angular - 获取状态码 http.get response angular2

Question

我需要获取以下http调用的状态码并将其作为字符串返回

//This method must return the status of the http response
confirmEmail(mailToken):Observable<String>{

     return this.http.get(this.baseUrl+"users/activate?mailToken="+mailToken)
                     .map(this.extractData)
                     .catch(this.handleError);

}

谢谢!

为 Angular >= 4.3(包括 11)版本添加新的 HttpClient 替换 http

import {HttpClientModule} from '@angular/common/http'; // Notice it is imported from @angular/common/http instead of @angular/http

如何获取响应代码或任何其他 header :

http.get(
   `${this.baseUrl}users/activate?mailToken=${mailToken}`,
    {observe: 'response'}
)
  .subscribe(response => {
    
    // You can access status:
    console.log(response.status);
    
    // Or any other header:
    console.log(response.headers.get('X-Custom-Header'));
  });

如@Rbk 的评论所述，

对象 {observe: 'response'} 使完整的响应对象可用。
