Question

我需要了解使用Routes的Express应用程序中的流程如何工作，我有这些路线

app.use(require('./routes/reportsRouter'));
app.use(require('./routes/crewsRouter'));
app.use(require('./routes/api'));
app.use(require('./routes/filesRouter'));

现在在./routes/crewsRouter我有以下代码

var express = require('express');
var router = express.Router(); 
router.use(function(req, res, next) {

  var url = req.url;
  //..... Edit URL if Contains // empty parm 
  // crews//today; correct Url crews/all/today
  // this give me a list of all jobs for all crews for today. 
  console.log("CrewsRouter: ", req.method + ".( " + url + " )");
  next(); 
});
router.get('/crews', function(req, res) {
    if (!req.params.key) { next(); }
    res.render('crewsView',{
        pageTitle:'All-Crews',
        pageID:'crews', 
        crewInfo: {"aka": "all"},
        reqOptions: ''
    });

});
router.get('/crews/:leadId?/:options?', function(req, res) {....}
module.exports = router;

并在reportsRouter.js

中

var express = require('express');
var router = express.Router();

router.use(function(req, res, next) {

    // log each request to the console
    console.log("ReportsRouter: ", req.method + ".( " + req.url + " )");
    // continue doing what we were doing and go to the route
    next(); 
});

router.get('/reports', function(req, res) {
    //var data = req.app.get('appData')

    res.render('reportsView',{
        pageTitle:'Reports',
        pageID:'reports'        
    });
});
module.exports = router;

无论我要求的路线是什么，我所拥有的行为两个route.use都在运行。这是正常的，我该怎么做才能阻止这种行为。

Answer 1

let crewsRouter = require('routes/crewsRouter');
...

app.use('/crews', crewsRouter);
app.use('/reports', reportsRouter);

#cwws

...
router.get('/', function(req, res) {
    ... # this used to be your '/crews' handler
}

#reports

...
router.get('/', function(req, res) {
    ... # this used to be your '/reports' handler
}

你应该做这样的事情：

app.use('/reports', require('./routes/reportsRouter'));
app.use('/crews', require('./routes/crewsRouter'));
app.use('/api', require('./routes/api'));
app.use('/files', require('./routes/filesRouter'));

然后在reportsRouter：

var express = require('express');
var router = express.Router();

router.use(function(req, res, next) {

    // log each request to the console
    console.log("ReportsRouter: ", req.method + ".( " + req.url + " )");
    // continue doing what we were doing and go to the route
    next(); 
});

router.get('/', function(req, res) {
    //var data = req.app.get('appData')

    res.render('reportsView',{
        pageTitle:'Reports',
        pageID:'reports'        
    });
});
module.exports = router;

您的crewsRouter：

var express = require('express');
var router = express.Router(); 
router.use(function(req, res, next) {

  var url = req.url;
  //..... Edit URL if Contains // empty parm 
  // crews//today; correct Url crews/all/today
  // this give me a list of all jobs for all crews for today. 
  console.log("CrewsRouter: ", req.method + ".( " + url + " )");
  next(); 
});
router.get('/', function(req, res) {
    if (!req.params.key) { return next(); }
    res.render('crewsView',{
        pageTitle:'All-Crews',
        pageID:'crews', 
        crewInfo: {"aka": "all"},
        reqOptions: ''
    });
});
router.get('/:leadId?/:options?', function(req, res) {....});
module.exports = router;
