使用'@angular/common/http'中的HttpErrorResponse和HttpResponse

apiCall() {
  let headers = new HttpHeaders();
  headers = headers.set('Content-Type', 'application/json');
  headers = headers.set('Authorization', `Bearer ${this.token}`);

  this.http.post<HttpResponse<any>>('URL', { data }, { headers }).subscribe(response => {
      console.log(response.status) // log status code
  }, (e: HttpErrorResponse) => console.log(e.status))

}

如果您使用的是HttpClient，下面是一个示例：

this.http.post(myRequest, body, { headers : myHeaders, observe: 'response' }).subscribe(
  data => {
    console.warn(JSON.stringify(data, null, 2));
  },
  error => {
    console.error(error.errorMessege);
});

您需要将observe: 'response'添加到options参数中，这样您就可以在订阅中获得整个响应。

public apiCall(): void {
    let header1: HttpHeaders = new HttpHeaders();
    header1 = header1.append('Content-Type', 'application/json');
    header1 = header1.append('Authorization', `Bearer ${this.token}`);

    this.http.post<HttpResponse<any>>(
      'URL',
      {
        dataSentHere: 'data',
      },
      {
        headers: header1,
        observe: 'response',
      },
    ).subscribe(
      (data: HttpResponse<any>) => {
        if (data.status === 200 || data.status === 202) {
          console.log(`Got a successfull status code: ${data.status}`);
        }
        console.log(`This contains body: ${data.body}`);
      },
      (err: HttpErrorResponse) => {
        if (err.status === 403) {
          console.error('403 status code caught');
        }
      },
    );
  }
