URL with = character should use numbered parameters
If the URL contains an equals sign, as is common in a query string, the parameter |1= should be used for the URL ({{URL|1=example.com}}). This applies when the value of the URL is unknown, for example, when this template is used in another template specifying the effective URL as a variable value
The template attempts to handle simple cases where a URL containing an equals sign is specified without the necessary |1=, but it is still better practice to pass it in.
The deprecated second parameter for the displayed text, if present in legacy uses, must also be explicitly numbered if the first parameter is explicitly numbered ({{URL|1=url name|2=optional display text}}); otherwise it will override the value of the first parameter:
Examples
The template displays an instructional message if there is no input:
{{URL| }} → {{URL|example.com|optional display text}}
The template wraps the output in <span class="url">...</span> (see § Microformat) and adds <wbr/> before displayed periods:
The use of http://, https://, a protocol-relative URL, or a different protocol is preserved in the URL but is not shown in the link text:
If the path is only a slash (/) it is not displayed in the link text:
The template also adds <wbr/> before any displayed slashes (/) in the path:
Upper case in the domain name is preserved in the URL, but not in the link text (upper case in the path is not changed):
For a URL containing an equal sign (=), use |1=:
The template currently supports an optional second parameter which is used as the link text, though its use is discouraged (see note):
The URL may be obtained from Wikidata as shown in this example for Audi AG (Q23317), where the property official website (P856) contains https://www.audi.com:
