Question

请问我如何post这个JSON

 {

  "type": "simple",
  "regular_price": "21.99",
  "description": "Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.",
  "short_description": "Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.",
  "categories": [
    {
      "id": 9
    },
    {
      "id": 14
    }
  ],
  "images": [
    {
      "src": "http://demo.woothemes.com/woocommerce/wp-content/uploads/sites/56/2013/06/T_2_front.jpg"
    },
    {
      "src": "http://demo.woothemes.com/woocommerce/wp-content/uploads/sites/56/2013/06/T_2_back.jpg"
    }
  ]
}

到 android 改造

我已经成功发送了一个字符串，但是这个数组我不能喜欢发送图片

我的代码

API

    {
public interface interfaceAPI

    @POST("wp-json/wc/v3/products?consumer_key=ck_006dd346d4c87128f924a93983e7d51be528d1&consumer_secret=cs_d4b421317da42bd58a3f3db6a4cc4644d20a78e3")
    Call<Product> PRODUCT_CALL_POST(@Body HashMap<Object, Object> map);



}

我试过使用 JSONObject，但它不起作用

HashMap 部分解决了问题。

希望得到您的帮助

任何帮助将不胜感激:) 祝你好运

Answer 1

辛苦了几天，我的问题终于解决了:)

    HashMap<Object,Object> map = new HashMap<>();
    map.put( name ,"Premium Quality222" );
    map.put( regular_price ,"21.99" );
      images = new images("http://demo.woothemes.com/woocommerce/wp-content/uploads/sites/56/2013/06/T_2_front.jpg");
      ArrayList<images> imagesArrayList = new ArrayList<com.example.myapplication.Model.images>();
      imagesArrayList.add(images);
    map.put(imagesString , imagesArrayList);
      ArrayList<categories> categoriesArrayList = new ArrayList<>();
      categories = new categories(111);
      categoriesArrayList.add(categories);
    map.put(categoriesString, categoriesArrayList);


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

    interfaceAPI = retrofit.create(com.example.myapplication.callAPI.interfaceAPI.class);

    Call<Product2> productCall= interfaceAPI.PRODUCT_CALL_POST(map);
