Angular2 basic GET请求失败(可能是TS编译问题？)

import { Http } from '@angular/http';

constructor(private http: Http) { }

getData() {
  this.http.get('https://api.example.com/data')
    .subscribe(response => {
      // 处理成功响应
      console.log(response.json());
    }, error => {
      // 处理错误响应
      console.error(error);
    });
}

"compilerOptions": {
  "target": "es5",
  "module": "commonjs",
  "lib": ["es2015", "dom"],
  // 其他配置项...
}

"proxyConfig": "proxy.conf.json"

{
  "/api": {
    "target": "https://api.example.com",
    "secure": false,
    "changeOrigin": true
  }
}
