Article Introduction：Using Python language can help everyone learn Python better. The function provided by urllib is to use programs to perform various HTTP requests. If you want to simulate a browser to complete a specific function, you need to disguise the request as a browser. The method of camouflage is to first monitor the requests sent by the browser, and then camouflage them based on the browser's request header. The User-Agent header is used to identify the browser.
