由于facebook现在停止了离线访问,我如何存储/获取新的访问令牌。我已经尝试了很多。代码如下。我必须在https://graph.facebook.com/me/friends?access_token=中提供访问令牌
String url = "https://graph.facebook.com/oauth/access_token?client_id=appid&client_secret=secretid&grant_type=fb_exchange_token&fb_exchange_token=access_token";
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
try{
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
is = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
result = result.split("=")[1];
AppLog.logger(result);
}
catch(Exception e)
{
AppLog.logger("Error in JSON");
}
如何兑换代币??请帮忙。
