Question

我的contact包含一个对象。我想发送到http.post方法。下面是我的代码，我应该在哪里放置contact对象作为参数。请给出与http相关的链接.post API，如果有的话。代码：

createContacts(contact) {
    console.log('the contact inside subscribe function',contact);
    let headers = new Headers();
    headers.append('Content-Type', 'application/json');
    this.http.post('http://localhost:8080/contacts',{headers : headers}).subscribe(res => {
      console.log('inside postmehtod of sub.function', res.json());//only objects

    });

  }

package.json

  "name": "contactlist",
  "version": "0.1.0",
  "description": "A sample Node.js app using Express 4",
  "engines": {
    "node": "5.9.1"
  },

Link to http post api根据要求

Typescript post API：post(url: string, body: any, options?: RequestOptionsArgs) : Observable<Response>

示例：

createContacts(contact) {
    let headers = new Headers();
    headers.append('Content-Type', 'application/json');
    this.http.post('http://localhost:8080/contacts', contact, {headers : headers})
      .subscribe(res => {
         console.log('inside postmehtod of sub.function', res.json());//only objects
      })
  }

如何将对象发送到http.post请求？
