Issue in passing Session values in .body(RawFileBody("A"))

[Silent Streamer10]

Hi All,

I am using the Gatling 3.5.1 versions and observed the following.

1. I am posting a multipart form data request in Raw format to the server and when I enabled the log file, it is sent in Base64 format from Gatling. When I decoded it via base64 decoder online , I could see that the  Correlated session values are not substituted  and it is simply sent as such. 

2. When I tried to the do the same as above by importing this import io.gatling.core.body.RawFileBody  , I am getting this error Can't cast of type class java.lang.String into class io.gatling.core.body.ResourceAndCachedBytes.

Note: The substitution works fine with ElFilebody and StringBody but the server couldn't accept those format.

Kindly Help on this.

Regards,

Aravind G

Hi,

No idea what you're doing.

Please share some code, stacktraces, etc...

OK, you're trying to do `body(new RawFileBody(???))` while the documentation clearly states `body(RawFileBody(???))` without the `new`.

Hi Stephane,

Thanks for the reply.

No, I am using only the .body(RawFileBody("??")).

Please find the detailed observation below with the code trace

1. Scenario 1 ( Without import io.gatling.core.body.RawFileBody ) - Substitution of session values  not happening

object A {

    // First call from where I get the dynamic values and correlate it in the xml file given in request-bodies/xml

        .exec(http("A")

          .post(url + "/B")

          .headers(C)

          .body(RawFileBody("request-bodies/xml"))

          .check(status.is(200)))

}

2. Scenario 2 ( With  import io.gatling.core.body.RawFileBody )  ( rest of the code trace remains the same) 

Result - Unable to trigger the second request and getting the error Can't cast of type class java.lang.String into class io.gatling.core.body.ResourceAndCachedBytes.

I hope this will be helpful Stephane. 

Note: The substitution works fine with ElFilebody and StringBody but the server couldn't accept those format

The whole point of RawFileBody is to be able to send a file as is, without any transformation. So it doesn't support EL expressions.

Hi Stephane,

Thanks for the clarification. I thought of an workaround to replace the correlated values in the request file and replace it with the dynamic values by using some file operations before triggering the actual request.
