I tried the following but on response i am getting 500 error (Internal Server Error) -- help me design the interface for the request in the above screenshot...thanks

@Multipart
@POST("myrecord")
Call<ResponseBody> addRecord(@Query("token") String token,@Query("userid") int userId,
                             @Query("name") String name, @Part("file") RequestBody file);


File file = new File(getRealPathFromURI(data.getData()));
RequestBody requestFile = RequestBody.create(MediaType.parse("image/*"), getRealPathFromURI(data.getData()));` 
Call<ResponseBody> responseBodyCall = service.addRecord(token, userId,
                "newFileName", requestFile);
        responseBodyCall.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                Log.d("Response", "="+response.code());
                Log.d("Response", "= "+response.message());

            }

            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {
                Log.d("failure", "message = " + t.getMessage());
                Log.d("failure", "cause = " + t.getCause());
            }
        });`

推荐答案

以下代码有效 :)

 @Multipart
@POST("myrecord")
Call<ResponseBody> addRecord(@Query("token") String token, @Query("userid") int userId,
                             @Query("name") String name, @Part MultipartBody.Part file);



 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if ((requestCode == FILE_SELECT_CODE) && (resultCode == -1)) {

        File file = new File(getRealPathFromURI(data.getData()));

        RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), getRealPathFromURI(data.getData()));

        MultipartBody.Part multipartBody =MultipartBody.Part.createFormData("file",file.getName(),requestFile);

        Call<ResponseBody> responseBodyCall = service.addRecord(token, userId, "fileName", multipartBody);
        responseBodyCall.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                Log.d("Success", "success "+response.code());
                Log.d("Success", "success "+response.message());

            }

            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {
                Log.d("failure", "message = " + t.getMessage());
                Log.d("failure", "cause = " + t.getCause());
            }
        });

    }
}
