r.Message("error", err.Error())
r.Success(false)
return
}

r.Message("error", err.Error())
r.Success(false)
return
}

return
}示例2: set
// set sets the contents of a file.
func (f *File) set(fs testfs.FileSystem, r core.ResponseWriter) {
var (
file testfs.File
err error
)
// If we have a valid checksum for the input data and the file exists, read it
// and avoid modifying the file if possible.
