通過Go SDK V2調用DeleteVectorIndex介面刪除指定的向量索引。刪除操作無法復原，請謹慎操作。
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。
API | Action | 說明 |
DeleteVectorIndex |
| 刪除向量索引。 |
方法定義
func (c *VectorsClient) DeleteVectorIndex(ctx context.Context, request *DeleteVectorIndexRequest, optFns ...func(*oss.Options)) (*DeleteVectorIndexResult, error)請求參數列表
參數名 | 類型 | 說明 |
ctx | context.Context | 請求上下文。 |
request | *DeleteVectorIndexRequest | 佈建要求參數，具體請參見DeleteVectorIndexRequest |
optFns | ...func(*Options) | （可選）介面級的配置參數, 請參見Options |
傳回值列表
參數名 | 類型 | 說明 |
result | *DeleteVectorIndexResult | 傳回值，當 err 為nil 時有效，具體請參見DeleteVectorIndexResult |
err | error | 錯誤資訊，如果操作成功則為nil |
