本文实例讲述了golang基于websocket实现的简易聊天室。，具体如下：
先说点无关的,最近忙于工作没有更新博客,今天休息顺便把golang websocket研究了一下,挺好玩的,写了一个聊天室,分享给大家.
websocket包 : code.google.com/p/go.net/websocket
文档 : http://go.pkgdoc.org/code.google.com/p/go.net/websocket
首先安装websocket包
go get code.google.com/p/go.net/websocket
下来就是聊天室代码了,呵呵
golang websocket 聊天室
package main
import (
"fmt"
"io"
"bufio"
"net/http"
"code.google.com/p/go.net/websocket"
"container/list"
)
var connid int
var conns *list.List
func ChatroomServer(ws *websocket.Conn) {
defer ws.Close()
connid++
id := connid
fmt.Printf("connection id: %dn", id)
item := conns.PushBack(ws)
defer conns.Remove(item)
name := fmt.Sprintf("user%d", id)
SendMessage(nil, fmt.Sprintf("welcome %s joinn", name))
r := bufio.NewReader(ws)
for {
data, err := r.ReadBytes('n')
if err != nil {
fmt.Printf("disconnected id: %dn", id)
SendMessage(item, fmt.Sprintf("%s offlinen", name))
break
}
fmt.Printf("%s: %s", name, data)
SendMessage(item, fmt.Sprintf("%st> %s", name, data))
}
}
func SendMessage(self *list.Element, data string) {
// for _, item := range conns {
for item := conns.Front(); item != nil; item = item.Next() {
ws, ok := item.Value.(*websocket.Conn)
if !ok {
panic("item not *websocket.Conn")
}
if item == self {
continue
}
io.WriteString(ws, data)
}
}
// 网页客户端
func Client(w http.ResponseWriter, r *http.Request) {
