(Python) 如何检查 http 响应状态

Question

有人可以告诉我如何使用 http.client 检查 HTTP 响应的状态码吗？我在 http.client 的纪录片中没有找到任何具体内容。代码如下所示：

  if conn.getresponse():
    return True #Statuscode = 200
  else:
    return False #Statuscode != 200

我的代码看起来像这样：

from urllib.parse import urlparse
import http.client, sys

def check_url(url):
  url = urlparse(url)
  conn = http.client.HTTPConnection(url.netloc)
  conn.request("HEAD", url.path)
  r = conn.getresponse()
  if r.status == 200:
    return True
  else:
    return False

if __name__ == "__main__":
  input_url=input("Enter the website to be checked (beginning with www):")
  url = "http://"+input_url
  url_https = "https://"+input_url
  if check_url(url_https):
    print("The entered Website supports HTTPS.")
  else:
    if check_url(url):
      print("The entered Website doesn't support HTTPS, but supports HTTP.")
  if check_url(url):
    print("The entered Website supports HTTP too.")

看看这里的文档，你只需要做：

r = conn.getresponse()
print(r.status, r.reason)

更新：如果您想（如评论中所述）检查 http 连接，您最终可以使用HTTPConnection并读取状态：

import http.client

conn = http.client.HTTPConnection("docs.python.org")
conn.request("GET", "/")
r1 = conn.getresponse()
print(r1.status, r1.reason)

如果网站正确配置为实施 HTTPS，则状态代码不应为 200；在此示例中，您将收到301 Moved Permanently响应，这意味着请求已重定向，在本例中重写为 HTTPS 。
