当前登录的用户点击了”赞“,就要保存当前行为数据
可以取消点赞

public ResponseResult likesBehavior(LikesBehaviorDto dto) {// 1. 检查参数if(dto == null || dto.getArticleId() == null || checkParam(dto)){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID);}// 2. 是否登录ApUser user = AppThreadLocalUtil.getUser();if(user == null){return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);}// 3. 点赞, 保存数据if(dto.getOperation() == 0){// 点赞Object obj = cacheService.hGet(BehaviorConstants.LIKE_BEHAVIOR + dto.getArticleId().toString(), user.getId().toString());if(obj != null){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID, "已点赞");}// 保存当前keylog.info("保存当前key:{} ,{}, {}", BehaviorConstants.LIKE_BEHAVIOR+dto.getArticleId(), user.getId(), dto);cacheService.hPut(BehaviorConstants.LIKE_BEHAVIOR + dto.getArticleId().toString(), user.getId().toString(), JSON.toJSONString(dto));}else{// 取消点赞// 删除当前keylog.info("删除当前key:{}, {}", BehaviorConstants.LIKE_BEHAVIOR+dto.getArticleId(), user.getId());cacheService.hDelete(BehaviorConstants.LIKE_BEHAVIOR + dto.getArticleId().toString(), user.getId().toString());}return ResponseResult.okResult(AppHttpCodeEnum.SUCCESS);
}private boolean checkParam(LikesBehaviorDto dto) {if(dto.getType() > 2 || dto.getType() < 0 || dto.getOperation() > 1 || dto.getOperation() < 0){return true;}return false;
}

阅读

当用户查看了某一篇文章，需要记录当前用户查看的次数

public ResponseResult readBehavior(ReadBehaviorDto dto) {// 1. 检查次数if(dto == null || dto.getArticleId() == null || dto.getCount() == null){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID);}// 2. 是否登录ApUser user = AppThreadLocalUtil.getUser();if(user == null){return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);}// 3. 阅读, 保存数据// 3.1 更新阅读次数String readBehaviorJson = (String) cacheService.hGet(BehaviorConstants.READ_BEHAVIOR + dto.getArticleId().toString(), user.getId().toString());if(StringUtils.isNotBlank(readBehaviorJson)){ReadBehaviorDto readBehaviorDto = JSON.parseObject(readBehaviorJson, ReadBehaviorDto.class);dto.setCount(readBehaviorDto.getCount()+dto.getCount());}// 3.2 保存数据// 保存当前keylog.info("保存当前key:{} {} {}", BehaviorConstants.READ_BEHAVIOR+dto.getArticleId(), user.getId(), dto);cacheService.hPut(BehaviorConstants.READ_BEHAVIOR+dto.getArticleId().toString(), user.getId().toString(), JSON.toJSONString(dto));return ResponseResult.okResult(AppHttpCodeEnum.SUCCESS);
}

不喜欢

用户点击了不喜欢, 就不再给当前用户推荐这一类型的文章信息

public ResponseResult unLikesBehavior(UnLikesBehaviorDto dto) {// 1. 检查次数if(dto == null || dto.getArticleId() == null || dto.getType() > 1 || dto.getType() < 0){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID);}// 2. 是否登录ApUser user = AppThreadLocalUtil.getUser();if(user == null){return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);}// 3. 不喜欢文章, 保存数据if(dto.getType() == 0){// 不喜欢Object o = cacheService.hGet(BehaviorConstants.UN_LIKE_BEHAVIOR + dto.getArticleId().toString(), user.getId().toString());if(o != null){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID, "已经不喜欢");}log.info("保存当前key:{} ,{}, {}", BehaviorConstants.UN_LIKE_BEHAVIOR+dto.getArticleId(), user.getId(), dto);cacheService.hPut(BehaviorConstants.UN_LIKE_BEHAVIOR + dto.getArticleId().toString(), user.getId().toString(), JSON.toJSONString(dto));}else{// 取消不喜欢log.info("删除当前key:{}, {}", BehaviorConstants.UN_LIKE_BEHAVIOR+dto.getArticleId(), user.getId());cacheService.hDelete(BehaviorConstants.UN_LIKE_BEHAVIOR + dto.getArticleId().toString(), user.getId().toString());}return ResponseResult.okResult(AppHttpCodeEnum.SUCCESS);
}

关注

当前登录后的用户可以关注作者，也可以取消关注作者
从用户的角度出发：一个用户可以关注其他多个作者 —— 我的关注
从作者的角度出发：一个用户（同是作者）也可以拥有很多个粉丝 —— 我的粉丝

public ResponseResult userFollow(UserRelationDto dto) {// 1. 检查参数if(dto == null || checkParam(dto)){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID);}// 2. 是否登录ApUser user = AppThreadLocalUtil.getUser();if(user == null){return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);}// 3. 关注, 保存数据if(dto.getOperation() == 0){// 关注// 将作者写入我的关注中cacheService.zAdd(BehaviorConstants.APUSER_FOLLOW_RELATION+user.getId(), dto.getAuthorId().toString(), System.currentTimeMillis());// 将我写入作者的粉丝中cacheService.zAdd(BehaviorConstants.APUSER_FANS_RELATION+dto.getAuthorId(), user.getId().toString(), System.currentTimeMillis());}else{// 取消关注cacheService.zRemove(BehaviorConstants.APUSER_FOLLOW_RELATION+user.getId(), dto.getAuthorId().toString());cacheService.zRemove(BehaviorConstants.APUSER_FANS_RELATION+dto.getAuthorId(), user.getId().toString());}return ResponseResult.okResult(AppHttpCodeEnum.SUCCESS);
}private boolean checkParam(UserRelationDto dto) {if(dto.getArticleId() == null || dto.getAuthorId() == null){return true;}if(dto.getOperation() > 1 || dto.getOperation() < 0){return true;}return false;
}

记录当前登录人收藏的文章

public ResponseResult collectionBehavior(CollectionBehaviorDto dto) {// 1. 检查参数if(dto == null || checkParam(dto)){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID);}// 2. 是否登录ApUser user = AppThreadLocalUtil.getUser();if(user == null){return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);}// 3. 文章收藏, 数据保存if(dto.getOperation() == 0){// 收藏// 判断是否已经收藏String collectionJson = (String) cacheService.hGet(BehaviorConstants.COLLECTION_BEHAVIOR + dto.getEntryId(), user.getId().toString());if(StringUtils.isNotBlank(collectionJson)){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID, "已收藏");}log.info("文章收藏，保存key:{},{},{}",BehaviorConstants.COLLECTION_BEHAVIOR + user.getId(),dto.getEntryId().toString(), JSON.toJSONString(dto));cacheService.hPut(BehaviorConstants.COLLECTION_BEHAVIOR + user.getId(),dto.getEntryId().toString(), JSON.toJSONString(dto));}else{// 取消收藏log.info("文章收藏，删除key:{},{},{}",BehaviorConstants.COLLECTION_BEHAVIOR + user.getId(),dto.getEntryId().toString());cacheService.hDelete(BehaviorConstants.COLLECTION_BEHAVIOR + user.getId(),dto.getEntryId().toString());}return ResponseResult.okResult(AppHttpCodeEnum.SUCCESS);
}

文章详情-行为数据回显

展示文章的关系，app端用户必须登录，判断当前用户是否已经关注该文章的作者、是否收藏了此文章、是否点赞了文章、是否不喜欢该文章等

public ResponseResult loadArticleBehavior(ArticleInfoDto dto) {// 1. 检查数据if(dto == null || dto.getArticleId() == null || dto.getAuthorId() == null){return ResponseResult.errorResult(AppHttpCodeEnum.PARAM_INVALID);}// 2. 是否登录ApUser user = AppThreadLocalUtil.getUser();if(user == null){return ResponseResult.errorResult(AppHttpCodeEnum.NEED_LOGIN);}// 3. 回显数据Map<String, Boolean> map = new HashMap<>();Boolean islike = false, isunlike = false, iscollection = false, isfollow = false;// 3.1 是否点赞String likeJson = (String) cacheService.hGet(BehaviorConstants.LIKE_BEHAVIOR + dto.getArticleId(), user.getId().toString());if(likeJson != null){islike = true;}// 3.2 是否不喜欢String unLikeJson = (String) cacheService.hGet(BehaviorConstants.UN_LIKE_BEHAVIOR + dto.getArticleId(), user.getId().toString());if(unLikeJson != null){isunlike = true;}// 3.3 是否收藏String collectiontJson = (String) cacheService.hGet(BehaviorConstants.COLLECTION_BEHAVIOR + user.getId(), dto.getArticleId().toString());if(collectiontJson != null){iscollection = true;}// 3.4 是否关注Double score = cacheService.zScore(BehaviorConstants.APUSER_FOLLOW_RELATION + user.getId(), dto.getAuthorId().toString());if(score != null){isfollow = true;}map.put("islike", islike);map.put("isunlike", isunlike);map.put("iscollection", iscollection);map.put("isfollow", isfollow);return ResponseResult.okResult(map);
