在android中使用截击从标头获取令牌

我正在开发android应用程序，我想使用服务器json响应中的截图从标题中获取令牌，并将其存储在sq lite中以维护用户会话，我在任何地方搜索bt，但我不知道如何从json中检索令牌，请帮助我解决此问题

这是我的json响应

{ "token": "eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiI5ODkzMjY3OTQ0IiwiYXVkIjoid2‌​ViIiwiZXhwIjoxNTA1OD‌​EwNTQ5LCJpYXQiOjE1MD‌​UyMDU3NDl9.cf9QGwp7z‌​LVSTuiunClkauTFEXe6j‌​tcNCxzqIntEtmWTDfLqA‌​D3nKiXIf-fg0vEV_74SO‌​cPVYxDcTUwCZqntVA" } 

试试这个

JSONObject jsonObject = new JSONObject("your json string");
 String token= jsonObject.optString("token");

  JSONObject jsonObject = null;
            try {
                jsonObject = new JSONObject(response);
                String access_token= jsonObject.optString("access_token");
                 Log.v("####","hellow token  " + access_token);
            } catch (JSONException e) {
                e.printStackTrace();
