Finesse CORS enabling

[sghss214]

I am developing a custom UI for the finesse agent desktop. When I try to hit the finesse server from my domain(eg. localhost), the request does not happen and I receive No Transport error. I believe this is a CORS issue. I have 2 questions regarding this.

1. Could anything be done to enable CORS in Finesse server ?

2. Could "Access Control Allow Origin" be set to wildcard(*) in Finesse Response headers?

Hi,

CORS is supported starting Finesse 11.5. According to documentation,

In order to enable this support, Finesse expects them to send a specific header that contains the Origin Host name.

Header name: Origin.

The Host name value in Origin is used by Finesse to populate the Response Header named Access-Control-Allow-Origin.

Thanx,

Could you expand upon this dekwan?

So I am trying to do a ajax request to finesse / UCCX with the following code, according to my understanding of the document I add "Origin: mysite" to the request to allow cross origin. Though it is still being block. I am not the best at javascript. I can use a plugin that disables browser cross origin and mysite pulls the data and displays accurately.

  var ajax1 = $.ajax({
    cache: false,
    dataType: "json",
    Origin: http://myboard.mysite.com/
    url: "https://uccx.mysite.com:9443/realtime/VoiceCSQDetailsStats",
    async: true,
    success: function(result) {}
  });

CORS Support for Finesse REST API

If third-party web applications instantiated from a third-party web server need to make calls to Finesse Desktop APIs, they require Cross-Origin Resource Sharing (CORS) support. In order to enable this support, Finesse expects them to send a specific header that contains the Origin Host name.

Header name: Origin.

The Host name value in Origin is used by Finesse to populate the Response Header named Access-Control-Allow-Origin.

Note	When responding to a credentialed request, Finesse server must specify a domain and cannot use wild card characters, else the request will fail.

Hi,

For CORS, you need to send the Origin as a header of the REST API call. Your "Origin: http://myboard.mysite.com/" line is correct, BUT it is not formatted correctly in the context of your AJAX call.

Per stackoverflow discussion (https://stackoverflow.com/questions/7686827/how-can-i-add-a-custom-http-header-to-ajax-request-with-js-or-jquery/14655768#14655768), you need to do something like:

  var ajax1 = $.ajax({
    cache: false,
    dataType: "json",
    url: "https://uccx.mysite.com:9443/realtime/VoiceCSQDetailsStats",
    headers: { 'Origin': 'http://myboard.mysite.com' }
    async: true,
    success: function(result) {}
  });

Thanx,

(index):1 Access to XMLHttpRequest at 'https://uccxserver.domain.com:9443/realtime/VoiceCSQDetailsStats?_=1558730965750' from origin 'http://myotherserver.domain.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

This is what Chrome is spitting at me when in debug mode.

On UCCX I have added

The following origin(s) are configured in allowed origins:
1. http://myotherserver.domain.com

So I am just a little lost.

Hello Denise,
You said in this post CORS is supported starting from Finesse 11.5, According to documentation
We are using Finesse version 11.6 so ideally it would be supporting CORS, if we enabled it.
Bu we couldn't find any commands for enabling CORS in Cisco Finesse Admin guide 11.6 version, but those commands are available in 12.0(1) version.
We tried to enable it under impression that commands might be missed in 11.6 guide version, we got the commands from 12.0(1) and tried to implement in our 11.6 version but we didn't find any such commands.
So could you please help us on enabling CORS on our Finesse version 11.6

[dekwan]

Hi,

In 11.6, CORS should be automatically turned on. It was in 12.0 that a CLI was added to turn it on/off. Is it not working in 11.6? What error are you getting?

Thanx,

Denise

Hi,

We are still getting error back while we are requesting for Finesse APIs, Please find the error details below.

Attempt to set a forbidden header was denied: Origin

Cross-origin Request Blocked: The Same Origin policy disallows reading the remote resource at https://ourdomain.com:PortNumber/realtime/ChatQueueStatistics. (Reason: CORS request did not succeed)

Please find the screen shot attached and guide us to fix this issue.

Hi,

I'd suggest opening a support ticket because we'd probably need to look at logs and dive deeper to get to the root of the problem. You can open a ticket here: https://developer.cisco.com/site/support/

Thanx,

Denise
