/// warning | Uyarı

Bir *path operation* içinde birden fazla `File` ve `Form` parametresi tanımlayabilirsiniz; ancak request'in body'si `application/json` yerine `multipart/form-data` ile encode edileceği için, JSON olarak almayı beklediğiniz `Body` alanlarını aynı anda tanımlayamazsınız.

Bu **FastAPI** kısıtı değildir; HTTP protokolünün bir parçasıdır.

/// tip

上面的应用程序是一个最小和简单的示例，用于演示如何处理和向多个 WebSocket 连接广播消息。

但请记住，由于所有内容都在内存中以单个列表的形式处理，因此它只能在进程运行时工作，并且只能使用单个进程。

如果您需要与 FastAPI 集成更简单但更强大的功能，支持 Redis、PostgreSQL 或其他功能，请查看 [encode/broadcaster](https://github.com/encode/broadcaster)。

        // Directory-specific data: 20 bytes (CacheScope(4) + MaxCacheAge(8) + Flags(4) + NotificationFilter(4))
        return 16 + 4 + 4 + 32 + 20;
    }

    @Override
    public int encode(byte[] buffer, int offset) {
        int start = offset;

        // Write context header
        SMBUtil.writeInt4(0, buffer, offset); // Next (offset to next context, 0 for last)
        offset += 4;

If you need something easy to integrate with FastAPI but that is more robust, supported by Redis, PostgreSQL or others, check [encode/broadcaster](https://github.com/encode/broadcaster).
