import struct
    
service=socket.socket()

while True:
    
    service.listen(5)

    conn,address=service.accept()
    
    print('有客户端连接进来了,地址如下',address)
    
    #获取头的内容
    
    dic_len_byte=conn.recv(4)
    
    print(dic_len_byte)

    # print(data.decode('utf8'))
    
    with open(data_name,'wb') as fw:
    
        fw.write(data)

  • client

    import socket
    
import struct

client.connect(('127.0.0.1', 8081))
    
import os
    
import json

data_head_bytes=data_head_s.encode('utf8')
    
print(data_head_bytes)
    
#把头的长度以长度为4的字节发送过去
    
head_len_bytes=struct.pack('i',len(data_head_bytes))
    
client.send(head_len_bytes)
    
client.send(data_head_bytes)
    
with open('test.py','rb') as fr:
    
    data=fr.read()
    
client.send(data)

  • 测试文件

    import json
    
ss={'name':'ypp','age':False}
    
data=json.dumps(ss) #转json字典为字符串（json格式）

print(data)
    
print(type(data))
    
data1=json.loads(data)#字符串的json格式的字典  转为字典
    
print(data1)
    
print(type(data1))
    
sss=b'kkk\n\nkk'
    
print(str(sss.decode('utf8')))
