Parse Parse:

• Url.parse (urlstr[, parsequerystring][, Slashesdenotehost])

> Url.parse (' http://www.imooc.com/video/6710 ')

Build Item:
{protocol: ' http: ',
Slashes:true,
Auth:null,
Host: ' Www.imooc.com ',
Port:null,
Hostname: ' www.imooc.com ',
Hash:null,
Search:null,
Query:null,
Pathname: '/video/6710 ',
Path: '/video/6710 ',
HREF: ' http://www.imooc.com/video/6710 '}

Format parsing: The information you give generates a URL

• Url.format (Urlobj)

> Url.format ({protocol: ' http: ',
... slashes:true,
... auth:null,
... host: ' Www.imooc.com ',
... port:null,
... hostname: ' www.imooc.com ',
... hash:null,
... search:null,
... query:null,
... pathname: '/video/6710 ',
... path: '/video/6710 ',
... href: ' http://www.imooc.com/video/6710 '}
... )
Build item: ' http://www.imooc.com/video/6710 '

Resolve parsing

• Url.resolve (from, to)

> url.resolve (' http://imooc.com/', '/course/list ')
Build item: ' Http://imooc.com/course/list '
