Yii2控制台从外部服务器获取数据

问题描述：

I am creating a console application where I would like to fetch data from another url whenever the command is run

This is how I have implemented the console controller

<?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();

    }
   }
  }

so that when a user types:

./yii user/init

the data can be retrieved.

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 p >

这就是我实现控制台控制器的方法 p>

 ＆lt;？php 
命名空间控制台\控制器; 
 
使用yii \ helpers  \ console; 
使用yii \ console \ Controller; 
 ...其他使用导入
使用Yii; 
 
 
class UserController扩展Controller 
 {
 
公共函数actionInit（）
 {\  n $ urltofetchdata =“https：// urltofetchjsondata”;  //我希望返回json 
 
 $ datas = //如何在这里获取数据，以便我可以继续
 
 foreach（$ datas as $ data）{
 $ user = new User（）  ; 
 $ user-＆gt; name = $ data-＆gt; name; 
 $ user-＆gt; email = $ data-＆gt; email; 
 $ user-＆gt; save（）; 
 
} \  n} 
} 
  code>  pre> 
 
 以便用户输入： p> 
 
 
  ./ yii user / init \  n  code>  pre> 
 
 可以检索数据。 p> 
  div>

答

if allow_url_fopen is activated on your server you can use file_get_contents to grab the data remotely; something like this,

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();
    }
}

if allow_url_fopen is disabled on your server, you can use 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();
    }
}
