在ejs模板中使用嵌入式js加载静态文本文件

Question

我目前正在使用 ejs 视图模板开发 nodejs 应用程序。我试图通过模板中的嵌入式 js 调用存储在文本文件中的大量文本。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
at eval (eval at compile (D:\Web Projects\NodeJs Test\node_modules\ejs\lib\ejs.js:618:12), <anonymous>:30:7)
at returnedFn (D:\Web Projects\NodeJs Test\node_modules\ejs\lib\ejs.js:653:17)

at D:\Web Projects\NodeJs Test\index.js:14:9
at Layer.handle [as handle_request] (D:\Web Projects\NodeJs Test\node_modules\express\lib\router\layer.js:95:5)

有谁知道如何正确地做到这一点？谢谢

不幸的是，无法在 ejs 中要求模块。您也可以尝试在快递部分加载文件。

//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>

否则你可以将 fs 作为脚本嵌入并在文档完成时加载它，但我想这种方法应该更有效。
