How to upload files (xlsx,txt,csv) using REST components for Zapi API

[_AnonymousUser]

Experts,
I need to upload files using Talend tREST component to Zephyr/JIRA. I do not know the format/syntax to give in httpbody section like the curl's ( -F "file=@myfile.txt" )

URL
 ?  
 entityId=4783&entityType=TestStepResult

BODY
 D:/TestResults/QPJ-707_Count_Mismatch.xls

I gave the full path and file name in body section. When I run, I am getting ERROR_CODE = 500.
Please help on how to give filepath/filename in the body section in tREST or any other REST components.
I do not get enough information in Zephyr/Zapi API website
Thanks,
Prakash.R
