用户代理:Google Web 预览版(Bot 或 Not) [英] Useragent: Google Web Preview (Bot or Not)

问题描述

我用来从真实用户中过滤机器人的方法之一是检查用户代理.检测后我阻止了他们正在使用的 IP.我看到很多访问者在他们的用户代理中嵌入了Google Web Preview"(示例):

One of the methods I use to filter bots from real users is checking the useragent. After detection I block the IP they are using. I'm seeing quite a lot of visitors coming in with 'Google Web Preview' embedded in their useragent (example):

mozilla/5.0 (x11; linux x86_64) applewebkit/537.36 (khtml, like gecko; google 
web preview) chrome/41.0.2272.118 safari/537.36

当我检查与此用户代理相关的 IP 地址时，它们似乎与 Google 无关.它们都只是来自世界各地的家庭 IP 地址.当我在我的网站上关注用户时，我注意到他的用户代理在继续浏览我的网站时立即更改为:

When I check the IP addresses related to this useragent, they don't seem to be related to Google. They are all just household IP addresses coming from all over the world. When I follow the user on my website I notice his useragent changes to as soon as it continues to browse my site:

mozilla/5.0 (ipad; cpu os 10_3_3 like mac os x) applewebkit/602.1.50 (khtml, 
like gecko) gsa/33.0.164895372 mobile/14g60 safari/602.1

问题:这是机器人还是 Google 使用访问者生成预览?IP 的行为就像普通用户一样(例如，点击链接，被 robots.txt 阻止)

Question: is this a bot or is Google using a visitor to generate a preview? The IP is behaving just like a regular user would (e.g. clicking on links, blocked by robots.txt)

谢谢！

推荐答案

当您在 chrome 中打开一个新标签页时，Google 搜索输入下方会出现一些访问量最大的链接.

When you open in chrome a new tab there are some most visited links below the google search input.

生成预览图像以便加载网页，并且在加载网页时用户代理包含Google Web Preview"

That preview images are generated so that the web page is loaded, and when the web page is loaded the user agent contains the "Google Web Preview"

所以我会说它是一个机器人.

So i would say it is a bot.
