java - 解析 JSON 失败，因为不是 JSONArray

Question

我正在尝试在 Java 程序中解析以下 JSON。

JSON

{
    "data": {
        "pageIDentifier":" nametitle",
        "page": {
            "pageID”:” sports_league_member",
            "platform":" www",
            "activityType":" ent",
            "businessUnit":" ent",
            "productLOB":" ent",
            "productOffered":" abc",
            "productQualifier”:” abc:a bc”,
            "flowType”:” sports_com”,
            "pageDesc”:” desc”,
            "attributes": {
                "pageType":" www",
                "host”:” finaluser”,
                "appId”:” SportsAppID_user”,
                "daEnvironment”:” releaser”,
                "jvm":" ent_logon_01",
                "xCKey":" SportsAppID_user",
                "daUID":" jddc9yu5pi1yy6",
                "sysEnv”:” user”,
                "uri”:” /www/sportscenter”,
                "daPageName":" "
            }
        }
    }
}

JAVA程序

URL url = getClass().getResource("test.json");
File file = new File(url.getPath());
String jsonData = readFile(file.getAbsolutePath());
JSONObject jobj = new JSONObject(jsonData);
JSONArray jarr = new JSONArray(jobj.getJSONArray("data").toString());
System.out.println("jarr: " + jarr);

执行此代码时出现以下错误。请注意，jsonData 给出了整个 json 字符串，没有任何问题。

org.json.JSONException: JSONObject["data"] is not a JSONArray.

如何从上面的 json 值中解析“data”值？请指教。

Answer 1

数据不是数组

试试这个:

System.out.println("jarr: " + jobj.getJSONObject("data").toString());
