前一篇文章简单的介绍了okhttp的简单使用，okhttp的简单介绍（一）：http://blog.csdn.net/wuyinlei/article/details/50579564
相信使用还是很好使用的。
但是，怎么说呢，我们应该不想，每次使用的时候都去重新写一遍代码，或者是复制代码，这样不仅或降低效率，而且还会是代码冗余。
这个时候，采用封装就可以解决我们的问题了，把相同的代码，封装到一起，对外提供一个调用的接口，每次调用的时候，我们只需要调用接口，传入数据，就可以了，我们完全不用去理会他内部逻辑是怎么处理的
那好的，既然已经知道了怎么去做，那么我们就开始吧。
我们想要实现的结果：
对外提供GET同步请求和内部逻辑处理
3、对外提供的同步获取数据的方法和内部处理
4、异步请求做的处理
在这里我们对回调Callback进行了处理，改成我们自定义的接口
然后自定义了两个方法
一个是请求失败：
一个是请求成功：
5、异步请求逻辑处理
6、表单提交逻辑处理
7、文件下载逻辑处理
实现效果是一样的，但是代码结构清晰许多哈：
这样，就完成了简单的一个请求工具类的封装。这里的异步请求处理，我只是返回了字符串，如果想返回的直接是个对象，这个还得需要处理。在这由于知识尚浅，尚不能完成对象的返回。我们看到上面的，其实也就是遵循了okhttp的GET，POST请求的逻辑，在次基础上，我们增加了一些方法，来完成我们想要的功能。下面上传代码，有点多，大家担待点哈：

/请求成功</span>
<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">void</span> requestSuccess(String result) <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">throws</span> Exception;

这样，就完成了简单的一个请求工具类的封装。这里的异步请求处理，我只是返回了字符串，如果想返回的直接是个对象，这个还得需要处理。在这由于知识尚浅，尚不能完成对象的返回。我们看到上面的，其实也就是遵循了okhttp的GET，POST请求的逻辑，在次基础上，我们增加了一些方法，来完成我们想要的功能。下面上传代码，有点多，大家担待点哈：
