nodejs版本：v4.4.3
开发工具：Sublime Text 3
创建一个名为app.js的空文件，添加以下代码：
//Lets require/import the HTTP module
var http = require('http');
//Lets define a port we want to listen to
const PORT = 1337;
//We need a function which handles requests and send response
function handleRequest(request, response) {
response.end('It Works!! Path Hit: ' + request.url);
}
//Create a server
var server = http.createServer(handleRequest);
//Lets start our server
server.listen(PORT, function() {
//Callback triggered when server is successfully listening. Hurray!
console.log("Server listening on: http://localhost:%s", PORT);
});
在终端里运行app.js，启动服务器：
liyorodeMacBook-Pro:nodejs liyoro$ node app.js
Server listening on: http://localhost:1337
浏览器里面打开http://localhost:1337，可以看到handleRequest里面设置的文字。
以上只是搭建了一个基本的http服务器，测试NSURLSession的GET、POST时，需要调度不同的页面（URL paths）、并且返回不同的数据进行测试，nodejs提供了Dispatcher模块来实现此需求。
安装httpdispatcher模块：
npm install httpdispatcher
如果很慢、甚至装不上，请用以下方式安装：
npm install httpdispatcher --registry=http://registry.npmjs.org
新增模块后的完整代码如下：
//Lets require/import the HTTP module
var http = require('http');
var dispatcher = require('httpdispatcher');
var url = require('url');
var util = require('util');
//Lets define a port we want to listen to
const PORT = 1337;
//We need a function which handles requests and send response
function handleRequest(request, response) {
// response.end('It Works!! Path Hit: ' + request.url);
try {
//log the request on console
console.log(request.url);
//Disptach
dispatcher.dispatch(request, response);
} catch(err) {
console.log(err);
}
}
//Create a server
var server = http.createServer(handleRequest);
//Lets start our server
server.listen(PORT, function() {
//Callback triggered when server is successfully listening. Hurray!
console.log("Server listening on: http://localhost:%s", PORT);
});
//For all your static (js/css/images/etc.) set the directory name (relative path).
dispatcher.setStatic('resources');
//A sample GET request
dispatcher.onGet("/page1", function(req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
// res.end('Page One');
res.end(util.inspect(url.parse(req.url, true).query))
// res.end(util.inspect(url.parse(req.url, true)));
});
//A sample POST request
dispatcher.onPost("/post1", function(req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Got Post Data');
});
测试GET、POST请求，使用 Postman
GET /page1 => 'Page One'
POST /post1 => 'Got Post Data'
