Nodejs URL Detailed

1 We can use the . Parse method to convert a URL string to a URL object

For example:

Url.parse (' Http://user:[email protected]:8080/p/a/t/h?query=string#hash ');
/* =
{protocol: ' http: ',
Auth: ' User:pass ',
Host: ' host.com:8080 ',
Port: ' 8080 ',
Hostname: ' host.com ',
Hash: ' #hash ',
Search: '? query=string ',
Query: ' query=string ',
Pathname: '/p/a/t/h ',
Path: '/p/a/t/h?query=string ',
HREF: ' Http://user:[email protected]:8080/p/a/t/h?query=string#hash '}
*/

Url.parse (Urlstr, [parsequerystring], [Slashesdenotehost])

Receive parameters:

Urlstr URL string

When parsequerystring is true, query strings are parsed using the query module, which defaults to False

Slashesdenotehost

A string that defaults to False,//foo/bar form will be interpreted as {pathname: '//foo/bar '}

If the string is set to True,//foo/bar form, it will be interpreted as {host: ' foo ', pathname: '/bar '}

Example:

var url = require (' URL ');
var a = Url.parse (' http://example.com:8080/one?a= Index&t=article&m=default ');
Console.log (a);
 
//output:
{
    protocol: ' http ',
    auth:null,
 &N bsp;  host: ' example.com:8080 ',
    port: ' 8080 ',
    hostname: ' example.c Om ',
    hash:null,
    search: '? A=index&t=article&m=default ',
&N bsp;   query: ' A=index&t=article&m=default ',
    pathname: '/one ',
 & nbsp;  path: '/one?a=index&t=article&m=default ',
    href: ' http://example.com:8080 /one?a=index&t=article&m=default '
}

If parsequerystring is set to true , query in the URL object becomes an object, such as: Query:{a: "Index", T:: "article", M: "Default"}

2 . Resolve method can be used for stitching URLs

Url.resolve (' Http://www.example.com/foo/bar ', ' ... /baz ');
/* =

Http://www.example.com/baz

*/

3 in turn, the. Format method allows you to convert a URL object to a URL string

Url.format ({
Protocol: ' http: ',
Host: ' www.example.com ',
Pathname: '/p/a/t/h ',
Search: ' query=string '
});
/* =
' Http://www.example.com/p/a/t/h?query=string '
*/

URL parameter Description :

{

Protocol: ' http: ', Slashes:true, Auth:null, Host: ' localhost:8888 ', Port: ' 8888 ', hostname: ' Localho St ', Hash:null, search: '? Name=bigbear&memo=helloworld ', query: ' Name=bigbear&memo=helloworld ', p Athname: '/bb ', path: '/bb?name=bigbear&memo=helloworld ', href: ' Http://localhost:8888/bb?name=bigbear&mem O=helloworld '} protocol: the request protocol Host:url hostname has all been converted to lowercase, including the port information Auth:url the authentication Information section hostname: Host name part, converted to lowercase port: primary 　　The port number section of the machine Pathname:url the path portion of the query string section before requesting the query after the hostname, including the question mark at the beginning of the Search:url. 　　Path:pathname and search are linked together. 　　Query: The parameter part of the queried string (the string after the question mark), or the object returned after parsing with Querystring.parse (). Hash:url "#" after section (including # symbol)
