php - 使用单个连接编写多个发布请求 - PHP

Question

我正在使用以下代码片段写入服务器。

$fp = connect();
$sent_requests = 0;
function connect() {
    $addr = gethostbyname("example.com");
    $fp = fsockopen("$addr", 80, $errno, $errstr);
    socket_set_blocking( $fp, false );
    if (!$fp) {
        echo "$errstr ($errno)<br />\n";
        exit(1);
    } else{
        echo "Connected\n";
        return $fp;
    }
}


function sendTestCalls($load){
    global $fp, $sent_requests;
    if(!$fp){
        echo "reconnecting";
        $sent_requests = 0;
        //echo stream_get_contents($fp) . "\n";
        fclose($fp);
        $fp = connect();
    }
    $data = "POST /test HTTP/2.0\r\n";
    $data.= "Host: example.com\r\n";
    $data.= "Content-Type: application/json\r\n";
    $data.= "Content-Length: ".strlen($load)."\r\n";
    $data.= "Connection: Keep-Alive\r\n";
    $data.= "xYtU87BVFluc6: 1\r\n";
    $data.= "\r\n" . $load;

    $bytesToWrite = strlen($data);
    $totalBytesWritten = 0;

    while ($totalBytesWritten < $bytesToWrite) {
        $bytes = fwrite($fp, substr($data, $totalBytesWritten));
        $totalBytesWritten += $bytes;
    }

    $sent_requests++;
}
$time = time();
for($i=0; $i<1000; $i++) {
    sendTestCalls('{"justtesting": "somevalue"}');
}
fclose($fp);
$time_taken = time() - $time;//might be a bit inaccurate
echo "Time Taken: " . $time_taken . "\n";

当我检查我的服务器上的访问日志时，收到的发布请求少于 1000 个(在 0 到 900 的范围内)。我在这里做错了什么？

编辑1我想我的套接字超时了。在这种情况下重新连接时，我应该如何检查它是否已断开连接。我尝试使用 stream_get_meta_data($fp) 但没有效果。

尝试在每个请求之前插入:


$info = stream_get_meta_data($fp);
如果($信息['timed_out']){
fclose($fp);
$fp = 连接()；
}
