php脚本的异步执行正在使用经过身份验证的会话


Async execution of php-script is working with authenticated session

我正在尝试异步运行脚本。在Stackoverflow上找到如何做到这一点是没有问题的。问题是,我正在尝试我发现的一个例子,但它不起作用。脚本运行时不会在error_log中输出错误。

我的主php脚本:

function backgroundPost($url){
    $parts=parse_url($url);
      $fp = fsockopen($parts['host'],
              isset($parts['port'])?$parts['port']:80,
              $errno, $errstr, 30);

      if (!$fp) {
          return false;
      } else {
          $out = "POST ".$parts['path']." HTTP/1.1'r'n";
          $out.= "Host: ".$parts['host']."'r'n";
          $out.= "Content-Type: text/plain'r'n";
          $out.= "Content-Length: ".strlen($parts['query'])."'r'n";
          $out.= "Content-Length: ".strlen($parts['query'])."'r'n";
          $out.= "Connection: Close'r'n'r'n";
          if (isset($parts['query'])) $out.= $parts['query'];
          fwrite($fp, $out);
          fclose($fp);
          return true;
      }
    }
    //Example of use
    backgroundPost('http://192.168.1.107/smic/testarea/runner.php?id=1');

fwrite()的响应为"155"。

backgroundPost正在返回"true"。

runner.php:

ignore_user_abort(true);
set_time_limit(50);
error_log("RUNNING!"); 

为什么"RUNNING!"注释被写入错误日志?这就像scipt实际上并没有执行一样。

当直接访问runner.php(在backgroundPost中发布URL)时,脚本会按预期工作。

两个脚本都具有apache:apache的777权限。

在上运行

  • Linux/CNTOS 6.2
  • PHP 5.3.3
  • Apache 2.2.15

这可能与我使用的是经过身份验证的会话,而经过身份验证后的用户当然不是运行脚本的apache有关吗?

使用CURL进行测试

@jprofitt建议我也尝试过卷曲:

async_curl.php:

$ch = curl_init("http://192.168.1.107/");
$fp = fopen("http://192.168.1.107/smic/testarea/runner.php", "r");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC ) ;
curl_setopt($ch, CURLOPT_USERPWD, "kaand:xIWGWt0DNVriw"); 
curl_setopt($ch, CURLOPT_HEADER, true); 
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
$info = curl_getinfo($ch);
echo print_r($info);
curl_close($ch);
fclose($fp);

Tis是从curl_getinfo($ch):打印的

Array
(
    [url] => http://192.168.1.107/
    [content_type] => text/html; charset=UTF-8
    [http_code] => 302
    [header_size] => 411
    [request_size] => 103

    [redirect_time] => 0
    [certinfo] => Array
        (
        )
    [redirect_url] => http://192.168.1.107/login.php
)
1

我确实尝试过$ch=curl_init("http://192.168.1.107/");然后我在网上收到了消息"需要授权"。在error_log中,我得到了运行php.所需的HTTP/1.1 401授权

在执行'curl_setopt($ch,CURLOPT_File,$fp);'时,我确实在error_log中收到了$fp"不是有效的文件句柄资源"的投诉。

数组末尾有一个重定向到登录页的问题,这可能与该问题有关吗?

所以,我遇到的问题与runner.php的限制区域有关。无论我使用curl还是fsockopen,我都需要验证请求。在这里,我包含了fsockopen和curl对受限区域进行异步请求的解决方案。

fsockopen:

function backgroundPost($url){        
    $parts=parse_url($url);
    echo $parts['path']."<br/>"; 
    echo $parts['host']."<br/>"; 
    echo $url;
  $fp = fsockopen($parts['host'],  
          isset($parts['port'])?$parts['port']:80,
          $errno, $errstr, 10);
 $auth = base64_encode("kaand:kaand123");
  if (!$fp) {
      return false;
  } else {
      $out = "POST ".$parts['path']." HTTP/1.1'r'n";
      $out.= "Host: ".$parts['host']."'r'n";
      $out.= "User-Agent: Anonymous'r'n";
      $out.= "Content-Type: text/plain'r'n";
      $out.= "Authorization: Basic ".$auth;
      $out.= "Content-Length: ".strlen($parts['query'])."'r'n";
      $out.= "Connection: Close'r'n'r'n";
      if (isset($parts['query'])) $out.= $parts['query'];
      fwrite($fp, $out);
      fclose($fp);
      return true;
  }
}

使用示例:

backgroundPost('http://192.168.1.107/smic/testarea/runner.php?id=1');

卷曲:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://192.168.1.107/smic/testarea/runner.php");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC ) ;
curl_setopt($ch, CURLOPT_USERPWD, "kaand:kaand123"); //Don't use the sha1-value
curl_setopt($ch, CURLOPT_HEADER, true); 
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);

runner.php

do whatever...

我想我会选择fsockopen,认为这是一个比超时更好的解决方案,因为超时会迫使你至少有一些等待时间。如果会有很多流量,哪怕1秒也能积累。。。
