在使用Netty的HTTP持久连接上限制每秒的事务数（http客户端）

Question

Is there any mechanism/api by which I can control TPS hits from http client?

From HTTP client, I need to control numbers of hits to rest services (my HTTP client will hit to server in controlled manner).

Answer 1

you can close it immediately by adding a Netty's IpFilterHandler to server pipeline as the first handler. It will also stop propagating the upstream channel state events for filtered connection too.

 @ChannelHandler.Sharable
 public class FilterIPHandler extends IpFilteringHandlerImpl {
 private final Set<InetSocketAddress> deniedIP;

public filter(Set<InetSocketAddress> deniedIP) {
     this.deniedIP = deniedIP;
 }

 @Override
 protected boolean isAnAccpetedIP(ChannelHandlerContext ctx, ChannelEvent e,  InetSocketAddress inetSocketAddress) throws Exception {
       return !deniedIP.contains(inetSocketAddress);
 }
 }
