我''ve之前碰到过这个问题，似乎(就我而言)它涉及服务器或客户端某处的缓存.客户端已完成数据的发送，但服务器尚未完成数据的接收和保存.

我通过在发送数据后在客户端添加延迟来解决了该问题.我不喜欢这种解决方案，但找不到其他解决方案.

I''ve run into that problem before and it appears that (in my case) it involved a cache either on the server or client somewhere. The client had finished sending the data, but the server had not finished receiving and saving it yet.

I solved it by adding a delay on the client side after sending the data. I didn''t like that solution, but I couldn''t find any other way to easily work around it.
