        阿里云账号AccessKey拥有所有API的访问权限，建议您使用RAM用户进行API访问或日常运维。
        建议不要把AccessKey ID和AccessKey Secret保存到工程代码里，否则可能导致AccessKey泄露，威胁您账号下所有资源的安全。
        本示例以将AccessKey和AccessSecretKey保存在环境变量中实现身份验证为例。
        运行本示例前请先在本地环境中设置环境变量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET。
        在FC Runtime运行环境下，配置执行权限后，ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET环境变量会自动被设置。
