Question

我使用以下方法编码图像

 Bitmap bm = BitmapFactory.decodeFile(mCurrentPhotoPath);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
    byte[] byteArrayImage = baos.toByteArray();
    encodedImage = Base64.encodeToString(byteArrayImage, Base64.DEFAULT);`

我发送的数据来自改造，如下所示：

newFoodModel = new NewFoodModel(food_name,food_unit,food_price,encodedImage,providerId,foodCategoryId);

        Call<ServiceResponse>serviceResponseCall = uploadFoodApi.getResponseResult(newFoodModel);
        serviceResponseCall.enqueue(new Callback<ServiceResponse>() {
            @Override
            public void onResponse(Call<ServiceResponse> call, Response<ServiceResponse> response) {
                if(response.code() == 200){
                    ServiceResponse serviceResponse = response.body();
                    Toast.makeText(AddFoodActivity.this, serviceResponse.getMessage(), Toast.LENGTH_SHORT).show();
                }else{
                    Toast.makeText(AddFoodActivity.this, response.code()+","+response.message(), Toast.LENGTH_SHORT).show();
                }
            }

            @Override
            public void onFailure(Call<ServiceResponse> call, Throwable t) {
                Toast.makeText(AddFoodActivity.this, "Check connection", Toast.LENGTH_SHORT).show();
            }
        });

我不知道我在哪里做错了，来自服务器的响应是错误代码：500，内部服务器错误。

我的回复模型类：

public class ServiceResponse {
    @SerializedName("ResultState")
    @Expose
    private Boolean resultState;
    @SerializedName("Message")
    @Expose
    private String message;

    public Boolean getResultState() {
        return resultState;
    }

    public void setResultState(Boolean resultState) {
        this.resultState = resultState;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
}

处理请求的接口：

public interface UploadFoodApi {
    @POST("after_part_of_base_url")
    Response<ServiceResponse> getResponseResult(@Body NewFoodModel newFoodModel);
}

由于图片尺寸，图片未上传：

bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream );// image quality was kept 100%

我通过降低质量来解决问题，

bitmap.compress(Bitmap.CompressFormat.JPEG, 80, byteArrayOutputStream ); //it is now scaled down to 80% of original image.

无法使用Retrofit将Base64 String传递给对象
