推荐答案

使用这个

Retrofit retrofit = new Retrofit.Builder().client(okHttpClient).baseUrl(domain)
            .addConverterFactory(GsonConverterFactory.create()).build();
   Service service = retrofit.create(Service.class);

   RequestBody requestBody = RequestBody.create(MediaType.parse("*/*"), file);

   final MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("file", file.getName(), requestBody);
   final RequestBody filename = RequestBody.create(MediaType.parse("text/plain"), file.getName());

   Call<ServerResponse> upload = service.uploadFile(fileToUpload, filename);

   upload.enqueue(new Callback<ServerResponse>() {
        @Override
        public void onResponse(Call<ServerResponse> call, final Response<ServerResponse> response) {
            final ServerResponse serverResponse = response.body();
            if (serverResponse.getSuccess()) {
                //Handle Response
            }
        }

        @Override
        public void onFailure(Call<ServerResponse> call, Throwable t) {
            if(t instanceof SocketTimeoutException){
                Toast.makeText(getApplicationContext(), "Unable To Upload\nError: Socket Time out. Please try again", Toast.LENGTH_LONG).show();
            }
            t.printStackTrace();
        }
    });

服务接口

public interface Service {
@Multipart
@POST("path/upload.php")
Call<ServerResponse> uploadFile(@Part MultipartBody.Part file, @Part("file") RequestBody name);

}
