var ws = require("nodejs-websocket")
var AllUserData = new Array()
// Scream server example: "hi" -> "HI!!!"
var server = ws.createServer(function (conn) {
  console.log("New connection")
  conn.on("text", function (str) {
    console.log("Received "+str)
    AllUserData.push({
      'id':str,
      'ws':conn
    })
    conn.sendText(str.toUpperCase()+"!!!")
  })
  conn.on("close", function (code, reason) {
    console.log("Connection closed")
    // 當(dāng)用戶退出的時候捕捉到退出的用戶
    for (var i=0 in AllUserData) {
      if (AllUserData[i].ws == conn) {
        console.log(AllUserData[i])
      }
    }
  })
}).listen(8001)
