php - 无法在 php 内部使用 curl 调用 httprequest

Question

我设置了一个要玩的 symfony 项目，然后在 Controller 中创建了两条路线。在路由 1 中，使用 curl 调用路由 2。如下所示:

/**
 * @Route("/", name="user_list")
 */
public function indexAction(Request $request)
{

    $url = 'http://localhost:8000/test';
    $headers = array( 'Authorization' => 'Basic dXNlcm5hbWU6cGFzc3dvcmQ=', 'Content-Type' => 'application/json' );
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

    $result = curl_exec($ch);
    curl_close($ch);
    var_dump( $result );

    // replace this example code with whatever you need
    return $this->render("user/user_list.html.twig");
}

/**
 * @Route("/test", name="user_test")
 */
public function testAction(Request $request)
{
    return new Response('abc', 200);
}

如果我单独运行路由器 2，它将返回 abc，但如果我运行路由器 1，它将一直等待连接。

我该如何解决？在 php 等、socket 中有什么要配置的吗...？有人可以帮帮我吗？谢谢

/**

 */
public function indexAction(Request $request)
{

    $url = 'http://localhost:8000/test';
    $headers = array( 'Authorization' => 'Basic dXNlcm5hbWU6cGFzc3dvcmQ=', 'Content-Type' => 'application/json' );
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

    $result = curl_exec($ch);
    if($result === false) { // Get curl error with this
        echo 'Curl error: ' . curl_error($ch);
    }


    curl_close($ch);
    var_dump( $result );

    // replace this example code with whatever you need
    return $this->render("user/user_list.html.twig");
}
