我正在创建一个基于服务器的客户端聊天客户端,每次设置服务器和客户端时,服务器都会一直监听连接,当客户端尝试连接时,会出现此错误[WinError 10054] An existing connection was forcibly closed by the remote host
,但是服务器仍然监听连接。我正在使用python版本3.6.1
脚本
import socket
import threading
clients = []
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
mode = input("Enter 1 for server mode and enter 2 for client mode")
if mode == "1":
def get_ip():
try:
stest = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
stest.connect(('10.255.255.255', 1))
IP = stest.getsockname()[0]
except:
IP = '127.0.0.1'
finally:
stest.close()
return IP
print("IP: " + get_ip())
s.bind((get_ip(), 7999))
s.setblocking(0)
print("Waiting for connection")
while True:
try:
data, addr = s.recvfrom(1024)
if data.decode() == "Quit":
quitmsg = str(addr) + " has quit the chat."
clients.remove(addr)
for client in clients:
s.sendto(quitmsg.encode("utf-8"), client)
break
elif data:
print(data)
if addr not in clients:
clients.append(addr)
print(clients[0])
for client in clients:
print(client)
s.sendto(data, client)
except:
pass
s.close()
elif mode == "2":
while True:
try:
ip = input("Enter in an ip address")
socket.inet_aton(ip)
except socket.error:
print("Invalid IPv4 address")
continue
while True:
try:
port = int(input("Enter in port number"))
except ValueError:
print("Invalid Port Number")
continue
break
addr = (ip, port)
break
s.connect(addr)
def recvmsg():
while True:
data = s.recv(1024)
print(data)
if data:
print(data.decode())
recv = threading.Thread(name="recvmsg", target=recvmsg)
recv.daemon = True
recv.start()
while True:
string = input(">>")
s.send(string.encode("utf-8"))
if str(string) == "Quit":
break
s.close()
print("Disconnected from chat")
Server Waiting For connection even after client can't connect
答案 0 :(得分:0)
如果您的服务器不在本地网络上,请确保端口7999已打开并在其接入点上转发。否则,路由器将丢弃数据包。如果它在您的本地网络上,仍然尝试转发。同样根据https://www.speedguide.net/port.php?port=7999端口已经被蠕虫使用,所以可能永久关闭在另一个网络上?不太可能但可能。
