Python http服务器在2个请求后停止响应

我正在从网页上的表单向http服务器发送http post数据，前两个请求工作正常，但大多数情况下，当我发送第三个请求时，它不会收到请求 但是，在某些情况下，我确实注意到服务器在第二次请求时也没有收到请求，但这种情况并不经常发生，在第三次请求时，它会更频繁地导致问题

当我发送第一个请求时，它会立即接收并处理数据，在第二个请求时，它也会这样做，但在第三次请求时，它没有收到任何内容，网页继续显示加载标志，几秒钟后，网页给出错误信息，即可以访问该网站，并且123.12.12.12响应时间过长

这是代码

你能把你发送的请求包括在内吗？您在浏览器/curl中具体做什么？这是一个简单的http post请求，我有一个简单的HTML表单，一旦用户输入数据并单击提交按钮，表单数据将以这种格式“key1=abc&key2=123&key3=hjkl&key4=asdf&key5=2”发送到服务器。您能包含您发送的请求吗？您在浏览器/curl中具体做什么？这是一个简单的http post请求。一旦用户输入数据并单击提交按钮，我就有一个简单的HTML表单，然后表单数据以这种格式发送到服务器“key1=abc&key2=123&key3=hjkl&key4=asdf&key5=2”
