快速入门

创建springboot工程,勾选web开发依赖
定义请求处理类helloController,定义请求方法
运行启动类,测试

http协议

请求协议

请求行
请求头
请求体

HttpServletRequest

package com.itheima;
 
 
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
public class RequestController {
    @RequestMapping("/request")
    public String request(HttpServletRequest request ){
        String method = request.getMethod();
        System.out.println( "method : "+ method);
 
        //获取请求url地址
        String url = request.getRequestURL().toString();// http://localhost:8080/request
        System.out.println("url : "+ url);
        String uri = request.getRequestURI();// /request
        System.out.println("uri : "+ uri);
 
        //获取请求协议
        String protocol = request.getProtocol();// HTTP/1.1
        System.out.println("protocol : "+ protocol);
 
         //获取请求参数
        String name = request.getParameter( "name");
        System.out.println("name : "+ name);
 
        //获取请求头
         String header = request.getHeader("Accept");
         System.out.println("header : "+ header);
        return "Received request with method: " + method + ", name: " + name;
    }
