带有Android Retrofit 2.X的Rails回形针宝石不起作用

Question

我正在创建 Rails 后端以使用回形针 gem 从浏览器和移动客户端 (Android) 上传图像。它适用于所有 Web 浏览器、移动浏览器以及 HTTP REST 客户端工具，但不适用于带有改造 http 库的 android 客户端。这是相互兼容的吗

Answer 1

答案是肯定的 让它工作并不容易，但是，

我是这样做的……它对我有用

接口声明

public interface MultimediaApi {

@Multipart
@POST("api/v1/multimedia")
Call<ResponseBody> uploadMultimedia(@Part("tipo]") String tipo,
                               @Part("archivo\"; filename=\"myimageName\" ") RequestBody archivo, // archivo is the how we named the field of the file in rails server
// see filename=\"myimageName\" does not have file extension to avoid problems with paperclip content types validations
                               @Part("texto") String texto,
                               @Part("acoplable_id") String acoplable_id,
                               @Part("acoplable_type") String acoplable_type
                              );
}

在执行线程上

Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(RestConnection.BASE_URL_MULTIMEDIA)
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build();

    MultimediaApi apiService =
            retrofit.create(MultimediaApi.class);

    Call<ResponseBody> call;
    MediaType MEDIA_TYPE = MediaType.parse("image/jpeg");
    File file = new File(filePath);
    RequestBody requestBody = RequestBody.create(MEDIA_TYPE, file);

    call = apiService.uploadMultimedia(
                        type.toString(),
                        requestBody,
                        text.toString(),
                        acopable_id.toString(),
                        acopable_type.toString()
                );

    Response<ResponseBody> response = call.execute();


        int statusCode = response.code();
        if (statusCode == 201) {
            // Server response OK            
        } else {
           //failed
                Throwable th = new Throwable("Status Code:" + statusCode + " Error uploading image... Response: " + response.body());
                return th;
            }

这个例子对我帮助很大，为了解决我的问题，我只是做了一些改变让它工作，所以要小心查看每个细节
