Springboot+post請求接口

本文是Springboot+post請求接口的生成，包含了帶cookie 和參數發送post請求。新增lombok框架，lombok的使用可以不用在類中添加成員變量的get/set方法。框架自帶了相關方法。如不需要再添加以下內容

   public String getUsename() {
        return usename;
    }

    public void setUsename(String usename) {
        this.usename = usename;
    }

 

 

 

 

 

 

 

 

<dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.14</version>
        </dependency>
    </dependencies>

 

java post請求代碼如下

package com.course.server;

import com.course.bean.User;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import jdk.internal.org.objectweb.asm.tree.analysis.Value;
import org.springframework.web.bind.annotation.*;

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

@RestController
@Api(value = "/", description = "這是我全部的post請")
@RequestMapping("/V1")
public class MyPostMethod {
    //這個變量用來裝我們的cookies信息
    private static Cookie cookie;
    //模擬場景：用戶登錄成功獲取到cookies,然后訪問其他接口獲取到列表

    /**
     * 模擬用戶登錄場景
     * @param response
     * @param userName
     * @param password
     * @return
     */
    @RequestMapping(value = "/login", method = RequestMethod.POST)
    @ApiOperation(value = "登錄接口，成功登錄后獲取cookies", httpMethod = "POST")
    public String login(HttpServletResponse response,
                        @RequestParam(value = "username", required = true) String userName,
                        // @RequestParam(value = "username1",required = true)String userName,
                        // @RequestParam傳遞的參數格式是param格式
                        // username1和前端傳遞的參數一致，
                        //String userName,可以和前端不一致
                        @RequestParam(value = "password", required = true) String password) {
        if (userName.equals("zhangshan") && password.equals("111111")) {
            cookie = new Cookie("login", "true");
            response.addCookie(cookie);
            return "恭喜你登錄成功";
        } else
            return "用戶名或密碼錯誤";

    }

    /**
     * 攜帶cookie的指定用戶獲取用戶列表信息  
     * @param request
     * @param user
     * @return
     */
    @RequestMapping(value = "/getUserList", method = RequestMethod.POST)
    @ApiOperation(value = "獲取用戶列表", httpMethod = "POST")
    public String getUserList(HttpServletRequest request, @RequestBody User user) {
//必須寫上HttpServletRequest reques，或者cookie 值無法帶上cookie值  @RequestBody需要傳遞的參數格式應該是json格式

        //獲取cookies
        User user1 = new User();
        Cookie[] cookies = request.getCookies();//獲取cookie值
        for (Cookie cookie : cookies) {
            if (cookie.getName() .equals("login" )&& cookie.getValue().equals("true") &&
                    user.getName().equals("zhangshan") && user.getPassword().equals("111111")) {

                user1.setUsename("lisi");
                user1.setAge("18");

                return user1.toString();
            }

        }

        return "參數不合法";

    }

}

User類（用戶列表中返回的信息）

package com.course.bean;
import lombok.Data;
@Data
public class User {
    private String usename;
    private  String password;
    private String name;
    private  String age;
    //以下內容 因為引入了lombox框架而不需要再添加成員變量的get/set方法。
//    public String getUsename() {
//        return usename;
//    }
//
//    public void setUsename(String usename) {
//        this.usename = usename;
//    }
//
//    public String getPassword() {
//        return password;
//    }
//
//    public void setPassword(String password) {
//        this.password = password;
//    }
//
//    public String getName() {
//        return name;
//    }
//
//    public void setName(String name) {
//        this.name = name;
//    }
//
//    public String getAge() {
//        return age;
//    }
//
//    public void setAge(String age) {
//        this.age = age;
//    }
}
