requests.exceptions.InvalidHeader: Invalid leading whitespace, reserved character(s), or returncharacter(s) in header value: ' Mozilla/5.0 (Windows NT 10.0; Win64; x64)

报这个错是因为直接从浏览器复制过来的'User-Agent'有空格

'User-Agent':' Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36'
改成这样

'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36'
就可以了
