Python socket 模块，AI_V4MAPPED 实例源码

我们从Python开源项目中，提取了以下2个代码示例，用于说明如何使用socket.AI_V4MAPPED。

def test_v4mapped(self):
        greendns.resolve = _make_mock_resolve()
        greendns.resolve.add('example.com', '1.2.3.4')
        res = greendns.getaddrinfo('example.com', 80,
                                   socket.AF_INET6, 0, 0, socket.AI_V4MAPPED)
        addrs = set(ai[-1] for ai in res)
        assert addrs == set([('::ffff:1.2.3.4', 80, 0, 0)])
