Question

我有一个路由器，对于某些变量，它会保持params未定义。这些特定的变量在我的数据库中被定义为某些东西，但我不是在查询它，所以我不知道最近发生了什么。例如：

    router.get('/:variable', function(req,res) {
      console.log(req.params.variable);
})

如果我将'85268'设置为变量并且它存在于我的数据库中，它将控制日志未定义。但'85267'不是，它会正常控制。但正如你所看到的，我甚至不是用这个变量查询数据库，但似乎它以某种方式链接。我正在使用Mongoose来模拟我的模式。

编辑：以下是一些代码文件：

app.js

var express = require('express');
var app = express();
var port = process.env.PORT || 8081;
var index = require('./routes/index');
var sites = require('./routes/sites');
var all = require('./routes/all');
var mongoose = require('mongoose');
var redirect = require('./routes/redirect');
app.engine('html',require('ejs').renderFile);
app.set('view engine', 'html');
mongoose.connect('mongodb://localhost/data2');
app.use('/', index);
app.use('/new',sites);
app.use('/all',all);
app.get('/delete',function(req,res){

    var urlModel = require('./dbstuff/url.js');
    urlModel.remove({},function(err,info){
        if (err) throw err;
        else{
            res.send("All deleted");
        }
    });
})
app.use('/short/:id',redirect);


app.listen(port);

sites.js

 var express = require('express');
    var router = express.Router();
    var url = require('url');
    var validator = require('validator');
    var mongoose = require('mongoose');
    var urls = require('../dbstuff/url');
    var bodyParser = require('body-parser');

    router.get('/*', function(req,res){
        var parsed = url.parse(req.path).path.slice(1);
        console.log(parsed);
        if(validator.isURL(parsed,{protocols:['http','https'],require_protocol:true})){

      urls.find({original: parsed},{_id:0, shortened: 1, original: 1},function(err,found){
            if(err) throw err;
            else{
                if(found.length == 0){
                    var newModel = new urls();
                    var newID = Math.floor(Math.random()*(99999))+1;
                    newModel.shortened = "https://urlshortener-gkt5015.c9users.io/short/"+newID;
                    newModel.original = parsed;
                    newModel.save(function(err,data){
                        if(err) throw err;
                        res.json({ original:data.original, shortened:data.shortened,});

                    })
                }
                else{
                    res.json(found[0]);

                }

            }

        });
    }
    else{
        res.send("False");
    }
})

module.exports = router;

redirect.js

     var express = require('express');
var router = express.Router({mergeParams: true});
var mongoose = require('mongoose');
var url = require('url');

router.get('/',function(req,res){
    console.log("using the redirect path.....")
    var link = "https://" + req.hostname + req.originalUrl;
    console.log(req.params);
    console.log(link);
    res.send(link);
module.exports = router;

req.params undefined for certain values
