I see in the example script: ``` auth.Use(authMiddleware.MiddlewareFunc()) { auth.GET("/hello", helloHandler) auth.GET("/refresh_token", authMiddleware.RefreshHandler) } ``` when use refresh_token,first to validate token in the authMiddleware.MiddlewareFunc()? Maybe that's the reason.

I wrote some script to merge the file chunks that have uploaded ,then I found the final merged file can not be unzipped (user upload one zip file), maybe upload...

Actually I use windows ^^ Last night I use this lib on mac,compress and decompress file is all ok,but I cannot use xz command to decompress the compressed file,xz command...

那要如何修改呢？
