android - 如何在android改造中发送json数组？

Question

我无法将 json 数组发送到服务器。当我在 postman raw 中测试时，没关系，成功返回。

postman 生；

[
    {
        "product_id": 2,
        "name": "Umbrella",
        "price": 200,
        "quantity": 1,
        "totalprice": 200,
        "user_id": 1
    },
    {
        "product_id": 1,
        "name": "Apple",
        "price": 200,
        "quantity": 1,
        "totalprice": 200,
        "user_id": 1
    }
]

API接口(interface)；

@POST("example/api/order")
Call<JSONArray> postOrder(@Body JSONArray jsonArray);

购物车 Activity ；

try {
    JSONArray jsonArray = new JSONArray();
    for (Cart cart : cartList) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("product_id", cart.getProduct_id());
        jsonObject.put("name", cart.getName());
        jsonObject.put("price", cart.getPrice());
        jsonObject.put("quantity", cart.getQuantity());
        jsonObject.put("totalprice", cart.getTotalprice());
        jsonObject.put("user_id", cart.getUser_id());
        jsonArray.put(jsonObject);
    }
    Log.e("JSONArray", String.valueOf(jsonArray));
} catch (JSONException jse) {
    jse.printStackTrace();
}

日志;

E/JSONArray: [{"product_id":1,"name":"Umbrella","price":200,"quantity":1,"totalprice":200,"user_id":1},{"product_id":2,"name":"Apple","price":89,"quantity":1,"totalprice":89,"user_id":1}]

来自服务器的错误消息；

{"values":[{"nameValuePairs":{"product_id":1,"name":"Umbrella","price":200,"quantity":1,"totalprice":200,"user_id":1}},{"nameValuePairs":{"product_id":2,"name":"Apple","price":89,"quantity":1,"totalprice":89,"user_id":1}}]}

您可以直接将对象数组作为参数发送。改造将处理转换。像这样更改您的接口(interface)方法:

@POST("example/api/order")
Call<JSONArray> postOrder(@Body List<Cart> cartList);
