Cron作业有不同的输出，然后在浏览器中运行脚本

Question

我在我的服务器上运行以下代码，该脚本在浏览器中正常工作，但是当我在cronjob中或通过shell以root用户身份登录时尝试它得到完全不同的输出。

输出通过浏览器：

• 日志中，并获取网页，我想

通过shell/cron的输出：

• 似乎没有登录，但得到该页面的内容将我重定向回登录页面。

我使用的Red Hat Linux 5

<?php 

$url = "http://www.domain.com/shopper_lookup.asp"; // the url where to send the request 
$fields_send = 'shopper_username=USERNAME&shopper_password=PASSWORD&Validate=1'; 
$agent = "Opera/9.63 (Windows NT 5.1; U; en-GB) Presto/2.1.1"; 
$reffer = "http://www.domain.com/login.html"; 
$cookie_file_path = "/var/www/vhosts/domain.co.uk/httpdocs/store/cookie"; // Cookie File Path with CHMOD 777 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_send); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($ch, CURLOPT_REFERER, $reffer); 
curl_setopt($ch, CURLOPT_USERAGENT, $agent); 
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); 
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); 
$result_source = curl_exec($ch); 

var_dump($ch); 

echo $result_source; 




$url = "http://www.domain.com/receipt.asp?ms=&order_id=ordernumber"; // the url where to send the request 
$agent = "Opera/9.63 (Windows NT 5.1; U; en-GB) Presto/2.1.1"; 
$reffer = "http://www.domain.com/contents.asp?ms="; 
$cookie_file_path = "/var/www/vhosts/domain.co.uk/httpdocs/store/cookie"; // Cookie File Path with CHMOD 777 

curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_GET, 1); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($ch, CURLOPT_REFERER, $reffer); 
curl_setopt($ch, CURLOPT_USERAGENT, $agent); 
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); 
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); 
$result_source = curl_exec($ch); 


echo $result_source; // Print the result page 


?>

首先检查命令的输出，如果你执行它作为你的网络用户（通常是www数据）

su www-data /usr/bin/php /var/www/vhosts/domain.co.uk/httpdocs/store/curl_test.php 

如果有效，那么这是一个权限错误，因此请确保您正在运行cron作业的用户可以写入文件“/var/www/vhosts/domain.co.uk/httpdocs/store/cookie”。
