aquery 上传文件

gistfile1.txt

File dir = Environment.getExternalStorageDirectory();//获取SD卡目录
File file = new File(dir, "girl.jpg");//文件必须存在，自己放个同名的图片过去

AQuery aq = new AQuery(TestActivity.this);
String url = APIAgent.URL_SERVER_IMPRESSION_UPLOAD;
Map<String, Object> params = new HashMap<String, Object>();
params.put("message", "Message");
params.put("file", file);//可以传二进制数据也可以传文件
AjaxCallback<String> cb = new AjaxCallback<String>() {
            @Override
            public void callback(String url, String object, AjaxStatus status) {
                System.out.println(object);
                System.out.println(status.getCode());
                System.out.println(status.getMessage());
            }
        };
cb.cookie("Cookie", "PHPSESSID=ejfhv338ja3o20jt73rvjgslk2; path=/;REMEMBERME=b63a4e7c0e011a12a76624e7bf3d3a5cde8e5af9; expires=Sat, 07-Mar-2015 09:11:16 GMT; Max-Age=5184000; path=/; httponly");//有的时候需要带上Cookies
