用於TCP服務器的Python日誌記錄

Question

我在爲我的python TCP服務器代碼添加日誌記錄文件時遇到了一些問題。 我看了一些例子，但由於我沒有太多的經驗來編寫我自己的腳本/代碼，我不知道如何去做這件事。如果有人能夠在正確的方向引導我解釋並儘可能舉例，我將不勝感激。

我使用的是HERCULES SETUP UTILITY，它充當我的TCP客戶端，而我的Visual Studio Python代碼充當服務器。我的服務器可以接收客戶現在發送的數據，我似乎無法添加可以將發送的數據保存爲文本文件的日誌文件。請給我一些示例或參考嗎？你的幫助意味着很多。這是到目前爲止我的代碼：

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)) 

Answer 1

這聽起來好像是你的問題會得到更好的重新表述「如何閱讀和Python中寫入文件？」。 http://docs.python.org/2.7/tutorial/inputoutput.html#reading-and-writing-files

例：

f = open('/tmp/log.txt', 'a') 

f.write('Doing something') 
do_something() 

f.write('Other stuff') 
other_stuff() 

f.write('All finished') 
f.close() 

Answer 2

在上下文中，也許這樣的事情

這是一件很好的記錄？

#!/usr/local/cpython-2.7/bin/python 

import socket 
import thread 

BUFF = 1024 # buffer size 
HOST = '127.0.0.1' 
PORT = 1234 # Port number for client & server to recieve data 
def response(key): 
    return 'Sent by client' 


def logger(string, file_=open('logfile.txt', 'a'), lock=thread.allocate_lock()): 
    with lock: 
     file_.write(string) 
     file_.flush() # optional, makes data show up in the logfile more quickly, but is slower 


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



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