類似Go語言中的Channel通信方式的網絡服務包：Libchan

Libchan是一個超輕量級的網絡庫，它可以讓網絡服務之間的通信能夠與Go例程之間的通信渠道一樣。

• 簡單的消息傳遞
• 同步并發編程
• 嵌套，通道可以傳輸通道
</ul>

ibchan支持以下傳輸方式：

• In-memory Go channel
• Unix socket
• Raw TCP
• TLS
• HTTP2/SPDY
• Websocket

Example usage

下面是實現基本的RPC樣式的請求/響應的例子。我們忽略錯誤處理，以簡潔證明的其核心概念。

在客戶端中:

var ch libchan.Sender

// Send a message, indicate that we want a return channel to be automatically created
ret1, err := ch.Send(&libchan.Message{Data: []byte("request 1!"), Ret: libchan.RetPipe})

// Send another message on the same channel
ret2, err := ch.Send(&libchan.Message{Data: []byte("request 2!"), Ret: libchan.RetPipe})

// Wait for an answer from the first request.  Set flags to zero
// to indicate we don't want a nested return channel.
msg, err := ret1.Receive(0)

在服務器中:

var ch libchan.Receiver

// Wait for messages in a loop
// Set the return channel flag to indicate that we
// want to receive nested channels (if any).
// Note: we don't send a nested return channel, but we could.
for {
    msg, err := ch.Receive(libchan.Ret)
    msg.Ret.Send(&libchan.Message{Data: []byte("this is an extremely useful response")});
}
