light-netty-client

Light-netty-client is a light framework for rapid development of asynchronous clients based on netty 4.x.

The sample code for sending get request:

String getUrl = "http://www.baidu.com:80";
NettyHttpRequest request = new NettyHttpRequest();
request.header(HttpHeaders.Names.CONTENT_TYPE, "text/json; charset=GBK").uri(getUrl);

NettyHttpClient client = new NettyHttpClient.ConfigBuilder()
    .maxIdleTimeInMilliSecondes(200 * 1000)
    .connectTimeOutInMilliSecondes(30 * 1000).build();

NettyHttpResponseFuture responseFuture = client.doGet(request);
NettyHttpResponse result = (NettyHttpResponse) responseFuture.get();
client.close();

The sample code for sending post request:

String postUrl = "http://www.xxx.com:8080/testPost";
String postContent = "";//json format
NettyHttpRequest request = new NettyHttpRequest();
request.header(HttpHeaders.Names.CONTENT_TYPE, "text/json; charset=GBK").uri(postUrl).content(
    postContent, null);

NettyHttpClient client = new NettyHttpClient.ConfigBuilder()
    .maxIdleTimeInMilliSecondes(200 * 1000)
    .connectTimeOutInMilliSecondes(30 * 1000)
    .build();

NettyHttpResponseFuture responseFuture = client.doPost(request);
NettyHttpResponse result = (NettyHttpResponse) responseFuture.get();
client.close();

You can config the maximum number of channels to allow in the channel pool like this:

Map<String, Integer> maxPerRoute = new HashMap<String, Integer>();
maxPerRoute.put("www.baidu.com:80", 100);

NettyHttpClient client = new NettyHttpClient.ConfigBuilder()
    .maxIdleTimeInMilliSecondes(200 * 1000)
    .connectTimeOutInMilliSecondes(30 * 1000)
    .maxPerRoute(maxPerRoute)
    .build();

If you not config this, the default value is 200.
