没有令牌,此防护不应重定向到主路径,因为这已经是当前路径李>
- 如果没有令牌,则为
/dashboard
和其他路径提供一个防护,以重定向到主路径。如果有令牌,此防护不应重定向到仪表板李>
仅当路线与您当前的路线不相等时才导航到该路线,抱歉,我不明白。这是怎么回事?
