我试图在计算机上同时作为服务器和客户端运行此代码，但出现此错误。
TypeError: a bytes-like object is required, not 'str'
我是套接字编程的新手，所以我不太确定缺少什么。我认为这是一个问题，原因是我在两台服务器上都有两个不同的端口，但我已修复并且仍然无法正常工作。
这是服务器端
import socket, select
#Function to send message to all connected clients
def send_to_all (sock, message):
#Message not forwarded to server and sender itself
for socket in connected_list:
if socket != server_socket and socket != sock :
try :
socket.send(message)
except :
# if connection not available
socket.close()
connected_list.remove(socket)
if __name__ == "__main__":
name=""
#dictionary to store address corresponding to username
record={}
# List to keep track of socket descriptors
connected_list = []
buffer =1024
port =9999
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(("localhost", port))
server_socket.listen(10) #listen atmost 10 connection at one time
# Add server socket to the list of readable connections
connected_list.append(server_socket)
print ("\33[32m \t\t\t\tSERVER WORKING \33[0m")
while 1:
# Get the list sockets which are ready to be read through select
rList,wList,error_sockets = select.select(connected_list,[],[])
for sock in rList:
#New connection
if sock == server_socket:
# Handle the case in which there is a new connection recieved through server_socket
sockfd, addr = server_socket.accept()
name=sockfd.recv(buffer)
connected_list.append(sockfd)
record[addr]=""
#print "record and conn list ",record,connected_list
#if repeated username
if name in record.values():
sockfd.send("\r\33[31m\33[1m Username already taken!\n\33[0m")
del record[addr]
connected_list.remove(sockfd)
sockfd.close()
continue
else:
#add name and address
record[addr]=name
print ("Client (%s, %s) connected" % addr," [",record[addr],"]")
sockfd.send("\33[32m\r\33[1m Welcome to chat room. Enter 'tata' anytime to exit\n\33[0m")
send_to_all(sockfd, "\33[32m\33[1m\r "+name+" joined the conversation \n\33[0m")
#Some incoming message from a client
else:
# Data from client
try:
data1 = sock.recv(buffer)
#print "sock is: ",sock
data=data1[:data1.index("\n")]
#print "\ndata received: ",data
#get addr of client sending the message
i,p=sock.getpeername()
if data == "tata":
msg="\r\33[1m"+"\33[31m "+record[(i,p)]+" left the conversation \33[0m\n"
send_to_all(sock,msg)
print ("Client (%s, %s) is offline" % (i,p)," [",record[(i,p)],"]")
del record[(i,p)]
connected_list.remove(sock)
sock.close()
continue
else:
msg="\r\33[1m"+"\33[35m "+record[(i,p)]+": "+"\33[0m"+data+"\n"
send_to_all(sock,msg)
#abrupt user exit
except:
(i,p)=sock.getpeername()
send_to_all(sock, "\r\33[31m \33[1m"+record[(i,p)]+" left the conversation unexpectedly\33[0m\n")
print ("Client (%s, %s) is offline (error)" % (i,p)," [",record[(i,p)],"]\n")
del record[(i,p)]
connected_list.remove(sock)
sock.close()
continue
server_socket.close()
这是客户端

socketobj.send(msg)

这是我遇到的错误：
