如何从 json 中获取 int 的实际价值

Question

In my project I have an int jsonobject by 20 value. To get the int value I used this:

model.setInt(jsonObject.getInt("price"));

Now it returns 0 value for price. How can I get real value?

Here is My out put Json:

      "data": [
    {
      "id": "571dd7817f8b9a1c190bbdb5",
      "goods": 0,
      "rate": {
        "r1": 0
      },
      "price": 20
     }

Answer 1

Please look at the example:

String jsonData = "{\"count\": 20}";
JSONObject obj = new JSONObject(jsonData);
System.out.println("Count: " + obj.getInt("count"));

Answer 2

Your JSON is invalid. you can use online tools like the jsonformatter to test the validity of your JSON .

Maybe try something like:

{
    "data": [
      {
        "id": "571dd7817f8b9a1c190bbdb5",
        "goods": 0,
        "rate": {"r1": 0},
        "price": 20
      }
    ]
}

Looking at your code, you may have better luck with this structure:

{
    "id": "571dd7817f8b9a1c190bbdb5",
    "goods": 0,
    "rate": {"r1": 0},
    "price": 20
}
