Custom Windchill ODATA implementation

hello Team,

I am implementing Rest service (GET )where i have to pass multiple oid of wtdocument  and user Id .

If user have access to that doc then  response will be  primary content Downloadable url.

It is working fine when i pass single OID.

How can we pass multiple oid in request ?

Any other approach I have to follow .Need Guidance to achieve this requirement.
