(Angular 2 HTTP GET with TypeScript error http.get(...).map is not a function in [null] )

(角2 HTTP GET与打字稿错误HTTP . GET(…)。map不是[null]中的函数)

I'm using Angular2@2.0.0-beta.1
我用Angular2@2.0.0-beta.1
Rxjs (rxjs@5.0.0-beta.1) is successfully imported when I check console/resources in console.
Rxjs (rxjs@5.0 -beta.1)在检查控制台/资源时成功导入。

I tried different imports:

我试着不同的进口:

import 'rxjs/add/operator/map';

导入“rxjs /添加/运营商/地图”;

import 'rxjs/rx';

进口“rxjs / rx”;

But I keep getting the error http.post(...).map is not a function

但是我一直在获取错误http.post(…)。map不是函数

update - code context

更新,代码上下文

let body = "email=" + email + "&password=" + password;
let headers = new Headers();
headers.append('Content-Type', 'application/x-www-from-urlencoded');
this.http.post('http://angular.app/api/v1/auth') // angular.app is laravel backend
      .map( (responseData) => {
          return responseData.json();
      })

It seems that Angular2 beta.1 requires RxJS 5.0.0-beta.0. Perhaps it's the cause of your problem.

看起来是Angular2贝塔。1需要RxJS 5.0.0-beta.0。也许这就是你的问题所在。

If I try this in my package.json file:

如果我在包裹里尝试一下。json文件:

"dependencies": {
    "angular2": "2.0.0-beta.1",
    "systemjs": "0.19.6",
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.33.3",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.1",
    "zone.js": "0.5.10"
},

And I have the error that Angular2 requires RxJS 5.0.0-beta.0.

我有一个错误，Angular2需要RxJS 5。0。0。

You need to add the HTTP_PROVIDERS within the second parameter of your bootstrap function.

您需要在引导函数的第二个参数中添加http_provider。

For me the http.post(...).map() works as expected. I do need the import 'rxjs/Rx'

对于我来说，http.post(…).map()工作正常。我需要导入'rxjs/Rx'

import {Component} from 'angular2/core';
import {Http} from 'angular2/http';
import 'rxjs/Rx';
@Component({
  selector: 'my-app',
  template: `
    <h1>{{title}}</h1>
    <p>Test result {{result | json}}</p>
    `
})
export class App implements OnInit{
 public title = 'my title';
 public result : String;

constructor(private _http : Http) {
  _http.post('http://jsonplaceholder.typicode.com/posts')
    .map(res => res.json())
    .subscribe(
      data => this.result = data,
      err => console.log('ERROR!!!'),
      () => console.log('Got response from API', this.result)
    );
  }
}
