使用python fake-useragent

安装

https://github.com/hellysmile/fake-useragent

pip install fake-useragent

使用

from fake_useragent import UserAgent
ua = UserAgent()

ua.ie
# Mozilla/5.0 (Windows; U; MSIE 9.0; Windows NT 9.0; en-US);
ua.msie
# Mozilla/5.0 (compatible; MSIE 10.0; Macintosh; Intel Mac OS X 10_7_3; Trident/6.0)'
ua['Internet Explorer']

使用nodejs nodejs-fake-useragent

这里推荐fake-useragent的移植版, 需要注意的是,当前版本有个BUG,需要先去创建个文件夹

cd ./lib/scraper; mkdir cache;

https://github.com/seekersoftec/nodejs-fake-useragent

const UserAgent = require("./index");

async function doSomething() { let uas = await UserAgent("safari"); console.log(uas); }

OR

async function doSomething() { let browserList = ["chrome", "opera"]; let uas = await UserAgent(browserList); console.log(uas); }

OR

async function doSomething() { let uas = await UserAgent(); console.log(uas); }

去网站自己抓取

号称有5200多万 https://developers.whatismybrowser.com/useragents/explore/software_type_specific/web-browser/

xpath 提取

//*[@id="content"]/table/tbody/tr[*]/td[1]/a
