尝试使用Express应用程序生成器向此Express应用程序添加新路由.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,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,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/ routes目录中我添加了包含以下内容的parse.js：
var express = require('express');
var router = express.Router();
router.get('/parse',function(req,next) {
res.send('return from parse.js');
});
module.exports = router;
我可以使用浏览器点击/和/ users资源,我得到了预期的结果.但是当我尝试点击/解析时,我得到这个404：
找不到 – 来自app.js

解决方法
尝试/解析/解析URL
如果你想使用/ parse,请在/routes/parse.js中使用/而不是/ parse
请参考/routes/index.js> /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',next) {
res.send('return from parse.js');
});
module.exports = router;
