企业级用户登录流程及代码实现

注意：有哪里看不懂的或者是想看完整的注册、验证、登录、第三方登录等流程和代码，请查看本专栏文章。

1、编写认证服务调用会员服务的service.

package com.atguigu.***.auth.feign;

import com.atguigu.common.utils.R;
import com.atguigu.***.auth.vo.UserLoginVo;
import com.atguigu.***.auth.vo.UserRegistVo;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;

/**
 * @author guanghaocheng
 * @version 1.0
 * 翼以尘雾之微补益山海,荧烛末光增辉日月
 * @date 2021/7/8 19:53
 */
@FeignClient("***-member")
public interface MemberFeignService {

    @PostMapping("/member/member/regist")
    public R regist(@RequestBody UserRegistVo vo);

    @PostMapping("member/member/login")
    public R login(@RequestBody UserLoginVo vo);
}

2、认证服务登录的接口。

@PostMapping("/login")
    public String login(UserLoginVo vo,RedirectAttributes redirectAttributes){
        //远程登录
        R r = memberFeignService.login(vo);
        if(r.getCode() == 0){
            //登录成功
            return "redirect:http://***.com";
        }else{
            Map<String,String> errors = new HashMap<>();
            errors.put("msg",r.getData("msg",new TypeReference<String>(){}));
            redirectAttributes.addFlashAttribute("errors",errors);
            return "redirect:http://auth.***.com/login.html";
        }
    }

3、会员模块的登录接口。

@PostMapping("/login")
    public R login(@RequestBody MemberLoginVo vo){
        MemberEntity entity = memberService.login(vo);
        if(entity != null){
            //TODO 1、登录成功的获取数据及处理
            return R.ok();
        }else{
            return R.error(BizCodeEnume.LOGINACCT_PASSWORD_INVAILD_EXCEPTION.getCode(),BizCodeEnume.LOGINACCT_PASSWORD_INVAILD_EXCEPTION.getMsg());
        }
    }

4、会员模块的登录service实现。

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

        //1、去数据库查询 select * from ums_member where username = ? or mobile = ? or email = ?
        MemberDao baseMapper = this.baseMapper;
        MemberEntity entity = baseMapper.selectOne(new QueryWrapper<MemberEntity>().eq("username", loginacct).or().eq("mobile", loginacct).or().eq("email", loginacct));
        if(entity == null){
            //根据用户名没查到信息，则直接登录失败
            return null;
        }else{
            //根据用户名查到信息了，进行密码比对
            String passwordDB = entity.getPassword();//获取数据库存的密码
            BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
            boolean matches = bCryptPasswordEncoder.matches(password, passwordDB);
            if(matches){
                //登录成功
                return entity;
            }else{
                //登录失败
                return null;
            }
        }
//        return null;
    }
