Question

我有下面的请求。但是它给出了401 Unauthorized错误。

var headers = new Headers();
        headers.append('Content-Type': 'application/json;charset=UTF-8');

        this.http.get(urgentPostURL + encodeURIComponent(this.urgentpost.comment))
        .map((res:Response) => res.json())
        .subscribe(data => { 

          this.result = data;
          console.log('UrgentPost Result : ' + this.result.Success);

          if (this.result.Success == true) {
              console.log("SUCESSS");
          } else {
              console.log("FAILED");
          }

        },err => console.error(err),() => console.log('done'));

我在这里做错了什么？

更新到以下代码后，我仍然得到401：

var headers = new Headers();
        headers.append('Content-Type': 'application/json;charset=UTF-8');
        headers.append('Authorization', 'Basic ' + btoa("123" + ':' + "123"));
        this.http.get(urgentPostURL + encodeURIComponent(this.urgentpost.comment), { headers: headers })
        .map((res:Response) => res.json())
        .subscribe(data => {

一般：

Request Method:GET
Status Code:401 Unauthorized

我似乎服务器需要身份验证。您没有为您的通话定义Authorization标题。

以下是HTTP基本身份验证的示例：

var headers = new Headers();
headers.append('Content-Type': 'application/json;charset=UTF-8');
headers.append('Authorizcation', 'Basic '+btoa(username + ':' + password));

this.http.get(urgentPostURL + encodeURIComponent(
          this.urgentpost.comment,
          { headers: headers })
    .map((res:Response) => res.json())
    (...)

不要忘记为您的请求指定标题并导入Headers类。
