Downloaded file from storj

I uploaded a text file to my Storj bucket at a specific upload path.

Now, I want to download this file, which I uploaded, so I wrote the following lines:

// Open file
obj, err := bucket.OpenObject(ctx, “test/log.txt”)
if err != nil {
return err
}
defer errCatch(obj.Close)

// Get a reader for the entire file
r, err := obj.DownloadRange(ctx, 0, -1)
if err != nil {
    return err
}
defer errCatch(r.Close)

Now, I just want that the los.txt which I uploaded earlier gets downloaded to my present working directory.

By using ioutil, I am only able to read the file and print it.

Please guide me.

First every function is already implemented in uplink you could take examples from there. Copy

You could extend your example with

var reader io.ReadCloser
reader = r

file, err := os.Create("filename")
if err != nil {
		fmt.Println("Error creating file")
		return
	}
defer file.Close()

_, err = io.Copy(file, reader)
	if err != nil {
		return err
	}

WARNING i wrote this just down from scratch, it is untested but should write your output to a file. If this already exist it will be overwritten. You need to extend this for you needs.
