Question

我既有服务器又有客户端，我正尝试通过套接字从客户端到服务器发送一个类对象，该类对象在服务器I中包含一个具有2个用户名的列表和一个具有列表2长度的变量。可以成功访问给我2个的ctotalusers，但是userslist给我[]为什么用户不见了？

客户

import socket, pickle, json

def create_send_users(i, y, k):
    msg = {'i': i, 'users': y, 'k': k}
    return json.dumps(msg)


class CaUsers(object):
    ctotalusers = None 
    userslist = []


users = CaUsers()
users.userslist.append("bob")
users.userslist.append("alice")
users.ctotalusers = len(users.userslist)


a_users = pickle.dumps(users)

msg = create_send_users("i", a_users, "k")

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 7038))
s.send(msg)

服务器

import socket, pickle, json, sys


class CaUsers(object):
    ctotalusers = None 
    userslist = []



HOST = '127.0.0.1'  
PORT = 7038

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print('# Socket created')

# Create socket on port
try:
    s.bind((HOST, PORT))
except socket.error as msg:
    print('# Bind failed. ')
    sys.exit()

print('# Socket bind complete')

# Start listening on socket
s.listen(10)
print('# Socket now listening')

# Wait for client
conn, addr = s.accept()
print('# Connected to ' + addr[0] + ':' + str(addr[1]))

# Receive data from client
while True:     
    data = conn.recv(4096)
    if data:
        users =  pickle.loads(json.loads(data)["users"])
        print users.ctotalusers # correct gives me 2 
        print users.userslist # wrong gives me []


s.close()

访问通过套接字从客户端发送到服务器的类对象数据
