python使用socket向客户端发送数据的方法

import socket, sysport = 55555host = 'localhost'data = "test" * 10485760 # 40MB of datas = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.connect((host, port))byteswritten = 0while byteswritten < len(data):  startpos = byteswritten  endpos = min(byteswritten + 1024, len(data))  byteswritten += s.send(data[startpos:endpos])  sys.stdout.write("Wrote %d bytes/r" % byteswritten)  sys.stdout.flush()s.shutdown(1)print "All data sent."while 1:  buf = s.recv(1024)  if not len(buf):    break  sys.stdout.write(buf)
