本地示例：

package org.example.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import javax.servlet.http.Cookie;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.util.Enumeration;
    
    @RestController
    public class ParamController
    {
        @RequestMapping(value = "/test1")                     //获取请求行数据
        public void test1(HttpServletRequest request)
        {
            System.out.println(request.getMethod());   //获取请求方式；
    
            System.out.println(request.getContextPath());  //获取虚拟目录
    
            System.out.println(request.getServletPath());  //获取servlet路径
    
            System.out.println(request.getQueryString());   //获取请求参数
    
            System.out.println(request.getRequestURI());   //获取请求URI，部分
    
            System.out.println(request.getRequestURL());   //获取请求URI，全部
    
    
        }
    
    
        @RequestMapping(value = "/test2")                   //获取请求头方法一
        public void test2(HttpServletRequest request)
        {
            System.out.println(request.getHeader("accept"));
    
    
    
        }
    
    
        @RequestMapping(value = "/test3")                   //获取请求头方法二
        public void test3(HttpServletRequest request)
        {
    
            Enumeration<String> headerNames = request.getHeaderNames();
            while (headerNames.hasMoreElements())             //读取请求消息头
            {
                String name = headerNames.nextElement();
                String value = request.getHeader(name);
    
                System.out.println(name + "        "+value);
            }
    
    
        }
    }
