WebSocketServerHandshaker00

public WebSocketServerHandshaker00(java.lang.String webSocketURL,
                           java.lang.String subprotocols,
                           int maxFramePayloadLength)

Constructor specifying the destination web socket location

参数:

webSocketURL - URL for web socket communications. e.g "ws://myhost.com/mypath". Subsequent web socket frames will be sent to this URL.

subprotocols - CSV of supported protocols

maxFramePayloadLength - Maximum allowable frame payload length. Setting this value to your application's requirement may reduce denial of service attacks using long data frames.

newHandshakeResponse

protected FullHttpResponse newHandshakeResponse(FullHttpRequest req,
                                    HttpHeaders headers)

Handle the web socket handshake for the web socket specification HyBi version 0 and lower. This standard is really a rehash of hixie-76 and hixie-75.

 Upgrade: WebSocket
 Connection: Upgrade
 Host: example.com
 Origin: http://example.com
 Sec-WebSocket-Protocol: chat, sample
 Sec-WebSocket-Key1: 4 @1  46546xW%0l 1 5
 Sec-WebSocket-Key2: 12998 5 Y3 1  .P00

 ^n:ds[4U
 

Server response:

 Upgrade: WebSocket
 Connection: Upgrade
 Sec-WebSocket-Origin: http://example.com
 Sec-WebSocket-Location: ws://example.com/demo
 Sec-WebSocket-Protocol: sample
