我正在尝试为苹果推送通知创建服务器端连接。首先,我要求用户(可能是 ios 开发人员)提供 Apple 提供的 .cer 和 .p12 文件,以使其成为 .pem 文件。
下面是 .pem 证书的创建。
$dir = $this->directory.'/certificates';
$password = 'a_user_password';
$certificate = $dir.'/certificate.cer';
$key_password = $dir.'/key.p12';
exec('openssl x509 -inform der -in '.$certificate.' -out '.$dir.'/certificate.pem');
exec('openssl pkcs12 -nocerts -out '.$dir.'/key.pem -in '.$key_password.' -passout pass:'.$password.' -passin pass:'.$password);
$filename = $key_password;
$results = array();
$worked = openssl_pkcs12_read(file_get_contents($filename), $results, $obj->password);
if($worked) {
$current = file_get_contents($dir.'/key.pem');
$current .= $results['pkey'];
file_put_contents($dir.'/key.pem', $current);
} else {
echo openssl_error_string();
}
exec('cat '.$dir.'/certificate.pem '.$dir.'/key.pem > '.$dir.'/apns_certificate.pem');
到现在为止还挺好。我已经通过命令行通过以下方式测试了上面生成的 apns_certificate.pem 与苹果成功:
s_client -connect gateway.sandbox.push.apple.com:2195 -cert certificate.pem -key key.pem
但是,当我尝试通过 PHP 连接 apns 时,我不能。遵循我尝试过的最后一个 php 代码,我已经看到对其他人有效:
$this->certificate = ROOT.'/certificates/apns_certificate.pem';
$this->socket = 'ssl://gateway.push.apple.com:2195';
if (!file_exists($this->certificate)) {
$this->error = 'Certificate file not found';
return false;
}
$this->stream_context = stream_context_create();
$this->stream_options = array(
'ssl' => array(
'local_cert' => $this->certificate,
'passphrase' => 'a_user_password', //same with the one used in my previous code
)
);
$success = stream_context_set_option($this->stream_context, $this->stream_options);
if ($success == false) {
$this->error = 'Secure connection failed';
return false;
}
$this->socket_client = stream_socket_client($this->socket, $con_error, $con_error_string, $this->timeout, STREAM_CLIENT_CONNECT, $this->stream_context);
if ($this->socket_client === false) {
$this->error = $con_error_string;
return false;
} else {
return true;
}
上面的代码返回一个错误:警告:stream_socket_client():SSL 操作失败,代码为 1。OpenSSL 错误消息:错误:14094416:SSL 例程:SSL3_READ_BYTES:sslv3 警报证书未知警告:stream_socket_client():无法连接到 ssl: //gateway.push.apple.com:2195
预先感谢您的帮助!
