发送多个httplib请求，引发回溯异常答案

【问题标题】：Sending mutlitple requests of httplib, raising traceback exceptions发送多个httplib请求，引发回溯异常
【发布时间】：2011-11-02 14:57:58
【问题描述】：

代码如下：

conn = httplib.HTTPConnection("127.0.0.1:8000")
conn.request("POST", "/api/job/", some_params, headers)
conn.close()

向服务器发送请求没问题

但如果我使用循环例如：

for i in range(n):
   conn = httplib.HTTPConnection("127.0.0.1:8000")
   conn.request("POST", "/api/job/", some_params, headers)
   conn.close()

它引发了一个异常，但有趣的是请求成功：

有什么建议吗？？？

【问题讨论】：

只是第一个请求成功进入循环？？还是所有的请求？您使用的是单线程开发服务器吗？

【解决方案1】：

在我看来，您的缓冲区已满。您的缓冲区将填满您发出的任何网络请求，然后在服务器确认收到数据时清除。不确定是否有更好的方法来执行此操作，但您可以尝试通过在循环中执行简短的 time.pause 给服务器一些时间来确认收到。
