use of org.owasp.esapi.Validator in project OpenAM by OpenRock.

the class ConsumerRequest method postConsumerRegistrations.

/**
     * POST method for registering a Service Consumer
     * and obtaining corresponding consumer key & secret.
     *
     * @param formParams {@link String} containing the service 
     * consumer's description.
     * This description takes the form of name=value pairs separated by &.
     * The following parameters are supported:
     * <OL>
     * <LI>name - the service consumer's name.</LI>
     * <LI>icon - the service consumer's URI for its icon (MUST be unique).</LI>
     * <LI>service - the service consumer's URI for its service</LI>
     * <LI>rsapublickey - (optional) the RSA public key of the Service Consumer.</LI>
     * </OL>
     * <p>
     *
     * Example of string:
     * <pre>
     *  name=Service XYZ&icon=http://www.example.com/icon.jpg&service=http://www.example.com
     * </pre>
     *
     *
     * @return an HTTP response with content of the created resource.
     * The location URI is set to the newly created OAuth consumer key.
     * The body of the response is of the form:
     * <pre>
     * consumer_key=http://serviceprovider/0123456762121
     * consumer_secret=12345633
     * </pre>
     * Both values are URL encoded.
