<p>一开始想到的是直接调用 Umami API，但现在的 Umami 后台里不一定能很直观地找到 API key。如果为了这两个数字再专门创建一个用户、保存账号密码，又有点重。后来发现 Umami 自带的“分享链接”刚好可以解决这个问题。</p>
<p>这篇文章记录一下完整做法：用 Umami 分享链接拿公开 token，再用 Cloudflare Worker 请求统计接口并缓存，最后给前端信息卡使用。</p>
<h2 id="整体思路">整体思路</h2>
<p>流程大概是这样：</p>
<ol>
<li>在 Umami 后台给站点创建分享链接。</li>
<li>Worker 请求 <code>/api/share/{shareId}</code>，拿到 <code>websiteId</code> 和分享 token。</li>
<li>Worker 带上分享 token 请求 <code>/api/websites/{websiteId}/stats</code>。</li>
<li>Worker 把结果整理成前端需要的 JSON，并用 Cloudflare 缓存 10 分钟。</li>
<li>博客前端请求 Worker 地址，把访客数和访问量填到信息卡。</li>
</ol>
<p>这样做的好处是不用暴露后台账号，也不用在前端直接请求 Umami。前端只会看到 Worker 返回的简洁数据。</p>
<h2 id="创建-umami-分享链接">创建 Umami 分享链接</h2>
<p>进入 Umami 后台，找到对应网站的分享设置，打开需要公开的模块。我这里只需要概览数据，所以勾选“概览”就够了。</p>
<p>保存后会得到一个类似这样的分享链接：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="txt"><code><span class="line"><span>https://umami.example.com/share/Hqx6lIBhIHBR13RY</span></span></code></pre>
<p>最后这一段 <code>Hqx6lIBhIHBR13RY</code> 就是分享 ID，后面 Worker 会用到。</p>
<h2 id="分享链接背后的请求">分享链接背后的请求</h2>
<p>分享页本身不是一个静态 HTML 页面，直接读取页面源码一般拿不到统计数字。它会先请求：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="txt"><code><span class="line"><span>/api/share/Hqx6lIBhIHBR13RY</span></span></code></pre>
<p>这个接口会返回类似这样的数据：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="json"><code><span class="line"><span style="color:#E1E4E8">{</span></span>
<span class="line"><span style="color:#79B8FF"> "shareId"</span><span style="color:#E1E4E8">: </span><span style="color:#9ECBFF">"..."</span><span style="color:#E1E4E8">,</span></span>
<span class="line"><span style="color:#79B8FF"> "shareType"</span><span style="color:#E1E4E8">: </span><span style="color:#79B8FF">1</span><span style="color:#E1E4E8">,</span></span>
<span class="line"><span style="color:#79B8FF"> "websiteId"</span><span style="color:#E1E4E8">: </span><span style="color:#9ECBFF">"3d97b310-b241-4fc6-bc9c-68e317fc7d42"</span><span style="color:#E1E4E8">,</span></span>
<span class="line"><span style="color:#79B8FF"> "token"</span><span style="color:#E1E4E8">: </span><span style="color:#9ECBFF">"..."</span></span>
<span class="line"><span style="color:#E1E4E8">}</span></span></code></pre>
<p>然后访问统计接口时，需要带两个请求头：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="txt"><code><span class="line"><span>x-umami-share-context: 1</span></span>
<span class="line"><span>x-umami-share-token: 上一步返回的 token</span></span></code></pre>
<p>统计接口是：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="txt"><code><span class="line"><span>/api/websites/{websiteId}/stats?startAt=0&#x26;endAt=当前时间戳</span></span></code></pre>
<p>返回结果大概是：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="json"><code><span class="line"><span style="color:#E1E4E8">{</span></span>
<span class="line"><span style="color:#79B8FF"> "pageviews"</span><span style="color:#E1E4E8">: </span><span style="color:#79B8FF">2</span><span style="color:#E1E4E8">,</span></span>

<span class="line"><span style="color:#E1E4E8">}</span></span></code></pre>
<p>其中：</p>
<ul>
<li><code>visitors</code> 是访客数</li>
<li><code>pageviews</code> 是页面访问量</li>
<li><code>visits</code> 是访问会话数</li>
</ul>
<p>网站信息卡里我只用 <code>visitors</code> 和 <code>pageviews</code>。</p>

<h2 id="配置-worker-变量">配置 Worker 变量</h2>
<p>在 Cloudflare Worker 的设置里添加变量：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="txt"><code><span class="line"><span>UMAMI_BASE_URL = https://umami.example.com</span></span>
<span class="line"><span>UMAMI_SHARE_ID = Hqx6lIBhIHBR13RY</span></span>
<span class="line"><span>ALLOWED_ORIGIN = https://blog.example.com</span></span>
<span class="line"><span>CACHE_TTL_SECONDS = 600</span></span></code></pre>
<p>如果你更想直接填完整分享链接，也可以不用 <code>UMAMI_SHARE_ID</code>，改用：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="txt"><code><span class="line"><span>UMAMI_SHARE_URL = https://umami.example.com/share/Hqx6lIBhIHBR13RY</span></span></code></pre>
<p><code>CACHE_TTL_SECONDS = 600</code> 表示缓存 10 分钟。这样访客每次打开页面时，不会都去打 Umami 接口。</p>
<p>如果你只想统计某个建站时间之后的数据，可以额外设置：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="txt"><code><span class="line"><span>STATS_START_AT = 1735660800000</span></span></code></pre>
<p>这个值是毫秒时间戳。不设置的话默认从 <code>0</code> 开始，也就是统计全部数据。</p>
<h2 id="部署方式">部署方式</h2>
<p>如果只是单个 Worker，最简单的方法是在 Cloudflare 后台新建 Worker，然后把 JS 代码直接粘到在线编辑器里。</p>
<p>如果遇到这样的提示：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="txt"><code><span class="line"><span>此上传程序暂不支持需要构建过程的项目。至少找到了一个 JavaScript 文件。请改用 wrangler deploy 以获得完整功能支持。</span></span></code></pre>
<p>通常是因为你上传了整个项目目录。这个场景不需要上传整个博客项目，只需要把 Worker 的 JS 内容粘进去即可。</p>
<p>如果想用 Wrangler，也可以写一个配置文件：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="toml"><code><span class="line"><span style="color:#E1E4E8">name = </span><span style="color:#9ECBFF">"umami-site-stats"</span></span>

<span class="line"><span style="color:#E1E4E8">compatibility_date = </span><span style="color:#9ECBFF">"2026-06-19"</span></span>

<h2 id="测试-worker">测试 Worker</h2>
<p>部署好之后，直接访问 Worker 地址，正常会看到：</p>

<p>如果返回 502，可以先看 <code>message</code> 字段。常见原因有：</p>
<ul>
<li><code>UMAMI_SHARE_ID</code> 写错</li>
<li><code>UMAMI_BASE_URL</code> 写错</li>
<li>分享链接没有保存成功</li>
<li>Umami 的分享权限里没有勾选“概览”</li>
</ul>
<h2 id="接入网站信息卡">接入网站信息卡</h2>
<p>前端信息卡里，静态数据可以直接由博客生成：</p>
<ul>
<li>文章数目：读取文章列表长度</li>
<li>本站总字数：遍历文章内容统计</li>
<li>最后更新时间：取最新文章发布时间</li>
</ul>
<p>访客数和访问量则用 Worker 动态填充。页面里先渲染占位：</p>

<p>我这里还在浏览器端加了一层 <code>localStorage</code> 缓存，缓存 key 里带上 Worker 地址，防止以后更换接口后还读到旧数据：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="js"><code><span class="line"><span style="color:#F97583">const</span><span style="color:#79B8FF"> cacheKey</span><span style="color:#F97583"> =</span><span style="color:#9ECBFF"> `site-info-stats:${</span><span style="color:#E1E4E8">endpoint</span><span style="color:#9ECBFF">}`</span><span style="color:#E1E4E8">;</span></span>
<span class="line"><span style="color:#F97583">const</span><span style="color:#79B8FF"> cacheDuration</span><span style="color:#F97583"> =</span><span style="color:#79B8FF"> 10</span><span style="color:#F97583"> *</span><span style="color:#79B8FF"> 60</span><span style="color:#F97583"> *</span><span style="color:#79B8FF"> 1000</span><span style="color:#E1E4E8">;</span></span></code></pre>
<p>这样前端和 Worker 都有缓存，访问体验会稳一些。</p>
<h2 id="最后">最后</h2>
<p>这个方案的核心是：不要把 Umami 后台账号放到前端，也不需要专门创建只读用户。既然 Umami 分享页本身已经提供了公开数据访问方式，就让 Worker 代替前端去请求它，并顺手做缓存和字段整理。</p>
<p>最终网站信息卡只需要关心这几个字段：</p>
<pre class="astro-code github-dark" style="background-color:#24292e;color:#e1e4e8; overflow-x: auto; white-space: pre-wrap; word-wrap: break-word;" tabindex="0" data-language="json"><code><span class="line"><span style="color:#E1E4E8">{</span></span>
