1、模擬get請求

package com.course.server;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyGetMethod {

    @RequestMapping(value = "/useSpringBoot/getcookies",method = RequestMethod.GET)
    public String getCookie(){
        return "這是我的返回結(jié)果";
    }
}

2、模擬get請求返回cookie

package com.course.server;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

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

@RestController
public class MyGetMethod {


    //模擬get請求
    @RequestMapping(value = "/useSpringBoot/get",method = RequestMethod.GET)
    public String get(){
        return "這是我的get請求的返回結(jié)果";
    }

    //模擬get請求返回cookie信息
    @RequestMapping(value = "/useSpringBoot/getcookies",method = RequestMethod.GET)
    public String getCookie(HttpServletResponse response){
        Cookie cookie=new Cookie("login","true");
        response.addCookie(cookie);
        return "這是我的get請求返回cookie的請求結(jié)果";
    }



}

3、模擬get請求攜帶cookie信息

package com.course.server;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
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.Objects;

@RestController
public class MyGetMethod {


    //模擬get請求
    @RequestMapping(value = "/useSpringBoot/get",method = RequestMethod.GET)
    public String get(){
        return "這是我的get請求的返回結(jié)果";
    }

    //模擬get請求返回cookie信息
    //HttpServletResponse類是一個存儲器，可以把cookie等信息加入到response中返回
    @RequestMapping(value = "/useSpringBoot/getResponseCookies",method = RequestMethod.GET)
    public String getResponseCookie(HttpServletResponse response){
        Cookie cookie=new Cookie("login","true");
        response.addCookie(cookie);
        return "這是我的get請求返回cookie的請求結(jié)果";
    }

    //模擬get請求攜帶cookie信息
    //HttpServletRequest類是一個存儲器，可以把cookie等信息加入到請求中去訪問get請求
    @RequestMapping(value = "/useSpringBoot/getwithCookies",method = RequestMethod.GET)
    public String getwithCookies(HttpServletRequest request){
        //從get請求攜帶的cookie中獲取cookie，并賦值給cookies數(shù)組
        Cookie[] cookies = request.getCookies();

        //判斷cookies數(shù)組是否為空，如果為空返回錯誤，不為空判斷cookies是不是獲取到的cookies
        if(Objects.isNull(cookies)){
            return "必須攜帶cookie信息";
        }
        //foreach循環(huán)cookies，對象類型是cookie類，利用cookie類的getName和getValue方法判斷cookies信息
        for(Cookie cookie : cookies){
            if(cookie.getName().equals("login") && cookie.getValue().equals("true")){
                return "這是一個攜帶cookie信息的get請求";
            }
        }
        return "cookies信息校驗(yàn)失敗";

    }



}

4、模擬get請求攜帶參數(shù)

package com.course.server;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
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.HashMap;
import java.util.Map;
import java.util.Objects;

@RestController
public class MyGetMethod {


    //模擬get請求
    @RequestMapping(value = "/useSpringBoot/get",method = RequestMethod.GET)
    public String get(){
        return "這是我的get請求的返回結(jié)果";
    }

    //模擬get請求返回cookie信息
    //HttpServletResponse類是一個存儲器，可以把cookie等信息加入到response中返回
    @RequestMapping(value = "/useSpringBoot/getResponseCookies",method = RequestMethod.GET)
    public String getResponseCookie(HttpServletResponse response){
        Cookie cookie=new Cookie("login","true");
        response.addCookie(cookie);
        return "這是我的get請求返回cookie的請求結(jié)果";
    }

    //模擬get請求攜帶cookie信息
    //HttpServletRequest類是一個存儲器，可以把cookie等信息加入到請求中去訪問get請求
    @RequestMapping(value = "/useSpringBoot/getwithCookies",method = RequestMethod.GET)
    public String getwithCookies(HttpServletRequest request){
        //從get請求攜帶的cookie中獲取cookie，并賦值給cookies數(shù)組
        Cookie[] cookies = request.getCookies();

        //判斷cookies數(shù)組是否為空，如果為空返回錯誤，不為空判斷cookies是不是獲取到的cookies
        if(Objects.isNull(cookies)){
            return "必須攜帶cookie信息";
        }
        //foreach循環(huán)cookies，對象類型是cookie類，利用cookie類的getName和getValue方法判斷cookies信息
        for(Cookie cookie : cookies){
            if(cookie.getName().equals("login") && cookie.getValue().equals("true")){
                return "這是一個攜帶cookie信息的get請求";
            }
        }
        return "cookies信息校驗(yàn)失敗";

    }
    //模擬get請求攜帶參數(shù)
    @RequestMapping(value = "/useSpringBoot/getwithParam",method = RequestMethod.GET)
    public Map<String,String> getwithParam(@RequestParam("goodsid") String goodsid,
                                           @RequestParam("goodsdes") String goodsdes){

        Map<String,String> map=new HashMap<>();
        map.put("goodsid",goodsid);
        map.put("goodsdes",goodsdes);

        return map;

    }
}

5、模擬get請求攜帶參數(shù)二,使用@PathVariable注解獲取參數(shù)值

package com.course.server;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;
import java.util.Objects;

@RestController
public class MyGetMethod {


    //模擬get請求
    @RequestMapping(value = "/useSpringBoot/get",method = RequestMethod.GET)
    public String get(){
        return "這是我的get請求的返回結(jié)果";
    }

    //模擬get請求返回cookie信息
    //HttpServletResponse類是一個存儲器，可以把cookie等信息加入到response中返回
    @RequestMapping(value = "/useSpringBoot/getResponseCookies",method = RequestMethod.GET)
    public String getResponseCookie(HttpServletResponse response){
        Cookie cookie=new Cookie("login","true");
        response.addCookie(cookie);
        return "這是我的get請求返回cookie的請求結(jié)果";
    }

    //模擬get請求攜帶cookie信息
    //HttpServletRequest類是一個存儲器，可以把cookie等信息加入到請求中去訪問get請求
    @RequestMapping(value = "/useSpringBoot/getwithCookies",method = RequestMethod.GET)
    public String getwithCookies(HttpServletRequest request){
        //從get請求攜帶的cookie中獲取cookie，并賦值給cookies數(shù)組
        Cookie[] cookies = request.getCookies();

        //判斷cookies數(shù)組是否為空，如果為空返回錯誤，不為空判斷cookies是不是獲取到的cookies
        if(Objects.isNull(cookies)){
            return "必須攜帶cookie信息";
        }
        //foreach循環(huán)cookies，對象類型是cookie類，利用cookie類的getName和getValue方法判斷cookies信息
        for(Cookie cookie : cookies){
            if(cookie.getName().equals("login") && cookie.getValue().equals("true")){
                return "這是一個攜帶cookie信息的get請求";
            }
        }
        return "cookies信息校驗(yàn)失敗";

    }
    //模擬get請求攜帶參數(shù)
    @RequestMapping(value = "/useSpringBoot/getwithParam",method = RequestMethod.GET)
    public Map<String,String> getwithParam(@RequestParam("goodsid") String goodsid,
                                           @RequestParam("goodsdes") String goodsdes){

        Map<String,String> map=new HashMap<>();
        map.put("goodsid",goodsid);
        map.put("goodsdes",goodsdes);

        return map;

    }
    //模擬get請求攜帶參數(shù) @PathVariable
    @RequestMapping(value = "/useSpringBoot/getwithParamtwo/{goodsid}/{goodsdes}",method = RequestMethod.GET)
    public Map<String,String> getwithParamtwo(@PathVariable("goodsid") String goodsid,
                                               @PathVariable("goodsdes") String goodsdes){
        Map<String,String> map=new HashMap<>();
        map.put("goodsid",goodsid);
        map.put("goodsdes",goodsdes);
        return map;
    }
}

6、模擬post請求返回cookies信息

package com.course.server;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

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

@RestController
@Api(value = "/",description = "post請求接口")
public class MyPostMethod {

    //定義cookie全局變量，供需要攜帶cookie的接口使用
    Cookie cookie;

    //定義一個login的post方法，然后返回cookie信息
    @RequestMapping(value = "/useSpringBoot/postlogin",method = RequestMethod.POST)
    @ApiOperation(value = "登錄接口返回cookie信息",httpMethod = "POST")
    public String Login(HttpServletResponse response,
                        @RequestParam("name") String name,
                        @RequestParam("password") String password){
        
        
        //如果用戶名和密碼成功，就添加cookie信息，然后添加到response中，然后成功信息
        if(name.equals("qinzhenxia") && password.equals("123456")){
            cookie=new Cookie("token","1234567890");
            response.addCookie(cookie);
            return "返回cookie，登錄成功";
        }
        return "登錄失敗";


    }


}

7、模擬post請求攜帶cookies信息
以下代碼中g(shù)etusers方法就是攜帶cookies信息的post請求

package com.course.server;

import com.course.Bean.User;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
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 = "post請求接口")
public class MyPostMethod {

    //定義cookie全局變量，供需要攜帶cookie的接口使用
    Cookie cookie;

    //定義一個login的post方法，然后返回cookie信息
    @RequestMapping(value = "/useSpringBoot/postlogin", method = RequestMethod.POST)
    @ApiOperation(value = "登錄接口返回cookie信息", httpMethod = "POST")
    public String Login(HttpServletResponse response,
                        @RequestParam("name") String name,
                        @RequestParam("password") String password) {


        //如果用戶名和密碼成功，就添加cookie信息，然后添加到response中，然后成功信息
        if (name.equals("qinzhenxia") && password.equals("123456")) {
            cookie = new Cookie("token", "1234567890");
            //在response中添加cookie并返回cookie
            response.addCookie(cookie);
            return "返回cookie，登錄成功";
        }
        return "success";


    }

    //創(chuàng)建users對象，getusers接口會用到該對象創(chuàng)建用戶登錄信息。
    User users;

    //用postman請求Login接口，會自動存儲cookie，再請求getusers接口時會自動把cookie帶上，所以請求時不需要再單獨(dú)處理cookie
    //攜帶cookie信息請求接口，同時返回用戶列表的post接口
    @RequestMapping(value = "/useSpringBoot/postResponseUsers", method = RequestMethod.POST)
    @ApiOperation(value = "攜帶cookie信息請求接口，同時返回用戶列表的post接口", httpMethod = "POST")
    public User getusers(HttpServletRequest request, @RequestBody User user) {


        //上一個接口返回的cookie，本接口去獲取
        Cookie[] cookie=request.getCookies();
        for(Cookie cookie1 : cookie){
            if(cookie1.getName().equals("token") && cookie1.getValue().equals("1234567890") &&
            user.getLoginname().equals("qinzhenxia") && user.getPassword().equals("123456")){
                //接口的請求參數(shù)是Loginname和Password
                //接口的返回參數(shù)是Loginname、Password、Name、Age、Sex
                //請求和返回的格式都是json
                //給user類中的屬性賦值并返回
                users=new User();
                users.setLoginname("qinzhenxia");
                users.setPassword("123456");
                users.setName("sunqihua");
                users.setAge(28);
                users.setSex("男");
                return users;
            }
        }
        return null;

    }
}
