Question

在jetty 9.2 getCurrentHttpChannel上有一个HttpChannel方法，我们将其用作HttpChannel.getCurrentHttpChannel().getHttpConfiguration();

我现在想要转换为Jetty 9.3但是该方法缺失了，我在文档等中找不到任何已更改的引用。 9.3中是否有等价物？

Answer 1

在Jetty 9.3中，可以使用以下命令：

HttpConnection.getCurrentConnection().getHttpChannel().getHttpConfiguration();

Answer 2

几乎所有Jetty内部的Thread Local访问方法都已被删除，因为它们在HTTP / 2，WebSocket和各种其他客户端上下文中使用时无效。

如果您需要访问Jetty的内部，则必须在ServletContext之外执行此操作。

例如：SecuredRedirectHandler

package org.eclipse.jetty.server.handler;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.eclipse.jetty.http.HttpStatus;
import org.eclipse.jetty.server.HttpChannel;
import org.eclipse.jetty.server.HttpConfiguration;
import org.eclipse.jetty.server.Request;
import org.eclipse.jetty.util.URIUtil;

/**
 * Secured Redirect Handler
 * <p>
 * Using information present in the {@link HttpConfiguration}, will attempt to redirect to the {@link HttpConfiguration#getSecureScheme()} and
 * {@link HttpConfiguration#getSecurePort()} for any request that {@link HttpServletRequest#isSecure()} == false.
 */
public class SecuredRedirectHandler extends AbstractHandler
{
    @Override
    public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
    {
        HttpChannel channel = baseRequest.getHttpChannel();
        if (baseRequest.isSecure() || (channel == null))
        {
            // nothing to do
            return;
        }

        HttpConfiguration httpConfig = channel.getHttpConfiguration();
        if (httpConfig == null)
        {
            // no config, show error
            response.sendError(HttpStatus.FORBIDDEN_403,"No http configuration available");
            return;
        }

        if (httpConfig.getSecurePort() > 0)
        {
            String scheme = httpConfig.getSecureScheme();
            int port = httpConfig.getSecurePort();

            String url = URIUtil.newURI(scheme,baseRequest.getServerName(),port,baseRequest.getRequestURI(),baseRequest.getQueryString());
            response.setContentLength(0);
            response.sendRedirect(url);
        }
        else
        {
            response.sendError(HttpStatus.FORBIDDEN_403,"Not Secure");
        }

        baseRequest.setHandled(true);
    }
}

什么是HttpChannel.getCurrentHttpChannel（）的等效性.getHttpConfiguration（）;在码头9.3
