RxNetty是Netty的Reactive扩展

RxNetty是将Reactive异步机制(类似Node.js)带入了Netty.

下面使用代码:


import io.netty.buffer.ByteBuf;
import io.netty.handler.codec.http.HttpResponseStatus;
import io.reactivex.netty.RxNetty;
import io.reactivex.netty.protocol.http.server.HttpServer;

import java.nio.charset.Charset;

public final class RxNettyExample {

public static void main(String... args) throws InterruptedException {
HttpServer<ByteBuf, ByteBuf> server = RxNetty.createHttpServer(8080, (request, response) -> {
System.out.println("Server => Request: " + request.getPath());
try {
if (
"/error".equals(request.getPath())) {
throw new RuntimeException(
"forced error");
}
response.setStatus(HttpResponseStatus.OK);
response.writeString(
"Path Requested =>: " + request.getPath() + '\n');
return response.close();
} catch (Throwable e) {
System.err.println(
"Server => Error [" + request.getPath() + "] => " + e);
response.setStatus(HttpResponseStatus.BAD_REQUEST);
response.writeString(
"Error 500: Bad Request\n");
return response.close();
}
});

server.start();

RxNetty.createHttpGet(
"http://localhost:8080/")
.flatMap(response -> response.getContent())
.map(data ->
"Client => " + data.toString(Charset.defaultCharset()))
.toBlocking().forEach(System.out::println);

RxNetty.createHttpGet(
"http://localhost:8080/error")
.flatMap(response -> response.getContent())
.map(data ->
"Client => " + data.toString(Charset.defaultCharset()))
.toBlocking().forEach(System.out::println);

RxNetty.createHttpGet(
"http://localhost:8080/data")
.flatMap(response -> response.getContent())
.map(data ->
"Client => " + data.toString(Charset.defaultCharset()))
.toBlocking().forEach(System.out::println);

server.shutdown();
}
}


输出:


Server => Request: /
Client => Path Requested =>: /

Server => Request: /error
Server => Error [/error] => java.lang.RuntimeException: forced error
Client => Error 500: Bad Request

Server => Request: /data
Client => Path Requested =>: /data
