Node.js 使用Docpad'；express应用程序中的渲染引擎

我试图使用docpad在express应用程序中处理渲染，但当尝试访问

/contact

时，请求似乎无限期地挂起

这是我的申请表：

var express = require('express');
var http = require('http');
var app = express();
var cons = require('consolidate');

var server = http.createServer(app).listen(process.env.PORT || 9778);

app.use(app.router);

// Add DocPad to our Application
var docpadInstanceConfiguration = {
    // Give it our express application and http server
    serverExpress: app,
    serverHttp: server,

    // Tell it not to load the standard middlewares (as we handled that above)
    middlewareStandard: false
};

var docpadInstance = require('docpad').createInstance(docpadInstanceConfiguration, function(err){
    if (err)  return console.log(err.stack);

    // Tell DocPad to perform a generation, extend our server with its routes, and watch for changes
    docpadInstance.action('generate server watch', docpadInstanceConfiguration, function(err){
        if (err)  return console.log(err.stack);
    });
});

app.get('/contact', function(req, res) {
    req.templateData = {
      weDidSomeCustomRendering: true
    };
    var d = docpadInstance.getFile({relativePath:'hello.html.md'});
    docpadInstance.serveDocument({document: d, req: req, res: res}, function(){});
});

这几乎是直接从文档中复制的，但不起作用。有什么想法吗？

关键是要通过

下一步

：

app.get('/contact', function(req, res, next) {
    req.templateData = {
      weDidSomeCustomRendering: true
    };
    var d = docpadInstance.getFileAtPath('pages/hello.html');
    docpadInstance.serveDocument({document: d, req: req, res: res}, next);
});
