Access validation methods

Question

Hi there,

I am currently implementing the GUI for user registration. Here, I'd like to display some custom messages to the user, if there is a validation problem. Unfortunately, I could not find any way t access the App42's validation methods. Also, the exceptions thrown at e.g. invalid e-mail address seem to not contain any error codes.

Is there a way to access those validation methods or what is common practice here?

 

Thanks in advance,

flogy

Hello, 

Please find a below code snippet and add this method in your app and call this method before making a call to App42 Server:

public boolean isValidEmail(String checkString) {

Pattern p = Pattern.compile("^[\\w\\]([\\.\\w])+[\\w]+@([\\w\\]+\\.)+[A-Z]{2,4}$", Pattern.CASE_INSENSITIVE);

Matcher m = p.matcher(checkString);

boolean b = m.matches();
if (b != true)

   return false;

 

return true;

}

 

Let us know if it helps.

Hello,
thanks for your reply. I will go by calling the Util.throwExceptionIfEmailNotValid(...) method then (seems to be the code you have posted).

These validations are checked at client side and does not have any error codes.  These validations include null, blank or invalid value of parameters. You can simply catch these App42Exception and can check for error message to handle it.

Let me know if it helps.

Thanks for your quick answer. I see, but I'd like to avoid parsing the error messages to determine, what the problem might be... That's why I asked about the error codes.
Is there no public API to call those validation methods directly? Something like ValidationUtil.isUserNameValid(String userName)?
Thanks

Which SDK you are using? I will give you util method name for the same.
