public NanoWSD(java.lang.String hostname,
               int port)

Method Detail

encodeBase64

private static java.lang.String encodeBase64(byte[] buf)

Translates the specified byte array into Base64 string.

Android has android.util.Base64, sun has sun.misc.Base64Encoder, Java 8 hast java.util.Base64, I have this from stackoverflow: http://stackoverflow.com/a/4265472

Parameters:

buf - the byte array (not null)

Returns:

the translated Base64 string (not null)

makeAcceptKey

public static java.lang.String makeAcceptKey(java.lang.String key)
                                      throws java.security.NoSuchAlgorithmException

Throws:

java.security.NoSuchAlgorithmException

isWebSocketConnectionHeader

private boolean isWebSocketConnectionHeader(java.util.Map<java.lang.String,java.lang.String> headers)

isWebsocketRequested

protected boolean isWebsocketRequested(NanoHTTPD.IHTTPSession session)

openWebSocket

protected abstract NanoWSD.WebSocket openWebSocket(NanoHTTPD.IHTTPSession handshake)

serve

public NanoHTTPD.Response serve(NanoHTTPD.IHTTPSession session)

Description copied from class: NanoHTTPD

Override this to customize the server.

(By default, this returns a 404 "Not Found" plain text error response.)

Overrides:

serve in class NanoHTTPD

Parameters:

session - The HTTP session

Returns:

HTTP response, see class Response for details

serveHttp

protected NanoHTTPD.Response serveHttp(NanoHTTPD.IHTTPSession session)

useGzipWhenAccepted

protected boolean useGzipWhenAccepted(NanoHTTPD.Response r)

not all websockets implementations accept gzip compression.

Overrides:

useGzipWhenAccepted in class NanoHTTPD

Returns:

true if the gzip compression should be used if the client accespts it. Default this option is on for text content and off for everything. Override this for custom semantics.
