• android 向serverGet和Post请求的两种方式,android向server发送文件,自己组装协议和借助第三方开源


    一个适用于Android平台的第三方和apache的非常多东西类似,仅仅是用于Android上

    我在项目里用的是这个

    https://github.com/loopj/android-async-http

     AsyncHttpClient  client = new AsyncHttpClient();


    RequestParams params = new RequestParams();
    params.put(JsonKey.JSON_K_MOBILE, "1526808");
    params.put(JsonKey.JSON_K_COUPON, coupon);

    put(File,...);
