我对 ejs 不是很熟悉，我正在做一个使用它的实践项目。它以某种方式呈现除图像之外的所有内容。它使用来自快速会话的图像，但我什至尝试用确切的网址替换它，但它仍然不起作用。
这是app.js文件
//Imports
const path = require("path");
require("dotenv").config();
const express = require('express');
const morgan = require('morgan');
const helmet = require('helmet');
const partials = require('express-partials');
const app = express();
const session = require('express-session');
const passport = require('./config/passport.js');
//Variables
const PORT = 3000;
const EXPRESS_SESSION_SECRET = process.env.EXPRESS_SESSION_SECRET;
//Remove after development to minimize unnecessary realtime logs on server
app.use(morgan('tiny'));
//Express setup
app.use(express.json());
app.use(helmet());
app.disable('x-powered-by');
//Express page setup
app.set('views', path.join(__dirname + '/views'));
app.set('view engine', 'ejs');
app.use(partials());
app.use(express.static(path.join(__dirname + '/public')));
//Express session set up to be used on all routes
app.use(
session({
secret: EXPRESS_SESSION_SECRET,
resave: false,
saveUninitialized: false,
cookie: { maxAge: 1000 * 60 *60 * 24 }
})
);
//Initializes passport to be used on all routes
app.use(passport.initialize());
app.use(passport.session());
//Mounts the page router
const pageRouter = require('./routers/page-router.js');
app.use('/', pageRouter);
//Mounts the api router
const apiRouter = require('./routers/api-router.js');
app.use('/api', apiRouter);
//Starts server
app.listen(PORT, () => console.log(`Listening on ${PORT}`));
这是路由器中的路由，到 /account 的 GET 路由是我们感兴趣的一个
//Imports necessary modules
const express = require('express');
const {ensureAuthenticated} = require('../middleware/auth-middleware.js');
//Creates the router
const pageRouter = express.Router();
//This page is protected and requires github authentication
pageRouter.get('/account', ensureAuthenticated, (req, res) => {
res.render('account', { user: req.user });
});
//Exports the router
module.exports = pageRouter;
最后是位于views 文件夹中的ejs 文件。所有其他数据（例如名称和链接）都正确填充，即使使用实际的 url，我也无法获取要渲染的图像
<div class="row">
<div class="six columns">
<h1><%= user.username %></h1>
<p>ID: <%= user.id %></p>
<p>Name: <%= user.displayName %></p>
<p>Bio: <%= user._json.bio %></p>
<p>GitHub: <a href="<%= user._json.html_url %>">Link</a></p>
</div>
<div class="six columns">
<img src="<%= user.photos[0].value %>" alt="Avatar">
</div>
</div>
任何帮助或指导都将非常感激，提前致谢！
编辑：
这里是源代码中的 html，它看起来有效并且可以单独工作。我不知道为什么它在我的应用程序提供服务时无法正确呈现。

首先，检查用户obj是否存在。
然后，检查用户 obj 键。
