*@ClassName: TestOSS
*
*@Description: 该示例代码展示了如果在OSS中创建和删除一个Bucket，以及如何上传和下载一个文件。
*
* 该示例代码的执行过程是：
* 1. 创建一个Bucket（如果已经存在，则忽略错误码）；
* 2. 上传一个文件到OSS；
* 3. 下载这个文件到本地；
* 4. 清理测试资源：删除Bucket及其中的所有Objects。
*
* 尝试运行这段示例代码时需要注意：
* 1. 为了展示在删除Bucket时除了需要删除其中的Objects,
* 示例代码最后为删除掉指定的Bucket，因为不要使用您的已经有资源的Bucket进行测试！
* 2. 请使用您的API授权密钥填充ACCESS_ID和ACCESS_KEY常量；
* 3. 需要准确上传用的测试文件，并修改常量uploadFilePath为测试文件的路径；
* 修改常量downloadFilePath为下载文件的路径。
* 4. 该程序仅为示例代码，仅供参考，并不能保证足够健壮。
