Class Method Details

.convert_path(path) ⇒ Addressable::URI

Converts a path to a file scheme URI. If the path supplied is relative, it will be returned as a relative URI. If the path supplied is actually a non-file URI, it will parse the URI as if it had been parsed with Addressable::URI.parse. Handles all of the various Microsoft-specific formats for specifying paths.

Examples:

base = Addressable::URI.convert_path("/absolute/path/")
uri = Addressable::URI.convert_path("relative/path")
(base + uri).to_s
#=> "file:///absolute/path/relative/path"

Addressable::URI.convert_path(
  "c:\\windows\\My Documents 100%20\\foo.txt"
).to_s
#=> "file:///c:/windows/My%20Documents%20100%20/foo.txt"

Addressable::URI.convert_path("http://example.com/").to_s
#=> "http://example.com/"

Parameters:

  • path (String, Addressable::URI, #to_str) —

    Typically a String path to a file or directory, but will return a sensible return value if an absolute URI is supplied instead.

Returns:

  • (Addressable::URI) —

    The parsed file scheme URI or the original URI if some other URI scheme was provided.

.encode(uri, returning = String) ⇒ String, Addressable::URI Also known as: escape

Percent encodes any special characters in the URI.

Parameters:

  • uri (String, Addressable::URI, #to_str) —

    The URI to encode.

  • returning (Class) (defaults to: String) —

    The type of object to return. This value may only be set to String or Addressable::URI. All other values are invalid. Defaults to String.

Returns:

  • (String, Addressable::URI) —

    The encoded URI. The return type is determined by the returning parameter.

Returns:

  • (Array) —

    The decoded values. This is not a Hash because of the possibility for duplicate keys.

.heuristic_parse(uri, hints = {}) ⇒ Addressable::URI

Converts an input to a URI. The input does not have to be a valid URI — the method will use heuristics to guess what URI was intended. This is not standards-compliant, merely user-friendly.

Parameters:

  • uri (String, Addressable::URI, #to_str) —

    The URI string to parse. No parsing is performed if the object is already an Addressable::URI.

  • hints (Hash) (defaults to: {}) —

    A Hash of hints to the heuristic parser. Defaults to {:scheme => "http"}.

Returns:

end

.normalize_component(component, character_class = CharacterClasses::RESERVED + CharacterClasses::UNRESERVED) ⇒ String

Normalizes the encoding of a URI component.

'9' to be percent encoded. If a <code>Regexp</code> is passed, the
 value <code>/[^b-zB-Z0-9]/</code> would have the same effect. A set of
 useful <code>String</code> values may be found in the
 <code>Addressable::URI::CharacterClasses</code> module. The default
 value is the reserved plus unreserved character classes specified in
 <a href="http://www.ietf.org/rfc/rfc3986.txt">RFC 3986</a>.

Examples:

Addressable::URI.normalize_component("simpl%65/%65xampl%65", "b-zB-Z")
=> "simple%2Fex%61mple"
Addressable::URI.normalize_component(
  "simpl%65/%65xampl%65", /[^b-zB-Z]/
)
=> "simple%2Fex%61mple"
Addressable::URI.normalize_component(
  "simpl%65/%65xampl%65",
  Addressable::URI::CharacterClasses::UNRESERVED
)
=> "simple%2Fexample"

Parameters:

  • component (String, #to_str) —

    The URI component to encode.

  • character_class (String, Regexp) (defaults to: CharacterClasses::RESERVED + CharacterClasses::UNRESERVED) —

    The characters which are not percent encoded. If a String is passed, the String must be formatted as a regular expression character class. (Do not include the surrounding square brackets.) For example, "b-zB-Z0-9" would cause everything but the letters ‘b’ through ‘z’ and the numbers ‘0’ through

Returns:

  • (String) —

    The normalized component.

.normalized_encode(uri, returning = String) ⇒ String, Addressable::URI

Normalizes the encoding of a URI. Characters within a hostname are not percent encoded to allow for internationalized domain names.

Parameters:

  • uri (String, Addressable::URI, #to_str) —

    The URI to encode.

  • returning (Class) (defaults to: String) —

    The type of object to return. This value may only be set to String or Addressable::URI. All other values are invalid. Defaults to String.

Returns:

  • (String, Addressable::URI) —

    The encoded URI. The return type is determined by the returning parameter.

.unencode(uri, returning = String) ⇒ String, Addressable::URI Also known as: unescape, unencode_component, unescape_component

Unencodes any percent encoded characters within a URI component. This method may be used for unencoding either components or full URIs, however, it is recommended to use the unencode_component alias when unencoding components.

Parameters:

  • uri (String, Addressable::URI, #to_str) —

    The URI or component to unencode.

  • returning (Class) (defaults to: String) —

    The type of object to return. This value may only be set to String or Addressable::URI. All other values are invalid. Defaults to String.

Returns:

  • (String, Addressable::URI) —

    The unencoded component or URI. The return type is determined by the returning parameter.

Instance Method Details

#==(uri) ⇒ TrueClass, FalseClass

Parameters:

  • uri (Object) —

    The URI to compare.

Returns:

  • (TrueClass, FalseClass) —

    true if the URIs are equivalent, false otherwise.

  return self.normalize.to_s == uri.normalize.to_s
end

#===(uri) ⇒ TrueClass, FalseClass

Returns true if the URI objects are equal. This method normalizes both URIs before doing the comparison, and allows comparison against Strings.

Parameters:

  • uri (Object) —

    The URI to compare.

Returns:

  • (TrueClass, FalseClass) —

    true if the URIs are equivalent, false otherwise.

#query_values=(new_query_values) ⇒ Object

Sets the query component for this URI from a Hash object. This method produces a query string using the :subscript notation. An empty Hash will result in a nil query.

Parameters:

    The new query values.

Raises:

  • (TypeError)
