okhttp框架获取sessionid操作

OkHttpUtils
.get()
.url(Constant.HTTP_URL + "login")
.addParams("username", mLoginAccount)
.addParams("password", mLoginPassword)
.build()
.execute(new StringCallback() {
@Override
public void onError(Call call, Exception e, int id) {
}

                @Override
                public void onResponse(String response, int id) {
                    handleData(response);
                }

                @Override
                public String parseNetworkResponse(Response response, int id) throws IOException {
                    //获取session的操作，session放在cookie头，且取出后含有“；”，取出后为下面的 s （也就是jsesseionid）
                    Headers headers = response.headers();
                    Log.e(TAG, "header " + headers);
                    List<String> cookies = headers.values("Set-Cookie");
                    String session = cookies.get(0);
                    Log.e(TAG, "onResponse-size: " + cookies);
                    String s = session.substring(0, session.indexOf(";"));
                    Log.e(TAG, "session is :" + s);
                    return super.parseNetworkResponse(response, id);
                }
            });

使用时：
OkHttpUtils
.post()
.url(Constant.HTTP_URL + "query")
.addHeader("cookie", s))
.build()
.execute(new StringCallback() {
