```
public WebSocket13FrameDecoder(boolean expectMaskedFrames,
                               boolean allowExtensions,
                               int maxFramePayloadLength)
```
    构造函数
    
    参数
    
    expectMaskedFrames - Web套接字服务器必须将其设置为真正处理的传入掩码有效内容。客户端实现必须将其设置为false。
    
    allowExtensions - 允许使用或不使用保留扩展位的标志
    
    maxFramePayloadLength - 帧有效负载的最大长度。将其设置为适合您的应用程序有助于检查拒绝服务攻击。
