我们从Python开源项目中，提取了以下45个代码示例，用于说明如何使用_socket.getaddrinfo()。
def getaddrinfo(host, port, family=0, type=0, proto=0, flags=0): """Resolve host and port into list of address info entries. Translate the host/port argument into a sequence of 5-tuples that contain all the necessary arguments for creating a socket connected to that service. host is a domain name, a string representation of an IPv4/v6 address or None. port is a string service name such as 'http', a numeric port number or None. By passing None as the value of host and port, you can pass NULL to the underlying C API. The family, type and proto arguments can be optionally specified in order to narrow the list of addresses returned. Passing zero as a value for each of these arguments selects the full range of results.
