在Cronjob（Crontab）中使用会话 [英] Use Session in Cronjob (Crontab)

问题描述

您可以在cronjob中使用会话吗？

我使用的脚本是：

  session_start（）; 
 
 if（empty（$ _ SESSION ['startwert']））{$ startwert = 0;} 
 else {$ startwert = $ _SESSION ['startwert'];} 
 
 if（empty（$ _ SESSION ['zielwert']））{$ zielwert = 10000;} 
 else {$ zielwert = $ _SESSION ['zielwert'];} 
 
 
 .... 
 
 
 $ _SESSION ['startwert'] = $ zielwert; 
 $ _SESSION ['zielwert'] = $ zielwert + 10000; 
 echoStartwert：。$ _ SESSION ['startwert']。< br>; 
 echoZielwert：。$ _ SESSION ['zielwert']。< br>; 
 

但是Cron总是开始将startwert设置为10000，将zielwert设置为20000，

$ b pre> / usr / bin / wget -O - http://mydomain.com/script.php


$

解决方案

如果你通过 wget 从cron调用PHP脚本，使用 - save-cookies 选项;如果通过 curl ，请使用 - cookie-jar 。 （如果你通过 php -f [...] 或类似的方式调用PHP脚本，那么你首先需要通过改为

例如：

  wget --load-cookies / tmp / cron-session-cookies --save-cookies / tmp / cron-session-cookies --keep-session -cookies [...] 
  

或

  curl -b --cookie-jar / tmp / cron-session-cookies [...] 
  
 
 
  wget 默认情况下不保存会话cookie，因此您需要它，因此 -keep-session-cookies 选项;  curl 默认情况下保存它们，所以所有必要的是 -b 启用Cookie和 --cookie-jar 告诉 curl 在哪里可以找到它们。在任何情况下，用您已经传递给程序的任何选项和参数替换 [...] ，并调整cookie jar文件的位置。 
 
Hi is it possible to use sessions in a cronjob?

The Script I use is:
session_start();

if(empty($_SESSION['startwert'])){$startwert = 0;}
else {$startwert = $_SESSION['startwert'];}

if(empty($_SESSION['zielwert'])){$zielwert = 10000;}
else {$zielwert = $_SESSION['zielwert'];}


....


$_SESSION['startwert'] = $zielwert;
$_SESSION['zielwert'] = $zielwert + 10000;
echo "Startwert: ".$_SESSION['startwert']."<br>";
echo "Zielwert: ".$_SESSION['zielwert']."<br>";
But the Cron allways start set "startwert" to 10000 and "zielwert" to 20000 and it does not increase the values.



Ok now I have tried this.
/usr/bin/wget -O - http://mydomain.com/script.php
But the cron starts allways with 10000 and 20000. Any ideas?
解决方案
If you're invoking the PHP script from cron via wget, use the --save-cookies option; if via curl, use --cookie-jar. (If you're invoking the PHP script via php -f [...] or similar, then you'll first need to invoke it via wget or curl instead.)

For example:
wget --load-cookies /tmp/cron-session-cookies --save-cookies /tmp/cron-session-cookies --keep-session-cookies [...]
or 
curl -b --cookie-jar /tmp/cron-session-cookies [...]
wget by default doesn't save session cookies, which you want it to do, hence the --keep-session-cookies option; curl by default does save them, so all that's necessary is -b to enable cookies and --cookie-jar to tell curl where to find them. In either case, replace the [...] with whatever options and arguments you're already passing to the program, and adjust the location of the cookie jar file to taste.
