你好我是python编程新手。我可以知道为什么我的服务器没有收到客户端发送的消息吗?我试图将数据从客户端发送到服务器并使服务器在控制台中显示...
Client.py
import asyncore
import socket
class Client(asyncore.dispatcher):
def __init__(self,IPAddress_Server,intServerPort):
asyncore.dispatcher.__init__(self)
self.IPHostEntry_Server = (IPAddress_Server,intServerPort)
self.create_socket(socket.AF_INET,socket.SOCK_STREAM)
self.set_reuse_addr()
self.connect(self.IPHostEntry_Server)
def handle_connect(self):
print("Successfully connected to {0}".format(self.IPHostEntry_Server))
def handle_write(self):
bytesTx = b"DDDDDDD"
self.send(bytesTx)
self.close()
client = Client("127.0.0.1", 4444)
asyncore.loop()
Server.py
import asyncore
import socket
class Server(asyncore.dispatcher):
def __init__(self,IPAddress_Server,intServerPort):
asyncore.dispatcher.__init__(self)
self.IPHostEntry_Server = (IPAddress_Server,intServerPort)
self.create_socket(socket.AF_INET,socket.SOCK_STREAM)
self.set_reuse_addr()
self.bind(self.IPHostEntry_Server)
self.listen(5)
def handle_accept(self):
pair = self.accept()
if pair is not None:
sock, addr = pair
print ('Incoming connection from %s' % repr(addr))
def handle_read(self):
bytesRx = self.recv(4)
print("%s" %bytesRx)
server = Server("127.0.0.1", 4444)
asyncore.loop()
答案 0 :(得分:1)
您的服务器接受连接,然后将它们丢弃在地板上:
def handle_accept(self):
pair = self.accept()
if pair is not None:
sock, addr = pair
print ('Incoming connection from %s' % repr(addr))
服务器套接字与服务器套接字接受的每个连接是分开的。
如果你想从连接读取字节,那么你必须做更多的工作来处理它上的读取事件。
我建议看看Twisted代替。它比asyncore更积极地维护,记录更好,功能更强大。这是一个最小的基于Twisted的示例,可以执行我认为您希望应用程序执行的操作:
tx_client.py
from twisted.internet.task import react
from twisted.internet.defer import Deferred
from twisted.internet.protocol import Protocol
from twisted.internet.endpoints import clientFromString, connectProtocol
class SendBytes(Protocol):
def __init__(self, data):
self.data = data
self.done = Deferred()
def connectionMade(self):
self.transport.write(self.data)
self.transport.loseConnection()
def connectionLost(self, reason):
self.done.callback(None)
def main(reactor, description, data):
endpoint = clientFromString(reactor, description)
connecting = connectProtocol(endpoint, SendBytes(data))
def connected(proto):
print("Successfully connected to {0}".format(proto.transport.getPeer().host))
return proto.done
connecting.addCallback(connected)
return connecting
if __name__ == '__main__':
react(main, [b"tcp:host=127.0.0.1:port=4444", b"DDDDDD"])
tx_server.py
from twisted.internet.task import react
from twisted.internet.defer import Deferred
from twisted.internet.protocol import Factory, Protocol
from twisted.internet.endpoints import serverFromString
class ReadBytes(Protocol):
def connectionMade(self):
print("Incoming connection from {}".format(self.transport.getPeer()))
def dataReceived(self, data):
print("Received {}".format(data))
def main(reactor, description):
endpoint = serverFromString(reactor, description)
endpoint.listen(Factory.forProtocol(ReadBytes))
return Deferred()
if __name__ == '__main__':
react(main, [b"tcp:interface=127.0.0.1:port=4444"])
