想了解python实现简单点对点(p2p)聊天的相关内容吗,Lockeyi在本文为您仔细讲解python实现简单点对点聊天的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:python,点对点,聊天,下面大家一起来学习吧。

点对点聊天首先是基于多线程的网络编程,其次就是将每一个连接都保存为一个具有独一属性的对象并添加到连接列表中,对于每一个连接对象发送过来的信息必须要包含主要的三项内容(from,to,messages),这样当信息发送到服务器之后服务器根据to的连接对象遍历连接列表找到目标对象将信息发送给目标,目标拿到信息后就知道是谁发过来的,然后根据id号码进行回复。此实现将会继续完善,后续新加功能将会在我个人github主页展现

服务器端实现:

'''
import socketserver,json
import subprocess

connLst = []
## 连接列表,用来保存一个连接的信息(代号 地址和端口 连接对象)
class Connector(object):#连接对象类
 def __init__(self,account,password,addrPort,conObj):
 self.account = account
 self.password = password
 self.addrPort = addrPort
 self.conObj = conObj


class MyServer(socketserver.BaseRequestHandler):

 def handle(self):
 print("got connection from",self.client_address)
 register = False
 while True:
  conn = self.request
  data = conn.recv(1024)
  if not data:
  continue
  dataobj = json.loads(data.decode('utf-8'))
  #如果连接客户端发送过来的信息格式是一个列表且注册标识为False时进行用户注册
  if type(dataobj) == list and not register:
  account = dataobj[0]
  password = dataobj[1]
  conObj = Connector(account,password,self.client_address,self.request)
  connLst.append(conObj)
  register = True
  continue
  print(connLst)
  #如果目标客户端在发送数据给目标客服端
  if len(connLst) > 1 and type(dataobj) == dict:
  sendok = False
  for obj in connLst:
   if dataobj['to'] == obj.account:
   obj.conObj.sendall(data)
   sendok = True
  if sendok == False:
   print('no target valid!')
  else:
  conn.sendall('nobody recevied!'.encode('utf-8'))
  continue

if __name__ == '__main__':
 server = socketserver.ThreadingTCPServer(('192.168.1.4',8022),MyServer)
 print('waiting for connection...')
 server.serve_forever()

客户端实现:

BUFSIZ = 1024 ##缓冲区大小 1K
ADDR = (HOST,PORT)

tcpCliSock = socket(AF_INET,SOCK_STREAM)
tcpCliSock.connect(ADDR)
userAccount = None
def register():
 myre = r"^[_a-zA-Z]\w{0,}"

 return None
 password1 = input('Please input your password: ')

 return (accout,password1)

class inputdata(threading.Thread):

 while True:

  msg = input('msg>>:')
  dataObj = {'to':sendto,'msg':msg,'froms':userAccount}
  datastr = json.dumps(dataObj)
  tcpCliSock.send(datastr.encode('utf-8'))


class getdata(threading.Thread):
 def run(self):
 while True:
  data = tcpCliSock.recv(BUFSIZ)
  dataObj = json.loads(data.decode('utf-8'))
  print('{} -> {}'.format(dataObj['froms'],dataObj['msg']))


def main():
 while True:

 if regInfo:
  datastr = json.dumps(regInfo)
  tcpCliSock.send(datastr.encode('utf-8'))
  break
 myinputd = inputdata()
 mygetdata = getdata()
 myinputd.start()
 mygetdata.start()
 myinputd.join()
 mygetdata.join()


if __name__ == '__main__':
 main()
