# RESTful
A RESTful web system build with node
### node获取url数据
官方API参考[node URL](http://nodeapi.ucdok.com/#/api/url.html)
/* 测试代码
* POST请求
var xmlhttp = new XMLHttpRequest();
var user = 'name=mohit&password=password4&profession=teacher&id=4';
xmlhttp.open('POST','http://localhost:8080/addUser',true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send(user);
* GET请求
var xmlhttp = new XMLHttpRequest();
// xmlhttp.open('GET','http://localhost:8080/listUsers');
xmlhttp.open('GET','http://localhost:8080/listUser/1');
xmlhttp.send();
* PUT请求
var xmlhttp = new XMLHttpRequest();
var user = 'name=mohit&password=password4&profession=teacher&id=4';
xmlhttp.open('PUT','http://localhost:8080/addUser/4',true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send(user);
* DELETE请求
var xmlhttp = new XMLHttpRequest();
xmlhttp.open('DELETE','http://localhost:8080/deleteUser/1');
xmlhttp.send();
*/
var http = require('http'),
fs = require('fs'),
url = require('url'),
querystring = require('querystring');
http.createServer(function (req, res) {
//获取请求方法
var method = req.method;
//获取原始请求路径
var path = req.url;
// 获取不带参数的路径
var pathname = url.parse(path).pathname;
// node path模块自带的pathname.split(path.sep)用于切割路径
// 但是由于windows和*nix下，具体看http://nodeapi.ucdok.com/#/api/path.html
// linux上的例子:'foo/bar/baz'.split(path.sep) returns ['foo', 'bar', 'baz']
// Windows上的例子:'foo\\bar\\baz'.split(path.sep) returns ['foo', 'bar', 'baz']
// 这里用pathname.split('/')来实现切割各个参数
pathname = pathname.split('/');
//获取GET/PUT/DELETE url传递的参数 通过来获取params.XXX
var params = url.parse(req.url).query;
params = querystring.parse(params);
//获取POST传递的参数 通过addListener来实现
var paramsPost ='';
req.addListener('data', function(chunk){
paramsPost += chunk;
})
.addListener('end', function(){
paramsPost = querystring.parse(paramsPost);
console.log(paramsPost);
});
}).listen(8080, '127.0.0.1');
console.log('Server running at http://127.0.0.1:8080/');

关于PUT和POST的差别，可以看看《HTTP权威指南》，里边提到的是
- PUT：“让服务器用请求的主体部分来创建一个由请求的URL命名的新文档，或者是替换指定URL的文档”
- POST：“post用于向服务器发送数据，而put用于向服务器上的资源中存储数据，通常POST方法用于HTML中的表单，用户在表单中填好数据之后，点击发送，填好的数据便会发送到服务器，然后由服务器将其送到它要去的地方(例如一个网关程序，然后由这个程序对数据进行处理)”
通过链接来看的话
- PUT：http://localhost:8080/addUser/1 body:'name=mohit&password=password4&profession=teacher&id=4'
- POST：http://localhost:8080/addUser body:'name=mohit&password=password4&profession=teacher&id=4'
在HTTP规范中对POST和PUT是这样定义的：
- The POST method isused to request that the origin server accept the entity enclosed in therequest as a new subordinate of the resource identified by the Request-URI inthe Request-Line ...... If a resource has been created on the origin server,the response SHOULD be 201 (Created) and contain an entity which describes thestatus of the request and refers to the new resource, and a Location header.
- The PUT methodrequests that the enclosed entity be stored under the supplied Request-URI. Ifthe Request-URI refers to an already existing resource, the enclosed entitySHOULD be considered as a modified version of the one residing on the originserver. If the Request-URI does not point to an existing resource, and that URIis capable of being defined as a new resource by the requesting user agent, theorigin server can create the resource with that URI.
大概意思就是，POST全部数据传到服务器处理，而PUT指定了URL上的资源进行操作，但是实际上，最大的差别不是在语义，而是在幂等和非幂等
