WebSocketClientHandshaker

protected WebSocketClientHandshaker(java.net.URI webSocketUrl,
                         WebSocketVersion version,
                         java.lang.String subprotocol,
                         java.util.Map<java.lang.String,java.lang.String> customHeaders)

Base constructor with default values

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.

customHeaders - Map of custom headers to add to the client request

Base constructor

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 - CSV of requested subprotocol(s) sent to the server.

customHeaders - Map of custom headers to add to the client request

maxFramePayloadLength - Maximum length of a frame's payload

方法详细资料

getWebSocketUrl

public java.net.URI getWebSocketUrl()

Returns the URI to the web socket. e.g. "ws://myhost.com/path"

getVersion

public WebSocketVersion getVersion()

Version of the web socket specification that is being used

getMaxFramePayloadLength

public long getMaxFramePayloadLength()

Returns the max length for any frame's payload

isHandshakeComplete

public boolean isHandshakeComplete()

Flag to indicate if the opening handshake is complete

setHandshakeComplete

protected void setHandshakeComplete()

getExpectedSubprotocol

public java.lang.String getExpectedSubprotocol()

Returns the CSV of requested subprotocol(s) sent to the server as specified in the constructor

getActualSubprotocol

public java.lang.String getActualSubprotocol()

Returns the subprotocol response sent by the server. Only available after end of handshake. Null if no subprotocol was requested or confirmed by the server.

setActualSubprotocol

protected void setActualSubprotocol(java.lang.String actualSubprotocol)

handshake

public abstract ChannelFuture handshake(Channel channel)
                                 throws java.lang.Exception

Begins the opening handshake

参数:

channel - Channel

抛出:

java.lang.Exception

finishHandshake

public abstract void finishHandshake(Channel channel,
                   HttpResponse response)

Validates and finishes the opening handshake initiated by handshake(org.jboss.netty.channel.Channel)}.
