编程使用:
# 选项传递的 Hash 值可以是任意形态的，实现中利用 hashie 抹平了差异
BbsUploader.qiniu = {
access_key: 'your access key',
secret_key: 'your secret key',
bucket: "your bucket",
bucket_domain: "your application domain"
}
# 超集方法：可以上传任意的文件
BbsUploader.upload '~/Downloads/test.jpg'
BbsUploader.upload 'http://xiajian.github.io/assets/images/dongxiang.png'
BbsUploader.upload_image '~/Downloads/test.jpg'
BbsUploader.upload_file '~/Downloads/install.php'
# 添加将整个目录按照自然的顺序上传上去
BbsUploader.upload_with_directory '~/Downloads/pi'
然后，就祝君安好！！！
PS: 思考 网盘以及 CDN 在部署的上区别。 CDN 内容分发，网盘就是云存储。 这就不明白，SB！！ 上传的 js 以及 css 文件，直接下载获取，不如 专业的 cdn 资源的获取的速度快，所以，专业的 CDN 系统还是有特殊的优化处理的。
后续开发
- 可以添加一个全局配置七牛的 key 以及相关的功能， 配置文件，可以放在
~/.bbs_uploader中，文件的解析，可以参考 dotenv 中关于文件的解析方法(Parser)。 - 可能需要添加新的 qiniu sdk 的接口的调用。
- 控制日志输出的等级
Development
After checking out the repo, run bin/setup to install dependencies. Then, run rake false to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
