Python -- 网络编程 -- Socket简单网络通信

Qt如果多线程的话，似乎会出BUG

1.服务端(server.py)

 import sys, socket, threading
 import binascii
 from PyQt4 import QtCore, QtGui

 class ListenThread(threading.Thread):
     def __init__(self, txt, server):
         threading.Thread.__init__(self)
         self.txt = txt
         self.server = server
     def run(self):
         self.txt.append('来嘛来嘛\n')
         while 1:
             try:
                 client, addr = self.server.accept()
                 self.txt.append('连接来自:{}:{}\n'.format(addr[0], addr[1]))
                 data = client.recv(1024)
                 self.txt.append('收到数据:{}\n'.format(data.decode('utf-8')))
                 client.send('I Got:'.encode('utf-8') + data)
                 client.close()
                 self.txt.append('关闭客户端\n')
             except:
                 self.txt.append('关闭连接\n')
                 break
 class ControlThread(threading.Thread):
     def __init__(self, txt):
         threading.Thread.__init__(self)
         self.txt = txt
         self.event = threading.Event()
         self.event.clear()
     def run(self):
         self.server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
         self.server.bind(('', 1051))
         self.server.listen(1)
         self.txt.append('正在等待连接\n')
         self.lsn = ListenThread(self.txt, self.server)
         self.lsn.setDaemon(True)
         self.lsn.start()
         self.event.wait()
         self.server.close()
     def stop(self):
         self.event.set()

 class MyWindow(QtGui.QWidget):
     def __init__(self):
         QtGui.QWidget.__init__(self)
         self.setWindowTitle('服务端')
         self.resize(485, 300)

         self.btn1 = QtGui.QPushButton('开始监听')
         self.btn2 = QtGui.QPushButton('停止监听')
         self.txt = QtGui.QTextEdit()

         self.grid = QtGui.QGridLayout()
         self.grid.addWidget(self.btn1, 0, 0)
         self.grid.addWidget(self.btn2, 0, 1)
         self.grid.addWidget(self.txt, 1, 0, 1, 2)
         self.setLayout(self.grid)

         self.connect(self.btn1, QtCore.SIGNAL('clicked()'), self.onBtn1)
         self.connect(self.btn2, QtCore.SIGNAL('clicked()'), self.onBtn2)
     def onBtn1(self):
         self.ctrl = ControlThread(self.txt)
         self.ctrl.setDaemon(True)
         self.ctrl.start()
     def onBtn2(self):
         self.ctrl.stop()

 app = QtGui.QApplication(sys.argv)
 mywindow = MyWindow()
 mywindow.show()
 app.exec_()

2.客户端(client.py)

 import sys, socket, threading
 import binascii
 from PyQt4 import QtCore, QtGui

 class ListenThread(threading.Thread):
     def __init__(self, txt, server):
         threading.Thread.__init__(self)
         self.txt = txt
         self.server = server
     def run(self):
         self.txt.append('来嘛来嘛\n')
         while 1:
             try:
                 client, addr = self.server.accept()
                 self.txt.append('连接来自:{}:{}\n'.format(addr[0], addr[1]))
                 data = client.recv(1024)
                 self.txt.append('收到数据:{}\n'.format(data.decode('utf-8')))
                 client.send('I Got:'.encode('utf-8') + data)
                 client.close()
                 self.txt.append('关闭客户端\n')
             except:
                 self.txt.append('关闭连接\n')
                 break
 class ControlThread(threading.Thread):
     def __init__(self, txt):
         threading.Thread.__init__(self)
         self.txt = txt
         self.event = threading.Event()
         self.event.clear()
     def run(self):
         self.server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
         self.server.bind(('', 1051))
         self.server.listen(1)
         self.txt.append('正在等待连接\n')
         self.lsn = ListenThread(self.txt, self.server)
         self.lsn.setDaemon(True)
         self.lsn.start()
         self.event.wait()
         self.server.close()
     def stop(self):
         self.event.set()

 class MyWindow(QtGui.QWidget):
     def __init__(self):
         QtGui.QWidget.__init__(self)
         self.setWindowTitle('服务端')
         self.resize(485, 300)

         self.btn1 = QtGui.QPushButton('开始监听')
         self.btn2 = QtGui.QPushButton('停止监听')
         self.txt = QtGui.QTextEdit()

         self.grid = QtGui.QGridLayout()
         self.grid.addWidget(self.btn1, 0, 0)
         self.grid.addWidget(self.btn2, 0, 1)
         self.grid.addWidget(self.txt, 1, 0, 1, 2)
         self.setLayout(self.grid)

         self.connect(self.btn1, QtCore.SIGNAL('clicked()'), self.onBtn1)
         self.connect(self.btn2, QtCore.SIGNAL('clicked()'), self.onBtn2)
     def onBtn1(self):
         self.ctrl = ControlThread(self.txt)
         self.ctrl.setDaemon(True)
         self.ctrl.start()
     def onBtn2(self):
         self.ctrl.stop()

 app = QtGui.QApplication(sys.argv)
 mywindow = MyWindow()
 mywindow.show()
 app.exec_()
