enhance volley with cookie & upload files
扩展Volley，实现请求携带Cookie，一次请求上传单个文件、多个文件同时上传等。

Jar

HttpClient 4.x
HttpCore 4.x

Add Gradle dependency:

dependencies {
   //wait.....

}

##1. JsonObjectRequestWithCookie can save or send cookie from http headers. code is just like volley :

  String urlStr = ".....";
        JsonObjectRequestWithCookie jsonObjectRequest = new JsonObjectRequestWithCookie(getApplicationContext(), Request.Method.GET, urlStr, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
            }
        }, null);
        //catch Cookie from http head
        // jsonObjectRequest.saveCookie(true);
        jsonObjectRequest.sendCookie();
        RequestQueue requestQueue = Volley.newRequestQueue(this);
        requestQueue.add(jsonObjectRequest);

the first param I use "getApplicationContext()" because of net request is out of UI thread. If you still use activity's context It may cause nullpointer ,when you are finish your activity request may still exist.

##2.upload files in same time you can also put string params when you are uploading files .

String urlStr = "......";
        MultiPartJSONRequest multiPartRequest = new MultiPartJSONRequest(getApplicationContext(), Request.Method.POST, urlStr, null,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
            }
        }) {
            //upload multi files
            public Map<String, File[]> getFilesUploads() {
                Map<String, File[]> params = new HashMap<>();
                params.put("images[]", new File[]{new File("absolute file path"), new File("absolute file path")});
                return params;
            }

            //string params
            public Map<String, String> getStringUploads() {
                Map<String, String> params = new HashMap<>();
                params.put("params", "....");
                return params;
            }
        };
        multiPartRequest.setCookie();
        RequestQueue requestQueue = Volley.newRequestQueue(this, new MultiPartStack());
        requestQueue.add(multiPartRequest);
