Expressjs将动态大写和间隔路径路径转换为连字符和小写路径

Question

我遇到了一个问题，我正在尝试使用＆＃34;标题＆＃34;来自我的mongoosedb文档的属性作为文档路径，但所有字符都是小写的，空格用连字符替换。我之前尝试使用过解决方案，但无法生成我的视图，而且Url包含大写字母和％20的空格。

以下是我当前的设置重点是'/blog/:blogpost_title'路线：

routes.js：

var express = require('express');
var router = express.Router();
var blogDB = require('../config/blogDB.js');
var Blogpost = require('./models/blogModel.js');
var paginate = require('express-paginate');

//index 
router.use(paginate.middleware(10, 50));




    router.route('/') 


        // START GET method
        .get(function(req, res, next) {

            Blogpost.paginate({}, req.query.page, req.query.limit, function(err, pageCount, blogpost, itemCount) {




                if (err) return next(err)

                        if (err)
                            res.send(err);


                        blogpost.title = req.body.title; // get the blog title
                        blogpost.author = req.body.author; // get the author name
                        blogpost.tagline = req.body.tagline; // get tagline
                        blogpost.content = req.body.content; // get the blog content

                        res.format({
                            html: function() {
