Question

我正在创建一个控制台应用程序，我想在命令运行时从另一个URL获取数据

这就是我实现控制台控制器的方法

<?php
  namespace console\controllers;

  use yii\helpers\Console;
  use yii\console\Controller;
   ... other use imports
   use Yii;


class UserController extends Controller
{

  public function actionInit()
   {
     $urltofetchdata = "https://urltofetchjsondata"; //i expect to return json

     $datas= //how do i get the data here so that i can proceedby

      foreach($datas as $data){
        $user = new User();
        $user->name = $data->name;
        $user->email = $data->email;
        $user->save();

    }
   }
  }

以便用户输入：

./yii user/init

可以检索数据。

如果您的服务器上激活了allow_url_fopen，您可以使用file_get_contents远程获取数据;像这样的东西，

public function actionInit()
{
    $urltofetchdata = "https://urltofetchjsondata"; //i expect to return json
    $datas = json_decode(file_get_contents($urltofetchdata));

    foreach($datas as $data) {
        $user = new User();
        $user->name = $data->name;
        $user->email = $data->email;
        $user->save();
    }
}

如果您的服务器上禁用了allow_url_fopen，则可以使用cURL

public function actionInit()
{
    $urltofetchdata = "https://urltofetchjsondata"; //i expect to return json

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL, $urltofetchdata);
    $result = curl_exec($ch);
    curl_close($ch);

    $datas = json_decode($result);

    foreach($datas as $data) {
        $user = new User();
        $user->name = $data->name;
        $user->email = $data->email;
        $user->save();
    }
}

Yii2控制台从外部服务器获取数据
