Object Storage Service：列舉向量Index（Go SDK V2）

許可權說明

阿里雲帳號預設擁有全部許可權。阿里雲帳號下的RAM使用者或RAM角色預設沒有任何許可權，需要阿里雲帳號或帳號管理員通過RAM Policy或Bucket Policy授予操作許可權。

方法定義

func (c *VectorsClient) ListVectorIndexes(ctx context.Context, request *ListVectorIndexesRequest, optFns ...func(*oss.Options)) (*ListVectorIndexesResult, error)
