REMOTE_ADDR为空,不包含在SERVER数组中

Question

搬到新服务器后,我遇到了一个奇怪的问题.用于获取邮件的cron检查授权的IP,其中一个默认为127.0.0.1

它在移动后停止工作,因为未填充REMOTE_ADDR变量.它是从浏览器调用时,但不是从cron内部运行或从php运行控制台时.我转储了$ _SERVER变量,这是cron/console的全部内容

(
   [SHELL] => /bin/sh
   [MAILTO] => *removed*
   [USER] => *removed*
   [PATH] => /usr/bin:/bin
   [PWD] => /home/*removed*
   [SHLVL] => 1
   [HOME] => /home/*removed*
   [LOGNAME] => *removed*
   [_] => /usr/local/bin/php
   [PHP_SELF] => /home/*removed*/public_html/support/cron.php
   [SCRIPT_NAME] => /home/*removed*/public_html/support/cron.php
   [SCRIPT_FILENAME] => /home/*removed*/public_html/support/cron.php
   [PATH_TRANSLATED] => /home/*removed*/public_html/support/cron.php
   [DOCUMENT_ROOT] =>
   [REQUEST_TIME] => 1300522141
   [argv] => Array
       (
           [0] => /home/*removed*/public_html/support/cron.php
       )

   [argc] => 1
)

if(!$cron->isValidIp($_SERVER['REMOTE_ADDR'])) {
    echo sprintf("[ERROR]: Your IP %s is not authorized to run scheduled tasks.  Please notify your administrator.",
        $_SERVER['REMOTE_ADDR']
    );

        // [JAS]: Test all our IPs for a wildcard match
        if(is_array($this->valid_ips))
        foreach($this->valid_ips as $mask) {
            if(empty($mask)) continue;
            if(0 == strcmp(substr($ip,0,strlen($mask)),$mask)) {
                return true;
            }

该$_SERVER['REMOTE_ADDR']变量是因为Apache的填充,在命令行中运行,这个变量将不会被设置,以及其他许多人.

此外,即使已设置,REMOTE_ADDR也将始终是运行cron的计算机的本地IP,因为您无法远程运行它.

为了保持一致性,这是使用php_sapi_name的示例

if(php_sapi_name() === 'cli') {
    // You're running locally from the CLI
} else {
    // You're running remotely, check against list of authorized ip addresses.
}

在您的情况下,您可以将您的if更改为:

if(php_sapi_name() != 'cli' && !$cron->isValidIp($_SERVER['REMOTE_ADDR'])) {
    ....
