前言：
  基于【ionic】数据交互-get请求此文配置的内容上，进行以下操作.

1.在需要post请求的页面引入：

import { HttpHeaders,HttpClient } from '@angular/common/http';

2.在构造函数中引入：

public http:HttpClient

3.具体方法：

  AddConsumeLog(){
    const htttOptions = {
      headers:new HttpHeaders({'Content-Type':'application/json'})
    }
    var api ="http://XXX.XXX.XX.XX:XXXX/CardAddLog/AddConsumeLog";
    this.http.post(api,
    {id:0,
     cardId:'E000001',
     userId:'1',
     consumeTime:'2019-04-24',
     cash:'100',
     orderId:'1'},htttOptions).subscribe(response =>{
      console.log(response);
    })
  }
