Java JSON對象-如何在響應中從Facebook獲得給定權限的結果，或者值是1還是0

Question

下面是對權限的查詢-我正在嘗試查看是否授予了特定的燙發。任何幫助將不勝感激...

 JSONObject permissions = new JSONObject(
                         IOUtil.urlToString(new URL("https://graph.facebook.com/me/permissions?access_token=AAACEdEose0cBALhOmvDd14yIJQUTZAJ4GxFmkaHQmGKfwBwS1I32GAIsJolPZAgqB3prnVXqrvwlInYxcutnOOVFdRY6RBcgWfGT46KrSgMzdjnG6U")));



Here is the sample responce {"data": [
{
  "installed": 1,
  "user_likes": 1,
  "publish_stream": 1,
  "user_interests": 1,
  "user_hometown": 1,
  "user_groups": 1,
  "type": "permissions"
}]}

Answer 1

要獲取“已安裝”值：

permissions.getJSONObject("data").getInt("installed");

然后根據需要進行比較。
