Moshi转换器阵列

Question

我有一个这样的JSON文档：

{ 
  cards: [{name: "Foo"}, {name: "Bar"}]
}

如何让moshi只解析属性卡下的数组？

Answer 1

首先，您在Jason中有一个错误。

card => "card“.

      String jsonResponseBody  = "{\n" +
            "    \"cards\": [\n" +
            "        {\n" +
            "            \"name\": \"Foo\"\n" +
            "        },\n" +
            "        {\n" +
            "            \"name1\": \"Bar\"\n" +
            "        }\n" +
            "    ]\n" +
            "}";

    Moshi moshi = new Moshi.Builder().build();
    JsonAdapter<BlackjackHand> jsonAdapter = moshi.adapter(BlackjackHand.class);

    try {
        BlackjackHand blackjackHand = jsonAdapter.fromJson(jsonResponseBody);
        System.out.println(blackjackHand);
        Log.e("TAG", "onCreate: "+blackjackHand.cards.get(0).name +"");
        Log.e("TAG", "onCreate: "+blackjackHand.cards.get(0).name1 +"");
    } catch (IOException e) {
        e.printStackTrace();
    }

BlackjackHand类：

    public class BlackjackHand {
    public final List<Card> cards;


    public BlackjackHand(List<Card> cards) {
        this.cards = cards;
    }
}

类卡：

public class Card {
    public final String name;
    public final String name1;

    public Card(String name, String name1) {
        this.name = name;
        this.name1 = name1;
    }
}

我们用json列表名称创建一个数据类，并用@Json指定它，它将是一个列表，我们已经以列表的形式接收到了数据。

data class Model(@Json(name = "name") val name: String)

data class ModelList(@Json(name = "cards") val cards: List<Model>)
