|
||
<p> 用户在登录的时候会生成一个随机的字符串(salt)，这个随机的字符串会加到密码后面然后连同密码加密存储到数据库。</p>

<p><img src="/pictures/image-20230811165505210.png" alt="image-20230811165505210"></p>
|
||
<p><strong>登录加盐的过程</strong></p>
|
||
<p> 先根据账号查询是否存在该用户，如果存在的话，根据用户输入的密码和数据库中的salt进行md5加密，并和数据库中的密码比对，一致的话，比对通过，不一样的话不通过。</p>

|

<p>思路分析：</p>
|
||
<ol>
|
||
<li>用户进入网关开始登陆，网关过滤器进行判断，如果是登录，则路由到后台管理微服务进行登录</li>
|
||
<li>用户登录成功，后台管理微服务签发JWT TOKEN信息返回给用户</li>
|
||
<li>用户再次进入网关开始访问，网关过滤器接收用户携带的TOKEN </li>
|
||
<li>网关过滤器解析TOKEN ，判断是否有权限，如果有，则放行，如果没有则返回未认证错误</li>

<p>通过nginx来进行配置，功能如下</p>
|

<ul>
|

<p>在nginx安装的conf目录下新建一个文件夹<code>leadnews.conf</code>,在当前文件夹中新建<code>heima-leadnews-app.conf</code>文件</p>
|
||
<p>heima-leadnews-app.conf配置如下：</p>

|
||
<p><strong>优势：</strong></p>
|
||
<ol>
|
||
<li><p>减少IO争抢，减少锁表的几率，查看文章概述与文章详情互不影响</p>
|
||
</li>
|
||
<li><p>充分发挥高频数据的操作效率，对文章概述数据操作的高效率不会被操作文章详情数据的低效率所拖累</p>
|
||
</li>
|
||
</ol>
|
||
<p><strong>拆分规则：</strong></p>
|
||
<p>1.把不常用的字段单独放在一张表</p>
|
||
<p>2.把text，blob等大字段拆分出来单独放在一张表</p>
|
||
<p>3.经常组合查询的字段单独放在一张表中</p>

<p><strong>踩坑</strong>: 在导入项目的时候提示Caused by: java.io.FileNotFoundException: class path resource [com/heima/apis/article/IArticleClient.class] cannot be opened because it does not exist ，先删除这个项目，手动创建这个项目，然后复制资料里面文件到这个项目即可，直接复制整个项目可能会报这个错!</p>

<p><strong>代码实现</strong></p>
|
||
<p>1.在文章模块的pom.xml文件中加入以下的依赖</p>
|
||
<figure class="highlight xml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br></pre></td><td class="code"><pre><span class="line"><span class="tag"><<span class="name">dependencies</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">dependency</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">groupId</span>></span>org.springframework.boot<span class="tag"></<span class="name">groupId</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">artifactId</span>></span>spring-boot-starter-freemarker<span class="tag"></<span class="name">artifactId</span>></span></span><br><span class="line"> <span class="tag"></<span class="name">dependency</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">dependency</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">groupId</span>></span>com.heima<span class="tag"></<span class="name">groupId</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">artifactId</span>></span>heima-file-starter<span class="tag"></<span class="name">artifactId</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">version</span>></span>1.0-SNAPSHOT<span class="tag"></<span class="name">version</span>></span></span><br><span class="line"> <span class="tag"></<span class="name">dependency</span>></span></span><br><span class="line"><span class="tag"></<span class="name">dependencies</span>></span></span><br></pre></td></tr></table></figure>
|

|
||
<p>2.在nacos中有关文章模块的配置中添加以下的内容</p>
|
||
<figure class="highlight yaml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br></pre></td><td class="code"><pre><span class="line"><span class="attr">minio:</span></span><br><span class="line"> <span class="attr">accessKey:</span> <span class="string">minio</span></span><br><span class="line"> <span class="attr">secretKey:</span> <span class="string">minio123</span></span><br><span class="line"> <span class="attr">bucket:</span> <span class="string">leadnews</span></span><br><span class="line"> <span class="attr">endpoint:</span> <span class="string">http://192.168.200.130:9000</span></span><br><span class="line"> <span class="attr">readPath:</span> <span class="string">http://192.168.200.130:9000</span></span><br></pre></td></tr></table></figure>

<p>1 自媒体端发布文章后，开始审核文章</p>
|
||
<p>2 审核的主要是审核文章的内容（文本内容和图片）</p>
|
||
<p>3 借助第三方提供的接口审核文本</p>
|
||
<p>4 借助第三方提供的接口审核图片，由于图片存储到minIO中，需要先下载才能审核</p>
|
||
<p>5 如果审核失败，则需要修改自媒体文章的状态，status:2 审核失败 status:3 转到人工审核</p>
|
||
<p>6 如果审核成功，则需要在文章微服务中创建app端需要的文章</p>

<p>1.内容安全接口介绍：</p>
|
||
<p>内容安全是识别服务，支持对图片、视频、文本、语音等对象进行多样化场景检测，有效降低内容违规风险。目前很多平台都支持内容检测，如阿里云、腾讯云、百度AI、网易云等国内大型互联网公司都对外提供了API。</p>

<p>mybatis-plus已经集成了雪花算法，完成以下两步即可在项目中集成雪花算法</p>
|
||
<p>第一：在实体类中的id上加入如下配置，指定类型为id_worker</p>
