如何解析嵌套JSON结果的动态JSON关键 [英] How to parse a dynamic JSON key in a Nested JSON result

问题描述

我有一个JSON结果在下面的格式， JSON林特显示这是一个有效响应。

I have a JSON result in the following format which JSON Lint shows this as a "Valid Response".

我的问题是：我怎么访问question_mark，因为141的内容，8911等都是动态值？

My question is: how do I access the content of "question_mark" since "141", "8911", etc are all dynamic values?

我的样品code来访问产品的价值。

My sample code for accessing value of "product".

//Consider I have the first <code>JSONObject</code> of the "search_result" array and 
//I access it's "product" value as below.
String product = jsonObject.optString("product"); //where jsonObject is of type JSONObject.
//<code>product<code> now contains "abc".

JSON：

{
 "status": "OK",
 "search_result": [

            {
                "product": "abc",
                "id": "1132",
                "question_mark": {
                    "141": {
                        "count": "141",
                        "more_description": "this is abc",
                        "seq": "2"
                    },
                    "8911": {
                        "count": "8911",
                        "more_desc": "this is cup",
                        "seq": "1"
                    }
                },
                "name": "some name",
                "description": "This is some product"
            },
            {
                "product": "XYZ",
                "id": "1129",
                "question_mark": {
                    "379": {
                        "count": "379",
                        "more_desc": "this is xyz",
                        "seq": "5"
                    },
                    "845": {
                        "count": "845",
                        "more_desc": "this is table",
                        "seq": "6"
                    },
                    "12383": {
                        "count": "12383",
                        "more_desc": "Jumbo",
                        "seq": "4"
                    },
                    "257258": {
                        "count": "257258",
                        "more_desc": "large",
                        "seq": "1"
                    }
                },
                "name": "some other name",
                "description": "this is some other product"
            }
       ]
}

我的提问标题为动态密钥可能是错误的，但我不知道在这一点上有什么针对此问题的更好的名字做。

My question title "dynamic key" could be wrong but I don't know at this point what's a better name for this issue.

任何帮助将是很大的AP preciated！

Any help would be greatly appreciated!

推荐答案

使用 JSONObject的键（）拿到钥匙，然后遍历每个键进入动态值。

Use JSONObject keys() to get the key and then iterate each key to get to the dynamic value.

大约在code将是这样的：

Roughly the code will look like:

    // searchResult refers to the current element in the array "search_result"
    JSONObject questionMark = searchResult.getJSONObject("question_mark");
    Iterator keys = questionMark.keys();

    while(keys.hasNext()) {
        // loop to get the dynamic key
        String currentDynamicKey = (String)keys.next();

        // get the value of the dynamic key
        JSONObject currentDynamicValue = questionMark.getJSONObject(currentDynamicKey);

        // do something here with the value...
    }
