js url正则解析

1.正则

/^(?:(\w+):\/\/)?(?:(\w+):?(\w+)[email protected])?([^:\/\?#]+)(?::(\d+))?(\/[^\?#]+)?(?:\?([^#]+))?(?:#(\w+))?/

2.代码示例

var pattern = /^(?:(\w+):\/\/)?(?:(\w+):?(\w+)[email protected])?([^:\/\?#]+)(?::(\d+))?(\/[^\?#]+)?(?:\?([^#]+))?(?:#(\w+))?/;
var url = 'http://username:[email protected]:1234/artical/js/index.php?key1=js&key2=css#anchor';
var result = pattern.exec(url);

3.返回结果

数组类型 array
- arr[0] 源url
- arr[1] url的协议【http or https】
- arr[2] host中若包含key:value的形式的key，【通常没有为undefined】
- arr[3] host中若包含key:value的形式的value， 【通常没有为undefined】
- arr[4] host地址 【www.baidu.com or localhost or 192.168.0.1】
- arr[5] 端口号port 【8080 or 1234】
- arr[6] path值，接口地址【/api/v1/getData or /2017-10-27/store/pen.html】
- arr[7] url参数字符串 【name=jyjin&age=18】
- arr[8] hash路由，锚点。#号的值 【锚点id or 路由参数】

[
"http://username:[email protected]:1234/artical/js/index.php?key1=js&key2=css#anchor", 
"http", 
"username", 
"password", 
"www.bbs0101.com", 
"1234", 
"/artical/js/index.php", 
"key1=js&key2=css", 
"anchor", 
index: 0, 
input: "http://username:[email protected]:1234/artical/js/index.php?key1=js&key2=css#anchor"
]

4.封装使用

 * @return 模拟location对象
 * - href
 * - hash
 * - host
 * - hostname
 * - origin
 * - pathname
 * - prot
 * - protocol
 * - search
 * 
 * 源返回对象
 * - arr[0] 源url 
 * - arr[1] url的协议                              【http or https】 
 * - arr[2] host中若包含key：value的形式的key        【通常没有为undefined】 
 * - arr[3] host中若包含key：value的形式的value      【通常没有为undefined】 
 * - arr[4] host地址。                             【www.baidu.com or localhost or 192.168.0.1】 
 * - arr[5] 端口号port                             【8080 or 1234】

 * - arr[8] hash路由，锚点。#号的值.                 【锚点id or 路由参数】
