客户端：

# import json
# import struct
# sk = socket.socket()
# sk.connect(("127.0.0.1",8090))  #连接服务端
# buffer = 1024
# #发送文件
# head = {
#     "filename":r"员工信息表作业讲解.mp4","filepath":r'j:',"filesize":None
# 
# }
# file_path = os.path.join(head["filepath"]+head["filename"])
# filesize = os.path.getsize(file_path)
# head["filesize"] = filesize
# json_head = json.dumps(head) #字典转字符串
# bytes_head = json_head.encode("utf-8")#字符串转byets
# head_len = len(bytes_head)
# pack_len = struct.pack("i",head_len)
# sk.send(pack_len)
# sk.send(bytes_head)
# with open(file_path,"rb") as f:
