Retrofit 2 file down/upload

Question

I\'m trying to down/upload a file with retrofit 2 but can\'t find any tutorials examples on how to do so. My code for downloading is:

@GET(\"documents/checko         


        

Answer 1

For downloading, you can use ResponseBody as your return type --

@GET("documents/checkout")
@Streaming
public Call checkout(@Query("documentUrl") String documentUrl, @Query("accessToken") String accessToken, @Query("readOnly") boolean readOnly);

and you can get the ResponseBody input stream in your call back --

Call call = RetrofitSingleton.getInstance(serverAddress)
            .checkout(document.getContentUrl(), apiToken, readOnly[i]);

call.enqueue(new Callback() {
        @Override
        public void onResponse(Response response,
                Retrofit retrofit) {
            String fileName = document.getFileName();
            try {
                InputStream input = response.body().byteStream();
                //  rest of your code

Your upload looks okay at first glance if you server handles multipart messages correctly. Is it working? If not, can you explain the failure mode? You also might be able to simplify by not making it multipart. Remove the @Multipart annotation and convert @Path to @Body --

@POST("documents/checkin")
public Call checkin(@Query("documentId") String documentId, @Query("name") String fileName, @Query("accessToken") String accessToken, @Body RequestBody file);
