Example 96 with DefaultHttp2Headers

use of io.netty.handler.codec.http2.DefaultHttp2Headers in project netty by netty.

the class HelloWorldHttp2Handler method sendResponse.

/**
 * Sends a "Hello World" DATA frame to the client.
 */
private static void sendResponse(ChannelHandlerContext ctx, Http2FrameStream stream, ByteBuf payload) {
    // Send a frame for the response status
    Http2Headers headers = new DefaultHttp2Headers().status(OK.codeAsText());

}

Example 97 with DefaultHttp2Headers

use of io.netty.handler.codec.http2.DefaultHttp2Headers in project netty by netty.

the class HelloWorldHttp2Handler method sendResponse.

/**
 * Sends a "Hello World" DATA frame to the client.
 */

    // Send a frame for the response status
