通信交互 socket套接字 图像传输

服务端：

# hostname = socket.gethostname()
# port = 8888
# s = socket.socket()
# s.bind((hostname,port))
# s.listen()
# a,b = s.accept()
# f = open('img.jpg','wb')
# while 1:
#     image = a.recv(921600)
#     if len(image) != 0:
#         f.write(image)
#     if len(image) == 0:
#         break
