如何阻止bot在PHP中增加文件下载计数器? [英] How do I stop bots from incrementing my file download counter in PHP?

问题描述

当用户单击链接以在我的网站上下载文件时，他们会转到此PHP文件会为该文件增加一个下载计数器，然后header()将它们重定向到实际文件.我怀疑机器人正在跟踪下载链接，但是，下载次数不正确.

When a user clicks a link to download a file on my website, they go to this PHP file which increments a download counter for that file and then header()-redirects them to the actual file. I suspect that bots are following the download link, however, so the number of downloads is inaccurate.

• 如何让机器人知道他们不应该点击链接?
• 有没有办法检测大多数机器人?
• 是否有更好的方法来计算文件的下载次数?

并非所有的机器人都尊重它，但是大多数机器人都尊重它.如果您确实想防止通过漫游器进行访问，请将其链接设为POST而不是GET.漫游器不会遵循POST网址. (即，使用一个小的表格将其发布回该网站，该网站会将您带到相关的网址.)

Not all bots respect it, but most do. If you really want to prevent access via bots, make the link to it a POST instead of a GET. Bots will not follow POST urls. (I.E., use a small form that posts back to the site that takes you to the URL in question.)
