Question

我正在使用以下代码段写入服务器。

$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，收到的请求少于1000个（范围为0到900）。我在这里做错了什么？

EDIT1 我想我的插座超时了。我该怎么做才能检查它是否在这种情况下重新连接断开连接。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此内容：

<packs> <pack name="Core" required="yes"> <description>Core Installation Files</description> <file src="myapplication.jar" targetdir="/Users/manjirilakhote/Izpack/extract" override="true" unpack="true" /> </pack> </packs>

我在那时使用php_curl和KEEP-ALIVE

找到了解决方法

这是我的更新版本：

function sendCall(&$curl_handle, $data){
   curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, "POST");
   curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $data);
   curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, true);
   curl_setopt(
       $curl_handle,
       CURLOPT_HTTPHEADER,
       array(
           'Content-Type: application/json',
           'Connection: Keep-Alive',
           'Content-Length: ' . strlen($data)
       )
   );
   $response = curl_exec($curl_handle); //Check response?
   if($err = curl_error($curl_handle)) {
       error_log("Error - $err Status - Reconnecting" );
       $curl_handle = curl_init(curl_getinfo($curl_handle, CURLINFO_EFFECTIVE_URL));
       sendCall($curl_handle, $data);
   }
}

这个功能给了我一个几乎永远活着的连接。（从未在一周内获得错误日志）。希望它可以帮助任何人寻找相同的东西。
