python - 使用 http.client 跟随重定向

Question

有没有办法使用http.client模块自动跟踪重定向：

def grab_url(host, path = '/'):
  class Data: pass
  result = Data()
  try:
    con = http.client.HTTPConnection(host)
    con.request('GET', path)
    response = con.getresponse()
    if response.status == 200:
      result.content = response.read().decode('utf-8')
      result.headers = response.getheaders()
  catch Exception as e:
    print(e)
  return result

只要请求返回 http 响应，上述方法就可以工作200，但我不知道如何处理重定向，例如301？

使用pyCurl我只需将其设置FOLLOWLOCATION为True：

def grab_url(host, path = '/'):
  buffer = BytesIO()
  c = pyCurl.Curl()
  c.setopt(c.FOLLOWLOCATION, True)
  c.setopt(c.URL, host + path)
  c.setopt(c.WRITEDATA, buffer)
  c.perform()
  status = c.getinfo(c.RESPONSE_CODE)
  if status == 200:
    return buffer.getvalue().decode('iso-8859-1')
