Question

这是我的课程，我正在使用api来打电话。产品，产品，终点ZappoAPI。从控制器调用方法callRestAPI，其中异步调用rest api。我得到了空列表作为回应。

public class Product {
    private String productId;

    public Product(String productId) {
        this.productId = productId;
    }


    public String getBrandName() {
        return productId;
    }

    public void setBrandName(String productId) {
        this.productId = productId;
    }

    @Override
    public String toString() {
        return(productId);
    }
}



public class Products {
    List<Product> products  = new ArrayList<>();
    public List<Product> getProducts() {
        return products;
    }
}



public interface ZappoAPI {
    @GET("/Search")
    Call<ZappoProducts> searchProducts(@Query("term") String tags, @Query("key") String key);

}

public void callRestAPI（）{

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.zappos.com")
        .addConverterFactory(GsonConverterFactory.create())
        .build();




// prepare call in Retrofit 2.0
ZappoAPI zappoAPI = retrofit.create(ZappoAPI.class);

Call<ZappoProducts> call = zappoAPI.searchProducts(this.prodName, IConstant.API_KEY);
//asynchronous call
call.enqueue(this);

String url = call.request().url().toString();

Log.d("url is",url);
Log.d("url is",url);

}

on callback method -

public void onResponse(Call<ZappoProducts> call, Response<ZappoProducts> response) {

        boolean isSuccess = response.raw().isSuccessful();
        List<Product> products = new ArrayList<>();

        if(isSuccess){
            products = response.body().getProducts();
        }


        String[] values = new String[products.size()];


        for (int i=0;i<products.size();i++){
            values[i] = products.get(i).toString();
        }

        ArrayAdapter<String> adapter = (ArrayAdapter<String>) this.adapter;
        adapter.clear();
        adapter.addAll(values);



    }

现在，响应，我正在获得空产品清单。知道怎么解决吗？

Retrofit API调用返回空对象
