七牛上传文件
现在越来越多的项目会使用云存储，一些图片视频资源不会再放到自己的服务器中。目前市场上用的最多的应该是阿里云、腾讯云 、七牛云吧。今天我们主要讲的是七牛云。七牛官方文档
看了官方文档后，我们首先要知道为了安全，我们上传东西所需要的秘钥肯定是通过服务端获取，不可能是放在自己本地的。为了使用方便，我把七牛上传封装成一个简单的单例工具类。
七牛的上传是自己生成上传的key ，上传成功后，会返回你上传的key 以及一个hash值。你只需要将key 与 在七牛后台设置的资源server 拼接起来，就可以拿到资源了。 建议拼接这个事，最好让后台进行,说不定server会改变

上传这些东西都很简单。封装成工具类，方便调用，统一处理，非常方便。视频音频上传路径，图片可以直接上传。
