How to return a video to postman

Question

I'm doing a project of mine something like lets say youtube I've done the uploading videos part but I'm stuck on how can I playback those videos to Postman?

I've tried making the return type MultipartFile class and just returning the file but it doesn't seems to work.

@RestController
public class VideoController {
    @PostMapping(value = "/upload")
    public void uploadVideo(@RequestParam("video") MultipartFile file) throws IOException {

        byte[] bytes = file.getBytes();
        File newVideo = new File("D:\\test\\" + file.getName() + ".mp4");
        FileOutputStream fos = new FileOutputStream(newVideo);
        fos.write(bytes);
    }
}

By Postman you mean this https://www.getpostman.com/? Why do you think it can play videos? — NeplatnyUdaj, May 02 '19 at 15:03
@NeplatnyUdaj can't it? I've returned images so I though it could do the same with videos. — Uponn, May 02 '19 at 15:09
`If your API endpoint returns an image, Postman will detect and render it automatically.`. Not a word about videos. https://learning.getpostman.com/docs/postman/sending_api_requests/responses/#preview — NeplatnyUdaj, May 02 '19 at 15:21

I don't think Postman support video streaming. Regardless, in order to stream video your VideoController would need to have a GetMapping method that supports range requests which is a non-trivial coding task.

You should take a look at the community project Spring Content. This project is an abstraction over Storage and provides a range of Storage implementations including the good old Filesystem. Importantly, it also supports video streaming out of the box as this post describes.

NB: Current version of Spring Content is 0.8.0.
