✅P219_商城业务-认证服务-账号密码登录完成

编写Vo

UserLoginVo

cfmall-auth-server/src/main/java/com/gyz/cfmall/vo/UserLoginVo.java

package com.gyz.cfmall.vo;

import lombok.Data;

@Data
public class UserLoginVo {
    /**
     * 登录账户。用户名或手机号
     */
    private String loginacct;
    /**
     * 密码
     */
    private String password;
}

MemberUserLoginVo

cfmall-member/src/main/java/com/gyz/cfmall/member/vo/MemberUserLoginVo.java

package com.gyz.cfmall.member.vo;

import lombok.Data;

@Data
public class MemberUserLoginVo {

    private String loginacct;

    private String password;
}

数据绑定

cfmall-auth-server/src/main/resources/templates/login.html

<form action="/login" method="post">
    <!-- 错误信息提示-->
	<div style="color: red"
		 th:text="${errors != null ? (#maps.containsKey(errors, 'msg') ? errors.msg : '') : ''}"></div>
	<ul>
		<li class="top_1">
			<img src="/static/login/JD_img/user_03.png" class="err_img1"/>
             <!-- loginacct要和vo定义的一致-->
			<input name="loginacct" type="text" placeholder=" 邮箱/用户名/已验证手机" class="user"/>
		</li>
		<li>
			<img src="/static/login/JD_img/user_06.png" class="err_img2"/>
			<input name="password" type="password" placeholder=" 密码" class="password"/>
		</li>
		<li class="bri">
			<a href="/static/login/">忘记密码</a>
		</li>
		<li class="ent">
             <!-- 此处注意把原先的 calss="a" 去掉，要不然会跳转到百度首页-->
			<button class="btn2" type="submit">登 &nbsp; &nbsp;录</a></button>
		</li>
	</ul>
</form>

登录接口

cfmall-auth-server/src/main/java/com/gyz/cfmall/controller/LoginController.java

注意：不能加@RequestBody注解，这里是页面提交表单数据，数据类型是map并非json

@PostMapping("/login")
public String login(UserLoginVo userLoginVo, RedirectAttributes attributes) {
    R r = memberFeignService.login(userLoginVo);
    if (r.getCode() == 0) {
        log.info("账号密码登录成功");
        return "redirect:http://cfmall.com";
    } else {
        Map<String, String> errors = new HashMap<>();
        errors.put("msg", r.getData("msg", new TypeReference<String>() {
        }));
        attributes.addFlashAttribute("errors", errors);
        return "redirect:http://auth.cfmall.com/login.html";
    }
}

Feign

cfmall-auth-server/src/main/java/com/gyz/cfmall/feign/MemberFeignService.java

 /**
  * 远程调用用户登录
  * @param userLoginVo
  * @return
  */
 @PostMapping(value = "/member/member/login")
 R login(@RequestBody UserLoginVo userLoginVo);

---

会员服务接口

cfmall-member/src/main/java/com/gyz/cfmall/member/controller/MemberController.java

    @PostMapping(value = "/login")
    public R login(@RequestBody MemberUserLoginVo userLoginVo) {
        MemberEntity memberEntity = memberService.login(userLoginVo);
        if (memberEntity != null) {
            return R.ok();
        } else {
            return R.error(BizCodeEnum.LOGINACCT_PASSWORD_EXCEPTION.getCode(), BizCodeEnum.LOGINACCT_PASSWORD_EXCEPTION.getMessage());
        }
    }

枚举类编写cfmall-common/src/main/java/com/gyz/common/exception/BizCodeEnum.java

LOGINACCT_PASSWORD_EXCEPTION(15003,"账号或密码错误"),

登录逻辑cfmall-member/src/main/java/com/gyz/cfmall/member/service/impl/MemberServiceImpl.java

	@Override
    public MemberEntity login(MemberUserLoginVo userLoginVo) {
        String loginacct = userLoginVo.getLoginacct();
        String password = userLoginVo.getPassword();

        MemberEntity memberEntity = this.baseMapper.selectOne(new QueryWrapper<MemberEntity>().eq("username", loginacct).or().eq("mobile", loginacct));
        if (memberEntity == null) {
            return null;
        } else {
            BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
            boolean matches = bCryptPasswordEncoder.matches(password, memberEntity.getPassword());
            if (matches) {
                return memberEntity;
            }
        }
        return null;
    }
