推荐答案

David，文件有多大?

没有看到错误，很可能是您尝试上传的文件超出了允许的范围(默认情况下).

服务器正在运行什么，并且要发布到什么位置?您看到错误了吗?在服务器日志中如何?

干杯.

David, how big is the file?

Without seeing the error, it''s likely that you are trying to upload a bigger file than is allowed (by default).

What is the server running, and what are you POSTing to? Is there an error that you see? How about in the server logs?

Cheers.
