android - 通过 JsonObjectRequest 将 session cookie 与 android volley 库一起使用

Question

如何通过 volley 库使用 session cookie 处理这样的请求？

JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

     @Override
     public void onResponse(JSONObject response) {
        //Response
     }
    }, new Response.ErrorListener() {

     @Override
     public void onErrorResponse(VolleyError error) {
        //Error
     }
});
queue.add(jsObjRequest);

谢谢

这是我使用 Volley 和 JsonObjectRequest 保存 cookie 的方式

我的想法是捕获随我的 Json 请求返回的 Set-Cookie header ，然后将其保存在首选项中

请求

            JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST,
                url,
                (String)param,
                requestFuture, requestFuture){

            @Override
            public String getBodyContentType() {
                return "application/x-www-form-urlencoded";
            }


            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                Show.m("getHeaders");

                Map<String,String> headers = new HashMap<String, String>();
                headers.put("Accept","application/json");


                if(!MyApplication.getCookie(context).equals("")){
                    String cookie = MyApplication.getCookie(context);
                    Show.m("Cookie to load from preferences: " + cookie);
                    headers.put("Cookie", cookie);
                }

                return headers;
            }

            @Override
            protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
                Map headers = response.headers;
                String cookie = (String)headers.get("Set-Cookie");
                MyApplication.saveCookie(context, cookie);

                Show.m("Cookie to save to preferences: " + cookie);

                return super.parseNetworkResponse(response);
            }
        };

偏好设置

    public static void saveCookie(Context context, String cookie) {
        if (cookie == null) {
            return;
        }

        // Save in the preferences
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
        if (null == sharedPreferences) {
            return;
        }
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString("cookie", cookie);
        editor.commit();
    }

    public static String getCookie(Context context)
    {
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
        String cookie = sharedPreferences.getString("cookie", "");
        if (cookie.contains("expires")) {
            removeCookie(context);
            return "";
        }
        return cookie;
    }
