Android使用OKHttp访问网络获取Cookie和带Cookie的请求

登录，取得Cookie

public void login(String username, String userpwd) {
    FormBody body = new FormBody.Builder().add("email", username).add("passwd", userpwd).build();
    Request request = new Request.Builder().url(application.getURL() + "/auth/login").post(body).build();
    Call call = new OkHttpClient().newCall(request);
    call.enqueue(new Callback() {
        @Override
        public void onFailure(Call call, IOException e) {

        }

        @Override
        public void onResponse(Call call, Response response) throws IOException {
            Headers headers = response.headers();
            HttpUrl loginUrl = request.url();
            List<Cookie> cookies = Cookie.parseAll(loginUrl, headers);
            cookieStr = new StringBuilder();
            for (Cookie cookie : cookies) {
                cookieStr.append(cookie.name()).append("="
