我希望能够使用CURL读取SSL证书信息.从Linux控制台我得到这个响应头:

但是使用CURL,标题要短得多:

我正在尝试从 PHP 向我的 websocket aws api 网关发送一个即发即弃的请求。

我已经设置了一个名为“发送消息”的操作。

这是我正在使用的代码：

$protocol = "ssl";
$host = "<myendpoint>.amazonaws.com";
$port = 443;
$path = "/<mystage>/";
$timeout = 2000;

$socket = pfsockopen($protocol . "://" . $host, $port,
                    $errno, $errstr, $timeout);

$content = "{'action': 'sendmessage', 'data': 'test'}";
$body = "POST $path HTTP/1.1\r\n";
$body .= "Host: $host\r\n";
$body .= "Content-Type: application/json\r\n";
$body .= "Content-Length: " . strlen($content) . "\r\n";
$body .= "Connection: Close\r\n\r\n";
$body .= $content;
$body .= "\r\n";

fwrite($socket, $body);

然而，什么也没有发生。

如果我使用 wscat，例如：

wscat -c wss://<my-endpoint>.amazonaws.com/<my-stage> …
