Cron 作业的输出与在浏览器中运行脚本不同

Question

我在我的服务器上运行以下代码，该脚本在浏览器中运行良好，但是当我在 cronjob 中尝试它或通过以 root 身份登录的 shell 时，我会得到完全不同的输出。

通过浏览器输出：

• 登录并获取我想要的页面

通过 shell / cron 输出：

• 似乎没有登录，但获取页面内容将我重定向回登录页面。

我正在使用红帽 Linux 5

$fields_send = 'shopper_username=USERNAME&shopper_password=PASSWORD&Validate=1';

首先检查命令的输出，如果您以 Web 用户（通常是 www-data）身份执行它，

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，因此请确保您运行 cron 作业的用户可以写入文件“/ var/www/vhosts/domain.co.uk/httpdocs/store/cookie”。
