NSURLSession之nodejs搭建简单http服务器

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'
