uri_encoded/3

Description​

uri_encoded/3 is a predicate that unifies the given URI component with the given encoded or decoded string.

The signature is as follows:

uri_encoded(+Component, +Value, -Encoded) is det
uri_encoded(+Component, -Value, +Encoded) is det

Where:

  • Component represents the component of the URI to be escaped. It can be the atom 'query_path', 'fragment', 'path' or 'segment'.
  • Decoded represents the decoded string to be escaped.
  • Encoded represents the encoded string.

For more information on URI encoding, refer to RFC 3986.

Examples​

# Escape the given string to be used in the path component.
- uri_encoded(path, "foo/bar", Encoded).

# Unescape the given string to be used in the path component.
- uri_encoded(path, Decoded, foo%2Fbar).
