对象存储 OSS设置生命周期规则

详细解答可以参考官方帮助文档

通过Client.SetBucketLifecycle来设置生命周期规则：

    import "github.com/aliyun/aliyun-oss-go-sdk/oss"

    client, err := oss.New("Endpoint", "AccessKeyId", "AccessKeySecret")
    if err != nil {
        // HandleError(err)
    }

    // id:"rule1", enable:true, prefix:"foo/", expiry:Days 3
    rule1 := oss.BuildLifecycleRuleByDays("rule1", "foo/", true, 3)
    // id:"rule2", enable:false, prefix:"bar/", expiry:Date 2016/1/1
    rule2 := oss.BuildLifecycleRuleByDate("rule2", "bar/", true, 2016, 1, 1)
    rules := []oss.LifecycleRule{rule1, rule2}

    err = client.SetBucketLifecycle("my-bucket", rules)
    if err != nil {
        // HandleError(err)
    }
