Tre*_*kaz 15 java https port http jetty
(我知道这是一个重复的问题,但原始的海报问错了原因.我并不是说我正确地问它,但是让我们看看.)
我们有一个运行在非标准端口号上的Web服务.尽管用户似乎能够记住端口号,但偶尔他们会输入http:而不是https:.有人问我们是否可以在该端口上提供HTTP,然后在同一端口上将它们重定向到HTTPS.这听起来很邪恶......我喜欢可用性但感觉浏览器的工作应该是这样做的吗？
我见过的一个解决方案是"在Jetty面前编写自己的代理".这个解决方案可行,但我不认为它会运行良好,因为我不相信我能编写一个与Jetty本身一样高效的代理.此外,即使代理本身有效,所有数据仍然需要额外跳跃,这无论如何都会保证减慢流量.
有比这更好的方法吗？也许Jetty本身有一些协议检测逻辑可以被楔入的地方,这将允许利用它们的速度,同时还删除代理将引入的额外跳.

更新:有关如何将单个端口重定向到HTTPS和HTTP侦听器的说明,请参阅此答案.如果由于某种原因您不使用该解决方案,请参阅以下内容:
无法在同一端口上管理来自http和https的流量.Jetty使用两个完全不同的连接器绑定到安全和不安全的端口.事实上,我遇到的每个Web服务器都将这两个协议绑定到两个完全独立的端口.
我建议可用性的一件事是使用默认端口,它完全隐藏了用户的端口.默认情况下,http使用端口80,默认情况下,https使用端口443.因此,如果您将连接器配置为分别在端口80和端口443上运行,那么您的用户不必键入端口,并且您的开发团队不会必须处理HTML,CSS,JavaScript和其他资源中的绝对路径中的端口号.
Jetty被设计为独立的Web服务器,不像旧版本的Tomcat,Apache建议在Apache HTTP服务器后运行.因此,只要您没有其他HTTP服务器正在运行,并且使用这些端口而您不能,您应该能够将Jetty配置为在默认端口上运行而不会出现任何问题.这来自经验.我们正是以这种方式运行Jetty.
最后,协议可以绑定到多个端口.因此,如果您当前在端口8080上为http运行Jetty,在8443上为https运行Jetty,则可以将这些连接器保持活动状态,并为端口80和端口443添加另外两个连接器.这样可以向应用程序的部分向后兼容使用端口号,让你有时间向前走.

对于第2和第4个连接器,唯一真正的区别是端口号.简而言之,您可以为每个连接器/协议配置多个端口,但不能为同一端口配置多个协议/连接器.
更新:截至Jetty-9.4.15.v20190215支持端口统一内置于Jetty; 看到这个答案.
这是可能的,我们已经做到了.这里的代码适用于Jetty 8; 我没有测试过Jetty 9,但这个答案有类似Jetty 9的代码.
顺便说一下,这被称为端口统一,并且使用Grizzly显然在Glassfish中得到了长期支持.
基本思想是生成一个实现org.eclipse.jetty.server.Connector,可以在客户端请求的第一个字节处查看.幸运的是,HTTP和HTTPS都让客户端开始通信.对于HTTPS(通常是TLS/SSL),第一个字节将是0x16(TLS)或>= 0x80(SSLv2).对于HTTP,第一个字节将是旧的可打印的7位ASCII.现在,根据第一个字节,Connector将生成SSL连接或普通连接.
在这里的代码中,我们利用了Jetty SslSelectChannelConnector本身扩展的事实SelectChannelConnector,并且有一个newPlainConnection()方法(调用它的超类来产生非SSL连接)以及一个newConnection()方法(产生一个SSL连接).所以我们的new Connector可以SslSelectChannelConnector在观察客户端的第一个字节后扩展并委托给其中一个方法.
不幸的是,我们需要AsyncConnection 在第一个字节可用之前创建一个实例.甚至可以在第一个字节可用之前调用该实例的某些方法.因此,我们创建一个LazyConnection implements AsyncConnection可以在以后确定它将委托给哪种连接,或者甚至在它知道之前返回一些方法的合理默认响应.
以NIO为基础,我们Connector将与之合作SocketChannel.幸运的是,我们可以扩展SocketChannel以创建一个ReadAheadSocketChannelWrapper委托给"真实" SocketChannel但可以检查和存储客户端消息的第一个字节.
一个非常hacky位.我们Connector必须覆盖的方法之一是customize(Endpoint,Request).如果我们最终以SSL为基础,Endpoint我们可以传递给我们的超类; 否则超类将抛出一个ClassCastException,但只有在传递给它的超类并在其上设置方案之后Request.所以我们传递给超类,但是当我们看到异常时撤消设置方案.
我们还覆盖isConfidential()并isIntegral()确保我们的servlet可以正确地用于HttpServletRequest.isSecure()确定是否使用了HTTP或HTTPS.
尝试从客户端读取第一个字节可能会抛出一个IOException,但我们可能不得不在IOException不期望的地方尝试这种情况,在这种情况下我们保留异常并稍后抛出它.
SocketChannelJava> = 7和Java 6中的扩展看起来不同.在后一种情况下,只需注释掉Java 6 SocketChannel没有的方法.
