Haskell将套接字绑定到特定的IP

Haskell网络包中

bindSocket使用HostAddress和HostAddress6

其定义为：

-- | Network byte order.
type HostAddress = Word32

-- | Host byte order.
type HostAddress6 = (Word32, Word32, Word32, Word32)

>我如何从123.123.123.123转到Word32？
>如何从IPv6字符串转到(Word32,Word32,Word32,Word32)？

最佳答案 使用
getAddrInfo：

getAddrInfo :: Maybe AddrInfo -> Maybe HostName -> Maybe ServiceName -> IO [AddrInfo]

Resolve a host or service name to one or more addresses. The AddrInfo values that this function returns contain SockAddr values that you can pass directly to connect or bindSocket.

This function is protocol independent. It can return both IPv4 and IPv6 address information.
