我需要对大型集合中的每个网址发出简单的标头请求,以检查它们是否仍然可用。现在我做了以下代码:
from http import client
for i, triple in enumerate(catalouge):
connection = client.HTTPConnection(triple[2].strip('http://'))
connection.request('HEAD', '/')
print(connection.getresponse().status + ' on entry ' + str(i+1))
现在catalouge
是一组包含第3个元素的所有链接,是需要检查的URL。需要.strip('http://')
部分,因为否则会收到此错误:
http.client.InvalidURL: nonnumeric port:
使用此代码后,我现在收到此错误:
Traceback (most recent call last):
[...]
connection.request('HEAD', '/')
File "/usr/lib/python3.4/http/client.py", line 1137, in request
self._send_request(method, url, body, headers)

我错过了什么吗?任何建议都将非常感激。
