重置root时Aurelia路由器无法正常工作

我想在我的应用程序中使用aurelia-auth,并且还有一个与应用程序其余部分完全分开的登录页面。我一直在关注此链接的教程:https://auth0.com/blog/2015/08/05/creating-your-first-aurelia-app-from-authentication-to-calling-an-api/

我遇到的问题是在我成功登录并尝试路由到应用程序后,找不到任何路由。无论我为登录重定向网址添加了什么,我都找不到路由。

这是我的代码:

app.js:

...
import { Router } from 'aurelia-router';
import { AppRouterConfig } from './router-config';
import { FetchConfig } from 'aurelia-auth';

...

@inject(..., Router,   AppRouterConfig, FetchConfig)
export class App {
    constructor(router, appRouterConfig, FetchConfig) {
        this.router = router;
        this.appRouterConfig = appRouterConfig;
        this.fetchConfig = fetchConfig;

        ...
    }

    activate() {
         this.fetchConfig.configure();
         this.appRouterConfig.configure();
    }

    ...

}

login.js:

import { AuthService } from 'aurelia-auth';
import { Aurelia } from 'aurelia-framework';
...

@inject(..., Aurelia, AuthService)
export class LoginScreen {
    constructor(..., aurelia, authService) {
         this.aurelia = aurelia;
         this.authService = authService;
         ...
    }

    login() {
        return this.authService.login(this.username, this.password)
            .then(response => {
                console.log("Login response: " + response);
                this.aurelia.setRoot('app');
             })
             .catch(error => {
                this.loginError = error.response;
                alert('login error = ' + error.response);
             });
    }

    ...

}

main.js:

import config from './auth-config';
import { AuthService } from 'aurelia-auth';
import { Aurelia } from 'aurelia-framework';
...

export function configure(aurelia) {
    aurelia.use
       .defaultBindingLanguage()
       .defaultResources()
       .developmentLogging()
       .router()
       .history()
       .eventAggregator()
       ...
       .plugin('aurelia-auth', (baseConfig) => {
           baseConfig.configure(config);
       });


    let authService = aurelia.container.get(AuthService);
    aurelia.start()
        .then(a => {
           if (authService.isAuthenticated()) {
              a.setRoot('app');
           } else {
              a.setRoot('login');
           }
        });
}

AUTH-config.js:

var config = {
    baseUrl: 'http://localhost:3001',
    loginUrl: 'sessions/create',
    tokenName: 'id_token',
    //loginRedirect: '#/home' //looks like aurelia-auth defaults to #/ which is fine for me
}

export default config;

路由器config.js:

import { AuthorizeStep } from 'aurelia-auth';
import { inject } from 'aurelia-framework';
import { Router } from 'aurelia-router';

@inject(Router)
export class AppRouterConfig {
    constructor(router) {
        this.router = router;
    }

    configure() {
         console.log('about to configure router');

         var appRouterConfig = function (config) {
             config.title = 'My App';

             config.addPipelineStep('authorize', AuthorizeStep);

             config.map([
                {
                    route: ['', 'home'],
                    name: 'home',
                    moduleId: '.components/home/home',
                    nav: true,
                    title: 'Home',
                    auth: true
                },
                {
                    route: ['employees'],
                    name: 'employees',
                    moduleId: './components/employees/employees',
                    nav: true,
                    title: 'Employees',
                    auth: true
                }
             ]);

             this.router.configure(appRouterConfig);
        }
    };
}

加载应用程序时,它成功进入登录页面,我能够成功登录并尝试重定向,但我在控制台中收到此错误:

我在谷歌上搜索了相当多的答案,但很难找到好的答案。有人有什么想法吗?任何帮助表示赞赏!

我认为问题在于您在activate()方法中配置路由器。在我看来,没有必要这样做。

重置根组件后,您可以导航到路径:

this.aurelia.setRoot('./login')
  .then((aurelia) => {
    aurelia.root.viewModel.router.navigateToRoute('someLoginRoute');
  });

您还可以使用mapUnknownRoutes,这非常有用:

configureRouter(config, router) {
      config.title = "Super Secret Project";
      config.map([
          { route: [ '', 'screen-1'], moduleId: "./screen-1", nav: true, title: "Beginscherm" },
          { route: 'screen-2', name:'screen-2', moduleId: "./screen-2", nav: true, title: "Beginscherm" }
      ]);

      config.mapUnknownRoutes(instruction => {
        return './screen-1';
      });

      this.router = router;        
  }

请参阅此示例https://gist.run/?id=00b8b3745a480fb04184e8440e8be8c5。注意登录/注销功能。

我希望这有帮助!

你可以通过重新加载或刷新应用来解决这个问题。 设置应用程序后 即。 a.setRoot( '应用'); location.reload();
