我有一个调用Netty服务器的Apache HttpComponents客户端。该代码是一个简单的测试。Netty服务器和HttpComponents客户端
ExecutorService threadpool = Executors.newFixedThreadPool(2);
Async async = Async.newInstance().use(threadpool);
Request[] requests = new Request[] {
ContentType.APPLICATION_JSON),
Request.Post("http://localhost:9090/print").bodyString(getJSon(), ContentType.APPLICATION_JSON)
};
Queue<Future<Content>> queue = new LinkedList<Future<Content>>();
// Execute requests asynchronously
for (final Request request: requests) {
Future<Content> future = async.execute(request, new FutureCallback<Content>() {
public void failed(final Exception ex) {
logger.info(ex.getMessage() + ": " + request);
}
public void completed(final Content content) {
logger.info("Request completed: " + request);
}
public void cancelled() {
logger.info("Request cancelled: " + request);
}
});
queue.add(future);
}
while(!queue.isEmpty()) {
Future<Content> future = queue.remove();
try {
Content c = future.get();
logger.info("Response " + c.asString());
} catch (ExecutionException ex) {
logger.info("ExecutionException [" + getExceptionAsString(ex) + "]");
}
}
这是Netty的服务器的 writeResponse方法。
private boolean writeResponse(HttpObject currentObj, ChannelHandlerContext ctx) {
boolean keepAlive = isKeepAlive(request);
Response respond = new Response();
ByteBuf bufResponse = Unpooled.copiedBuffer(respond.getJSon(),
CharsetUtil.UTF_8);
logger.info("Response is [" + respond.getJSon() + "]");
FullHttpResponse response = new DefaultFullHttpResponse(
HTTP_1_1, currentObj.getDecoderResult().isSuccess()? OK : BAD_REQUEST,
Unpooled.copiedBuffer(bufResponse.toString(), CharsetUtil.UTF_8));
response.headers().set(CONTENT_TYPE, "application/json; charset=UTF-8");
ctx.writeAndFlush(response);
return keepAlive;
}
对记录器的调用按预期工作。它正在返回一个我正在打印的JSON对象。
但是不调用HttpComponents客户端中的回调方法。看起来服务器没有返回到客户端。
Netty服务器似乎工作，但我不知道为什么客户端不会干净地返回。任何人都可以帮我发现错误吗？我正在eclipse中进行测试。
