go語言編寫，簡單聊天室程式 1

這是一個建立於 的文章，其中的資訊可能已經有所發展或是發生改變。

go語言網路編程，先從聊天室開始：

/** * Created by Vicky.H on 13-12-6. * eclipser@163.com */package mainimport ("fmt""net""strconv""bytes"_ "bufio"_ "strings")var m map[string]*net.Connfunc main() {m = make(map[string]*net.Conn, 10)listener ,err := net.Listen("tcp", ":8080")if err != nil {fmt.Errorf(err.Error())return}defer listener.Close()index := 0for {conn, err := listener.Accept()if err != nil {fmt.Errorf(err.Error())return}name := "使用者:" + strconv.Itoa(index)defer connCloseHandler(name, conn)m[name] = &connindex++go connHandler(name, conn)}}func connCloseHandler(name string, conn net.Conn) {conn.Close()delete(m, name)for key := range(m)  {if key != name {(*(m[key])).Write(bytes.NewBufferString(name + " 離開房間\n").Bytes())(*(m[key])).Write(bytes.NewBufferString("當前房間人數:" + strconv.Itoa(len(m)) + "\n").Bytes())}}}func connHandler (name string, conn net.Conn) {conn.Write(bytes.NewBufferString("當前房間人數:" + strconv.Itoa(len(m)) + "\n").Bytes())for key := range(m)  {if key != name {(*(m[key])).Write(bytes.NewBufferString(name + " 進入房間\n").Bytes())}}for {buf := make([]byte,1024)conn.Read(buf)msg := string(buf)conn.Write(bytes.NewBufferString("我說: " + msg).Bytes())for key := range(m)  {if key != name {(*(m[key])).Write(bytes.NewBufferString(name + " 說: " + msg).Bytes())}}}}

運行：go run main.go

測試結果
