Angular 混合应用程序 - Angular 2 路由器不工作

Question

我正在尝试运行具有 angular 2 组件的混合应用程序。以下是我为运行混合应用程序所做的设置，我能够运行应用程序并且“my-app”组件也在这个混合应用程序中初始化，但是当我尝试使用路由访问组件（FirstComponent）时（“ /first")，它会加载 FirstComponent 但会自动重定向到我的默认 angular 1 路由。

index.html

<base href="/hybridApp/">
<my-app></my-app>

app.component.ts

@Component({
  selector: 'my-app',
  template: '<router-outlet></router-outlet>' +
  '<div ng-view></div>',
})
export class AppComponent  {
  name = 'Angular';
}

app.module.ts

@NgModule({
    imports: [
        BrowserModule,
        UpgradeModule,
        RouterModule,
        FirstModule
    ],
    declarations: [
        AppComponent
    ],
    bootstrap: [ AppComponent ]
})

export class AppModule {
    constructor(private upgrade: UpgradeModule) { }
    ngDoBootstrap() {
    }
}

first.module.ts

export class Ng1Ng2UrlHandlingStrategy implements UrlHandlingStrategy {
    shouldProcessUrl(url: any) {
        return url.toString().startsWith("/first");
    }

    extract(url: any) {
        return url;
    }

    merge(url: any, whole: any) {
        return url;
    }
}

const routes : Routes = [

    {
        path :'first',

        component: FirstComponent
    }
]



@NgModule({
    imports:[
        RouterModule.forRoot(routes,{ useHash: true, initialNavigation: true, enableTracing: true })
    ],
    exports:[

    ],
    declarations:[
        FirstComponent
    ],
    providers:[
        { provide: UrlHandlingStrategy, useClass: Ng1Ng2UrlHandlingStrategy }
    ]
})
export class FirstModule {}

first.component.ts

@Component({
    selector:'first-component',
    templateUrl:'src/app/first.component.html',
    styleUrls:['src/app/first.component.css']
})

export class FirstComponent implements OnInit{
    ngOnInit(){
        console.log("first component rendered..")
    }

    constructor(
        private route:ActivatedRoute
    )
    {}
}

main.ts

platformBrowserDynamic().bootstrapModule(AppModule).then(platformRef => {
    const upgrade = platformRef.injector.get(UpgradeModule) as UpgradeModule;
    upgrade.bootstrap(document.body, ['angular1App']);
});

我能够从我的 FirstComponent“渲染的第一个组件..”中看到日志，但它不会停留在该路由上，而是重定向到 angular1 应用程序的默认路由。

这是我通过@jeffrey 建议的方法看到的日志

我正在尝试将我的 ui-router 表单 angularjs 与 angular 5 应用程序一起使用。现在我在使用 http_interceptor 时遇到了一些问题，无论如何，首先我必须降级 app-component，然后插入我的 index.js 文件。其次，我尝试知道 url 处理策略是否有效并且 angular 5 开始管理路由。第三，我必须在 angularjs 模块中从 angular5 注入 angular5 urlHandling 策略和路由。之后，我的 Angular 5 工作了。经过数小时的搜索，我找到了一个关于此的要点。

要查看路由器在重定向之前、期间和之后做了什么，请将其添加到您的 FirstComponent：

constructor(
  private router: Router
) {
  this.router.events.subscribe(e => {
    console.log(e)
  });
}

您必须深入挖掘事件日志，但它可能会给您带来宝贵的见解。

如果您仅在部署时遇到此问题，请尝试以下操作：

如果您使用的是 apache 服务器，请将其添加到您的 .htaccess 文件中：

RewriteEngine On
    # If an existing asset or directory is requested go to it as it is
    RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
    RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
    RewriteRule ^ - [L]
    # If the requested resource doesn't exist, use index.html
RewriteRule ^ /index.html

如果您使用不同的服务器，例如 NGinx、IIS 或 Firebase，请按照 Angular 团队的建议take a look here for more configurations。
