当 JSON 语法错误时，如何将 JSONObject 转换为 JSONArray？

Question

我有目前的回应：

            "attackspeed":0.668
         }
      }
}
}

（最后两个大括号可能会关闭，因为我不得不缩短响应，因为它太大了）我正在尝试为每个冠军创建一个 JSONArray，所以首先是 Aatrox，其次是 Ahri，等等。）

由于此响应的语法，使用：

String returnString = (source);
JSONObject returnJSON = new JSONObject(returnString);
JSONArray arr= returnJSON.getJSONArray("data");

似乎不起作用，我认为这是因为 JSON 中缺少“[]”（方括号）。 有没有办法仍然可以使用当前的 state 创建 JSONArray？

提前致谢。

Answer 1

您需要了解 JSONObject 是键值对，而 JSONArray 是任何类型对象的列表。 您不能只将 jsonObject 转换为 JSONArray。 如果你想转换它你可以做这样的事情..

    JSONArray output = new JSONArray();
    JSONObject dataObj = returnJSON.getJSONObject("data");
    Set<String> keys = dataObj.keySet();
    for (String key : keys) {
        JSONObject obj = dataObj.getJSONObject(key);
        // your logic for populating output
    }

Answer 2

使用https://jsonformatter.curiousconcept.com/分析您的 JSON 文件，您似乎错过了第一个花括号。 添加它们会导致正确的结果。
