我目前正在使用 ejs 视图模板开发 nodejs 应用程序。我正在尝试通过模板中的嵌入式 js 调用存储在文本文件中的大批量文本。这是当前模板的代码
<!DOCTYPE html>
<html>
<head>
<link href="/assets/styles/index.css", rel="stylesheet", type="text/css">
</head>
<body>
<% var name = 'A Tale of Two Star Crossed Idiots: Act ' + act%>
<%include partial/header.ejs%>
<p>
//the following line is completely wrong
<%= require('fs').readFileSync('.'+__dirname + '/assets/text/romeo and juliet/act' + act + '.txt') %>
</p>
</body>
</html>
这是我运行它时发生的错误
require is not defined

有谁知道如何正确地做到这一点？ 谢谢。
不幸的是，在 ejs 中要求模块是不可能的。您也可以尝试在快速部分加载文件。
//Node.JS Backend
app.get("/foo",(req,res)=>{
const act = req.query.act; //Act as Query Parameter in URL
fs.readFile('.'+__dirname+'/assets/text/romeo and juliet/act'+act+'.txt',"utf8",(error,data)=>{
//Add your error handling (if(error))
res.render("file",{bar:data});
});
});<!DOCTYPE html>
<html>
<head>
<link href="/assets/styles/index.css", rel="stylesheet", type="text/css">
</head>
<body>
<% var name = 'A Tale of Two Star Crossed Idiots: Act ' + act%>
<%include partial/header.ejs%>
<p>
//the following line is completely wrong
<%- bar %>
</p>
</body>
</html>否则，您可以将 fs 嵌入为脚本并在文档完成后加载它，但我想这种方法应该更有效。
