环境搭建

C:\Windows\System32\drivers\etc\hosts

192.168.56.10 gulimall.com
192.168.56.10 search.gulimall.com
192.168.56.10 item.gulimall.com
192.168.56.10 auth.gulimall.com

Nginx配置：（记得使用Nginx动静分离）

# ...

http {
    # ...

    upstream gulimall {
       server 192.168.193.107:88;
    }

    include /etc/nginx/conf.d/*.conf;
}

网关：

        - id: gulimall_auth_route
          uri: lb://gulimall-auth
          predicates:
            - Host=auth.gulimall.com

gulimall-auth：

@Controller
public class LoginController {
    @GetMapping("/login.html")
    public String loginPage() {
        return "login";
    }

    @GetMapping("/reg.html")
    public String regPage() {
        return "reg";
    }
}

或者：

@Configuration
public class GulimallWebConfig implements WebMvcConfigurer {
    /**
     * 视图映射
     */
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {

        /**
         *     @GetMapping("/login.html")
         *     public String loginPage(){
         *          //空方法
         *         return "login";
         *     }
         */
        //只是get请求能映射
        registry.addViewController("/login.html").setViewName("login");
        registry.addViewController("/reg.html").setViewName("reg");
    }
}

验证码倒计时

前端：

    $(function () {
        $("#sendCode").click(function () {
            //2、倒计时
            if ($(this).hasClass("disabled")) {
                //正在倒计时。
            } else {
                //1、给指定手机号发送验证码
                // $.get("/sms/sendEmail?email=" + $("#phoneNum").val(), function (data) {
                $.get("/sms/sendcode?phone=" + $("#phoneNum").val(), function (data) {
                    if (data.code != 0) {
                        alert(data.msg);
                    }
                });
                timeoutChangeStyle();
            }
        });
    })

    var num = 60;

    function timeoutChangeStyle() {
        $("#sendCode").attr("class", "disabled");
        if (num == 0) {
            $("#sendCode").text("发送验证码");
            num = 60;
            $("#sendCode").attr("class", "");
        } else {
            var str = num + "s 后再次发送";
            $("#sendCode").text(str);
            setTimeout("timeoutChangeStyle()", 1000);
        }
        num--;
    }

短信服务

购买短信套餐后，扫码激活，然后绑定测试手机号码：

然后点击：调用API发送短信 按钮 （使用【专用】测试签名/模板）

然后 发起调用 ，复制相关信息即可

增加权限授予RAM子账号SMS和MPush的权限。

验证码

短信形式：

    @GetMapping("/sms/sendcode")
    public R sendCode(@RequestParam("phone") String phone) {
//        Redis缓存验证码：存起来方便下次校验 以及 可以给验证码设置有效期

        String code = getRandomCode().toString();

//        防止同一个手机号在60s内再次发送验证码
        String key = AuthServerConstant.SMS_CODE_CACHE_PREFIX + phone;

        String oldCode = stringRedisTemplate.opsForValue().get(key);
        if (!StringUtils.isEmpty(oldCode)) {
            long l = Long.parseLong(oldCode.split("_")[1]);
            if (System.currentTimeMillis() - l < 60000) { // 如果时间间隔小于60s
                return R.error(BizCodeEnume.SMS_MULTI_EXCEPTION);
            }
        }

//        R r = thirdPartyFeignService.sendSms(phone, code);
//        if (r.getCode() == BizCodeEnume.SUCCESS.getCode()) {
//            code = code + "_" + System.currentTimeMillis();
//            stringRedisTemplate.opsForValue().set(key, code, 5, TimeUnit.MINUTES); //过期时间5分钟
//        }
//        return r;

        CompletableFuture.runAsync(() -> thirdPartyFeignService.sendSms(phone, code), threadPool);
        CompletableFuture.runAsync(() -> {

        }, threadPool);
        return R.ok();
    }

生成验证码（随机四位数）：

    private Integer getRandomCode() {
        //4位数字验证码：想要[1000,9999]，也就是[1000,10000)

        // Math.random() -> [0, 1)  // (int) Math.random()永远为0
        // Math.random() * (end - begin) -> [0, end - begin)
        // begin + Math.random() * (end - begin) -> [begin, end)
        int code = (int) (1000 + Math.random() * (10000 - 1000));
        return code;
    }

邮件形式：

    @GetMapping("/sms/sendEmail")
    public R sendEmailCode(@RequestParam("email") String email) throws MessagingException {
        String code = UUID.randomUUID().toString().substring(0, 5);
        String key = AuthServerConstant.EMAIL_CODE_CACHE_PREFIX + email;

        String oldCode = stringRedisTemplate.opsForValue().get(key);
        if (!StringUtils.isEmpty(oldCode)) { // 说明5分钟内已经给该邮箱发送过验证码了
            long l = Long.parseLong(oldCode.split("_")[1]);
            if (System.currentTimeMillis() - l < 60000) { // 如果时间间隔小于60s
                return R.error(BizCodeEnume.SMS_MULTI_EXCEPTION);
            }
        }

        CompletableFuture.runAsync(() -> {
            // 给Redis放置验证码
            String realSaveCode = code + "_" + System.currentTimeMillis();
            stringRedisTemplate.opsForValue().set(key, realSaveCode, 5, TimeUnit.MINUTES); //过期时间5分钟
        }, threadPool);

        CompletableFuture.runAsync(() -> {
            // 发送邮件
            try {
                EmailTo emailTo = new EmailTo();
                emailTo.setReceiveMail(email);
                emailTo.setContent("验证码：" + code + "------有效期5分钟！");
                emailTo.setSubject("欢迎注册！");
                thirdPartyFeignService.sendEmail(emailTo);
            } catch (MessagingException e) {
                e.printStackTrace();
            }
        }, threadPool);

        return R.ok();
    }

MD5

MD5：Message Digest algorithm 5，信息摘要算法

• 压缩性：任意长度的数据，算出的MD5值长度都是固定的。
• 容易计算：从原数据计算出MD5值很容易。
• 抗修改性：对原数据进行任何改动，哪怕只修改1个字节，所得到的MD5值都有很大区别。
• 强抗碰撞：想找到两个不同的数据，使它们具有相同的MD5值，是非常困难的。
• 不可逆（即使知道加密算法，也不能反推出明文密码）: MD5是一种信息摘要算法，会损 失元数据，所以不可逆出原数据是什么

但是，由于MD5的抗修改性和强抗碰撞（一个字符串的MD5值永远是那个值），发明了彩虹表（暴力 破解）。所以，MD5不能直接进行密码的加密存储

加盐：

• 通过生成随机数与MD5生成字符串进行组合

• 数据库同时存储MD5值与salt值。验证正确性时使用salt进行MD5即可

  百度网盘的秒传：在上传文件之前，计算出该文件的MD5值，看有没有人之前上传过，也就是去匹配百度网盘的数据库中有没有相同的 MD5 值， 如果有一样的就不用传了

@RunWith(SpringRunner.class)
@SpringBootTest
public class GulimallAuthApplicationTests {
    @Test
    public void contextLoads() {
        //MD5是不可逆的，但是利用它的抗修改性（一个字符串的MD5值永远是那个值），发明了彩虹表（暴力破解）。
        //所以，MD5不能直接进行密码的加密存储;
//        String s = DigestUtils.md5Hex("123456");

        //盐值加密；随机值 加盐 ：$1$ + 8位字符
//        只要是同一个材料，做出来的饭是一样的，如果给饭里随机撒点"盐"，那么，饭的口味就不一样了
        //"123456"+System.currentTimeMillis();

        //想要再次验证密码咋办？： 将密码再进行盐值（去数据库查当时保存的随机盐）加密一次，然后再去匹配密码是否正确
//        String s1 = Md5Crypt.md5Crypt("123456".getBytes()); //随机盐
//        String s1 = Md5Crypt.md5Crypt("123456".getBytes(),"$1$qqqqqqqq"); //指定盐
//        System.out.println(s1);

//        给数据库加字段有点麻烦，Spring有好用的工具：
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
//        String encode = passwordEncoder.encode("123456");
//        $2a$10$coLmFyeppkTPTfD0RJgqL.nx33s0wvUmj.shqEM/6hvwOO4TWiGmy
//        $2a$10$4IP4F/2iFO2gbSvQKyJzGuI3RhU5Qdtr519KsyoXGAy.b7WT4P1RW
//        $2a$10$0hEI3vMkTbTqK76990MGu.s9QKrkjDSpgyhfzR4zsy07oKB9Jw.PS

//        System.out.println(encode);
//        boolean matches = passwordEncoder.matches("123456", "$2a$10$0hEI3vMkTbTqK76990MGu.s9QKrkjDSpgyhfzR4zsy07oKB9Jw.PS");
        boolean matches = passwordEncoder.matches("lpruoyu123", "$2a$10$m7TmOQAin5Tj6QzV1TT0ceW6iLypdN8LHkYP16DUEngJUfYNgWVEm");
        System.out.println(matches);
    }
