Can not use RESTFUL call in login form

[stevewong]

Hi,

I was going to make a sign in with google button to my login form. I then get into trouble. My problem is : I was not able to issue RESTFUL call under windows IIS hyper server environment.

I have attached my code, it is a copy from the demo login form, when the user click login, it will do a REST request to a website to get something. The program work perfectly OK when I run it as a standalone exe. But when I deploy is to the hyper server, the program got an exception :

Signin_App.exe: 00001530: 10:26:48 [TUniServerModule]:Server First Init.

Can anyone help me to solve this ?

I have no problem running it on our HyperServer on IIS. So probably something in your environment?

I finally figured it out ! To make a RESTFUL call, you need to use the component NetHTTPClient.

In order to use TNetHttpCleint under IIS ISAPI environment, you need to do the following :

Under Application Pool -> your application -> Advance Setting -> Process Mode -> Identity -> Built in Account -> Network service

Then under the web application's Authentication Setting -> make Application Pool identity the default option. (using specific user : IUSR will cause cause an exception whenever you call TnetHttpClient.create)

I don't know why, but I hope this information helps.
