如何在php中进行非阻塞调用

发布于 2024-12-27 01:46:06 字数 482 浏览 2 评论 0原文

我正在使用 php 脚本上传大量文件。我正在使用 CURL 命令。远程服务器仅接受 POST 请求。但是当我执行下面的脚本时，它会处理第一个请求并等待第一个文件上传。有没有办法使其非阻塞并同时运行 2 个curl 上传请求。找到下面的代码示例。

<?php
  $arr= array(somefile1.txt,somefile2.txt);
  for ( $i=0;$i<2;$i++) {
     $cmd = "curl  -F name=aaa -F type=yyy  FileName=@/xxxxx/xxxx/$arr[$i] http://someurl.com";
     print "Executing file ";
     shell_exec("nohup  $cmd  2> /dev/null & echo $!" );
     print "=======  done ================";
  }
?>

I am using a php script to upload lot of files. I am using the CURL command . The remote server accepts only POST requests. But when I execute the below script it processes the first request and waits until the first file is uploaded. Is there a way to make it non blocking and run simultaneous 2 curl upload requests .Find the code sample below.

<?php
  $arr= array(somefile1.txt,somefile2.txt);
  for ( $i=0;$i<2;$i++) {
     $cmd = "curl  -F name=aaa -F type=yyy  FileName=@/xxxxx/xxxx/$arr[$i] http://someurl.com";
     print "Executing file ";
     shell_exec("nohup  $cmd  2> /dev/null & echo $!" );
     print "=======  done ================";
  }
?>

我相信您可能需要 curl_multi_init。这是一个出站示例；它必须针对您的入站问题进行调整。这看起来比你自己分叉多个线程更干净。

<?php
// create both cURL resources
$ch1 = curl_init();
$ch2 = curl_init();

// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, "http://lxr.php.net/");
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch2, CURLOPT_URL, "http://www.php.net/");
curl_setopt($ch2, CURLOPT_HEADER, 0);

//create the multiple cURL handle
$mh = curl_multi_init();

//add the two handles
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);

$active = null;
//execute the handles
do {
    $mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($active && $mrc == CURLM_OK) {
    if (curl_multi_select($mh) != -1) {
        do {
            $mrc = curl_multi_exec($mh, $active);
        } while ($mrc == CURLM_CALL_MULTI_PERFORM);
    }
}

//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_close($mh);

?>

I believe you may want curl_multi_init. Here is an outbound example; it will have to be adapted for your inbound problem. This seems cleaner than you forking multiple threads yourself.

<?php
// create both cURL resources
$ch1 = curl_init();
$ch2 = curl_init();

// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, "http://lxr.php.net/");
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch2, CURLOPT_URL, "http://www.php.net/");
curl_setopt($ch2, CURLOPT_HEADER, 0);

//create the multiple cURL handle
$mh = curl_multi_init();

//add the two handles
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);

$active = null;
//execute the handles
do {
    $mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($active && $mrc == CURLM_OK) {
    if (curl_multi_select($mh) != -1) {
        do {
            $mrc = curl_multi_exec($mh, $active);
        } while ($mrc == CURLM_CALL_MULTI_PERFORM);
    }
}

//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_close($mh);

?>
