Express应用-更改基本网址

问题描述

我正在按照此教程一切顺利，但是我需要改变通过配置文件为应用程序提供服务的基本根目录.

I'm building a Q&A app following this tutorial and everything goes well, but I need to change the chance to change the base root where the app is being served via config files.

现在该应用程序在localhost:8080中提供，而我需要在localhost:8080/qae中提供(例如).

Now the app is served in localhost:8080 and I need to be served over localhost:8080/qae (for example).

我认为答案就在这段代码附近:

I think the answer is near this piece of code:

// Setup server
var app = express();
var server = http.createServer(app);
var socketio = require('socket.io')(server, {
  serveClient: config.env !== 'production',
  path: '/socket.io-client'
});
require('./config/socketio')(socketio);
require('./config/express')(app);
require('./routes')(app);


// Start server
function startServer() {
  app.angularFullstack = server.listen(config.port, config.ip, function() {
    console.log('Express server listening on %d, in %s mode '+config.ip, config.port, app.get('env'));
  });
}

setImmediate(startServer);

(来自/server/app.js)

(from /server/app.js)

但是我不知道.可以用简单的方式做到这一点吗?

But I can't figure it. Is it possible doing this in a simple way?

////////EDIT////////

我尝试了所有建议的解决方案，但是我做错了事，但遇到了错误.如果有帮助，这是我的routes.js:

I tried all the proposed solutions, but I'm doing something wrong and got errors. This is my routes.js in case it helps:

/**
 * Main application routes
 */

'use strict';

import errors from './components/errors';
import path from 'path';

export default function(app) {
  // Insert routes below
  app.use('/api/cpd', require('./api/cpd'));
  app.use('/api/categories', require('./api/category'));
  app.use('/api/terms', require('./api/term'));
  app.use('/api/qae', require('./api/qae'));
  app.use('/api/stats', require('./api/stat'));
  app.use('/api/tags', require('./api/tag'));
  app.use('/api/questions', require('./api/question'));
  app.use('/api/things', require('./api/thing'));
  app.use('/api/users', require('./api/user'));

  app.use('/auth', require('./auth'));

  app.use(function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    next();
  });


  // All undefined asset or api routes should return a 404
  app.route('/:url(api|auth|components|app|bower_components|assets)/*')
   .get(errors[404]);

  // All other routes should redirect to the index.html
  app.route('/*')
    .get((req, res) => {
      res.sendFile(path.resolve(app.get('appPath') + '/index.html'));
    });
}

推荐答案

您应该更改此设置的根源:

You should change your rooting to this:

app.use('/qae',require('./routes'))

，在routes/index.js中，您可以拥有路线的所有声明.

and in routes/index.js you can have all declarations of your routes.

在routes.js

export default function(app) {
    // Insert routes below
    app.use('/qae', require('./api'));


    app.use('/auth', require('./auth'));

    app.use(function(req, res, next) {
      res.header("Access-Control-Allow-Origin", "*");
      res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
      next();
    });


    // All undefined asset or api routes should return a 404
    app.route('/:url(api|auth|components|app|bower_components|assets)/*')
    .get(errors[404]);

    // All other routes should redirect to the index.html
    app.route('/*')
      .get((req, res) => {
        res.sendFile(path.resolve(app.get('appPath') + '/index.html'));
      });
}

在api

const express = require('express')
const router = express.Router()

router.use('/api/cpd', require('./cpd'));
router.use('/api/categories', require('./category'));
router.use('/api/terms', require('./term'));
router.use('/api/qae', require('./qae'));
router.use('/api/stats', require('./stat'));
router.use('/api/tags', require('./tag'));
router.use('/api/questions', require('./question'));
router.use('/api/things', require('./thing'));
router.use('/api/users', require('./user'));

module.exports = router

这样，您的所有api路由都将类似于/qae/api/*.如果在该前缀之后还需要auth，则需要使用相同的方法.最好的解决方案是让我app.use('/',...)包括子文件夹中的路由器.

That way all your api routes will look like /qae/api/*. If you need auth also after this prefix you need to do it same way.Best solution is to have i app.use('/',...) including routers from subfolders.
