基本的nodejs路由导致404

Question

I am trying to create two separate routes in NodeJS, I am using the express framework and angular on the client side. 我试图在NodeJS中创建两个单独的路由，我在客户端使用了express框架和angular。 I am currently able to render my index page successfully by visiting localhost:3000/ although when I try to render the login page by visiting localhost:3000/login I am getting a GET /login 404 error and not sure why b/c I set it up extremely similar to the index route. 我目前能够通过访问localhost:3000/成功呈现索引页面，但是当我尝试通过访问localhost:3000/login呈现登录页面时却出现GET /login 404错误，并且不确定为什么我设置了b / c它与索引路由极其相似。 Not sure if I missed something. 不知道我是否错过了什么。

This my app.js 这是我的app.js

    //require dependencies 
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');

//require routes but do not user yet
var routes = require('./routes/index');
var login = require('./routes/login');

//start app
var app = express();


// view engine setup - default views directory
app.set('views', path.join(__dirname, 'views'));
app.locals.delimiters = '<% %>';
app.set('view engine', 'hjs'); //use hogan templating for views

// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(require('less-middleware')(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
app.use('/login', login);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  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;

routes/login.js 路由/login.js

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

router.get('/login', function(req, res){
   res.render('login');
});

module.exports = router;

views/login.hjs views / login.hjs

<!DOCTYPE html>
<html>
<head>

</head>
<body>
  HELLO WORLD
</body>
</html>

Visiting localhost:3000/login renders the following: 访问localhost：3000 / login将显示以下内容：

{{ message }}
{{ error.status }}

{{ error.stack }}

When writing app.use('/login', login) , you are telling Express to use your router under the namespace : '/login'; 在编写app.use('/login', login) ，您要告诉Express在以下名称空间下使用路由器：'/ login'; Therefore, all routes defined into login.js don't need this prefix. 因此，所有在login.js中定义的路由都不需要此前缀。

Try to access localhost:3000/login/login ;) 尝试访问localhost:3000/login/login ;）

Then, just change your router to: 然后，只需将路由器更改为：

router.get('/', function(req, res){
    res.render('login');
});
