Example 1 with ScriptEngine

use of javax.script.ScriptEngine in project cas by apereo.

the class ScriptedRegisteredServiceAttributeReleasePolicy method getAttributesInternal.

@Override
protected Map<String, Object> getAttributesInternal(final Map<String, Object> attributes, final RegisteredService service) {
    try {
        String engineName = null;
        if (this.scriptFile.endsWith(".py")) {
            engineName = "python";
        } else if (this.scriptFile.endsWith(".js")) {
            engineName = "js";
        } else if (this.scriptFile.endsWith(".groovy")) {
            engineName = "groovy";
        }
        final ScriptEngine engine = new ScriptEngineManager().getEngineByName("python");
        if (engine == null || StringUtils.isBlank(engineName)) {
            LOGGER.warn("Script engine is not available for [{}]", engineName);
        } else {
            final File theScriptFile = ResourceUtils.getResourceFrom(this.scriptFile).getFile();
            if (theScriptFile.exists()) {
                LOGGER.debug("Created python object instance from class [{}]", theScriptFile.getCanonicalPath());
                final Object[] args = { attributes, LOGGER };
                LOGGER.debug("Executing python script's run method, with parameters [{}]", args);
                engine.eval(new FileReader(theScriptFile));
                final Invocable invocable = (Invocable) engine;
                final Map<String, Object> personAttributesMap = (Map<String, Object>) invocable.invokeFunction("run", args);
                LOGGER.debug("Final set of attributes determined by the script are [{}]", personAttributesMap);
                return personAttributesMap;
            }
            LOGGER.warn("Python script [{}] does not exist, or cannot be loaded", scriptFile);
        }
    } catch (final Exception e) {
        LOGGER.error(e.getMessage(), e);
