Question

我有以下示例中间件组件，我想在index.jade文件中显示。这可能吗？如何在Jade模板中添加req.requestTime？

var requestTime = function (req, res, next) {
  req.requestTime = Date.now();
  next();
};

app.use(requestTime);

Answer 1

将属性添加到res.locals，您可以在Pug（以前的Jade）中使用它

var requestTime = function (req, res, next) {
  req.requestTime = Date.now();
  res.locals.requestTime = req.requestTime;
  next();
};

var requestTime = function (req, res, next) {
    req.requestTime = Date.now();
      res.locals.requestTime = req.requestTime;
      next();
};

//Jade renderer
var jadeRenderer = function(req, res) {
    var jadeFile = 'path/to/jade/template';
    var jadeVars = {
        locals: req.locals,
        queryParams: req.query //if you desire?
    };
    res.render(jadeFile, jadeVars, function(err, html) {
        if(err) {
            //handle error
        }
        res.send(html);
    });
};

//jade template
<p>#{locals.requestTime}</p>
