asynchttpclient android studio,網絡請求架構----AsyncHttpClient的get,post和圖檔上傳伺服器...

async-http-client庫是一個基于回調函數的Http異步通信用戶端Android元件，是在Apache的HttpClient庫的基礎上開發建構而成的。

Eclipse使用：導入android-async-http-1.4.4.jar包 http://download.csdn.net/detail/dickyqie/9662215

AndroidStudio: gradle中引入 compile 'com.loopj.android:android-async-http:1.4.8'

功能特色

· 利用版4.3.6上遊HttpClient代替Android提供defaulthttpclient

· 相容AndroidAPI 23高

· 做異步HTTP請求處理的響應匿名回調

· HTTP請求發生UI線程之外

· 請求使用線程池限制并發資源使用情況

· get /後參數生成器( RequestParams )

· 多檔案上傳沒有額外的第三方庫

· JSON上傳流沒有額外的圖書館

· 處理循環和相對重定向

· 小的開銷給你的應用程式隻90kb一切

· 自動智能請求重試次數品質不一的移動連接配接優化

· 自動gzip響應解碼速度超快的請求支援

· 二進制協定通信binaryhttpresponsehandler

· 内置的響應分析JSON與jsonhttpresponsehandler

· 節能反應直接進入檔案fileasynchttpresponsehandler

· 大的持久性Cookie，儲存cookie到你的應用程式的SharedPreferences

· 傑克遜JSON內建，gson或其他JSON序列化庫(德)basejsonhttpresponsehandler

· 與SAX解析器支援saxasynchttpresponsehandler

· 語言和内容編碼的支援，不僅僅是UTF-8
