 $cxContext = stream_context_create($opts);

 $sFile = file_get_contents("http://127.0.0.1/reponse.php", false, $cxContext);

// 设置cURL 参数，要求结果保存到字符串中还是输出到屏幕上。

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//是否获得跳转后的页面

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_close($ch);

echo $data;

   $post_data = http_build_query($url_data);

   $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt($ch, CURLOPT_POST, 1);

    curl_setopt($ch,  CURLOPT_POSTFLELDS, $post_data);

    $data = curl_exec($ch);

    curl_close($ch);

    echo $data;
