嗨，我正在使用apns发送IOS推送通知，并在php中卷曲，并收到此错误消息。

我也定义了“ CURL_HTTP_VERSION_2_0”，但仍然出现此错误：

意外的HTTP / 1.x请求：POST / 3 / device /

这是我的代码：

       $key_file = XXXXXX';
       $secret = null; 
       $private_key = JWKFactory::createFromKeyFile($key_file, $secret, [
                'kid' => '3W6B5LQQHX',
                'alg' => 'ES256',
                'use' => 'sig',
    ]);

    $payload = [
        'iss' => 'RUK725A7V4',
        'iat' => time(),
    ];

    $header = [
        'alg' => 'ES256',
        'kid' => $private_key->get('kid'),
    ];

    $jws = JWSFactory::createJWSToCompactJSON(
                    $payload, $private_key, $header
    );


    if (!defined('CURL_HTTP_VERSION_2_0')) {
        define('CURL_HTTP_VERSION_2_0', 3);
    }

        $http2_server = 'https://api.development.push.apple.com'; 
        $app_bundle_id = 'com.MD.example';

        $token = $device->device_id;
        $url = "{$http2_server}/3/device/{$token}";

        // headers …
