I want to call the API REST Confluence for my confluence server in Sharepoint's React.js code.
But I have this issue:
Access to XMLHttpRequest at 'http://confluence-server' from origin 'http://sharepoint2019' 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.
I already add http://sharepoint2019 in the whiteliste of my confluence server.
Thanks in advance
Thank you for reporting this to us. I'm aware of a bug where adding the URL to Allow Incoming in the Confluence whitelist isn't adding the necessary header.
There's a workaround on that bug where you can add the header yourself:
<!-- Tomcat built in CORS implementation --> <filter> <filter-name>CorsFilter</filter-name> <filter-class>org.apache.catalina.filters.CorsFilter</filter-class> </filter> <filter-mapping> <filter-name>CorsFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- End of built in CORS implementation -->
Header set Access-Control-Allow-Origin "*"
Can you try that, and let me know how it goes?
