Question

PS ：我检查过很多帖子，但无法得到满意的解决方案。（因此，如果您将其标记为重复，那么请分享答案）

我正在使用离子2，它具有非常基本的功能，即向服务器发送post请求。我使用的很简单import { Http } from '@angular/http';。

代码

    var link = 'https://mywebsite.com/myws/Login';
    var data = JSON.stringify({ username: this.username, password: this.password });

    this.http.post(link, data)
      .subscribe(data => {
        console.log(data);
      }, error => {
        console.log("Oooops!");
    });

的package.json
