node.js - 用node express创建的默认应用，不能通过浏览器访问？

Question

按照github上的quick start一步一步下来，npm start 启动server， 但app.js貌似没有监听任何端口，但是server启动了？通过浏览器访问不了页面，是这样吗？

究竟是哪里有问题？

创建方法就是：

$ express /tmp/foo && cd /tmp/foo

启动服务器是:

$ npm install
$ npm start

更：

正如一楼说的，默认的是3000端口，写在bin/www里，但问题是这里明明debug出了文本，为什么终端窗口里看不到？

var server = app.listen(app.get('port'), function() {
  debug('Express server listening on port ' + server.address().port);
});

Answer 1

The listening port of express is set in the /bin/www.js file, and the default is port 3000. Do you have a port added to your browser?

Answer 2

Looking at the project generated by express, /bin/wwwrequired the https://github.com/visionmedia/debug module.

The DEBUG environment variable is then used to enable these based on space or comma-delimited names.

You can see all debug information like this:

DEBUG=* npm start

Of course there is also the sentence you expect to see: Express server listening on port 3000

Answer 3

Listening 0.0.0.0
