我不知道为什么会发生这种情况...客户端在出现此错误之前，可以上传大约15-30个文件（从文件夹，通过java客户端）。我正在运行Rails 2.0.2。可能事实上，我以开发模式运行sqlite作为数据库导致这个？任何帮助将不胜感激 ！
谢谢你们！
解决方案
我想我认为至少我觉得我这样做（客户端只是继续上传，无错误）。
从您上传的文件中读取数据后，您还应该关闭。谁曾想到？ ：P
I have a rails application, running in development mode ( with a sqlite database ). The application's purpose is to allow users to upload files through a java client.
If a user wants to upload a folder, all the files inside it will be recursively uploaded. If a user wants to upload a file, the file will be uploaded normally.
Here's the error I'm receiving :
IOError
in UploadedFilesController#new
closed stream

I have no clue why this happens ... the client gets to upload about 15-30 files ( from a folder, through the java client ) before this error appears. I am running Rails 2.0.2 . Could the fact that I'm running in development mode using sqlite as a database cause this ? Any help would be greatly appreciated !
Thanks guys !
解决方案
I think I've figured it out, at least I think I do ( the client just keeps on uploading now, error-free ) . After you read data from a file that you upload, you should also CLOSE it. Who would have thought? :P
这篇关于什么可能导致这个轨道ioerror封闭流？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
