Mobile app call to Rollbase Private Cloud REST service encountering CORS error

This question is not answered

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://xxx.xxxx.com/rest/mobile/api/static/home.html. This can be fixed by moving the resource to the same domain or enabling CORS.

Above is the error I get if I run a mobile app generated via the mobile app development in our Private Cloud (the same one as what the call is made to) but if I host the mobile app files on a different domain.  Makes sense this could be an issue but I see the CORS configuration in the private clouds REST web.xml:

        <filter>
        <filter-name>CORSFilter</filter-name>
        <filter-class>com.rb.rest.logics.filter.CORSFilter</filter-class>
        </filter>
        <filter-mapping>
        <filter-name>CORSFilter</filter-name>
        <url-pattern>/mobile/*</url-pattern>
        </filter-mapping>

Also I have put the following in the private cloud's Tomcat web.xml:

<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>

Still getting the CORS error, any suggestions on what's missing?

  • Hi ,

      In Rollbase Private cloud instance, If the mobile app files are hosted in a different domain then you need to add the CORS regluar expression in shared.properties

    RBMobile_CORS.Allow_origin.HOST = %RBMobileCORSOriginRegx%

    RBMobileCORSOriginRegx value should be a regular expression that matches the Origin of the header of the request.

    Example: If the Mobile app is hosted on abc.test.com domain, then RBMobileCORSOriginRegx should be like .*test\\.abc\\.com$

    Hope this helps you.
