问题描述

我想调用一些异步函数,这些函数可以从我的ejs文件中调用.

I want to call some of my functions which are asynchronous to be called from within my ejs files.

就像我将此功能设置为我的 app.locals.someFunction

Like I have this functions set as my app.locals.someFunction

async someFunction(param){
  let data = await someAsyncStuff();
  // &  other things
  return data;
}

,我想在ejs文件中使用它,如下所示:

and I want to use it inside ejs file as below:

<%
let data = await someFunction()
for(let x of data){%>

   <li><%=x%></li>

<%}%>

如果通过 {async:true} 作为选项传递,则ejs可以实现.但是,当我的视图引擎设置如下所示时,该在哪儿传递呢?

This is possible with ejs if {async:true} is passed as an option. But where exactly should I pass this when my view engine setup is like the following?


//view engine setup
app.engine ('.html', ejs.renderFile);
app.set ('view engine', 'html');

推荐答案

而不是res.render()

instead res.render()

const ejs = require('ejs');
const html = await ejs.renderFile(view, data, {async: true});
res.send(html);

每个包含等待的内容

<body>
    <%- await include(pageView);%>
</body>

现在异步很好

<%
let data = await collection.find().toArray();

for(let x of data){%>

   <li><%=x%></li>

<%}%>
