我正在尝试用express动态更改我的路由，它的确切链接存储在json文件中。我的json存储在articles.js中，看起来像这样：
title: 'title1',
link: 'title2',
creator: 'user1',
createdAt: '17/10/2021',
description: 'Test description',
publish: 'True',
text: 'This is a sample text'
},
{
title: 'title2',
link: 'title2',
creator: 'user3',
createdAt: '17/10/2021',
description: 'Test description',
publish: 'True'
},
{
title: 'title3',
link: 'title3',
creator: 'user2',
createdAt: '17/10/2021',
description: 'Test description',
publish: 'True'
}]
exports.articles = articles;
在我的get-route过程中，我动态地拥有呈现到blog_articles页面的权限，动态地将超链接更改为route\them\title1、\theme\title2等。我的快递路线是这样定义的：
const router = express.Router()
const Articles = require('../articles/articles');
router.get("/", async (req, res) => {
const articles = await Object.values(Articles.articles).filter(all => all.publish ==='True');
res.render("theme", {articles: articles});
});
router.get("/:link", async (req, res) => {
var link = req.params.articles.link
const articles = await Object.values(Articles.articles).filter(all => all.publish ==='True');
res.render("blog_articles", {articles: articles.link});
res.send(articles.link);
res.send(req.params.id);
//const articles = await Object.values(Articles.articles).filter(all => all.publish
});
编辑：这是主题。ejs:
<!DOCTYPE html>
<html lang="en">
<body>
<div class="container px-4 px-lg-5">
<div class="row gx-4 gx-lg-5 justify-content-center">
<div class="col-md-10 col-lg-8 col-xl-7">
<!-- Post preview-->
<div class="post-preview">

<h2 class="post-title" style="margin-bottom: -1.41rem"><a href="futureai/<%=article.link %>", id="Android"><%= article.title %></a></h2>

<br class="post-gap-title-description" style="margin-bottom: 0.25rem">

<p class="post-meta">

使用find获取您需要的文章：
router.get("/:link", async (req, res) => {
var link = req.params.link
const article = Object.values(Articles.articles)
.filter(all => all.publish ==='True')
.find(article => article.link === link)
res.render("blog_articles", {articles: article.link});
// You have already sent a response, following code is useless
// res.send(articles.link);
// res.send(req.params.id);
});
