サービス:
import SocketServer # SocketServer,
class MySockServer(SocketServer.BaseRequestHandler): #
def handle(self): #handle(self) ,
print 'Got a new connection from', self.client_address
while True:
data = self.request.recv(1024) # self
if not data:break
print 'recv:', data
self.request.send(data.upper()) # self
if __name__ == '__main__': # ,
HOST = '' # ( IP ),
PORT = 50007 #Server
s = SocketServer.ThreadingTCPServer((HOST, PORT), MySockServer)
# SocketServer
s.serve_forever() #
クライアント:
import socket
HOST = '192.168.1.13'
PORT = 50007
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
while True:
user_input = raw_input('msg to send:').strip()
s.sendall(user_input)
data = s.recv(1024)
print 'Received', repr(data)
s.close()
2.Python SocketserverによるFTPプログラムサービス:
import socketserver
import struct
import json
import os
class FtpServer(socketserver.BaseRequestHandler):
coding='utf-8'
server_dir='file_upload'
max_packet_size=1024
BASE_DIR=os.path.dirname(os.path.abspath(__file__))
def handle(self):
print(self.request)
while True:

data_len=struct.unpack('i',data)[0]
head_json=self.request.recv(data_len).decode(self.coding)
head_dic=json.loads(head_json)
# print(head_dic)
cmd=head_dic['cmd']
if hasattr(self,cmd):
func=getattr(self,cmd)
func(head_dic)
def put(self,args):
file_path = os.path.normpath(os.path.join(
self.BASE_DIR,
self.server_dir,
args['filename']
))
filesize = args['filesize']
recv_size = 0
print('----->', file_path)
with open(file_path, 'wb') as f:
while recv_size < filesize:
recv_data = self.request.recv(self.max_packet_size)
f.write(recv_data)
recv_size += len(recv_data)
print('recvsize:%s filesize:%s' % (recv_size, filesize))
ftpserver=socketserver.ThreadingTCPServer(('127.0.0.1',8080),FtpServer)
ftpserver.serve_forever()
クライアント:
import socket

if connect:
try:

except:
self.client_close()
raise

def run(self):

self.socket.send(head_json_bytes)
