Deeplink login

[Janssenjos]

Hi,

We want to use the deeplinking to login in servoy.
Our setup is as followed, we deeplink to a global solution which calls our login method. But after a succesfull login, our custom login page is showed instead of the default form.

Is there something were doing wrong?

(See the attachment for our sample solution)

Make sure security.login() parameters are valid (check that uid and username are not null).

When those are ok then you are probably running into a problem that is fixed in future builds - the security.login(...) calls your method loginmethod(...) that calls back the security.login(...) and so on.
The workaround would be to make sure loginmethod(...) calls are not overlapping. Something like:

Code: Select all

var inside = 0;

function loginmethod( usr,  pwd)
{
   if (inside == 1) return;
   inside = 1;
   
   try {
      (... method code ...)
   } finally {
      inside = 0;
   }
}

Thanks for your answer.

I tried your solution, but it still isn't working correctly.

It seems that cause the solution is set to mustAuthenticate, the function in the deeplink isn't called. But instead you get the login screen, cause you need to login(mustAuthenticate).
When I log in and then try the deeplink login again, it works.

So is there a solution or workaround for this, so we can make a deeplink login? (I don't want to disable mustAuthenticate)

What version of Servoy do you use?

[Harjo]

yeah, we filed a case a long time ago about this.

this is the response we got from Andrei:

When you check the "Solution needs login" (and specify a login form or not), the global method specified in the deeplink will only execute after the login has been performed. So after the "security.login(...)" function is called in case you have a login form, the global method from the link will execute. This does work from what I tested. Executing methods from URL before login would be a security risk - as anyone would be able to execute any of the global methods without logging in, just by using an URL.

[Janssenjos]

Ok, so as I understand, there is just no way to have a external login page then?

[Andrei Costescu]

(...)this is the response we got from Andrei:(...)

I already forgot about that . Yes, you are both right, you can't do that as it would mean anyone could call any of your global methods.
I just tested a bit before and it worked because I was using the same browser session where I was logged in earlier...

Ok, so as I understand, there is just no way to have a external login page then?

what we could try to do in a next version of servoy is that you can give arguments to the onload/onshow method of a the Login form.
So that when some identifier is given to that onload/onshow method you can test this and do the logon directly through your login form. (not even really showing it)

you could make a case for this if you would like something like that.

You can already deeplink into a solution and perform automatic login, just not using a method.

Just specify extra parameters on the url and in the onLoad of your login form check the startup arguments (application.getStartupArguments()) and if you receive the proper arguments (whatever you determine) log the user in and automatically the onsolutionstart method will fire and the first form will be shown.

See http://wiki.servoy.com/display/DOCS/Smart+Client and http://wiki.servoy.com/display/DOCS/Web+Client for the options to specify arguments on the url's

Paul is this really true?

we checked this before, if you specify a global method with arguments, the method with arguments are only fired, when you are (already) logged in

[pbakker]

Ofcourse it's true or else I wouldn't be saying it!

But, you haven't read what I said. I said "not with a method"

Big difference...

Paul

[Harjo]

ah oke, thanks for pointing that out!

[mboegem]

I said "not with a method"

We use a deeplink to pass credentials, but at the time building this I found that I couldn't pass arguments without at least specify a global method in my deeplink as well.
To workaround this, I just created an empty global method 'login' which does nothing (as it's empty )

The handling of the arguments is as Paul pointed out from the 'onLoad' on the loginform.

This really helped out, thanks.

Can anyone help me how to go about this? I am doing a deeplink login as well to automate the process inside the solution. Would the onLoad method of the login form require argument[0] to be of type JSEvent? How will the arguments be read?
