折腾博客之通过Freshrss API实现朋友文章

7-28-2024

之前玩静态博客用过hexo-circle-of-friends来获取友情链接中的好友文章. 如今这个项目我部署的过程中总是出现各种意外,不想继续折腾了,于是想起在大佬处看到用FreshRSS 实现友圈rss订阅于是开始今日的折腾

Docker部署Freshrss

使用docker run 命令

docker run -d --restart unless-stopped --log-opt max-size=10m \
  -p 8282:80 \
  -e TZ=Asia/Shanghai \
  -e 'CRON_MIN=1,31' \
  -v /root/rss/data:/var/www/FreshRSS/data \
  -v /root/rss/extensions:/var/www/FreshRSS/extensions \
  --name freshrss \
  freshrss/freshrss

获取API密码

在认证中打开允许 API 访问（用于手机应用）选项
在账户-API管理中输入API密码

CF Workers

这时候就要使用CF大法了.

addEventListener('fetch', event => {
    event.respondWith(handleRequest(event.request));
});

const siteurl = 'Freshssr地址';

async function handleRequest(request) {
    // 直接使用固定的用户名与密码
    const user = '用户名';
    const password = 'API密码';
    try {
        const authToken = await login(user, password);
        if (!authToken) {
            return new Response('Login failed.', { status: 403 });
        }

        const articles = await fetchArticles(authToken);
        const subscriptions = await fetchSubscriptions(authToken);
        const formattedArticles = formatArticles(articles, subscriptions);

        return new Response(JSON.stringify(formattedArticles, null, 2), {
            headers: { 'Content-Type': 'application/json' }
        });
    } catch (error) {
        return new Response('Error: ' + error.message, { status: 500 });
    }
}

async function login(user, password) {
    const loginUrl = `${siteurl}/api/greader.php/accounts/ClientLogin?Email=${encodeURIComponent(user)}&Passwd=${encodeURIComponent(password)}`;
    const response = await fetch(loginUrl);
    const text = await response.text();
    const match = text.match(/Auth=(.*)/);
    return match ? match[1] : null;
}

async function fetchArticles(authToken) {
    const articlesUrl = `${siteurl}/api/greader.php/reader/api/0/stream/contents/reading-list?&n=1000`;
    const response = await fetch(articlesUrl, {
        headers: {
            'Authorization': `GoogleLogin auth=${authToken}`
        }
    });
    const data = await response.json();
    return data.items || [];
}

async function fetchSubscriptions(authToken) {
    const subscriptionsUrl = `${siteurl}/api/greader.php/reader/api/0/subscription/list?output=json`;
    const response = await fetch(subscriptionsUrl, {
        headers: {
            'Authorization': `GoogleLogin auth=${authToken}`
        }
    });
    const data = await response.json();
    return data.subscriptions || [];
}

function formatArticles(articles, subscriptions) {
    const subscriptionMap = new Map();
    subscriptions.forEach(subscription => {
        subscriptionMap.set(subscription.id, subscription);
    });

    return articles.map(article => {
        const strippedContent = stripHtml(article.summary.content);
        const desc_length = strippedContent.length;
        const short_desc = desc_length > 20
            ? strippedContent.substring(0, 99) + '...'
            : strippedContent;

        const subscriptionId = article.origin.streamId;
        const subscription = subscriptionMap.get(subscriptionId);

        return {
            site_name: article.origin.title,
            title: article.title,
            link: article.alternate[0].href,
            time: new Date(article.published * 1000).toISOString(), // Convert timestamp to ISO string
            description: short_desc,
            icon: subscription ? `${siteurl}/${subscription.iconUrl.split('/').pop()}` : ''
        };
    });
}

function stripHtml(html) {
    return html.replace(/<[^>]*>?/gm, ''); // 使用正则表达式去除HTML标签
}

访问看看,输出 https://rss.imsun.workers.dev/ 由于cf的加载速度不是很理想,当然也可以使用php或者bash脚本生成json文件,这样可以加速页面加载的速度,大佬已经有代码贴出来了我就不复制了. 如果是使用静态博客的话则可以选择使用github工作流生成静态文件并通过vercel加速访问

调用

我把朋友圈文章加在了友情链接页面

使用php

<?php
// 获取JSON数据
$jsonData = file_get_contents('https://rss.imsun.workers.dev/');

// 检查是否成功获取数据
if ($jsonData === false) {
    die('Error fetching JSON data.');
}

// 将JSON数据解析为PHP数组
$articles = json_decode($jsonData, true);

// 检查是否成功解析JSON
if ($articles === null) {
    die('Error decoding JSON data.');
}

// 对文章按时间排序（最新的排在前面）
usort($articles, function ($a, $b) {
    return strtotime($b['time']) - strtotime($a['time']);
});

// 设置每页显示的文章数量
$itemsPerPage = 30;

// 生成文章列表
echo '<header class="archive--header"><h1 class="post--single__title">朋友文章</h1><h2 class="post--single__subtitle">通过Freshrss获取 </h2>
</header><div class="articleList">';
foreach (array_slice($articles, 0, $itemsPerPage) as $article) {
    // 格式化发布时间
    $date = new DateTime($article['time']);
    $date->setTimezone(new DateTimeZone('Asia/Shanghai')); // 设置为中国上海时区
    $formattedDate = $date->format('Y年m月d日 H:i:s');

    echo '<article class="post--item"><div class="content">';

    echo '<a target=_blank href="' . htmlspecialchars($article['link']) . '"><h2 class="post--title">' . htmlspecialchars($article['title']) . '</h2></a>';
    echo ' <div class="description">' . htmlspecialchars($article['description']) . '</div>';
    echo '<div class="meta"><img src="' . htmlspecialchars($article['icon']) . '"  class="icon" width="16" height="16" alt="Icon" />'. htmlspecialchars($article['site_name']) .'';
    echo '<svg class="icon" viewBox="0 0 1024 1024" width="16" height="16">
    <path
        d="M512 97.52381c228.912762 0 414.47619 185.563429 414.47619 414.47619s-185.563429 414.47619-414.47619 414.47619S97.52381 740.912762 97.52381 512 283.087238 97.52381 512 97.52381z m0 73.142857C323.486476 170.666667 170.666667 323.486476 170.666667 512s152.81981 341.333333 341.333333 341.333333 341.333333-152.81981 341.333333-341.333333S700.513524 170.666667 512 170.666667z m36.571429 89.697523v229.86362h160.865523v73.142857H512a36.571429 36.571429 0 0 1-36.571429-36.571429V260.388571h73.142858z">

    </div> ';

    echo '</article>';
}
echo '</div>';
?>

大功告成

使用JS

<div class="articleList" id="articleList"></div>
<button id="load-more">加载更多</button>

<script>
document.addEventListener('DOMContentLoaded', async () => {
    const jsonData = await fetchJsonData('https://cdn.jkjoy.cn/rss/rss.json');
    if (!jsonData) {
        console.error('Failed to fetch JSON data.');
        return;
    }
    const articles = jsonData;

    // 对文章按时间排序（最新的排在前面）
    articles.sort((a, b) => new Date(b.time) - new Date(a.time));

    // 初始化分页变量
    let currentPage = 1;
    const itemsPerPage = 30;

    // 加载第一页文章
    loadArticles(currentPage, itemsPerPage, articles);

    // 设置“加载更多”按钮点击事件
    const loadMoreButton = document.getElementById('load-more');
    loadMoreButton.addEventListener('click', () => {
        currentPage++;
        loadArticles(currentPage, itemsPerPage, articles);
    });
});

async function fetchJsonData(url) {
    try {
        const response = await fetch(url);
        if (response.ok) {
            return await response.json();
        } else {
            console.error('HTTP error:', response.status, response.statusText);
        }
    } catch (error) {
        console.error('Fetch error:', error);
    }
    return null;
}

function loadArticles(page, perPage, articles) {
    const startIndex = (page - 1) * perPage;
    const endIndex = page * perPage;
    const articleListElem = document.getElementById('articleList');

    articles.slice(startIndex, endIndex).forEach(article => {
        const articleElem = createArticleElement(article);
        articleListElem.appendChild(articleElem);
    });
}

function createArticleElement(article) {
    // 格式化发布时间
    const date = new Date(article.time);
    const formattedDate = new Intl.DateTimeFormat('zh-CN', {
        year: 'numeric',
        month: '2-digit',
        day: '2-digit',
        hour: '2-digit',
