easily manipulate the URL# the URL can be constructed into a Request object first and passed into the urlopen #Request The meaning of existence is to facilitate the passing of some information at the time of the request, while urlopen does not8. because urlopen () is not supported for advanced features of some HTTP, we can use the Urllib.request.build_opener () method if we want to modify the header. Of course, you can also use Urllib.request.Request () to implement browser simulations. Focus
