options for isURL method
|
|
|
|
protocols - valid protocols can be modified with this option.
|
|
require_tld - If set to false isURL will not check if the URL's host includes a top-level domain.
|
|
require_protocol - if set to true isURL will return false if protocol is not present in the URL.
|
|
require_host - if set to false isURL will not check if host is present in the URL.
|
|
require_port - if set to true isURL will check if port is present in the URL.
|
|
require_valid_protocol - isURL will check if the URL's protocol is present in the protocols option.
|
|
allow_underscores - if set to true, the validator will allow underscores in the URL.
|
|
host_whitelist - if set to an array of strings or regexp, and the domain matches none of the strings
|
|
defined in it, the validation fails.
|
|
host_blacklist - if set to an array of strings or regexp, and the domain matches any of the strings
|
|
defined in it, the validation fails.
|
|
allow_trailing_dot - if set to true, the validator will allow the domain to end with
|
|
a `.` character.
|
|
allow_protocol_relative_urls - if set to true protocol relative URLs will be allowed.
|
|
allow_fragments - if set to false isURL will return false if fragments are present.
|
|
allow_query_components - if set to false isURL will return false if query components are present.
|
|
disallow_auth - if set to true, the validator will fail if the URL contains an authentication
|
|
component, e.g. `http://username:password@example.com`
|
|
validate_length - if set to false isURL will skip string length validation. `max_allowed_length`
|
|
will be ignored if this is set as `false`.
|
|
max_allowed_length - if set, isURL will not allow URLs longer than the specified value (default is
|
|
2084 that IE maximum URL length).
