let context = {title:"api",message:"root"}
res.sendFile(__dirname + '/views/index.html',context)

推荐答案
不使用模板引擎(如jade，ejs，pug或客户端库，例如angular，react).
您无法在html端内插{{title}}的含义.
Without using template engines like jade,ejs, pug or client side libraries like angular, react.
You cannot interpolate the meaning of {{title}} in the html side.
另一种方法是使用javascript从服务器获取详细信息
Another approach is using javascript to fetch the details from server
html文件
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title></title>
</head>
<body>
<div id="test">
</div>
<script type="text/javascript">
let url="http://localhost:8001/test";
fetch(url).then(response => response.json())
.then( (result) => {
console.log('success:', result)
let div=document.getElementById('test');
div.innerHTML=`title: ${result.title}<br/>message: ${result.message}`;
})
.catch(error => console.log('error:', error));
</script>
</body>
</html>
server.js
server.js
app.get('/test',(req,res)=>{
//res.sendFile(__dirname +"/views/test.html",);
res.json({title:"api",message:"root"});
})
app.get('/render',(req,res)=>{
res.sendFile(__dirname +"/views/test.html");
})
