Question

此代码正在调用Jasper服务器以使用SAML身份验证建立连接。当执行代码时，它跳到handleError例程，尽管它是200，但是仍然存在解析错误。 这是执行代码后的控制台信息

Server Error Status: 200  <-- coming from the error routine

<b>Component code</b>

  ngOnInit(): void {
    console.log('In Report Component init');
    this.connectToJasper();
  }

  connectToJasper() {
    this.samlConnectionService.
    getSAMLConnection().
    subscribe(
      data => this.connected = true,
      error => console.log('Error Connecting to Jasper Server: ' + error)
    );
    console.log('In connectToJasperconnected');
  }

<b>Service code</b>

jasperSamlURL = 'THE URL';

  getSAMLConnection(): Observable<any>  {
   // return this.httpClient.get<any>(this.jasperSamlURL, { responseType: 'text'})
   // return this.httpClient.post<any>(this.jasperSamlURL, { observe: 'response'})
    return this.httpClient.get(this.jasperSamlURL, { observe: 'response', responseType: 'text' })
    .pipe(
      tap(response => {
        console.log('Http Response Status: ' + response.status);
        console.log('Http Response text: ' + response.statusText);
        console.log('Http Response Type: ' + response.type);
        console.log('Http Response Body: ' + response.body);
      }),
      map(response => this.HttpResponseCode = response.status),
       catchError(this.handleError)
      );
  }

  public handleError(err) {
    if (err instanceof HttpErrorResponse) {
      // Server side Error
      this.HttpResponseCode = err.status;
      console.log(err);
      console.log('Server Error Status: ' + err.status);
    } else {

      this.HttpResponseCode = err.status;
      console.log('Client Error Status: ' + err.status);
    }
    return throwError(err);
