Hi everybody,

I would like to use the ELFileBody function of gatling to post dynamic parameters for a specific request.

My request is very simple, just the creation of a new events on a JSON Calendar. But i don’t want to always create the same event.

Is that possible to have dynamic params. I’ve read about it but i don’t really understand how it works with scala.

**Here is the scala code**

//Validation Form New Event Agenda  
.resources(http(“Validation Form Nouveau RDV I Agenda”)  
.post(uri1 + “/agenda/ideoFront?controller=rdv.Rdv&webContext=%7B%22clePatien…”)  
.headers(headers\_6)  
.body(RawFileBody(“request14.txt”))))

**Here is the request14.txt body**

{

“dateDebut”:“2016-07-20T10:30:00Z”,  
“professionnelList”:[],  
“patientList”:[{“id”:“PAT;LOC;1.2.250.1.192.7.1.18;196”,“debut”:0,“duree”:1800}],

}

Thanks a lot for your help,
