使用SWFUpload控件上传文件，服务器端我拿到文件流后写入文件。问题是：

为什么请求一发出去,就能把文件上传到服务器，其实我只想在服务器端拿到流拿到文件流后我自己写文件。如何不让SWFUpload在服务器端写文件呢？

!!!!

要看你服务器端的代码了。。swfupload只是一个前端工具，只负责发送请求，不会操作服务器保存的。。。

我在服务器端拿到文件流以后，把文件写入到指定路径。成功了，然后发现旁边还有个文件夹，里面存了文件打开后发现也是我刚刚上传的文件。最后经过测试发现使用SWFUpload组件上传时只要已发送请求到服务器，竟管不调用我的写入文件逻辑。文件也会被写入到服务器的一个文件夹。不知
道是怎么回事。我用这个组件其实就想拿到文件流，逻辑我自己写。可是这个组件是怎么通过钱端把文件写入到服务器的呢？
