如何在Python socket 聊天室中设置踢脚功能?
How to make a kick feature in Python socket chat room?
这是一个套接字聊天室,客户端可以在其中相互发送消息。我想要一个踢球功能,服务器可以踢出某些人。
我已经成功将所需用户踢出,但它仍在将我踢出,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
我试过这个:
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 这段代码并尝试它时,我反而被踢了。
这是我的完整代码:
Server.py
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()
Client.py
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'))
clients 是一个字典。所以基本上,踢一个特定的用户意味着从客户字典中删除他的凭据。所以而不是
clients.get(name).pop
采用
clients.pop(name)
编辑:也不是使用 for name in keys:
使用 for name in list(clients):
因为,您不能在遍历字典时更改字典的大小。它会抛出异常。但是,此代码只会将用户从字典中删除,而不会将您踢出。除非您从字典中获取用户的值并使用 .close(),否则用户不会被踢出。希望这有帮助
您可以使用 del
而不是 .pop
评论 clients.get(name).pop
代码并写 del clients[name]
。
您需要从 except 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'

found = True

print('Client: '+ str(clients))
# clients.get(name).pop
del clients[name]

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()

我一直在制作一个聊天应用,对我来说最好的禁止某人的方式是
- 建立数据库
- 为人们提供用户名、密码、数字 ID
- 每当有人连接时,要求他们提供凭据。(id 可以是程序会直接给你的东西,用户可能不必给它)
- 如果想禁止某人使用数据库中的信息
- 如果他在数据库中被禁止,则关闭套接字。
