没关系,我在网上找到了一些帮助代码。现在我的代码看起来像这样,以防其他人需要这个:
package main
import (
"net/http"
"text/template"
"code.google.com/p/go.net/websocket"
"fmt"
"os"
"time"
)
const address string = "localhost:9999"
func main() {
initWebsocketClient()
}
func initWebsocketClient() {
fmt.Println("Starting Client")
ws, err := websocket.Dial(fmt.Sprintf("ws://%s/ws", address), "", fmt.Sprintf("http://%s/", address))
if err != nil {
fmt.Printf("Dial failed: %s\n", err.Error())
os.Exit(1)
}
incomingMessages := make(chan string)
go readClientMessages(ws, incomingMessages)
i := 0
for {
select {
case <-time.After(time.Duration(2e9)):
i++
response := new(Message)
response.RequestID = i
response.Command = "Eject the hot dog."
err = websocket.JSON.Send(ws, response)
if err != nil {
fmt.Printf("Send failed: %s\n", err.Error())
os.Exit(1)
}
case message := <-incomingMessages:
fmt.Println(`Message Received:`,message)
}
}
}
func readClientMessages(ws *websocket.Conn, incomingMessages chan string) {
for {
var message string
// err := websocket.JSON.Receive(ws, &message)
err := websocket.Message.Receive(ws, &message)
if err != nil {
fmt.Printf("Error::: %s\n", err.Error())
return
}
incomingMessages <- message
}
}
同样正如recoba在评论中所建议的那样,这里有一个新的大猩猩示例,供寻求更好解决方案的人使用。

看看这个基于事件的客户端,超级简单:https : //github.com/rgamba/evtwebsocket
例子:
package main
import (
"fmt"
"github.com/rgamba/evtwebsocket"
"golang.org/x/net/websocket"
)
func main() {
c := evtwebsocket.Conn{
OnConnected: func(w *websocket.Conn) {
fmt.Println("Connected")
},
OnMessage: func(msg []byte) {
fmt.Printf("Received message: %s\n", msg)
},
OnError: func(err error) {
fmt.Printf("** ERROR **\n%s\n", err.Error())
},
}
// Connect
c.Dial("ws://echo.websocket.org")
c.Send([]byte("TEST"), nil)
}
