okhttp的簡單介紹（二）之簡單封裝

• 前一篇文章簡單的介紹了okhttp的簡單使用，okhttp的簡單介紹（一）：http://blog.csdn.net/wuyinlei/article/details/50579564 
  相信使用還是很好使用的。

• 但是，怎麼說呢，我們應該不想，每次使用的時候都去重新寫一遍代碼，或者是複製代碼，這樣不僅或降低效率，而且還會是代碼冗餘。

• 這個時候，採用封裝就可以解決我們的問題了，把相同的代碼，封裝到一起，對外提供一個調用的接口，每次調用的時候，我們只需要調用接口，傳入數據，就可以了，我們完全不用去理會他內部邏輯是怎麼處理的
• 那好的，既然已經知道了怎麼去做，那麼我們就開始吧。

我們想要實現的結果：

實現效果是一樣的，但是代碼結構清晰許多哈： 
 

這樣，就完成了簡單的一個請求工具類的封裝。這裏的異步請求處理，我只是返回了字符串，如果想返回的直接是個對象，這個還得需要處理。在這由於知識尚淺，尚不能完成對象的返回。我們看到上面的，其實也就是遵循了okhttp的GET，POST請求的邏輯，在次基礎上，我們增加了一些方法，來完成我們想要的功能。下面上傳代碼，有點多，大家擔待點哈：
