在android中解析twitter json響應時出錯

我嘗試使用Twitter獲取用戶/查找來查找用戶信息。但是在解析響應json文件時出現了一些錯誤。請求URI是：「https://api.twitter.com/1/users/lookup.json?screen_name=nba」。我的代碼是：在android中解析twitter json響應時出錯

public String getInternetData() throws Exception{ 
    String data = null; 
    try { 
     URI website = new URI("https://api.twitter.com/1/users/lookup.json?screen_name=nba"); 
     HttpClient client = new DefaultHttpClient(); 
     HttpGet request = new HttpGet(); 
     request.setURI(website); 
     HttpResponse response = client.execute(request); 
     HttpEntity entity = response.getEntity(); 
     String str = EntityUtils.toString(entity); 
     try { 
      JSONObject jouser = new JSONObject(str); 
      data = jouser.getString("followers_count"); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 

    }catch(Exception e){ 
     Log.e("log_tag", "Error in http connection: " +e.toString()); 
    } 
    return data; 
}

響應JSON內容

[ 
    { 
     "notifications":false, 
     "id":19923144, 
     "profile_link_color":"177BC7", 
     "profile_image_url_https":"https:\/\/si0.twimg.com\/profile_images\/1787324427\/National-Basketball-Association_normal.jpg",

     "id_str":"19923144", 
     "following":false, 
     "profile_use_background_image":true, 
     "profile_image_url":"http:\/\/a0.twimg.com\/profile_images\/1787324427\/National-Basketball-Association_normal.jpg", 
     "utc_offset":-18000, 
     "friends_count":988, 
     "profile_text_color":"333333", 
     "time_zone":"Eastern Time (US & Canada)", 
     "default_profile":false, 
     "followers_count":5095414, 
     "name":"NBA", 
     "profile_banner_url":"https:\/\/si0.twimg.com\/brand_banners\/NBA\/1335482314\/live", 
     "url":"http:\/\/www.nba.com", 
     "profile_sidebar_border_color":"eeeeee", 
     "created_at":"Mon Feb 02 19:04:42 +0000 2009", 
     "protected":false, 
     "listed_count":28499, 
     "profile_background_tile":false, 
     "contributors_enabled":true, 
     "profile_sidebar_fill_color":"ffffff", 
     "geo_enabled":false, 
     "description":"News and notes directly from the NBA.", 
     "location":"New York, NY", 
     "is_translator":false, 
     "show_all_inline_media":true, 
     "statuses_count":28818, 
     "follow_request_sent":false, 
     "lang":"en", 
     "profile_background_color":"000000", 
     "default_profile_image":false, 
     "verified":true, 
     "favourites_count":15, 
     "screen_name":"NBA", 
     "profile_background_image_url":"http:\/\/a0.twimg.com\/profile_background_images\/559347559\/12twitter_playoffs_0523.jpg" 
    } 
]

然後我得到了錯誤：*錯誤的數據進行解析：org.json.JSONException：值[{ 「位置」 ...... .. 有人有想法嗎？

如果響應以[開頭，則表示它實際上是JSON數組，而不是對象。然後，你將不得不這樣做：

JSONArray array = new JSONArray(str); 
JSONObject jsonObject = array.getJSONObject(0); 
String followersCount = jsonObject.getString("followers_count");

它確實以[開始。但我找不到這個數組的名字。就像在這個文件中，我應該在這個表達式中替換「pepe」的參數：JSONArray array = new JSONArray（pepe）？ –

pepe？什麼是佩佩？你在說什麼？ – Cristian

你說得對。這是一個JSONArray，而不是JSONObject。 JSONArray array = new JSONArray（str）;解決問題。謝謝身體！ –
