python socket编程（客户端+服务器）

python socket编程（客户端+服务器）

1. 此方案适用于 多个客户端通信，结合了线性开发，服务器能同时处理多台信息。 

2. 客户端，想要有多台客户端，大家复制一下代码，然后改一下窗口名，然后运行就可以 ：

#win.title("客户端2")  

#win.title("客户端1")

3.客户端的 userName 可以自由选取。

服务器

      import tkinter
      import socket, threading
      win = tkinter.Tk()  # 创建主窗口
      win.title('模拟服务器')
      win.geometry("400x400+200+20")
      users = {}#用户字典，也可以连接数据库
      def run(ck, ca):
       userName = ck.recv(1024)#接受客户端发送的信息以1k作为单位这里接受到的信息为byte类型
       users[userName.decode("utf-8")] = ck#解码并储存用户的信息
      #print(users)
       printStr = "" + userName.decode("utf-8") + "连接\n"#在连接显示框中显示是否连接成功
       text.insert(tkinter.INSERT, printStr)
      while True:
       rData = ck.recv(1024)#接受客户端发送的信息以1k作为单位这里接受到的信息为byte类型
       dataStr = rData.decode("utf-8")
       infolist = dataStr.split(":")#分割字符串从而得到所要发送的用户名和客户端所发送的信息
       users[infolist[0]].send((userName.decode("utf-8") + "说" + infolist[1]).encode("utf"))
      #要发送信息的客户端向目标客户端发送信息
      def start():
       ipStr = eip.get()#从输入端中获取ip
       portStr = eport.get()#从输入端中获取端口，注意端口取得时候不能被占用（可以取8080，9876，等）
       server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)#socked所准守ipv4或ipv6，和相关协议的
       server.bind((ipStr, int(portStr)))#绑定ip和端口号！！！1:注意输入的端口号是str型而这里的要传入int型
      #2:bind()的参数是一个元组的形式
       server.listen(10)#设置监听，和设置连接的最大的数量
       printStr = "服务器启动成功\n"#，是否连接成功
       text.insert(tkinter.INSERT, printStr)#显示在信息窗口中
      while True:#这里用死循环是因为模拟的服务器要一直运行
       ck, ca = server.accept()#接受所连接的客户端的信息
      # 其中ca是ip和端口号组成的元组，ck有关客户端的信息
       t = threading.Thread(target=run, args=(ck, ca))#每连接一个客户端就开启一个线程
      #其中Thread函数中的传入函数的参数也是以元组的形式
       t.start()#开启线程
      def startSever():
       s = threading.Thread(target=start)#启用一个线程开启服务器
       s.start()#开启线程
      #下面是关于界面的操作
      labelIp = tkinter.Label(win, text='ip').grid(row=0, column=0)
      labelPort = tkinter.Label(win, text='port').grid(row=1, column=0)
      eip = tkinter.Variable()
      eport = tkinter.Variable()
      entryIp = tkinter.Entry(win, textvariable=eip).grid(row=0, column=1)
      entryPort = tkinter.Entry(win, textvariable=eport).grid(row=1, column=1)
      button = tkinter.Button(win, text="启动", command=startSever).grid(row=2, column=0)
      text = tkinter.Text(win, height=4, width=30)
      labeltext = tkinter.Label(win, text='连接消息').grid(row=3, column=0)
      text.grid(row=3, column=1)
      text2 = tkinter.Text(win, height=5, width=30)
      labeltext2 = tkinter.Label(win, text='接收消息').grid(row=10, column=0)
      text2.grid(row=10, column=1)
      win.mainloop()
  
 

运行结果：

客户端1 

      import tkinter
      import socket
      import threading
      win = tkinter.Tk()
      win.title("客户端1")
      win.geometry("400x400+200+20")
      ck = None#用于储存客户端的信息
      def getInfo():
      while True:
       data = ck.recv(1024)#用于接受服务其发送的信息
       text.insert(tkinter.INSERT, data.decode("utf-8"))#显示在信息框上
      def connectServer():
      global ck
       ipStr = eip.get()
       portStr = eport.get()
       userStr = euser.get()
       client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)#socked所准守ipv4或ipv6，和相关协议的
       client.connect((ipStr, int(portStr)))#连接ip和端口号！！！1:注意输入的端口号是str型而这里的要传入int型
      #2:bind()的参数是一个元组的形式
       client.send(userStr.encode("utf-8"))
       ck = client

       sendStr = esend.get()
       sendStr = friend + ":" + sendStr
