HTTP access control #7

Closed Bvkb closed 7 years ago

Bvkb commented 7 years ago

Hi,

I'm testing TAME4 on different hardware/possibilities.

Connecting remotely to CX5130 / CX9020

Connecting TAME4 to ADS on CX9020 I run into the HTTP access control and pre-flight errors. On a CX5130 with windows embedded standard 7 you can add the needed headers into IIS and everything is running fine.

The CX9020 running windows embedded compact I see no possibility to add the needed headers somewhere. As I am not a javascript expert I had no luck trying xdomain or any proxy possibility to bypass this issue.

Do you see any resolution to this?

Great work!

Bryan

Sorry, I have no idea how to solve this. You could deactivate it in the browser.

I'm connecting to ADS on CX9020 with TAME4 and run into the message "Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

What I did to resolve it is to change the content of the webservice.js, for the "serviceUrl", use the IP address of the CX9020 instead of "localhost".

For example, mine is "http://192.168.1.25/TcAdsWebservice/TcAdsWebService.dll"
