## Check it

Now, every request under the path `/v1/` will be handled by the Flask application.

And the rest will be handled by **FastAPI**.

If you run it and go to <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a> you will see the response from Flask:

```txt
Hello, World from Flask!
```

	return restClient.Call("/v1/rlock", args)
}

func (restClient *ReconnectRESTClient) Lock(ctx context.Context, args LockArgs) (status bool, err error) {
	return restClient.Call("/v1/lock", args)
}

func (restClient *ReconnectRESTClient) RUnlock(ctx context.Context, args LockArgs) (status bool, err error) {
	return restClient.Call("/v1/runlock", args)
}

	"github.com/minio/minio/internal/kms"
	"github.com/minio/minio/internal/logger"
	"github.com/minio/pkg/v3/policy"
)

// KMSStatusHandler - GET /minio/kms/v1/status
func (a kmsAPIHandlers) KMSStatusHandler(w http.ResponseWriter, r *http.Request) {
	ctx := newContext(r, w, "KMSStatus")
	defer logger.AuditLog(ctx, w, r, mustGetClaimsFromToken(r))

                                    }
                                )
                                | IsDict(
                                    # TODO: remove when deprecating Pydantic v1
                                    {

                                    }
                                )
                                | IsDict(
                                    # TODO: remove when deprecating Pydantic v1
                                    {
                                        "$ref": "#/components/schemas/Body_create_file_files__post"
                                    }
                                )

## 检查

现在，所有定义在 `/v1/` 路径下的请求将会被 Flask 应用处理。

其余的请求则会被 **FastAPI** 处理。

如果您使用 Uvicorn 运行应用实例并且访问 <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a>，您将会看到由 Flask 返回的响应：

```txt
Hello, World from Flask!
```
