Passing control to another unigui application and go back

[gesulmino]

Hi,

From a unigui application (WebA) I should post some data to a url, another unigui application (WebB). WebB shows a form to ask some additional information to the user depending from url parameters, then returns control to the calling session in WebA indicating some return parameters. I hope I was clear.

Any suggestions or examples on this?

Hi

Please check " HTTP Post Callback - URLFrame - Auto Target" demo

Key point is

Sc:=UniSession.CallbackUrlEx('mycallback', Self, ['RES', 'OK']);
S:=StringReplace(S, '{URL_CALLBACK}', Sc, []);

I tried this,

s := 'var f = document.createElement("form"); '+
    'f.action="'+UniServerModule.PIN_EndPoint+'/login"; '+ // the second app url
    'f.method="POST"; ';

  aUrl := UniSession.CallbackUrlEx('mycallback', Self, ['RES', 'OK'], true, false);

  s := s+
    'var i=document.createElement("input"); '+ // url_submit
    'i.type="hidden"; '+
    'i.name="url_submit"; '+
    'i.value="'+TNetEncoding.Url.Encode(Base64Encode(aUrl))+'"; '+
    'f.appendChild(i); ';

  aUrl := UniSession.CallbackUrlEx('mycallback', Self, ['RES', 'CANCEL'], true, false);

  s := s+
    'var i2=document.createElement("input"); '+ // url_cancel
    'i2.type="hidden"; '+
    'i2.name="url_cancel"; '+
    'i2.value="'+TNetEncoding.Url.Encode(Base64Encode(aUrl))+'"; '+
    'f.appendChild(i2); '+

    'document.body.appendChild(f); '+
    'f.submit(); ';

  UniSession.AddJS(s)

 

this show a form with some fields

but I obtain this result when I submit the form

http://localhost:8080/integra/HandleEvent?IsEvent=1&Obj=O0&Ajax=1&Evt=mycallback&RES=OK&_S_ID=5icJiog4CK1042A9E43&__EXCB__=1

Invalid session or session Timeout.

Restart application

what is wrong?
