在python中，如何将对象从套接字发送出来？

import pickle

import socket

# 创建套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 序列化对象
data = pickle.dumps(obj)

# 发送数据
sock.send(data)

import socket
import pickle

# 创建套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 连接服务器
server_address = ('localhost', 8888)
sock.connect(server_address)

# 待发送的对象
obj = {'name': 'John', 'age': 30}

# 序列化对象
data = pickle.dumps(obj)

# 发送数据
sock.send(data)

# 关闭套接字
sock.close()
