go调用阿里云接口查询ECS信息

1、RAM访问控制

1.1 创建用户：访问方式：Open API 调用访问
1.2 记得保存AK，一定要复制保存
1.3 权限管理—>新增授权---->只读访问所有阿里云资源的权限
注意：此处因为我初次练习使用，用了只读权限，初学者建议使用只读权限，如果有写权限，OpenAPI可直接调用操作资源

2、阿里云官方ECS API接口地址

文档中示例代码仅供参考，真正的该产品 SDK 的使用步骤请参见：https://next.api.aliyun.com/api/Ecs/2014-05-26

3、填写参数配置

4、填好参数后进行测试

5、复制SDK示例代码
