我的简单java HTTPS服务器仅适用于localhost [英] My simple java HTTPS server only works for localhost
问题描述
我有一个用Java实现的简单HTTPS测试服务器，如下所示。它接受客户端连接并发回一段有关套接字的文本。问题是它使用 https：// localhost：8888 在浏览器上本地工作，但是当我使用机器的真实IP时，它不适用于远程浏览器（129.46.xx.xx：8888）。问题来自哪里？测试时，不要忘记生成示例证书并提供以下信息。
I have a simple HTTPS test server implemented in Java, as shown below. It accepts client connections and sends back a piece of text about the socket. The problem is that it works locally on a browser using https://localhost:8888, but it does not work with remote browsers, when I use the real IP of my machine (129.46.xx.xx:8888). Where is the problem coming from? When testing, don't forget to generate a sample certificate and provide the info below.
编辑：有趣的是，当我在Ubuntu上运行它时12.04，我可以连接到它。但不是在Windows上运行时！
EDIT: Interestingly, when I run it on Ubuntu 12.04, I can connect to it. But not when running on windows!

System.out.println(" Want client authentication = "
+s.getWantClientAuth());
System.out.println(" Use client mode = "

}
}
这是 printServerSocketInfo（ ）方法显示：
Server started:
Server socket class: class sun.security.ssl.SSLServerSocketImpl
Socker address = 0.0.0.0/0.0.0.0
Socker port = 8888
Need client authentication = false
Want client authentication = false
Use client mode = false
这是本地浏览器显示的内容：
This is what the local browser is showing:
Connection #: 3
GET / HTTP/1.1
Host: localhost:8888
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8

推荐答案
尝试像这样创建服务器套接字：
Try creating your server socket like this:
SSLServerSocket s = (SSLServerSocket) ssf.createServerSocket(8888, 0, null);
null 作为最后一个参数应该告诉服务器套接字工厂创建一个绑定到所有网络接口的套接字。
The null as the last argument should tell the server socket factory to create a socket that is bound to all network interfaces.
这是一个指向该特定版本的javadoc 的链接方法。
