python是否禁用自动重定向？

import urllib.request

url = "http://example.com"
req = urllib.request.Request(url, method="GET", allow_redirects=False)
response = urllib.request.urlopen(req)
print(response.getcode())  # 获取响应状态码
print(response.read())  # 读取响应内容

import requests

url = "http://example.com"
session = requests.Session()
response = session.get(url, allow_redirects=False)
print(response.status_code)  # 获取响应状态码
print(response.text)  # 读取响应内容
