JSONの結果に「有効な応答」と表示されるJSONの結果があります。動的なキー名でネストされたjsonを解析する方法
私の質問は、「集約」のコンテンツにアクセスし、キーが動的な入れ子の子オブジェクトから値を抽出する方法です。私は再帰的にどのように動的なキーを取得する考えを取得し、キー/値ペアの地図を形成ジャクソンを使用してではなく、JSONを解析するために、いくつかの組み合わせを試してみました
[
{
"metric_date":"2017-06-01 12:06:00",

"avg_avail_secs":1036800

：以下のように私の応答オブジェクトは、期待しました。
private Object parseValue(Object inputObject, List<String> keys) throws JSONException {
Object outputObject = null;
if (null != inputObject) {
if (inputObject instanceof JSONArray) {
outputObject = parseJSONArray((JSONArray) inputObject, keys);
} else if (inputObject instanceof JSONObject) {
outputObject = parseJSONObject((JSONObject) inputObject, keys);
} else if (inputObject instanceof String || inputObject instanceof Boolean || inputObject instanceof Integer) {
outputObject = inputObject;
}
}
return outputObject;
}

使用しているJSONライブラリを教えてください。これまでJavaコードはどこにありますか？ –
@ cricket_007、私はjacksonを使用しており、問題のJavaコードを追加しました。 – SSD
