Express JS 404错误中的新路线

尝试使用Express应用程序生成器将新路线添加到此Express应用程序。 这是app.js文件：

var express = require('express'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var routes = require('./routes/index'); var users = require('./routes/users'); var parse = require('./routes/parse'); var app = express(); // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'jade'); // uncomment after placing your favicon in /public //app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(cookieParser()); app.use(express.static(path.join(__dirname, 'public'))); app.use('/', routes); app.use('/users', users); app.use('/parse', parse); // catch 404 and forward to error handler app.use(function(req, res, next) { var err = new Error('Not Found - from app.js'); err.status = 404; next(err); }); // error handlers // development error handler // will print stacktrace if (app.get('env') === 'development') { app.use(function(err, req, res, next) { res.status(err.status || 500); res.render('error', { message: err.message, error: err }); }); } // production error handler // no stacktraces leaked to user app.use(function(err, req, res, next) { res.status(err.status || 500); res.render('error', { message: err.message, error: {} }); }); module.exports = app; 

我添加的行是：

  var parse = require('./routes/parse'); app.use('/parse', parse); 

然后在/path目录我添加parse.js包含：

 var express = require('express'); var router = express.Router(); router.get('/parse', function(req, res, next) { res.send('return from parse.js'); }); module.exports = router; 

我可以使用浏览器打击/和/用户资源，我得到预期的结果。 但是当我尝试打/parsing我得到这个404：

找不到 – 从app.js

在URL尝试/parse/parse

如果你想使用/parse ，请使用/而不是/routes/parse.js的/parse

请参阅/routes/users.js 。

TL; DR;

 //app.js var parse = require('./routes/parse'); app.use('/parse', parse); var express = require('express'); var router = express.Router(); // routes/parse.js // the URL pattern will be used in conjunction with how its is being used // in this case it would be '/parse' (from app.js) + '/parse' (as used in the next line) // resulting in '/parse/parse' router.get('/parse', function(req, res, next) { res.send('return from parse.js'); }); module.exports = router;
