[uniGUI Pro 1.95.0.1595] An Exception has occured in application: Failed to initialize node: 2

[bruno65]

i added another application in the hyper_server.cfg file :

[application-0]
enabled=1
alias=other
binary_name=mySecondApp.exe
max_nodes=10
persistent_node=0

[hyper_server]
binary_name=myApp.exe
initial_nodes=2
max_nodes=10
max_sessions=0
sessions_per_nodes=0
prompt_login=0
persistent_node_zero=0
port=8077
...

in the hyper_server log file i've got :

So what's wrong in the configuration file or elsewhere ?

Hi

Make sure second app exe is a valid unigui application.

[bruno65]

ok Frashad,

i don't know if i must use "http://localhost/mywebapps/hyper_server.dll/other" or "http://localhost/mywebapps/other/hyper_server.dll" to reach the second webapp. Which is the right way to go ?

[Farshad Mohajeri]

http://localhost/mywebapps/hyper_server.dll/other

[bruno65]

i found it : http://localhost/mywebapps/hyper_server.dll/other is the right way.

Last question : how can i get the url above with code ?

uniSession.URL gives http://localhost/mywebapps/hyper_server.dll

the alias /other is not included. Why ?

[Farshad Mohajeri]

You can also use:

UniSession.UrlReferer

[bruno65]

i log Unisession.UrlReferer in the procedure TUniMainModule.UniGUIMainModuleBeforeLogin(Sender: TObject; var Handled: Boolean); but its value is empty.

i need to get the url (with the alias) from that event handler because i'll make a POST request to keycloak from here

[Farshad Mohajeri]

You can try:

UniSession.ARequest.Referer:

[bruno65]

i get the alias /other with ARequestInfo.URI in the procedure TUniServerModule.UniGUIServerModuleHTTPCommand(ARequestInfo: TIdHTTPRequestInfo;
  AResponseInfo: TIdHTTPResponseInfo; var Handled: Boolean);

[Farshad Mohajeri]

Another method:

UniServerModule.App;

Great Farshad ! Thank you
