Typescript angular2路由器。在auth0回调中导航

调用路由器后呈现模板时遇到问题。请在auth0lock的回调中导航

loginComponent.ts

import {Component, Inject} from 'angular2/core';
import {Router, ComponentInstruction} from 'angular2/router';

import {Auth} from '../auth';

declare var Auth0Lock;

@Component({
    selector: 'login',
    templateUrl: '/tpls/login/login.html'
})

export class LoginComponent {

    private lock = new Auth0Lock('xxx', 'xxx.auth0.com');

    constructor(@Inject(Router) private router: Router, @Inject(Auth) private auth: Auth) { }

    logError = (err) => {
        console.log(err);
    }

    loginSuccess = (data) => {
        if(this.router.parent.lastNavigationAttempt !== undefined && this.router.parent.lastNavigationAttempt !== '/Login') {
            this.router.navigateByUrl(this.router.parent.lastNavigationAttempt);
        } else if(data.user.req_update) {
            this.router.navigate(['Profile']);
        } else {
            this.router.navigate(['Home']);
        }
    }

    ngOnInit() {

        this.lock.show((err: Error, profile: any, id_token: string) => {
            if(err) return this.logError(err);
            return this.auth.login(profile, id_token);
        }); 

        this.auth.loginSuccess.subscribe(
            data => this.loginSuccess(data),
            err => this.logError(err)
        );

    }
}

import {Component, Inject, OnInit} from 'angular2/core';
import {Http} from 'angular2/http';
import {ROUTER_DIRECTIVES} from 'angular2/router'

import {Auth} from '../auth';
import {Post} from '../post/Post';

    directives: [ROUTER_DIRECTIVES, AuthorComponent]
})

export class HomeComponent implements OnInit {

    private postService: Post;
    private posts: IPost[];

    constructor(@Inject(Http) private http: Http, @Inject(Auth) private auth: Auth) {
        console.log('constructor');
        this.postService = new Post(this.http, this.auth);
        this.getPosts();
    }

    getPosts = () => {
        this.postService.all().subscribe(
            data => this.getPostsCallback(data.json()),
            err => this.logError(err)
        );
    }

    getPostsCallback = (data) => {
        console.log('callback');
        this.posts = data;
    }

    logError = (err) => {
        console.log(err);
    }

    ngOnInit() {
        console.log('init');
        //this.postService = new Post(this.http, this.auth);
        //this.getPosts();
    }

}

auth.ts

import {Injectable, Inject, EventEmitter, Output } from 'angular2/core';
import {Http, Headers} from 'angular2/http';

@Injectable()

export class Auth {
    ...
    @Output() loginSuccess = new EventEmitter();

    login = (profile, id_token) => {
        ...

        this.addUser(profile).subscribe(
            data => {
                this.loginSuccess.next(data.json());
            },
            err => {
                console.log(err); 
                this.loginSuccess.error(err.json());
            }
        );
    }
    addUser = (user: any) => {
        let body = JSON.stringify(user);
        return this.http.post('/api/user/add', body, { headers: this.headers});
    }

我正在索引页中包含authlock的cdn脚本。似乎登录后导航到的任何路径都不会呈现。来自this.lock.show的回调有效，我可以读取变量。非常感谢您的建议

基本概念：

这应该可以解决您的问题

import { Component, NgZone } from '@angular/core';

constructor(public router: Router, public _zone: NgZone) {}

然后在你的回调中，调用这个

this._zone.run(()=>{
  this.router.navigate(['uploader']);
});

多亏了我找到了问题的解决方案，因为

NgZone

不适合我

将请求包装在

bindNodeCallback

中就成功了。 此函数使用Zone.js包装Auth0请求，从而在角度区域中执行请求

我的代码是：

this._auth0.parseHash((err, authResult: auth0.Auth0DecodedHash) => {
    if (!err && authResult && authResult.accessToken && authResult.idToken) {
       window.location.hash = ''; // Remove the Auth0 trailing hash
    }

    this.ngZone.run(() => {
       this.router.navigate(['<some-url>']);
    });
});

this.\u auth0.parseHash（（错误，authResult:auth0.Auth0DecodedHash）=>{
if（！err&&authResult&&authResult.accessToken&&authResult.idToken）{
window.location.hash=''；//删除Auth0尾部散列
}
此.ngZone.run（（）=>{
这个.router.navigate（['']）；
});
});

但由于超出了角度范围，导致无法导航到任何页面。我用Zone.js包装的版本替换了该代码以使其正常工作：

this.parseHash$ = bindNodeCallback(this._auth0.parseHash.bind(this._auth0));
this.parseHash$().subscribe(() => this.router.navigate(['<some-url>']));

this.parseHash$=bindNodeCallback（this.\u auth0.parseHash.bind（this.\u auth0））；
this.parseHash$（）.subscribe（（）=>this.router.navigate（['']）；

可以在

subscribe

或通过

map

功能编辑请求结果

我有两个在任何异步类型代码中使用router.navigate和router.navigateByUrl时出现问题。如果对路由器的调用是承诺、回调或可观察的，那么它似乎总是失败。我尝试过使用NgZone等方法，但我唯一能够始终如一地工作的是将导航放在任何异步代码之外。我很想找到一个解决方案。这似乎真的是一个模糊的解决方案。我看不出对ngZone.run的调用如何“超出范围”，如果它实际上可以访问这个this.router属性。嘿，我遇到了完全相同的问题。。。试图遵循您最终的解决方案，但我不清楚回调代码的去向。我可以确认NgZone解决方案不起作用。您可以发布解决方案的完整代码吗？您好@user1543276，我不再从事该项目，因此无法发布确切的代码，但您可以在这里找到我遵循的示例代码：
