Upload file with Retrofit 2

Question

I trying to do that a few days, and I really did everything.. Here is how request looks in Postman:

I am sure, that all GET parameters were writing correctly.

Answer 1

I spent a lot of time to search, how to send a file as byte-stream because all answers in web explain upload via RequestBody, but it's not working for my case. So, here is the solution:

InputStream in = new FileInputStream(file);
    byte[] buf = new byte[in.available()];
    while (in.read(buf) != -1) ;
    RequestBody requestBodyByte = RequestBody
            .create(MediaType.parse("application/octet-stream"), buf);
    String content_disposition = "attachment; filename=\"" + fileName + "\"";

    //GET parameters
    Map params = new HashMap();
    params.put("inspectionUUID", inspectionUUID);
    params.put("noteUUID", noteUUID);
    params.put("attachmentUUID", attachmentUUID);
    params.put("noteType", noteType);
    params.put("modifiedTime", modifiedTime);

    Call call = service.upload(access_token, content_disposition, requestBodyByte, params);

Interface:

 @POST("api/MediaFiles/AddMediaFile")
    Call upload(
            @Header("Authorization") String authorization,@Header("Content-Disposition") String content_disposition, @Body RequestBody photo,
            /* GET params */ @QueryMap Map params
    );
