目录一、获取当前用户信息1.1 controller1.2 service二、退出登录2.1 controller2.2 service一、获取当前用户信息流程分析前端携带着token向后端发起请求(放在请求头中)通过token进行身份认证。身份认证失败直接结束。身份认证成功接着执行第三步。解析token从token中获取用户唯一标识通过用户的唯一标识从redis获取当前用户的信息redis 获取到的用户信息返回给前端。如果获取失败失败的原因也应该返给前端。1.1 controllercom.yj.system.controller.SysUserController类下添加方法/** * 获取当前用户信息 * param token * return */GetMapping(/info)publicRLoginUserVOinfo(RequestHeader(HttpConstants.AUTHENTICATION)Stringtoken){returnsysUserService.info(token);}packagecom.yj.common.core.domain.vo;importlombok.Getter;importlombok.Setter;GetterSetterpublicclassLoginUserVO{privateStringnickName;}1.2 servicecom.yj.system.service.ISysUserService接口RLoginUserVOinfo(Stringtoken);oj-modules/oj-system/src/main/java/com/yj/system/service/impl/SysUserServiceImpl.java实现OverridepublicRLoginUserVOinfo(Stringtoken){//添加前缀if(StrUtil.isNotEmpty(token)token.startsWith(HttpConstants.PREFIX)){tokentoken.replaceFirst(HttpConstants.PREFIX,StrUtil.EMPTY);}//在redis先行获取LoginUserloginUsertokenService.getLoginUser(token,jwtSecret);if(nullloginUser){returnR.fail();}LoginUserVOloginUserVOnewLoginUserVO();loginUserVO.setNickName(loginUser.getNickName());returnR.success(loginUserVO);}oj-common/oj-common-security/src/main/java/com/yj/common/security/service/TokenService.javaredis线管添加获取缓存中的用户信息publicLoginUsergetLoginUser(Stringtoken,StringjwtSecret){StringuserKeygetUserKey(token,jwtSecret);if(nulluserKey)returnnull;returnredisService.getCacheObject(getTokenKey(userKey),LoginUser.class);}二、退出登录用户点击退出登录并且确认退出将退出登录请求(携带token)发送至后端。(1.后端得先验证用户是处于登录状态并且需要验证用户是管理员用户后端处理退出登录的逻辑(将redis中的用户数据删除让token认证失败)返回结果如果失败流程结束继续保持登录状态停留在当前页面。如果成功执行后续流程。前端清除存储的token返回登录页面2.1 controllercom.yj.system.controller.SysUserController类下添加方法/** * 退出登录 * param token * return */DeleteMapping(/logout)publicRVoidlogout(RequestHeader(HttpConstants.AUTHENTICATION)Stringtoken){returntoR(sysUserService.logout(token));}2.2 servicecom.yj.system.service.ISysUserService接口booleanlogout(Stringtoken);oj-modules/oj-system/src/main/java/com/yj/system/service/impl/SysUserServiceImpl.java实现Overridepublicbooleanlogout(Stringtoken){if(StrUtil.isNotEmpty(token)token.startsWith(HttpConstants.PREFIX)){tokentoken.replaceFirst(HttpConstants.PREFIX,StrUtil.EMPTY);}returntokenService.deleteLoginUser(token,jwtSecret);}oj-common/oj-common-security/src/main/java/com/yj/common/security/service/TokenService.javaredis中删除缓存中的用户信息publicbooleandeleteLoginUser(Stringtoken,StringjwtSecret){StringuserKeygetUserKey(token,jwtSecret);if(nulluserKey)returnfalse;returnredisService.deleteObject((getTokenKey(userKey)));}
