权限说明

阿里云账号默认拥有全部权限。阿里云账号下的RAM用户或RAM角色默认没有任何权限，需要阿里云账号或账号管理员通过RAM Policy或Bucket Policy授予操作权限。

方法定义

func (c *VectorsClient) DeleteVectors(ctx context.Context, request *DeleteVectorsRequest, optFns ...func(*oss.Options)) (*DeleteVectorsResult, error)

	// 创建向量存储客户端
	client := vectors.NewVectorsClient(cfg)

	// 构造删除向量数据的请求
	request := &vectors.DeleteVectorsRequest{

		IndexName: oss.Ptr("index"),
		Keys: [ ]string{

			"key1", "key2",                          // 要删除的向量键列表

	// 执行删除向量数据的操作
	result, err := client.DeleteVectors(context.TODO(), request)
	if err != nil {
		log.Fatalf("failed to delete vectors %v", err)

	// 输出操作结果
	log.Printf("delete vectors result:%#v\n", result)
