如何从PHP返回到Ionic Controller？

<?php
// 返回JSON格式的数据
$data = array("name" => "John", "age" => 30);
echo json_encode($data);
?>

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

// ...

constructor(private http: HttpClient) {}

getDataFromPHP() {
  this.http.get('http://your-php-api-url').subscribe((data) => {
    // 处理从PHP返回的数据
    console.log(data);
  });
}

ionic generate plugin MyPlugin

import { Injectable } from '@angular/core';
import { Plugin, Cordova } from '@ionic-native/core';

@Plugin({
  pluginName: 'MyPlugin',
  plugin: 'cordova-plugin-my-plugin',
  pluginRef: 'cordova.plugins.MyPlugin',
  platforms: ['iOS', 'Android']
})
@Injectable()
export class MyPlugin {
  @Cordova()
  getDataFromPHP(): Promise<any> {
    return;
  }
}

import { MyPlugin } from '@ionic-native/my-plugin/ngx';

// ...

constructor(private myPlugin: MyPlugin) {}

getDataFromPHP() {
  this.myPlugin.getDataFromPHP().then((data) => {
    // 处理从PHP返回的数据
    console.log(data);
  });
}
