作为测试的一部分，尝试检查插座是否收到了日志 因此，线程发送日志，主线程尝试在套接字处检索。
无法将收到的数据转换为日志记录
根据{{3}}尝试logging.makeLogRecord。还尝试了pickle / cPickle
import unittest

import logging
import logging.handlers
#import cPickle as pickle
def test_StringReceivedIsSameAsStringSent():
host = 'localhost'
port = 9000
stringSent = "hello world!"
stringReceived = None
log_msg = None
def sendLogToSocket(host,port, stringSent):
logger = logging.getLogger('mylogger') # to log Led Observer output over a socket
sh = logging.handlers.SocketHandler(host,port) # handler to write to socket
logger.addHandler(sh)
logger.critical(stringSent)
logger.removeHandler(sh)
sh.close()
import threading
t = threading.Thread(target=sendLogToSocket, args=(host,port,stringSent)) # socket requires 2 different ports if on the same machine
t.start() # send log in a thread
import socket
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) #INET => IPv4, STREAM => TCP
serversocket.bind((host,port)) # 'localhost' => implies only visible within the same machine
serversocket.listen(1) # accept 1 connection only
(clientsocket, address) = serversocket.accept()
stringReceived = clientsocket.recv(1024)
print 'socketlistener: string received: ', repr(stringReceived)
#obj = pickle.loads(stringReceived)
#print 'un pickling log: ', obj
#log_msg = logging.makeLogRecord(obj)
log_msg = logging.makeLogRecord(stringReceived)
print 'socketlistener: converted to log: ', log_msg
clientsocket.close()
serversocket.close()
t.join() # wait for the log thread to finish
print 'string sent: ', repr(stringSent), ' received: ', repr(stringReceived
self.assertEqual(stringSent, stringReceived)
if __name__ == "__main__":
test_StringReceivedIsSameAsStringSent()

答案 0 :(得分：0)
要求1.解压缩大小和数据，2。使用size和3. unpmarkle数据取消对未打开对象的makeLogRecord（之前错过的步骤1）
感谢python docs上的代码：logging cookbook sample和network logging sample
这里我的代码已更正（假设我们在一个socket.receive调用中得到大小和完整的消息）：
