newHandshaker

public static WebSocketClientHandshaker newHandshaker(java.net.URI webSocketURL,
                                                      WebSocketVersion version,

                                                      HttpHeaders customHeaders)

Creates a new handshaker.

参数:

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

version - Version of web socket specification to use to connect to the server

subprotocol - Sub protocol request sent to the server. Null if no sub-protocol support is required.

allowExtensions - Allow extensions to be used in the reserved bits of the web socket frame

customHeaders - Custom HTTP headers to send during the handshake

Creates a new handshaker.

参数:

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

version - Version of web socket specification to use to connect to the server

subprotocol - Sub protocol request sent to the server. Null if no sub-protocol support is required.

allowExtensions - Allow extensions to be used in the reserved bits of the web socket frame

customHeaders - Custom HTTP headers to send during the handshake

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

performMasking - Whether to mask all written websocket frames. This must be set to true in order to be fully compatible with the websocket specifications. Client applications that communicate with a non-standard server which doesn't require masking might set this to false to achieve a higher performance.

allowMaskMismatch - When set to true, frames which are not masked properly according to the standard will still be accepted.
