如何将日志记录添加到带有时间戳的文件到 Raspberry Pi 的 Python TCP 服务器

我的项目有点陷入困境，我迫切需要帮助。我需要一个简单的 TCP 服务器 python 代码，它具有日志记录和时间戳等功能，我可以将其用于我的 Raspberry Pi。这是我的最后一年项目。

我看过一些例子，但由于我在编写自己的脚本/代码方面没有太多经验，所以我不太确定如何去做。如果有人能够通过解释和一些示例（如果可能的话）指导我正确的方向，我将不胜感激。

我正在使用 HERCULES SETUP UTILITY ，它充当我的 TCP 客户端，而我的 Visual Studio Python 代码充当服务器。我的服务器现在可以接收客户端发送的数据，我只是似乎无法添加可以将发送的数据保存到文本文件中的日志文件。有人可以给我看一些示例或参考吗？你的帮助意义重大。到目前为止，这是我的代码：

from socket import *
import thread

BUFF = 1024 # buffer size
HOST = '172.16.166.206'# IP address of host
PORT = 1234 # Port number for client & server to recieve data
def response(key):
    return 'Sent by client'

def handler(clientsock,addr):
    while 1:
        data = clientsock.recv(BUFF) # receive data(buffer).
        print 'data:' + repr(data)   #Server to recieve data sent by client.
        if not data: break           #If connection is closed by client, server will        break and stop recieving data.
        print 'sent:' + repr(response('')) # respond by saying "Sent By Client". 



if __name__=='__main__':
    ADDR = (HOST, PORT) #Define Addr
    serversock = socket(AF_INET, SOCK_STREAM) 
    serversock.bind(ADDR) #Binds the ServerSocket to a specific address (IP address and     port number)
    serversock.listen(0)
    while 1:
        print 'waiting for connection...'
        clientsock, addr = serversock.accept()
        print '...connected from:', addr #show its connected to which addr
        thread.start_new_thread(handler, (clientsock, addr ))

要将日志记录添加到带有时间戳的文件中，您可以使用logging module:

import logging

logging.basicConfig(level=logging.INFO, 
                    filename='myserver.log', # log to this file
                    format='%(asctime)s %(message)s') # include timestamp
logging.info("some message")

如果你运行代码；你应该看到myserver.log（+/- 您的时区和当前时间）：

2013-12-24 09:20:17,739 some message

这是 TCP 服务器的完整示例，它将从客户端接收的每个行添加到前面："Sent by Client: "短语并将其发回：

#!/usr/bin/env python
import logging
import sys
from SocketServer import ThreadingTCPServer, StreamRequestHandler

info = logging.getLogger(__name__).info

class EchoLineHandler(StreamRequestHandler):
    def handle(self):
        info("handling request from %s", self.client_address)
        # prepend each line (b'\n') and send it back
        for line in self.rfile:
            self.wfile.write(b"Sent by Client: ") # assume ascii-based encoding
            self.wfile.write(line)
        info("done %s", self.client_address)

def test(ServerClass=ThreadingTCPServer, HandlerClass=EchoLineHandler):
    # configure logging
    logging.basicConfig(level=logging.INFO,
                        filename='server.log', # log to this file
                        format='%(asctime)s %(message)s') # include timestamp

    # parse command line arguments
    host, port = 'localhost', 8826
    if len(sys.argv) > 1:
        host_, separator, port_ = sys.argv[1].rpartition(":")
        port = int(port_)
        if separator: # if ":" in sys.argv[1]
            host = host_ # accept any host, including empty

    # listen for connections
    server = ServerClass((host, port), HandlerClass)
    info("Serving on %s port %s", *server.server_address)
    try:
        server.serve_forever()
    finally:
        info("quit.")

if __name__=="__main__":
    test()

如果代码保存在则运行服务器echo_line_server.py:

$ python -mecho_line_server localhost:8826 & tail -F server.log
2013-12-24 17:09:38,089 Serving on 127.0.0.1 port 8826

运行客户端：

$ echo abc | nc localhost 8826
Sent by Client: abc
