改型-使用Gson解析json的问题

闻人德庸
2023-03-14

我是新来改装的。我已经在大多数Web服务中使用了volley，决定继续改进。但是我被Json解析所困，我在POJO类中得到了空数据。我尝试通过调用 检查响应，我的响应是正确的，当我在模型类中解析时，我得到的是空白数据。请指导我，任何帮助都将不胜感激。

注意：POJO类是可parcelable，还包含cunstructor和gette/setter。我从这里删除了它，因为文本限制。

Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(PRODUCT_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();
    ApiInterface apiService = retrofit.create(ApiInterface.class);
    JsonObject ob = new JsonObject();
    ob.addProperty("pro_id", model.getId());
    Call<Product> call = apiService.getProducts(ob);
    call.enqueue(new Callback<Product>() {
        @Override
        public void onResponse(Call<Product> call, Response<Product> response) {
            Product p = response.body();
            Toast.makeText(getActivity(), response.body().getTitle(), Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFailure(Call<Product> call, Throwable t) {
            Log.e("ERROR",call.toString());
        }
    });

public interface ApiInterface {
     @POST("app/product.php")
     Call<Product> getProducts(@Body JsonObject jsonObject);
}

虽然使用json对象将json数据发送到URL，但主要目的是获取数据，因此注释应该是get而不是post

public interface ApiInterface {
     @GET("app/product.php")
     Call<Product> getProducts(@Body JsonObject jsonObject);
}
