                  问题描述

                  我的盒子里部署了一个网络服务.我想通过各种输入检查此服务的结果.这是我正在使用的代码:

                  I have a web-service deployed in my box. I want to check the result of this service with various input. Here is the code I am using:

                  import sys
                  import httplib
                  import urllib
                  
                  apUrl = "someUrl:somePort"
                  
                  fileName = sys.argv[1]
                  conn = httplib.HTTPConnection(apUrl)
                  
                  titlesFile = open(fileName, 'r')
                  
                  try:
                      for title in titlesFile:
                  
                          title = title.strip()
                          params = urllib.urlencode({'search': 'abcd', 'text': title})
                          conn.request("POST", "/somePath/", params)
                          response = conn.getresponse()
                          data = response.read().strip()
                          print data+"	"+title
                  
                          conn.close()
                  
                  finally:
                      titlesFile.close()
                  

                  此代码在打印相同数量的行后出现错误 (28233).错误信息:

                  This code is giving an error after same number of lines printed (28233). Error message:

                      raise socket.error, msg
                  socket.error: (99, 'Cannot assign requested address')
                  

                  我正在使用 Python 2.4.3.我也在做 conn.close() .但是为什么会出现这个错误呢?

                  I am using Python 2.4.3. I am doing conn.close() also. But why is this error being given?

                  推荐答案

                  这不是python问题.

                  This is not a python problem.

                  在 linux 内核 2.4 中,临时端口范围是从 32768 到 61000.因此可用端口数 = 61000-32768+1 = 28233.据我了解,因为所讨论的 Web 服务非常快(<5ms实际上)因此所有端口都用完了.程序必须等待大约一两分钟才能关闭端口.

                  In linux kernel 2.4 the ephemeral port range is from 32768 through 61000. So number of available ports = 61000-32768+1 = 28233. From what i understood, because the web-service in question is quite fast (<5ms actually) thus all the ports get used up. The program has to wait for about a minute or two for the ports to close.

                  我所做的是统计 conn.close() 的数量.当数字为 28000 时,等待 90 秒并重置计数器.

                  What I did was to count the number of conn.close(). When the number was 28000 wait for 90sec and reset the counter.
