最近实验室要求在爬取一些论文数据，过程中遇到了不少问题，在此记录一下。

未解决的问题

https://chemistry-europe.onlinelibrary.wiley.com/doi/full/10.1002/cctc.202101625
这个网页，当我用requests去获得它的论文数据时，无论怎么设置headers和cookie，还是显示503错误，不知道是什么反爬的措施。在此把代码贴出来，期待能收获大佬的解答。

import requests
from hyper.contrib import HTTP20Adapter
url = 'https://chemistry-europe.onlinelibrary.wiley.com/doi/full/10.1002/cctc.202101625'
session = requests.session()
session.mount(url, HTTP20Adapter())
headers = {
