对比spring,django，再学习express就有很多共通的地方啦。。。
看的书是一本小书，《express in action》，排版比较好。
昨天开始看，看了快四分之一啦。。。
练习代码：
var express = require("express");
var http = require("http");
var path = require("path");
var logger = require("morgan");
var app = express();
var publicPath = path.resolve(__dirname, "public");
app.set("views", path.resolve(__dirname, "views"));
app.set("view engine", "ejs");
app.use(express.static(publicPath));
app.use(logger("short"));
app.get("/", function(request, response) {
response.render("index", {
message: "Hey everyone! This is my webpage."
});
});
app.get("/about", function(request, response) {
response.end("Welcome to my aboutpage!");
});
app.get("/weather", function(request, response) {
response.end("The current weather is NICE!");
});
app.get("/user/:who", function(request, response) {
response.end("Hello, " + request.params.who + ".");
});
app.use(function(request, response) {
response.statusCode = 404;
response.end("404!");
});
http.createServer(app).listen(3000);
