Question

我能够打开一个PHP TCP侦听器套接字，但是我不知道如何解析缓冲区。连接到我的套接字的客户端发送带有附加边界数据（带有xml文件和图像文件）的text / html。

我该如何解析响应以在一侧获取XML文件而在另一侧获取图像？

server = socket_create_listen(8086);
socket_getsockname($server, $addr, $port);
if (!$server) {
    $message = 'Start TCP socket: Ko. Could not create socket.';
    $this->logger->info($message);
    die($message);
} else {
    $message = 'Start TCP socket: Ok. TCP socket opened on: ' . $addr . ':' . $port . '.';
    $this->logger->info($message);

    while ($c = socket_accept($server)) {
        socket_getpeername($c, $raddr, $rport);
        $this->logger->info("Received Connection from $raddr:$rport\n");

        $data = '';
        while ($bytes = socket_recv($c, $r_data, 1024, MSG_WAITALL)) {
            $data .= $r_data;
        }

        //Edited: Explode with double line and got data
        $parsedData = explode("\r\n\r\n", $data);
        $xml = new \SimpleXMLElement($parsedData[2]);

        print_r($xml);

        else {
            echo "socket_recv() failed; reason: " . socket_strerror(socket_last_error($c)) . "\n";
        }

        socket_close($c);
    }
}
fclose($server);

这是我收到的输出：

已编辑：我可以使用“爆炸”功能来获取XML数据，但是我不知道如何将2张图像作为图像文件来获取。有什么建议吗？

任何帮助将不胜感激！

谢谢！

我在这里写下我的最终解决方案：

1-将字符串中的数据分解为数组（使用\ r \ n \ r \ n）：

choco list --source=schily-artifacts

2-XML实际上位于位置2（位置0和1包含POST HTTP标头和边界起始部分）：

$parsedData = explode("\r\n\r\n", $data);

图像在位置4上（数组位置3包含标头，例如Content-Disposition，必须跳过）：

将数据另存为图像的代码为：

$xml = new \SimpleXMLElement($parsedData[2]);

在PHP socket_listener上解析套接字数据
