recaptcha works with click

[Andrei <gm...@gmail.com>]

I created this simple class and tried - it works fine with captcha
http://www.google.com/recaptcha

package com.andreig.hiredonphone;
import org.apache.click.control.AbstractControl;

public class ReCaptchaField extends AbstractControl {

   private String value;
   private String public_key;

   // -------------------------------
   public ReCaptchaField( String public_key ){
     this.public_key = public_key;
     setName( "captcha" );
   }

   // -------------------------------
   public void setValue(String value) {
       this.value = value;
   }

   // -------------------------------
   public String getValue() {
       return value;
   }

   // -------------------------------
   public String getTag() {
       // Return the HTML tag
       return "br/><i>To verify that you are human</i><br/>" +
	 "<script type=\"text/javascript\"
src=\"http://api.recaptcha.net/challenge?k=" +
	 public_key +
	 "\"></script><noscript><iframe src=\"http://api.recaptcha.net/noscript?k=" +
	 public_key +
	 "\" height=\"300\" width=\"500\"
frameborder=\"0\"></iframe><br></noscript><br";
   }

   // -------------------------------
   public boolean onProcess() {
       // Bind the request parameter to the field value
       String requestValue = getContext().getRequestParameter(getName());
       setValue(requestValue);

       // Invoke any listener of MyField
       return true;
   }

 }


You use it as this, put your public key in constructor

    ReCaptchaField captcha = new ReCaptchaField(
"6LfTf7sSAAAAAICJsZlojJaUAJX1Cws-aEBMm7oJ" );
    form.add( captcha );


Then in "onSubmit" I put


    HttpServletRequest request = getContext().getRequest();

    String remoteAddr = request.getRemoteAddr();
    ReCaptchaImpl reCaptcha = new ReCaptchaImpl();
    reCaptcha.setPrivateKey( "my_private_key" );

    String challenge = request.getParameter("recaptcha_challenge_field");
    String uresponse = request.getParameter("recaptcha_response_field");
    ReCaptchaResponse reCaptchaResponse =
reCaptcha.checkAnswer(remoteAddr, challenge, uresponse);

    if( !reCaptchaResponse.isValid() ){
      msg = "Captcha field not correct";
      return false;
    }

Not related to captcha and this class, just inspired idea:

@Click developers:


May be add one method in Page class for this (some copy-paste from Spring):

/**
	 * Process the specified template with the given model and write
	 * the result to the given Writer.
	 * <p>When using this method to prepare a text for a mail to be sent with
Spring's
	 * mail support, consider wrapping IO/TemplateException in
MailPreparationException.
	 * @param model the model object, typically a Map that contains model names
	 * as keys and model objects as values
	 * @return the result as String
	 * @throws IOException if the template wasn't found or couldn't be read
	 * @throws TemplateException if rendering failed
	 */
public String template (String templatePath, Map<String, ?> model) throws
IOException, TemplateException {

// Get the template object
        Template template = configuration.getTemplate(templatePath);
	StringWriter writer = new StringWriter();

       
        try { // Merge the data-model and the template
            template.process(model, writer);

        } catch (freemarker.template.TemplateException fmte) {
            throw new TemplateException(fmte);
        }

	return result.toString();
}//template

and also good idea to add handy functions from Google Guava to ClickUtils:
public static <K, V> Map<K, V> mapOf (final K k, final V v) {
    final Map<K, V> map = new LinkedHashMap<K, V>();
    map.put(k, v);
    return map;
  }//mapOf


  public static <K, V> Map<K, V> mapOf (final K k1, final V v1, final K k2,
final V v2) {
    final Map<K, V> map = new LinkedHashMap<K, V>();
    map.put(k1, v1);
    map.put(k2, v2);
    return map;
  }//mapOf


  public static <K, V> Map<K, V> mapOf (final K k1, final V v1, final K k2,
final V v2, final K k3, final V v3) {
    final Map<K, V> map = new LinkedHashMap<K, V>();
    map.put(k1, v1);
    map.put(k2, v2);
    map.put(k3, v3);
    return map;
  }//mapOf


then you can make above code easy
return template("/com/andreig/hiredonphone/cap.ftl_or_vm",
mapOf("public_key", public_key);

Template in external file (not in java String) is good think: IDE can
highlight and verify it.

Only one problem here: Freemarker/Velocity binding (if you change template
engine code stop working).

But there is my comment in JIRA with idea how to solve it:
https://issues.apache.org/jira/browse/CLK-364?focusedCommentId=12801392&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12801392


PS: just my fast brain dump (so sorry for usual bad English)
