我想删除重复的x.raise_for_status()行：
x = requests.get(url1)
x.raise_for_status()
y = requests.delete(url2)
y.raise_for_status()
z = requests.post(url3,data={'foo': 'bar'})
z.raise_for_status()
如何自动调用raise_for_status()？
解决方法
使用钩子创建会话：
session = requests.Session()
session.hooks = {
'response': lambda r,*args,**kwargs: r.raise_for_status()
}
x = session.get(url1)
y = session.delete(url2)
z = session.post(url3,data={'foo': 'bar'})
