架构图

方案架构

架构描述

该解决方案会部署如下资源:

1.创建用于上传图片的对象存储服务(OBS)桶,企业业务系统将需要生成缩略图的图片上传至此桶;

2.创建用于存储缩略图结果的对象存储服务(OBS)桶,企业业务系统从该桶中获取缩略图结果;

3.函数工作流:用于实现调用对象存储服务及缩略图生成,当OBS桶收到上传的图片文件后,会自动通知函数服务生成缩略图,并将结果存放到指定的OBS桶;

4.通过统一身份认证服务的委托功能,将帐号Region内OBS的操作权限委托给函数工作流服务。

开始使用

1、登录华为云对象存储服务控制台,查看自动创建的OBS桶列表:

图1 对象存储服务控制台 对象存储服务控制台

2、选择用于上传和存储图片的桶“image_bucket_demo”,上传图片:

图2 上传图片 上传图片

3、选择用于存放结果的“result-bucket-demo”桶,即可获取以上传图片名称为前缀命名的缩略图:

图3 获取缩略图文件 获取缩略图文件

4、另外,您也可以通过华为云SDK使用,企业业务系统可通过华为云提供的SDK服务与OBS桶进行对接,当上传图片到华为云OBS桶后,即可自动生成图片缩略图,企业业务系统只需从存储结果的OBS桶中获取结果,即可实现生成图片缩略图的自动化处理流程。SDK详细使用流程可参考华为云官网SDK用户指南
