以角度2：400（错误请求）搜索错误

Question

在项目中，当用户搜索“员工”时，他应该被重定向到搜索“员工”的个人资料页面。

问题出现在组件ProfilesResult：

的ngOnInit方法中

  ngOnInit(): void {
    this.loadItemElementTemplate().takeUntil(this.ngUnsubscribe).subscribe(x => {
        this.itemElement = x;
    });
    this.activatedRoute.params.takeUntil(this.ngUnsubscribe).subscribe(params => {
        let profileId = params['id'];
        if (profileId) {
            this.profileIdQueryParam = profileId;
        }
    });
    setTimeout(() => {
        this.profileIdScroll = this.profileIdQueryParam;
    })
    console.log("Profile results ngOnInit");
}

这是被称为“ngOnInit（）”的方法：

1. `

   private loadItemElementTemplate() {
     return this.dataService.loadActionWidget(this.path).map((data: any) => {
       let itemElement: UiElement = JSON.parse(data.Data.WidgetJson);
       return itemElement;
    });
   }`
   
   
   loadActionWidget(path: string) {
     return this.requests.get(environment.actionWidgetDefinitionUrl + path,      
       this.options, null);
    }
   
    get(url: string, options: RequestOptions, params: any): Observable<any> 
     {
       return this.http.get(url, options)
         .map((res: any) => res.json())
         .catch((error: any) => Observable.throw(error.json()) || 'Server 
          error');
     }
   
   
   
    NgOnInit of profile-result.component.ts 
       ngOnInit(): void {    
      this.loadItemElementTemplate().takeUntil(this.ngUnsubscribe)
       .subscribe(x => {
         this.itemElement = x;
       });
       this.activatedRoute.params.takeUntil(this.ngUnsubscribe)
         .subscribe(params => {
            let profileId = params['id'];
          if (profileId) {
             this.profileIdQueryParam = profileId;
          }
        });
         setTimeout(() => {
            this.profileIdScroll = this.profileIdQueryParam;
         })
          console.log("Profile results ngOnInit");
        }
   

错误：
