我的簡單java HTTPS服務器僅適用於localhost

[英]My simple java HTTPS server only works for localhost

我有一個用Java實現的簡單HTTPS測試服務器,如下所示。 它接受客戶端連接並發回一段有關套接字的文本。 問題是它使用https://localhost:8888在瀏覽器上本地工作,但是當我使用我的機器的真實IP(129.46.xx.xx:8888)時,它不適用於遠程瀏覽器。 問題來自哪里? 測試時,不要忘記生成樣本證書並提供以下信息。

編輯 :有趣的是,當我在Ubuntu 12.04上運行它時,我可以連接到它。 但不是在Windows上運行時!

   private static void printSocketInfo(SSLSocket s) {
      System.out.println("Server socket class: "+s.getClass());

   }
   private static void printServerSocketInfo(SSLServerSocket s) {
      System.out.println("Server socket class: "+s.getClass());
      System.out.println("   Socker address = "
         +s.getInetAddress().toString());
      System.out.println("   Socker port = "
         +s.getLocalPort());
      System.out.println("   Need client authentication = "
         +s.getNeedClientAuth());
      System.out.println("   Want client authentication = "
         +s.getWantClientAuth());
      System.out.println("   Use client mode = "
         +s.getUseClientMode());
   } 
}

這是printServerSocketInfo()方法顯示的內容:

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

這是本地瀏覽器顯示的內容:

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
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36 OPR/22.0.1471.50 (Edition Campaign 38)
Accept-Encoding: gzip,deflate,lzma,sdch
Accept-Language: en-US,en;q=0.8

嘗試像這樣創建服務器套接字:

SSLServerSocket s = (SSLServerSocket) ssf.createServerSocket(8888, 0, null);

作為最后一個參數的null應該告訴服務器套接字工廠創建一個綁定到所有網絡接口的套接字。

這是該方法特定版本的javadoc鏈接
