Experimental
Construct, validate, and parse URLs.
Globals
Constructors
URL(source, base)
The URL constructor creates an object that represents a URL, verifying that the provided string is a valid URL in the process. Any API in the SDK which has a URL parameter will accept URL objects, not raw strings, unless otherwise noted.
Parameters
source : string
A string to be converted into a URL. If source is not a valid URI, this constructor will throw an exception.
base : string
An optional string used to resolve relative source URLs into absolute ones.
DataURL(uri)
The DataURL constructor creates an object that represents a data: URL, verifying that the provided string is a valid data: URL in the process.
Parameters
uri : string
A string to be parsed as Data URL. If is not a valid URI, this constructor will throw an exception.
Functions
toFilename(url)
Attempts to convert the given URL to a native file path. This function will automatically attempt to resolve non-file protocols, such as the resource: protocol, to their place on the file system. An exception is raised if the URL can't be converted; otherwise, the native file path is returned as a string.
Parameters
url : string
The URL, as a string, to be converted.
Returns
string : The converted native file path as a string.
fromFilename(path)
Converts the given native file path to a file: URL.
Parameters
path : string
The native file path, as a string, to be converted.
Returns
string : The converted URL as a string.
isValidURI(uri)
Checks the validity of a URI. isValidURI("http://mozilla.org") would return true, whereas isValidURI("mozilla.org") would return false.
Parameters
uri : string
The URI, as a string, to be tested.
Returns
boolean : A boolean indicating whether or not the URI is valid.
getTLD(url)
Returns the top-level domain for the given URL: that is, the highest-level domain under which individual domains may be registered. Uses getPublicSuffix() internally.
var urls = require("sdk/url");
console.log(urls.getTLD("http://www.bbc.co.uk/")); // "co.uk"
console.log(urls.getTLD("https://developer.mozilla.org/")); // "org"
Parameters
url : string
The URL, as a string.
Returns
string : The top-level domain for the URL.
URL
Methods
toString()
Returns a string representation of the URL.
Returns
string : The URL as a string.
toJSON()
Returns a string representation of the URL.
Returns
string : The URL as a string.
Properties
scheme
The name of the protocol in the URL.
userPass
The username:password part of the URL, null if not present.
host
The host of the URL, null if not present. For example:
var url = require("sdk/url").URL("https://developer.mozilla.org/en-US/Add-ons");
console.log(url.host); // developer.mozilla.org
port
The port number of the URL, null if none was specified.
path
The path component of the URL. For example:
var url = require("sdk/url").URL("https://developer.mozilla.org/en-US/Add-ons");
console.log(url.path); // /en-US/Add-ons
hostname
The domain of the URL, as a string. Mirrors window.location.hostname.
pathname
An initial '/' followed by the path of the URL, as a string. Mirrors window.location.pathname.
hash
A '#' followed by the fragment identifier of the URL, as a string. Mirrors window.location.hash.
href
The whole URL as a string. Mirrors window.location.href.
origin
The canonical form of the origin for this URL, as a string. Mirrors window.location.origin.
protocol
The protocol scheme of the URL, including the final ':', as a string. Mirrors window.location.protocol.
search
If any parameters are present, a '?' followed by the parameters of the URL, as a string. Mirrors window.location.search.
DataURL
Methods
toString()
Returns a string representation of the Data URL. If base64 is true, the data property is encoded using base-64 encoding.
Returns
string : The URL as a string.
Properties
mimeType
The MIME type of the data. By default is an empty string.
parameters
An hashmap that contains the parameters of the Data URL. By default is an empty object.
base64
Defines the encoding for the value in data property.
data
The string that contains the data in the Data URL. If the uri given to the constructor contains base64 parameter, this string is decoded.
