这是一个套接字聊天室，客户端可以在其中相互发送消息。我想要一种踢球功能，服务器可以踢出某些人。
我设法做到了，这样它就可以将所需的用户赶出去，但它仍然也把我赶出去，这是执行此操作的代码：
for name in keys:
if('**kick '+name) in data:
clients[name].close()
del clients[name]
found = True
我已经尝试过了：
for name in keys:
if('**kick '+name) in data:
data = data.replace('**kick '+name,'')
clients.get(name).pop
found = True
但是当我运行这段代码并尝试使用它时，我会被踢。
这是我的完整代码：
import socket, threading
host = "127.0.0.1"
port = 4000
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host,port))
s.listen()
clients = {}
print("Server is ready...")
serverRunning = True
def handle_client(conn, uname):
clientConnected = True
keys = clients.keys()
help = 'There are 3 commands in Messenger\n1**chatlist > gives you the list of the people currently online\n2**quit > To end your session and quit the server\n3**(username) sends a private message to any user you want'
while clientConnected:
try:
response = 'Number of People Online\n'
data = conn.recv(1024).decode('ascii')
found = False
if '**' not in data:
for k,v in clients.items():
if v != conn:
v.send(data.encode('ascii'))
found = True
elif '**chatlist' in data:
clientNo = 0
for name in keys:
clientNo += 1
response = response + str(clientNo) +'::' + name+'\n'
conn.send(response.encode('ascii'))
found = True
elif '**help' in data:
conn.send(help.encode('ascii'))
found = True
else:
for name in keys:
if('**'+name) in data:
data = data.replace('**'+name,'')
clients.get(name).send(data.encode('ascii'))
found = True
if('**kick '+name) in data:
clients.get(name).pop
found = True
if(not found):
conn.send('Trying to send message to invalid person.'.encode('ascii'))
except:
clients.pop(uname)
print(uname + ' has logged out')
clientConnected = False
while serverRunning:
conn,addr = s.accept()
uname = conn.recv(1024).decode('ascii')
print('%s connected to the server'%str(uname))
conn.send('Welcome to Messenger. Type **help to know all the commands'.encode('ascii'))
if(conn not in clients):
clients[uname] = conn
threading.Thread(target = handle_client, args = (conn, uname,)).start()
import socket,threading
host = "127.0.0.1"
port = 4000
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host,port))
uname = input("Enter username: ")
s.send(uname.encode('ascii'))
clientRunning = True
def echo_data(sock):
serverDown = False
while clientRunning and (not serverDown):
try:
data = sock.recv(1024).decode('ascii')
print(data)
except:
print('Server is Down. You are now Disconnected. Press enter to exit...')
serverDown = True
threading.Thread(target=echo_data, args = (s,)).start()
while clientRunning:
tempMsg = input()
data = uname + '>> ' + tempMsg
s.send(data.encode('ascii'))

您可以使用del代替.pop
注释clients.get(name).pop代码并写成del clients[name]。
您需要从除外块中删除clients.pop(uname)。就是这样。
这是代码
server.py
import socket, threading
host = "127.0.0.1"
port = 5000
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host,port))
s.listen()
clients = {}
print("Server is ready...")
serverRunning = True
def handle_client(conn, uname):
clientConnected = True
keys = clients.keys()
help = 'There are 3 commands in Messenger\n1**chatlist > gives you the list of the people currently online\n2**quit > To end your session and quit the server\n3**(username) sends a private message to any user you want'
while clientConnected:
try:
response = 'Number of People Online\n'
data = conn.recv(1024).decode('ascii')
found = False
if '**' not in data:
for k,v in clients.items():
if v != conn:
v.send(data.encode('ascii'))
found = True
elif '**chatlist' in data:
clientNo = 0
for name in keys:
clientNo += 1
response = response + str(clientNo) +'::' + name+'\n'
conn.send(response.encode('ascii'))
found = True
elif '**help' in data:
conn.send(help.encode('ascii'))
found = True
else:
for name in keys:
if('**'+name) in data:
data = data.replace('**'+name,'')
clients.get(name).send(data.encode('ascii'))
found = True
if('**kick '+name) in data:
print('Name: '+ name)
print('Client: '+ str(clients))
# clients.get(name).pop
del clients[name]
found = True
if(not found):
conn.send('Trying to send message to invalid person.'.encode('ascii'))
except:
print(uname + ' has logged out')
clientConnected = False
while serverRunning:
conn,addr = s.accept()
uname = conn.recv(1024).decode('ascii')
print('User : '+ uname)
print('%s connected to the server'%str(uname))
conn.send('Welcome to Messenger. Type **help to know all the commands'.encode('ascii'))
if(conn not in clients):
print("Conn: " + str(conn))
clients[uname] = conn
threading.Thread(target = handle_client, args = (conn, uname,)).start()
Client.py
#!/usr/bin/env python3
import socket,threading
host = "127.0.0.1"
port = 5000
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host,port))
# uname = raw_input("Enter username: ")
uname = input("Enter username: ")
print('Uname: '+ str(uname))
s.send(uname.encode('ascii'))
clientRunning = True
def echo_data(sock):
serverDown = False
while clientRunning and (not serverDown):
try:
data = sock.recv(1024).decode('ascii')
print(data)
except:
print('Server is Down. You are now Disconnected. Press enter to exit...')
serverDown = True
threading.Thread(target=echo_data, args = (s,)).start()
while clientRunning:
tempMsg = input()
data = uname + '>> ' + tempMsg
s.send(data.encode('ascii'))

clients是一本字典。因此，从根本上讲，踢特定用户意味着从客户字典中删除其凭据。所以代替
clients.get(name).pop
采用
clients.pop(name)
编辑：也不要使用for name in keys:
使用for name in list(clients):
因为，您无法在遍历字典时更改其大小。它将引发异常。但是，此代码只会将用户从词典中删除，而不会把您踢出局。除非您确实从字典中获取用户的值并使用.close（），否则不会将用户踢出。希望这会有所帮助
