parseGadgetSpecUrl

public PluginGadgetSpec.Key parseGadgetSpecUrl(String gadgetSpecUrl)

Parses a gadget spec URL in the format returned from #buildGadgetSpecUrl(String, String) into a PluginResourceKey containing the plugin key and resource location specified by the URL. The URL must contain the standard resource prefix, and both a plugin key and resource location in the path. It may contain a module key after the plugin key separated by a colon. If the URL is absolute, it must match the base URL for this application.

For example:

• Relative URL without module key: rest/gadgets/1.0/g/test.plugin/path/to/gadget.xml
• Absolute URL without module key: http://localhost:8080/dashboards/rest/gadgets/1.0/g/test.plugin/path/to/gadget.xml)
• Relative URL with module key: rest/gadgets/1.0/g/test.plugin:module-key/path/to/gadget.xml
• Absolute URL with module key: http://localhost:8080/dashboards/rest/gadgets/1.0/g/test.plugin:module-key/path/to/gadget.xml)

Parameters:

gadgetSpecUrl - a valid, URL-encoded gadget spec URL, as produced by #buildGadgetSpecUrl(String, String) or #buildGadgetSpecUrl(com.atlassian.gadgets.plugins.PluginGadgetSpec.Key). May be absolute, if the base URL matches the base URL retrieved from the ApplicationProperties instance this GadgetSpecUrlBuilder was initialized with. Must not be null, or a NullPointerException will be thrown.

Returns:

a PluginResourceKey built from the plugin key and resource location parsed and decoded from the URL

Throws:

GadgetSpecUriNotAllowedException - if the URL does not start with the prefix for gadget specs published from this application, or if either the plugin key or resource location is missing or blank

NullPointerException - if gadgetSpecUrl is null
