python - 发送 httplib 的多个请求，引发回溯异常

Question

这是代码:

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有问题

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()

它出现了异常，但有趣的是请求成功了:

有什么建议吗？？？

在我看来，你的缓冲区已满。您的缓冲区将填充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。不确定是否没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短暂的 time.pause 来给服务器一些时间来确认接收。
