URI Functions
Fields containing a Uniform Resource Identifier (URI) in string form can queried to extract the URI’s individual components of authority, fragment, host, path, port, query, scheme, schemeSpecificPart and userInfo. See either RFC 2306: Uniform Resource Identifiers (URI): Generic Syntax or Java’s java.net.URI Class for details regarding the components. If any component is not present within the passed URI, then an empty string is returned.
The extraction functions are
- extractAuthorityFromUri() - extract the Authority component
- extractFragmentFromUri() - extract the Fragment component
- extractHostFromUri() - extract the Host component
- extractPathFromUri() - extract the Path component
- extractPortFromUri() - extract the Port component
- extractQueryFromUri() - extract the Query component
- extractSchemeFromUri() - extract the Scheme component
- extractSchemeSpecificPartFromUri() - extract the Scheme specific part component
- extractUserInfoFromUri() - extract the UserInfo component
If the URI is http://foo:bar@w1.superman.com:8080/very/long/path.html?p1=v1&p2=v2#more-details the table below displays the extracted components
| Expression | Extraction |
|---|---|
| extractAuthorityFromUri(${URI}) | foo:bar@w1.superman.com:8080 |
| extractFragmentFromUri(${URI}) | more-details |
| extractHostFromUri(${URI}) | w1.superman.com |
| extractPathFromUri(${URI}) | /very/long/path.html |
| extractPortFromUri(${URI}) | 8080 |
| extractQueryFromUri(${URI}) | p1=v1&p2=v2 |
| extractSchemeFromUri(${URI}) | http |
| extractSchemeSpecificPartFromUri(${URI}) | //foo:bar@w1.superman.com:8080/very/long/path.html?p1=v1&p2=v2 |
| extractUserInfoFromUri(${URI}) | foo:bar |
