Guacamole 鳄梨酱，无键盘

我正在使用Guacamole

0.9.12-Cubating

——在服务器端扩展

GuacamoleHTTPTunnelServlet

，在客户端使用官方JavaScript代码。Guacamole服务器是从源代码编译的，运行在Ubuntu 17.04上

SSH连接已成功建立，但在15秒后断开连接。键盘和鼠标都不工作

客户端JavaScript与文档中的相同-

当我重写servlet中的方法时，它们向我显示按键指向它。所以问题可能在servlet和guacd之间的某个地方

@Override
protected void doWrite(HttpServletRequest request, HttpServletResponse response, String tunnelUUID) throws GuacamoleException {
        LOGGER.debug("Do WRITE to session " + tunnelUUID);
        super.doWrite(request, response, tunnelUUID);
    }

@Override
protected void doRead(HttpServletRequest request, HttpServletResponse response, String tunnelUUID) throws GuacamoleException {
        LOGGER.debug("Do read to session " + tunnelUUID);
        super.doRead(request, response, tunnelUUID);
    }

已建立连接，但没有任何按键正在工作：

谢谢。

问题出在Spring Boot中，正如上面讨论的-

解决方案是创建自己的

HiddenHttpMethodFilter实现：

@Configuration
public class GuacamoleServletConfiguration {

    @Bean
    public GuacamoleServlet guacamoleTunnelServlet() {
        return new GuacamoleServlet();
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        ServletRegistrationBean bean = new ServletRegistrationBean(guacamoleTunnelServlet(), "/remote/tunnel");
        bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
        return bean;
    }

    @Bean
    public HiddenHttpMethodFilter hiddenHttpMethodFilter() {
        return new HiddenHttpMethodFilter() {
            @Override
            protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
                if ("POST".equals(request.getMethod()) && request.getRequestURI().startsWith("/remote/tunnel")) {
                    filterChain.doFilter(request, response);
                } else {
                    super.doFilterInternal(request, response, filterChain);
                }
            }
        };
    }
}
