为什么在关闭第一个连接后,以下服务器代码似乎也无法接受与客户端的新连接?
def bindPort(port):
global return_response
serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
serverSocket.bind(('', port))
except:
print("Cannot bind to port. Error: " + str(sys.exc_info))
serverSocket.listen(2)
print("The server is ready to receive")
count = 0
while True:
connectionSocket, addr = serverSocket.accept()
count += 1
print("Accepted {} connections so far.".format(count))
print('Connection established from {}'.format(addr))
while True:
sentence = connectionSocket.recv(1024)
if not sentence:
print("Empty")
break
print(sentence)
#parseIncomingRequest(sentence.decode())
print(return_response)
connectionSocket.send(return_response.encode())
return_response = ''
print("Closing loop")
connectionSocket.close()
我很抱歉没有正确阅读问题
1)在使用前声明返回响应变量
2)如果要接受其他连接,请跳出第二个while循环。在问题中,您说关闭套接字后没有任何连接被接受,但是要关闭套接字,您必须跳出第二个while循环。或者我认为您应该删除第二个循环。
3)如果您想继续监听套接字并仍然能够接收其他连接,请使用线程模块
def bindPort(port):
global return_response
serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
serverSocket.bind(('', port))
except:
print("Cannot bind to port. Error: " + str(sys.exc_info))
serverSocket.listen(2)
print("The server is ready to receive")
count = 0
while True:
connectionSocket, addr = serverSocket.accept()
count += 1
print("Accepted {} connections so far.".format(count))
print('Connection established from {}'.format(addr))
sentence = connectionSocket.recv(1024)
if not sentence:
print("Empty")
break
print(sentence)
#parseIncomingRequest(sentence.decode())
return_response = ''
print(return_response)
connectionSocket.send(return_response.encode())
connectionSocket.shutdown(socket.SHUT_RDWR)
connectionSocket.close()
4),或者如果您想保留循环以进一步修改
import socket
def bindPort(port):
global return_response
serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
serverSocket.bind(('', port))
except:
print("Cannot bind to port. Error: " + str(sys.exc_info))
serverSocket.listen(2)
print("The server is ready to receive")
count = 0
while True:
connectionSocket, addr = serverSocket.accept()
count += 1
print("Accepted {} connections so far.".format(count))
print('Connection established from {}'.format(addr))
while True:
sentence = connectionSocket.recv(1024)
if not sentence:
print("Empty")
break
print(sentence)
#parseIncomingRequest(sentence.decode())
return_response = 'a'
print(return_response)
connectionSocket.send(return_response.encode())
break
print("Closing loop")
connectionSocket.shutdown(socket.SHUT_RDWR)
connectionSocket.close()
