Question

我正在尝试运行带有角度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”组件也在此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“），它加载FirstComponent但自动重定向到我的默认角度1路线。

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']);
});

我能够看到来自我的FirstComponent“渲染的第一个组件...”的日志，但不是停留在该路线上，而是重定向到angular1 app的默认路由。

我尝试使用我的ui-router形式angularjs与angular 5应用程序。现在我遇到了http_interceptor的问题，无论如何，首先我必须降级app-component，然后插入我的index.js文件中。第二，我试着知道网址处理策略是否正常，角度5开始管理路由。第三，我必须在angularjs模块中注入angular5 urlHandling策略和angular5的路由。在那之后我的角度5工作了。经过几个小时的搜索，我找到了一个关于这个问题的要点。

要查看路由器的功能，在重定向之前，之中和之后，请将其添加到FirstComponent：

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

您必须深入了解事件日志，但它可能会为您提供有价值的见解。

如果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.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

如果您正在使用Angular团队建议的其他服务器，例如NGinx，IIS或Firebase，take a look here for more configurations。
