udp协议的编码及时间同步机制,颜色字体编码

服务器::

 import socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# sk.bind(('192.168.19.30',9090))
# while   True:
#     msg_r,addr=sk.recvfrom(1024)
#     print(addr,msg_r.decode('utf-8'))
#     s=input('>>>>')
#     sk.sendto(s.encode('utf-8'),addr)
# sk.close()

# import socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# sk.bin(('127.0.0.1',9090))
# while 1:
#     ret,addr=sk.recvfrom(1024)#接受来自哪里的消息
#     ret=ret.decode('utf-8')
#     print(ret)
#     if ret=='q':
#         continue
#     s=input('>>>')
#     sk.sendto(a.encode('utf-8'),addr)
#     if s=='q':
#         break
# sk.close()

# import socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# sk.bind(('127.0.0.1',9090))
# while 1:
#     ret,addr=sk.recvfrom(1024)
#     ret=ret.decode('utf-8')
#     print(ret)
#     if ret=='q':
#         continue
#     a=input('>>>')
#     sk.sento(a.encode('utf-8'),addr)
#     if a=='q':
#         break
# sk.close()

# import socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# sk.bind(('127.0.0.1',9090))
# while 1:
#    ret,addr=sk.recvfrom(1024)

#    sk.sendto(s.encode('utf-8'),addr)

对应服务器的客户端:::

import  socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# while 1:
#     a=input('>>>>>')
#     if a=='q':
#         break
#     sk.sendto(a.encode(),('127.0.0.1',9090))
#     msg_r,addr=sk.recvfrom(1024)
#     print(msg_r.decode('utf-8'))
# sk.close()

# import socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# while 1:
#     a=input('>>>')
#     sk.sendto(a.encode('utf-8'),('127.0.0.1',9090))
#     if a=='q':
#         break
#     ret,addr=sk.recvfrom(1024)
#     ret=ret.decode('utf-8')
#     print(ret)
#     if ret=='q':
#         break
# sk.close()

# import socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# while 1:
#     a=input(">>>")
#     sk.sendto(a.encode('utf-8'),('127.0.0.1',9090))#发送给谁一条消息
#     if a=='q':
#         break
#     ret,addr=sk.recvfrom(1024)
#     ret=ret.decode('utf-8')
#     print(ret)
#     if ret =='q':
#         break
# sk.close()

# import socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# while 1:
#     a=input('>>>')
#     sk.sendto(a.encode('utf-8'),('127.0.0.1'))
#     if a =='q':
#         break
#     ret,addr=sk.recvfrom(1024)
#     ret=ret.decode('utf-8')
#     print(ret)
#     if ret=='q':
#         break
# sk.close()


带颜色字体,,,客户端编码

带颜色的udp协议编码
# # import socket
# # sk=socket.socket(type=socket.SOCK_DGRAM)
# # name=input('输入你的名字')
# # while 1:
# #     a=input('>>>')
# #     a=name+':'+a
# #     sk.sendto(a.encode('utf-8'),('127.0.0.1',9090))
# #     if a =='q':
# #         break
# #     ret,addr=sk.recvfrom(1024)
# #     ret=ret.decode('utf-8')
# #     print(ret)
# #     if ret=='q':
# #         break
# # sk.close()
# 
# # import socket
# # sk=socket.socket(type=socket.SOCK_DGRAM)
# # name=input('请输入你的名字')
# # while 1:
# #     a=input('>>>')
# #     a=name+':'+a
# #     sk.sendto(a.encode('utf-8'),('127.0.0.1',9090))
# #     if a=='q':
# #         break
# #     ret,addr=sk.recvfrom(1024)
# #     ret=ret.decode('utf-8')
# #     print(ret)
# #     if ret=='q':
# #         break
# # sk.close()
带颜色字体,服务器编码

 带颜色的服务器代码:
# import socket
# sk=socket.socket(type=socket.SOCK_DGRAM)
# sk.bind(('127.0.0.1',9090))
# dic={'alex':'33[0;33;42m','wuse':'33[0;35;40m'}
# while 1:
#     ret,addr=sk.recvfrom(1024)#接收消息
#     ret=ret.decode('utf-8')  #转换格式
#     #对于ret通过分割获取name,再去掉name左右两边的空格.
#     name=ret.split(':')[0].strip()
#     color=dic.get(name,'')#获取字典中name所对应的颜色值
#     print('%s%s 33[0m' %(color ,ret))
#     if ret=='q':
#         continue
#     a=input('>>>')
#     sk.sendto(a.encode('utf-8'),addr)
#     if a=='q':
#         break
# sk.close()

# import socket
# # sk=socket.socket(type=socket.SOCK_DGRAM)
# # sk.bind(('127.0.0.1',9090))
# # dic={'alex':'33[0;31;41m','wuse':'33[0;32;39m'}
# # while 1:
# #     ret,addr=sk.recvfrom(1024)
# #     ret=ret.decode('utf-8')
# #     name=ret.split(':')[0].strip()
# #     color=dic.get(name,'')
# #     print('%s%s 33[0m'%(color,ret))
# #     if ret=='q':
# #         continue
# #     a=input('>>')
# #     sk.sendto(a.encode('utf-8'),addr)
# #     if a=='q':
# #         break
# # sk.close()
时间同步机制服务器编码

import socket
# import time
# sk=socket.socket(type=socket.SOCK_DGRAM)
# sk.bind(('127.0.0.1',9090))
# while 1:
#     tm_format,addr=sk.recvfrom(1024)
#     tm_format=tm_format.decode('utf-8')
#     local_tm=time.strftime(tm_format)#获取对应格式的当前时间
#     sk.sendto(local_tm.encode('utf-8'))
# sk.close()

# import socket

#     local_tm=time.retftime(ret)
#     sk.sendto(local_tm.encode('utf-8'),addr)
