Question

我有以下代码，它假定要下载文件。

print('getting:'+url)
resp = requests.get(url, headers=headers,cookies=CUSTOM_COOKIE, params=param,stream=True,timeout=20)

但在下载时会不断出现以下错误

Traceback (most recent call last):

我想捕获此错误，我什至尝试了以下操作，但仍未捕获到异常

try:
    resp = requests.get(url, headers=headers,cookies=CUSTOM_COOKIE, params=param,stream=True,timeout=20)
except:
    print('exceptions here')

有人知道如何在这里捕获此异常吗？谢谢

请求达到超时处理
