cordova - Ionic 2 HTTP.post not send data

Question

I has a problem, When I post data to my api server.

My api server didn't get any data, It send from ionic app.

This is my api providers.

import { Injectable } from '@angular/core';
import { HTTP } from 'ionic-native';
import 'rxjs/add/operator/map';


@Injectable()
export class APIProvider {

  constructor() {}

  getProduct(){
    return new Promise(resolve => {
      let header = {"Content-Type": "application/json"}

      let body = {
        "data_1": "1234567890123",
        "data_2": "125615"
      }

      HTTP.post('https://ex.com/api/somethig', JSON.stringify(body), header)
      .then(data => {
        console.log(data.status);
        console.log(data.data); // data received by server
        console.log(data.headers);
        resolve(data);
      })
      .catch(error => {
        console.log(error.status);
        console.log(error.error); // error message as string
        console.log(error.headers);
        resolve(error);
      });
    });
  }
}

In api server (PHP), I try vardump($_POST);/ But it return array(0) {}

Console log

[15:20:15]  console.log: 200 
[15:20:15]  console.log: array(0) { } 
[15:20:15]  console.log: [object Object]

Answer 1

啊哈，我找到了答案。

刚改成"Content-Type": "application/json"。"Content-Type": "application/x-www-form-urlencoded"

Answer 2

尝试使用“@angular/http”。

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

constructor(public http: Http) {}
let body = { data_1: "1234567890123", data_2: "125615" };

return new Promise((resolve, reject) => {
  let headers = new Headers();
  headers.append('Content-Type', 'application/json');
  this.http.post('https://ex.com/api/somethig', JSON.stringify(body), {headers: headers})
    .subscribe(res => {
      resolve(res);
    }, (err) => {
      reject(err);
    });
});
