前言

ok,又到了水文时间了,那么今天带来的是这个WhiteHole的最新的开发进度,也就是实现了我们的博文的基本功能。那么之后比较重大的功能就是我们的消息系统+流量统计(文章,问答之类的数据信息)其他的什么社区,社区管理什么的和我们先前的业务是类似的。所以的话这里就不想复述了,因为意义不大,那部分的话基本上技术没什么难的就是基本的CURD+调用微服务。实话实说,这部分的开发对我来说其实就是繁琐,其实很简单,当然要考虑的东西不少。然后的话还有咱们的后台管理系统,这部分用户端做的差不多了,这个后台的其实也快,无法也是CURD+一些高权限的操作。现阶段的代码还是一个初级阶段,后面把组件上齐了,咱们还会在修改说明的。

那么这次的话也是我们尽可能完整一点。
不过的话也是有部分内容重复的,所以请先阅读这篇文章:

其实这里的实现逻辑和先前的那个很像,区别就是说,但是先前的话也是没有说完整,那么现在的话我们说仔细一点,完整的前端代码+后端的主要业务代码。

博文列表

首先来说的是我们的一个博文的列表。

先说一下我们的这个博文的这个数据表:

我们这边是将内容和我们的blog分开的。因为我们这边要实现很多的操作,比如文章的fork,合并修等等。

前端

我们先来看到前端的完整的代码,这里的话我就直接给出我这个显示的列表的代码。这里的前端的所有的代码都是没有封装的,好处是方便修改,方便理解。坏处是,不方便调用,但是不好维护,所以的话,不去封装了,开发完再说,还有很多的辅助功能没做呢。

那么我们就来看看吧:

我们这边的话,为了防止客户端的数据丢失以及降低我们的服务端的压力,所以的话做一个缓存,当然我们服务端还是有哨兵的,双重限流嘛。

后端接口

之后的话,就是接口的实现,这个其实相当简单,查表就好了,当然我们这边 还要做一个缓存,这个缓存的话就是直接使用SpringCache来做的。
首先是我们的接口:

    @RequestMapping("/last")
    @Cacheable(value={"homePageBlog:lastHomePageList"},key = "#root.methodName")
    public R lastHomePageList() throws Exception {
        return blogHomePageService.lastBlogList();
    }

之后的话是我们的实现类:

   @Override
    public R lastBlogList() throws Exception {
        HashMap<String, Object> params = new HashMap<>();
        //组装请求博文列表所需要的数据,当访问的为内部接口时,所有的参数均为Map形式
        params.put("page","1");
        params.put("limit","10");
        params.put("accurate","single");
        //此时指定HoleNULL,那么这个key不参与查询,但是需要进行占位,不能为空
        params.put("table_name","HoleNULL");
        params.put("key","1");
        params.put("order","desc");
        params.put("status","1");
        params.put("level","1");
        PageUtils page = blogService.queryPage(params);
        return R.ok().put("page", page);
    }

这里的话我们重写了这个queryPage的方法来实现分页。

public class BlogServiceImpl extends ServiceImpl<BlogDao, BlogEntity> implements BlogService {

    /**
     *
     * 在所有的基础方法当中我们做出如下约定,(因为有大量的请求是需要使用到分页查询的,并且这个方法相当重要)
     * key,表示需要模糊查询或者精确查询的值,和 accurate 相互配合。
     * accurate表示改查询需要进行精确查询 当accurate=single 表示精确查询,需要指定
     * table_name 还有order:desc,asc当为many,表示需要更加复杂的查询,此时需要附带 accurate_query 即查询QueryWrapper
     * 所有的附加值都需要具备
     * 最后必须参数为
     * 'page': 第几页
     * 'limit':每页多少,
     * 此外对于用户端的查询,需要指明status,和 level否则处理将失败
     * */

    @Override
    public PageUtils queryPage(Map<String, Object> params) throws Exception {
        String key = (String) params.get("key");
        String accurate = (String) params.get("accurate");
        IPage<BlogEntity> page_params = new Query<BlogEntity>().getPage(params);
        QueryWrapper<BlogEntity> blogEntityQueryWrapper = new QueryWrapper<>();
        if(key!=null){
            if(accurate==null){
                //此时表示只有key,没有accurate,说明是后台管理系统在调用
                blogEntityQueryWrapper.like("userid",key).or().
                        like("blogid",key).or().
                        like("user_nickname",key).or().
                        like("blog_title",key);
            }else {
                //此时有accurate说明是用户端在调用
                if(accurate.equals("single")){
                    String table_name = (String) params.get("table_name");
                    String order = (String) params.get("order");
                    Integer status = Integer.valueOf((String) params.get("status"));
                    Integer level = Integer.valueOf((String) params.get("level"));
                    if(table_name.equals("HoleNULL")){
                        blogEntityQueryWrapper.eq("status",status)
                                .eq("level",level);
                    }else {
                        blogEntityQueryWrapper.eq(table_name,key)
                                .eq("status",status)
                                .eq("level",level);
                    }

                    if(order.equals("desc")){
                        blogEntityQueryWrapper.orderByDesc("blogid");
                    }

                }else if(accurate.equals("many")){
                    Object accurate_query = params.get("accurate_query");
                    QueryWrapper<BlogEntity> deserialize = (QueryWrapper<BlogEntity>) SerializeUtil.deserialize(accurate_query.toString());
                    blogEntityQueryWrapper = deserialize;
                }
            }
        }
        IPage<BlogEntity> page = this.page(
                page_params,
                blogEntityQueryWrapper
        );

        return new PageUtils(page);
    }

}

这些代码后面在做一个映射封装。

这里的话还有我们的R类:

public class R extends HashMap<String, Object> {
	private static final long serialVersionUID = 1L;
	
	public R() {
		put("code", 0);
		put("msg", "success");
	}
	
	public static R error() {
		return error(HttpStatus.SC_INTERNAL_SERVER_ERROR, "未知异常,请联系管理员");
	}
	
	public static R error(String msg) {
		return error(HttpStatus.SC_INTERNAL_SERVER_ERROR, msg);
	}
	
	public static R error(int code, String msg) {
		R r = new R();
		r.put("code", code);
		r.put("msg", msg);
		return r;
	}

	public static R warn() {
		R r = new R();
		r.put("code", 1);
		r.put("msg", "warning");
		return r;
	}

	public static R ok(String msg) {
		R r = new R();
		r.put("msg", msg);
		return r;
	}
	
	public static R ok(Map<String, Object> map) {
		R r = new R();
		r.putAll(map);
		return r;
	}
	
	public static R ok() {
		return new R();
	}

	public R put(String key, Object value) {
		super.put(key, value);
		return this;
	}
}

博文上传

ok,我们的博文的列表搞定了。

那么就是我们的博文上传了。
这里也是分前后端的。

前端

我们先来看到我们的前端的实现。
这个前端的实现的话,也是,直接看就好了。

这边前端的话其实很眼熟是吧,这边的区别的话,其实就是咱们的文件上传的一个组件。这个组件的话是这样的:

<template>
  <div>
    <el-upload
      :action="dataObj.host"
      :data="dataObj"
      list-type="picture"
      :multiple="false" :show-file-list="showFileList"
      :file-list="fileList"
      :before-upload="beforeUpload"
      :on-remove="handleRemove"
      :on-success="handleUploadSuccess"
      :on-preview="handlePreview">
      <el-button size="small" type="primary">点击上传</el-button>
      <div slot="tip" class="el-upload__tip">只能上传jpg/png文件,且不超过10MB</div>
    </el-upload>
    <el-dialog :visible.sync="dialogVisible">
      <img width="100%" :src="fileList[0].url" alt="">
    </el-dialog>
  </div>
</template>
<script>
import {getUUID} from "./uuid";
import axios from "_axios@0.26.1@axios";
export default {
  name: 'singleUpload',
  props: {
    urlpolicy: String,
    value: String
  },
  computed: {
    imageUrl() {
      return this.value;
    },
    imageName() {
      if (this.value != null && this.value !== '') {
        return this.value.substr(this.value.lastIndexOf("/") + 1);
      } else {
        return null;
      }
    },
    fileList() {
      return [{
        name: this.imageName,
        url: this.imageUrl
      }]
    },
    showFileList: {
      get: function () {
        return this.value !== null && this.value !== ''&& this.value!==undefined;
      },
      set: function (newValue) {
      }
    }
  },
  data() {
    return {
      dataObj: {
        policy: '',
        signature: '',
        key: '',
        ossaccessKeyId: '',
        dir: '',
        host: '',
        // callback:'',
      },
      dialogVisible: false
    };
  },
  methods: {
    emitInput(val) {
      this.$emit('input', val)
    },
    handleRemove(file, fileList) {
      this.emitInput('');
    },
    handlePreview(file) {
      this.dialogVisible = true;
    },
    beforeUpload(file) {

      let _self = this;
      return new Promise((resolve, reject) => {
        // 请求后端(请求地址和后端访问地址一样)
        let urlPol = _self.urlpolicy;
        if(!urlPol){
          urlPol = '/third-part/oss/policy'
        }
        axios
          .get(urlPol)
          .then(response => {
            console.log("这是什么${filename}");
            response = response.data;

            resolve(true);
          })
          .catch(function (error) {
            alert(error)
            console.log("出错了...",err)
            reject(false);
          })
      });
    },
    handleUploadSuccess(res, file) {
      console.log("数据获取为",this.dataObj)
      console.log("上传成功...")
      let url = this.dataObj.host + '/' + this.dataObj.key.replace("${filename}",file.name);
      this.showFileList = true;
      this.fileList.pop();
      this.fileList.push(
        {
          name: file.name,
          url: url
        }
      );
      this.$emit('urlImg',url)
      this.emitInput(this.fileList[0].url);
    }
  }
}
</script>
<style>

</style>

那么这边的话,我们就完成了我们的前端。

之后是后端。

后端

我们的后端分几个部分,首先是我们的这个获取OSS签名,但是这个的话,我们前面说过,这里不重复,那么之后的话,我们这边来看到这个接口:

@RestController
@RequestMapping("/blog/up")
public class BlogUpController {

    @Autowired
    BlogUpService blogUpService;
    @PostMapping("/blogUp")
    @NeedLogin
    public R blogUp(@Validated @RequestBody UpBlogEntity upBlogEntity){
        return blogUpService.blogUp(upBlogEntity);
    }


}

登录验证

那么我们这边的话,有一个自定义注解:

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface NeedLogin {
    String value() default "";
}

/**
 * 负责专门校验,用户有没有登录用的
 * 1. 当前主要负责校验token是否合法
 * */
@Component
@Aspect
@Slf4j
public class VerificationAspect {

    @Autowired
    RedisUtils redisUtils;

    @Pointcut("@annotation(com.huterox.common.holeAnnotation.NeedLogin)")
    public void verification() {}

    /**
     * 环绕通知 @Around ,当然也可以使用 @Before (前置通知)  @After (后置通知)就算了
     * @param proceedingJoinPoint
     * @return
     * 我们这里再直接抛出异常,反正有那个谁统一异常类
     */

    @Around("verification()")
    public Object verification(ProceedingJoinPoint proceedingJoinPoint) throws Throwable{

        RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
        ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) requestAttributes;
        assert servletRequestAttributes != null;
        HttpServletRequest request = servletRequestAttributes.getRequest();

        //正常逻辑是先进行伪参数验证这里先不做

        //分登录的设备进行验证
        String loginType = request.getHeader("loginType");
        String userid = request.getHeader("userid");
        String tokenUser = request.getHeader("loginToken");
        String tokenKey = RedisTransKey.getTokenKey(userid + ":" + loginType);
        if(tokenUser==null || userid==null || loginType==null){
            throw new BadLoginParamsException();
        }
        if(redisUtils.hasKey(tokenKey)){
            if(loginType.equals(LoginType.PcType)){
                Object o = redisUtils.get(tokenKey);
                LoginToken loginToken = JSON.parseObject(o.toString(), LoginToken.class);
                if(!loginToken.getPcLoginToken().equals(tokenUser)){
                    throw new BadLoginTokenException();
                }
            }else if (loginType.equals(LoginType.MobileType)){
                Object o = redisUtils.get(tokenKey);
                LoginToken loginToken = JSON.parseObject(o.toString(), LoginToken.class);
                if(!loginToken.getMobileLoginToken().equals(tokenUser)){
                    throw new BadLoginTokenException();
                }
            }
        }else {
            throw new NotLoginException();
        }

        return proceedingJoinPoint.proceed();
    }
}

这个玩意的原理很简单就是看用户携带的token和我们redis里面的对不对得到,正常情况下,如果用户恶意修改token,校验都是过不了的,除非我服务器有内鬼。
之后的话这里还定义了几个异常。

public class NotLoginException extends RuntimeException{
    public NotLoginException(){}
    public NotLoginException(String message){
        super(message);
    }
}

都是Runtime异常,这里就不复述了。

博文上传

之后的话,我们就可以上传了。
首先是我们和前端交互的数据请求类。

@Data
@AllArgsConstructor
@NoArgsConstructor
public class UpBlogEntity {

    @NotEmpty(message = "userid不能为空")
    private String userid;
    @NotEmpty(message = "quizTitle不能为空")
    @Length(min = 10,message="长度不能低于10个字符")
    private String blogTitle;
    //文章的Markdown文档
    @NotEmpty(message = "context不能为空")
    @Length(min = 100,message="长度不能低于10个字符")
    private String context;
    @Length(min = 4,max = 100,message="长度不能低于10个字符")
    private String info;
    @NotNull
    private Integer level=1;
    @NotNull
    private Integer blogtype=1;
}

之后的话就是我们的实际业务了。

   @Override
    public R blogUp(UpBlogEntity entity) {
        String userid = entity.getUserid();
        String backMessage = "success";
        //接口限流
        if(redisUtils.hasKey(RedisTransKey.getBlogUpKey(entity.getUserid()))){
            return R.error(BizCodeEnum.OVER_UPBLOG.getCode(), BizCodeEnum.OVER_UPBLOG.getMsg());
        }
        R info = feignUserService.info(userid);
        String userString = FastJsonUtils.toJson(info.get("user"));
        UserEntity user = FastJsonUtils.fromJson(userString, UserEntity.class);
        if(user!=null){
            String context = entity.getContext();
            String blogInfo = entity.getInfo();
            /**
             * 先对context和bloginfo进行校验,是否为存在不友好的信息
             * */
            int countContext = wordFilter.wordCount(context);
            int countInfo = wordFilter.wordCount(blogInfo);
            int status = 1;
            //博文的摘要过滤,只要摘要没有过,直接先打回去!
            if(countInfo>=blogInfo.length()*threshold){
                return R.error(BizCodeEnum.BAD_BLOGINFO.getCode(),BizCodeEnum.BAD_BLOGINFO.getMsg());
            }
            //博文内容的过滤
            if(countContext>=context.length()*threshold){
                return R.error(BizCodeEnum.BAD_CONTEXT.getCode(),BizCodeEnum.BAD_CONTEXT.getMsg());
            }else if (countContext>0&&countContext<context.length()*threshold){
                backMessage="哇!您的提交直接通过了呢!";
            }else {
                status = 2;
                context = wordFilter.replace(context, '*');
                backMessage="您的提问已提交,正在等待审核哟!";
            }
            //预存储content
            ContentEntity contentEntity = new ContentEntity();
            contentEntity.setContent(context);
            contentEntity.setVersion("1.0");
            contentEntity.setCreateTime(DateUtils.getCurrentTime());
            contentService.save(contentEntity);
            Long contentid = contentEntity.getContentid();
            //预存储博文
            BlogEntity blogEntity = new BlogEntity();
            blogEntity.setBlogTitle(entity.getBlogTitle());
            blogEntity.setLevel(entity.getLevel());
            blogEntity.setBlogtype(entity.getBlogtype());
            //查询用户的头像信息
            R RHeadImg = feignHeadimgService.headimg(userid);
            String headImgString = FastJsonUtils.toJson(RHeadImg.get("headimg"));
            final HeadimgEntity headimg = FastJsonUtils.fromJson(headImgString, HeadimgEntity.class);
            if(headimg!=null){
                blogEntity.setUserImg(headimg.getImgpath());
            }
            blogEntity.setCreateTime(DateUtils.getCurrentTime());
            blogEntity.setUserNickname(user.getNickname());
            blogEntity.setUserid(userid);
            blogEntity.setStatus(status);
            blogEntity.setInfo(blogInfo);
            blogService.save(blogEntity);
            Long blogid = blogEntity.getBlogid();

            //完成正式存储
            contentEntity.setBlogid(blogid);
            blogEntity.setContentid(contentid);
            blogService.updateById(blogEntity);
            contentService.updateById(contentEntity);
            /**
             * 更新用户日志
             * */
            LogActicleEntity logActicleEntity = new LogActicleEntity();
            logActicleEntity.setAction(1);
            logActicleEntity.setUserid(userid);
            logActicleEntity.setArticleid(blogEntity.getBlogid());
            logActicleEntity.setArticleTitle(blogEntity.getBlogTitle());
            logActicleEntity.setCreteTime(blogEntity.getCreateTime());
            feignLogActicleService.save(logActicleEntity);
            /**
             * 设置标志
             */
            redisUtils.set(RedisTransKey.setBlogUpKey(entity.getUserid())
                    ,.1,10, TimeUnit.MINUTES
            );
        }else{
            return R.error(BizCodeEnum.NO_SUCHUSER.getCode(),BizCodeEnum.NO_SUCHUSER.getMsg());
        }
        return R.ok(backMessage);
    }

这里的话基本上都是调用dao或者是远程的微服务进行存储,没啥亮点。之后的话就是上seate。搞分布式事务。

博文显示

终于到了这里了,这个部分其实也不难,还是我们的前端(这里的话还有些接口,我就不说了,重点是加载文章内容)

前端

这里面的刷新有点问题,这里在我们的项目里面,所以的话有些东西只能先这样写了。不然有bug,问题在我们的项目里面,改的话后面再说,也是个小问题。

后端

首先是我们的返回类:

@Data
@AllArgsConstructor
@NoArgsConstructor
public class BlogBody implements Serializable {
    private static final long serialVersionUID = 1L;
    /**
     * 这边的话userid啥的都是指文章的作者
     * */
    private String userid;
    private Long blogid;
    private String content;
    private String blogTitle;
    private String userNickname;
    private String userImg;
    private String createTime;
    private Integer viewNumber;
    private Integer likeNumber;
    private Integer collectNumber;
    private Integer forkNumber;
    private String blogtype;
    private String blogimg;

}

这个就是我们的返回类

那么我们要做的其很简单,组合就好了。

    @Override
    public R blogById(Long blogById) {
        BlogEntity blog = blogService.getById(blogById);
        ContentEntity content = contentService.getOne(new QueryWrapper<ContentEntity>().eq("blogid", blog.getBlogid())
                .orderByDesc("contentid")
                .last("limit 0,1")
        );
        if(blog==null){
            return R.error(BizCodeEnum.NO_SUCHBLOG.getCode(),BizCodeEnum.NO_SUCHBLOG.getMsg());
        }
        if(content==null){
            return R.error(BizCodeEnum.NO_SUCHCONTENT.getCode(), BizCodeEnum.NO_SUCHCONTENT.getMsg());
        }
        BlogBody blogBody = new BlogBody();
        BeanUtils.copyProperties(blog,blogBody);
        blogBody.setContent(content.getContent());
        blogBody.setBlogtype(BlogType.BLOGTYPE.get(blog.getBlogtype()));
        return R.ok().put("blog",blogBody);
    }

总结

到月末了,冲个活动业绩,下个月更新超过5篇算我输(狗头)
