缘起
由于写了个小脚本，用于控制服务器上的访问端口 IP 白名单。其中脚本会请求多个接口返回出口的 ip 地址，后期用于设置访问 IP 白名单。
以往一直用的好好的，但是近来不知为何总是获取到了 IPV6 的地址。
于是乎，便开始了我的搜索踩坑之旅 …
答案 1 坑 1
import socket
import requests
# 设置 socket 的参数，强制使用 IPv4
socket_af = socket.AF_INET
socket_family = socket.AF_INET
# 创建请求
response = requests.get("http://example.com", socket_family=socket_af, socket_type=socket_family)
# 打印响应内容
print(response.text)
通过设置
socket.AF_INET来指定 socket 的地址族为 IPv4，创建了一个请求并指定了socket_family参数为socket.AF_INET。
原帖大概意思是说起到了上述这个作用，但是实际使用下来却提示 Session.request() got an unexpected keyword argument 'socket_family' 和Session.request() got an unexpected keyword argument 'socket_type'，并没有这两个参数。
答案 2 坑 2
import socket
import requests.packages.urllib3.util.connection as urllib3_cn
def allowed_gai_family():
"""
https://github.com/shazow/urllib3/blob/master/urllib3/util/connection.py
"""
family = socket.AF_INET
if urllib3_cn.HAS_IPV6:
family = socket.AF_INET6 # force ipv6 only if it is available
return family
urllib3_cn.allowed_gai_family = allowed_gai_family
无语，直接报错。。。

TypeError: 'AddressFamily' object is not callable答案 3 正解
requests.packages.urllib3.util.connection.HAS_IPV6 = False这是我试了三个答案当中唯一一个好使的，在初始化的时候调用，即 requests 请求之前调用。
正文完
