(回调函数)关于express中post方法的回调函数

app.post 在这里：

http://expressjs.com/api.html

app.METHOD(path, callback [, callback ...]) Routes an HTTP request, where METHOD is the HTTP method of the request, such as GET, PUT, POST, and so on, in lowercase. Thus, the actual methods are app.get(), app.post(), app.put(), and so on. See below for the complete list.

请求的解析这里有讲：

http://expressjs.com/guide/routing.html

// respond with "hello world" when a GET request is made to the homepage
app.get('/', function(req, res) {
  res.send('hello world');
});
