python爬虫之浏览器User-Agent大全

爬虫时需要伪造浏览器User-Agent，可以手动准备，也可以用第三方库自动生成。

一.手动准备

这是我从真实的浏览器上复制的User-Agent，即每个版本都是真实存在过的。但不保证我的版本号是连续的，如实际发布了版本号1、2、3，可我从1升级的时候已经发布了3，自动升级时就跳过了2，也就无法记录到版本号2。不过这不影响爬虫，只是如果你想搜集绝对全面的User-Agent的话，即不遗漏每个版本，那我这个手动记录的可能不全。

版本号后面注释中的时间，只是发布当前版本时记录的，不一定代表"这是本月的第一个版本"，也可能它的前几个版本也是这个时间发布的，只是当时我没记录时间。若当前最新版本远远大于记录中的一些旧版本，可以在需要时根据时间或版本号进行筛选，只用较新一些的版本。

额外说一下快速复制User-Agent的方法：一开始我是在浏览器Network中随便点击一条请求，再从这条请求的Headers中滚好几下滚轮找到User-Agent；后来知道可以在浏览器Console中执行navigator.userAgent就行，而且输入命令时这两个词都有提示，同样可以按Tab键自动补全单词。

headers={}
headers['User-Agent']=random.choice(user_agent_pool)
print(headers)

注意：Chrome在2022年6月开始，访问网站时隐藏掉User-Agent中的详细浏览器版本号，如原来应该显示成102.0.5005.115，现在实际显示成102.0.0.0，且无论是从Network中还是Console中还是服务端实际收到的User-Agent，都不再显示具体的版本号，而是类似102.0.0.0这种，具体Chrome政策介绍。我的代码中从6月开始的Chrome的User-Agent，我还是手动写了完整的版本号，这个完整的版本号是从浏览器的"帮助-关于Google Chrome"中手动复制的。

二.第三方库自动生成

这个库叫fake-useragent，初次使用时它会从这个网址获取大量User-Agent并存入本地，以后再用时可以接着请求这个网址，也可以设置为使用本地的缓存。网址末尾是版本号，且由于某些原因这个网址无法打开，所以初次使用时会报错，我放出0.1.11版的内容，保存为fake_useragent_0.1.11.json放入本地缓存文件夹，windows在C:\Users\用户名\AppData\Local\Temp，linux在/tmp。解决报错参考链接1。

我看了下这个文件，里面的浏览器版本号过于低，如果有网站检测浏览器版本号大小(范围)的话，就可能被检测到，这也是我上面手动记录时同时记录发布时间的原因。

补充一个网站，里面也是很多低版本号的User-Agent。
