/// note | Technical Details

You could also use `from starlette import status`.

**FastAPI** provides the same `starlette.status` as `fastapi.status` just as a convenience for you, the developer. But it comes directly from Starlette.

///

## Changing the default { #changing-the-default }

# Additional Status Codes { #additional-status-codes }

By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

## Additional status codes { #additional-status-codes_1 }

# Response - Change Status Code { #response-change-status-code }

You probably read before that you can set a default [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank}.

But in some cases you need to return a different status code than the default.

## Use case { #use-case }

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

			_, err = globalIAMSys.SetUserStatus(ctx, change.AccessKey, userReq.Status)
		} else {

**FastAPI** предоставляет тот же `starlette.responses` через `fastapi.responses` просто для вашего удобства, как разработчика. Но большинство доступных Response-классов поступают напрямую из Starlette. То же самое касается и `status`.

## OpenAPI и документация API

# Response - Изменение cтатус кода

Вы, вероятно, уже читали о том, что можно установить [Состояние ответа по умолчанию](../tutorial/response-status-code.md){.internal-link target=_blank}.

Но в некоторых случаях вам нужно вернуть код состояния, отличный от установленного по умолчанию.

## Пример использования

Например, представьте, что вы хотите возвращать HTTP код состояния "OK" `200` по умолчанию.

		// Call the ServeHTTP to executes the registered handler.
		apiRouter.ServeHTTP(rec, req)
		// Assert the response code with the expected status.
		if rec.Code != testCase.expectedRespStatus {
			t.Errorf("Test %d: MinIO %s: Expected the response status to be `%d`, but instead found `%d`", i, instanceType, testCase.expectedRespStatus, rec.Code)
		}

		// read the response body.

func (rs *ReplicationState) Equal(o ReplicationState) bool {
	return rs.ReplicaStatus == o.ReplicaStatus &&
		rs.ReplicationStatusInternal == o.ReplicationStatusInternal &&
		rs.VersionPurgeStatusInternal == o.VersionPurgeStatusInternal
}

// CompositeReplicationStatus returns overall replication status for the object version being replicated.

    }

    /**
     * Represents the status of an API response.

    public enum Status {
        /** Successful response status. */
        OK(0),
        /** Bad request status indicating client error. */
        BAD_REQUEST(1),
        /** System error status indicating server error. */
        SYSTEM_ERROR(2),
        /** Unauthorized status indicating authentication failure. */
