Question

我需要获取以下http调用的状态代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);

}

THX！

Answer 1

只需将您的代码修改为以下内容即可将responseStatus存储在字段中：

responseStatus: number;

//This method must return the status of the http response
confirmEmail(mailToken):Observable<String> {
//Edited for working with HttpClient on Angular >= 4.3
  return this.http.get(this.baseUrl+"users/activate?mailToken="+mailToken, {observe: 'response'})
                 .map((response: Response) => {
                   this.responseStatus = response.status;
                   return this.extractData(response);
                 }
                 .catch(this.handleError);

}

然后将其显示在组件HTML模板中：

<p class='responseStatus'>{{responseStatus}}</p>

使用替换HttpClient

的新http为Angular＆gt; = 4.3（包括7）版本添加答案

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标题：

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'));
  });

Check Documentation

Answer 3

这就是我的做法：

checkResponse() {
  this.http.get(this.url, { observe: 'response' })
  .subscribe(response => console.log(response.status));
}

使用Angular 7。

Answer 4

简单!!

在extractData函数中

extractData (res){
//res.status  will be your status code
// res.statusText  will be your status Text
}

Answer 5

    confirmEmail(mailToken):Observable<String> {
   return this.http.get(this.baseUrl+"users/activate?mailToken="+mailToken)
     .pipe(map(data => {
       return data.httpStatus
         }));
     .catch(this.handleError);
}

希望，这将解决您的问题。

不与我合作

使用aspnet核心在c＃中查看我的方法

    public IActionResult Insert([FromBody]TrocoSolidarioDTO x)
    {
        if (x == null)
        {
            return BadRequest();
        }
        try
        {
            return Ok("Working");
        }
        catch (Exception ex)
        {
            return BadRequest(ex.Message);
        }
    }
