比如对于例子中的代码：

 public void init(HttpProxyInterceptPipeline pipeline) {
            pipeline.addLast(new HttpProxyIntercept() {
                @Override
                public void beforeRequest(Channel clientChannel, HttpRequest httpRequest,
                                            HttpProxyInterceptPipeline pipeline) throws Exception {
                    //匹配到百度的请求转发到淘宝
                    if (HttpUtil.checkUrl(httpRequest, "^www.baidu.com$")) {
                        pipeline.getRequestProto().setHost("www.taobao.com");
                        pipeline.getRequestProto().setPort(443);
                        pipeline.getRequestProto().setSsl(true);
                    }
//                                if (HttpUtil.checkUrl(httpRequest, "^www.baidu.com$")) {
//                                    httpRequest.headers().set(HttpHeaderNames.HOST, "www.taobao.com");
//                                    pipeline.getRequestProto().setHost("113.141.190.106");
//                                    pipeline.getRequestProto().setPort(443);
//                                    pipeline.getRequestProto().setSsl(true);
//                                }
                    pipeline.beforeRequest(clientChannel, httpRequest);
                }
            });

我改成这样（将taobao域名改成ip）

                            public void beforeRequest(Channel clientChannel, HttpRequest httpRequest,
                                                      HttpProxyInterceptPipeline pipeline) throws Exception {
                                //匹配到百度的请求转发到淘宝
//                                if (HttpUtil.checkUrl(httpRequest, "^www.baidu.com$")) {
//                                    pipeline.getRequestProto().setHost("www.taobao.com");
//                                    pipeline.getRequestProto().setPort(443);
//                                    pipeline.getRequestProto().setSsl(true);
//                                }
                                if (HttpUtil.checkUrl(httpRequest, "^www.baidu.com$")) {
                                    httpRequest.headers().set(HttpHeaderNames.HOST, "www.taobao.com");
                                    pipeline.getRequestProto().setHost("113.141.190.106");  //这个ip是我ping www.taobao.com得到的ip
                                    pipeline.getRequestProto().setPort(443);
                                    pipeline.getRequestProto().setSsl(true);
                                }
                                pipeline.beforeRequest(clientChannel, httpRequest);
                            }
                        });

当改成第二种方式（通过ip）的方式，就不能访问成功，返回的是：

tester@tester tester-tester % curl -k -x 127.0.0.1:9999 https://www.baidu.com
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html>
<head><title>403 Forbidden</title></head>
<body>
<h1>403 Forbidden</h1>
<p>You don't have permission to access the URL on this server.<hr/>Powered by Tengine</body>
</html>
tester@tester tester-tester %

我是有这样的需求，需要从将域名转发到不同的nginx对应的ip（都是https的协议），所以请教一下，非常感谢~

现在的实现还支持不了这个场景，等我明天改下

不过我看了下你的需求，如果你的后端服务如果本来就是可以用ip访问的应该就没问题

感谢回复。我的服务在浏览器中后端服务（通过nginx反向代理转发的）直接通过ip访问，nginx会强制跳转到域名。命令行curl返回的错误码是405 Not Allowed。
我尝试过在beforeConnect修改远程ip地址，但是没有成功（我对这个逻辑确实也不太熟，最近刚刚开始使用才了解的）。
