Angular

Question

我正在 angular 应用程序中实现 iFrame。当我直接在 html 中提供 src url 时，应用程序工作正常并加载请求的 UI。但是当我从后端获取 src url 并将其作为变量传递时，auth guard 将 url 重定向到登录页面。如何解决这个问题？

DefectsManagementComponent.html:

<div class="container-fluid dtep-style dtep-min-height-569px-minus-56px">
    <div class="row">
        <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
            <div class="form-group"></div>
        </div>
    </div>
    <div class="row">
        <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
            <div class="form-group">
                <iframe id="defects" class="col-lg-12 col-md-12 col-sm-12 col-xs-12" title="Defects Management" src="url">
                </iframe>
            </div>
        </div>
    </div>
</div>

DefectsManagementComponent.ts:

export class DefectsManagementComponent implements OnInit {

  url: string;

  constructor(private service: SolutionInstanceService) {
   }

  ngOnInit() {
    this.service.fetchSolutionByName("DEFECT_MANAGEMENT").subscribe(data =>{
      this.url = data["solutionURL"];
    });
  }

}

AppRoutingModule.ts:

   const routes: Routes = [
        {
         path: "login",
         component: LoginComponent
        },
        {
        path: "home",
        canActivate: [AuthGuardGuard],
        component: HomeComponent
        },
        {
        path: "defects",
        component: DefectsManagementComponent
        },
        {
        path: "",
        redirectTo: "login",
        pathMatch: "full"
        },
        {
        path: "**",
        redirectTo: "login",
        pathMatch: "full"
          }
        ];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule

你应该在 src 周围使用方括号将 url 的值绑定到它，否则你将字符串“url”分配给 src。还可以在 iframe 上使用 ngIf 以仅在填充 url 时显示它。然后您需要清理 url。在查看更多。
