Answer 1

试试这个..

try 
{ 
    JSONObject object = new JSONObject(response); 
    String refresh_token = object.getString("refresh_token"); 

}catch (JSONException e) { 
    e.printStackTrace(); 
} 

Answer 2

这是可以做到这样的：

public String getToken(String url) throws JSONException { 
    DefaultHttpClient httpclient = new DefaultHttpClient(); 
    HttpGet httpGet = new HttpGet(url); 
    try { 
     HttpResponse response = httpclient.execute(httpGet); 
     JSONObject data = new JSONObject(EntityUtils.toString(response.getEntity())); 
     return data.getString("refresh_token"); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    return null; 
}
