制作自定义鳄梨酱 Web 应用程序所需的配置

如何解决制作自定义鳄梨酱 Web 应用程序所需的配置

我正在制作我自己的定制 Web 应用程序，它将取代 guacamole Web 应用程序前端。我正在关注 guacamole 手册，根据我们需要一个 index.html，另一个是 servlet，它是一个扩展 GuacamoleHTTPTunnelServlet 的类。 index.html 页面获取虚拟机的凭据以对用户进行身份验证，并在后台进入 guacamole 服务器并进行身份验证并在建立连接时提供相应的虚拟机。

Servlet：doConnect() 函数返回一个 GuacamoleTunnel，它为 GuacamoleHTTPTunnelServlet 提供了一个持久的通信通道，用于在与 guacd 交谈并使用一些任意远程桌面协议启动与某个任意远程桌面的连接时使用。在我们的简单隧道中，此配置将被硬编码，并且不会尝试任何身份验证。

package org.apache.guacamole.net.example;

import javax.servlet.http.HttpServletRequest;
import org.apache.guacamole.GuacamoleException;
import org.apache.guacamole.net.GuacamoleSocket;
import org.apache.guacamole.net.GuacamoleTunnel;
import org.apache.guacamole.net.InetGuacamoleSocket;
import org.apache.guacamole.net.SimpleGuacamoleTunnel;
import org.apache.guacamole.protocol.ConfiguredGuacamoleSocket;
import org.apache.guacamole.protocol.GuacamoleConfiguration;
import org.apache.guacamole.servlet.GuacamoleHTTPTunnelServlet;

public class TutorialGuacamoleTunnelServlet
    extends GuacamoleHTTPTunnelServlet {

    @Override
    protected GuacamoleTunnel doConnect(HttpServletRequest request)
        throws GuacamoleException {

        // Create our configuration
        GuacamoleConfiguration config = new GuacamoleConfiguration();
        config.setProtocol("vnc");
        config.setParameter("hostname","localhost");
        config.setParameter("port","5901");
        config.setParameter("password","potato");

        // Connect to guacd - everything is hard-coded here.
        GuacamoleSocket socket = new ConfiguredGuacamoleSocket(
                new InetGuacamoleSocket("localhost",4822),config
        );

        // Return a new tunnel which uses the connected socket
        return new SimpleGuacamoleTunnel(socket);;

    }

}
