I am using ucwa skype api. I have downloaded sample from ucwa.skype.com. while running the sample I need to login to my skype for business account. It gives me the below error.

回答1:

This issue (Service does not allow a cross domain request from this origin.) is mostly caused by the "Cross-Origin Resource Sharing (CORS)" and that the address which is requesting the access isn´t "whitelisted".

An Skype for Business Administrator can configure that via (more info's here):

$x = New-CsWebOrigin -Url "https://apps.contoso.com"
Set-CsWebServiceConfiguration -Identity "{YOUR_IDENTITY}" -CrossDomainAuthorizationList @{Add=$x}

before you change that, check if that is already done via:

Get-CsWebServiceConfiguration | select -ExpandProperty CrossDomainAuthorizationList

So that you will not overwrite something
