Java后端基础练习|请求参数

请求参数，可以通过四种方式传递到后端

• 请求路径
• 查询参数
• 请求体
• 请求头

controller代码

package com.urfread.breaknews.core.controller;import com.urfread.breaknews.core.common.model.ResultData;
import lombok.Data;
import org.springframework.web.bind.annotation.*;/*** Class Description: A brief description of the functionality and purpose of this class.** @author urfread* @date 2024-10-08 15:08*/
@RestController
@RequestMapping("/practice")
public class PracticeController {// 路径参数@GetMapping("/path/{username}")public ResultData<String> welcomeWithPathVariable(@PathVariable String username) {return ResultData.success(username);}// 查询参数@GetMapping("/query")public ResultData<User> welcomeWithQueryParameter(User user) {return ResultData.success(user);}// 请求体@PostMapping("/body")public ResultData<User> welcomeWithRequestBody(@RequestBody User user) {return ResultData.success(user);}// 请求头@GetMapping("/header")public ResultData<String> welcomeWithHeader(@RequestHeader("username") String username) {return ResultData.success(username);}
}
@Data
class User {private String username;private String password;private String email;
}

python版测试代码
