客戶端的Netty HTTP認證

Question

看看我下面寫的測試代碼。 使用純java我設置了一個Authenticator並進行URI調用以獲取一些xml數據並將其轉換為一個對象。

我編寫了下面的代碼來測試hotpotato （ netty ）與純java（沒有流水線）的性能。

問題是，我無法弄清楚如何使用hotpotato或netty驗證我的請求，其中任何一個的代碼都是可以接受的，我只想測試性能差異（即查看將在5秒內執行多少請求）。

    public static void main(String[] args) throws Exception {
        Authenticator.setDefault(new MyAuthenticator("DummyUser", "DummyPassword"));

        int timeToTestFor = 5000; //5 seconds;
        int count = 0;
        System.out.println("Start time");
        long starttime = System.currentTimeMillis();
        do {
            URL url = new URL(
                    "http://example.com/rest/GetData.ashx?what=pizza&where=new%20york&visitorId=12345&sessionId=123456");

            SearchResultsDocument doc = SearchResultsDocument.Factory.parse(url);
            count++;
        } while (System.currentTimeMillis() - starttime < timeToTestFor);
        System.out.println("DONE Total count=" + count);

        System.out.println("Netty/Hotpotatoe Start time");
        count = 0;
        starttime = System.currentTimeMillis();
        do {
            // Create & initialise the client
            HttpClient client = new DefaultHttpClient();
            client.init();


            // Setup the request
            HttpRequest request = new DefaultHttpRequest(HttpVersion.HTTP_1_0,
                    HttpMethod.GET, "/rest/GetData.ashx?what=pizza&where=new%20york&visitorId=12345&sessionId=123456");

            // Execute the request, turning the result into a String
            HttpRequestFuture future = client.execute("example.com", 80, request,
                    new BodyAsStringProcessor());
            future.awaitUninterruptibly();
            // Print some details about the request
            System.out.println("A >> " + future);

            // If response was >= 200 and <= 299, print the body
            if (future.isSuccessfulResponse()) {
                System.out.println("B >> "+future.getProcessedResult());
            }

            // Cleanup
            client.terminate();
            count++;
        } while (System.currentTimeMillis() - starttime < timeToTestFor);
        System.out.println("DONE Total count=" + count);
    }

以下是僅使用Netty進行基本身份驗證的工作示例。 使用Jetty作為需要基本身份驗證的服務器進行測試。

    ClientBootstrap client = new ClientBootstrap(
            new NioClientSocketChannelFactory(

                    Executors.newCachedThreadPool()));

    client.setPipelineFactory(new ChannelPipelineFactory() {

        @Override
        public ChannelPipeline getPipeline() throws Exception {
            ChannelPipeline pipeline = Channels.pipeline();
            pipeline.addLast("codec", new HttpClientCodec());
            pipeline.addLast("aggregator", new HttpChunkAggregator(5242880));
            pipeline.addLast("authHandler", new ClientMessageHandler());
            return pipeline;
        }
    });

    DefaultHttpRequest request = new DefaultHttpRequest(HttpVersion.HTTP_1_1, HttpMethod.GET, URI);

    request.addHeader(HttpHeaders.Names.HOST, HOST);

    String authString = USERNAME + ":" + PASSWORD;
    ChannelBuffer authChannelBuffer = ChannelBuffers.copiedBuffer(authString, CharsetUtil.UTF_8);
    ChannelBuffer encodedAuthChannelBuffer = Base64.encode(authChannelBuffer);
    request.addHeader(HttpHeaders.Names.AUTHORIZATION, encodedAuthChannelBuffer.toString(CharsetUtil.UTF_8));

    client.connect(new InetSocketAddress(HOST, PORT)).awaitUninterruptibly().getChannel()
            .write(request).awaitUninterruptibly();

}

public static class ClientMessageHandler extends SimpleChannelHandler {
    @Override
    public void exceptionCaught(ChannelHandlerContext ctx, ExceptionEvent e) throws Exception {
        e.getCause().printStackTrace();
    }

    @Override

        HttpResponse httpResponse = (HttpResponse) e.getMessage();
        String json = httpResponse.getContent().toString(CharsetUtil.UTF_8);
        System.out.println(json);
    }
}
