My gatling script creates a set of users (5) and then each user iterates over a loop 20 times. The contents of the loop issues a single http request. The http request is a POST request to a rest web service. I have a directory with 1000 request bodies. How do I grab one of those files to post (e.g. the parameter to the fileBody() method call)? I’ve tried the following using feed(), but it just tries to load a file that that includes the expression literally (not replacing it with a value from the csv file) – e.g. [http://myhost.mycompany.com:8080/my-rest-service](http://myhost.mycompany.com:8080/my-rest-service) My csv file listing all my data files looks like this: filename file123.txt file456.txt Essentially, I do three things: - load the csv file with the list of all my files containing http post contents: - val fileList = csv(“file\_listing\_\_separated\_smaller.csv”).concurrentQueue- call feed() with this fileList variable as a parameter - .feed(fileList)- call the fileBody() method - .fileBody("${filename}") Attempted script contents: val httpConf = httpConfig .baseURL(“[http://myhost.mycompany.com:8080](http://myhost.mycompany.com:8080)”) .acceptHeader("_/_") .userAgentHeader(“curl/7.21.4 (universal-apple-darwin11.0) libcurl/7.21.4 OpenSSL/0.9.8r zlib/1.2.5”) .warmUp(“[http://myhost.mycompany.com:8080](http://myhost.mycompany.com:8080)”) val headers\_1 = Map( “Content-Type” → “”“text/plain”"", “Expect” → “”“100-continue”"", “Proxy-Connection” → “”“Keep-Alive”"" ) val fileList = csv(“file\_listing.csv”).concurrentQueue val scn = scenario(“Scenario Name”) .feed(fileList) .repeat(20) { exec( http(“request\_1”) .post("/my-rest-service") .headers(headers\_1) .fileBody("${filename}") ) .pause(3) } setUp(scn.users(5).protocolConfig(httpConf)) Thanks!

Hi, Bad luck: that’s not currently possible, the template location is static. Could you fill an issue, please? We should be able to have it for 1.4.3 coming next week. Cheers, Stéphane ---

I actually implemented it on the master/v2 branch. This part has gone under major refactoring, so backporting is not straightforward. Would it be possible for you to use a 2.0.0-SNAPSHOT? You can grab one on Cloudbees: [https://forge.cloudbees.com/a/gatling/](https://forge.cloudbees.com/a/gatling/) Available methods are now: - body for passing a String - rawFileBody - fileBody for passing a template file that uses Gatling EL - sspBody for passing a SSP template - byteArrayBody Cheers, Stéphane ---

Perfect Stéphane!! Thanks so much! Yes, I’ll pull and use the 2.0.0-SNAPSHOT! Glad I asked! Thanks for your help! Matt ---

Do you have instructions on how to use the snapshot version? I see that I can grab the individual jars for each gatling module from the maven repo, but I don’t see a complete download .tar.gz. I also tried grabbing the trunk code from git and running “mvn package” (which also build the individual module jars). Is there a command to produce the bundle .tar.gz? Or can I just take my 1.4.1 binary directory and delete all the gatling\*.jar files and replace them with the 2.0-SNAPSHOT versions? (I suspect some of the other dependencies might need to be updated too). Thanks for your help! Matt ---

The bundles are in the repo too: [http://repository-gatling.forge.cloudbees.com/snapshot/com/excilys/ebi/gatling/highcharts/gatling-charts-highcharts/2.0.0-SNAPSHOT](http://repository-gatling.forge.cloudbees.com/snapshot/com/excilys/ebi/gatling/highcharts/gatling-charts-highcharts/2.0.0-SNAPSHOT) You’ll probably have to delete your gatling-recorder.ini, it might not be compatible.
