Question

遇到此错误

代码： Post_providers.ts

import { Injectable } from '@angular/core';
import { Http, Headers, RequestOptions } from '@angular/http';
import 'rxjs/add/operator/map';


@Injectable()
export class PostProviders {
  server: string = "http://localhost/server_api/"

  constructor(public http: Http){
  }

  postData(body, file){

    let type = "application/json; charset=UTF-8";
    let headers = new Headers ({'Content-type': type});
    let options = new RequestOptions({headers: headers});

    return this.http.post(this.server + file, JSON.stringify(body), options)
    .map(res => res.json());
  }
}

file_aksi.php

import { Injectable } from '@angular/core';
import { Http, Headers, RequestOptions } from '@angular/http';
import 'rxjs/add/operator/map';


@Injectable()
export class PostProviders {
  server: string = "http://localhost/server_api/"

  constructor(public http: Http){
  }

  postData(body, file){

    let type = "application/json; charset=UTF-8";
    let headers = new Headers ({'Content-type': type});
    let options = new RequestOptions({headers: headers});

    return this.http.post(this.server + file, JSON.stringify(body), options)
    .map(res => res.json());
  }
}

config.php

define('Db_name', 'ionic_app');
define('Db_user', 'root');
define('Db_password', '');
define('Db_host', 'localhost');

$mysqli = new mysqli(Db_name, Db_host, Db_password, Db_user);

我仍在尝试解决此问题，但仍然没有运气。我正在努力解决最近两天以来的错误，但是我不明白我做错了什么。
