From the response there will be a fileurl
http://<yourmoodlesite>/webservice/pluginfile.php/14598/mod_resource/content/7/HLR%20ppt.htm?forcedownload=1
You can download the file with token like this
http://<yourmoodlesite>/webservice/pluginfile.php/14598/mod_resource/content/7/HLR%20ppt.htm?forcedownload=1&token=<yourtoken>
and you can display after downloading the content.
If any another solution you will find please share it with me.
Thanks
