加特林测试中未更新进纸器值

Question

我是 scala 和 gatling 的新手。我正在尝试从 feeder 和 post zip 文件中获取值到 service 。但是 ${extensionId} 没有用获取的值更新，而是保持为 ${extensionId} 。有人可以帮助我知道如果我在这里遗漏了什么。

          def installExtension() =
            exec(http("template - Install Extension")
              .post(url + "/v1/extensions")
              .basicAuth("jack", "password")
              .headers(namespaceHeader)
// using testUtils to get InputStream conte
              .body(InputStreamBody(TestUtils.toStream(hashMap.get("${extensionId}").getOrElse(null))))
              .check(status.is( 201)))


 class extmgrSimulations extends Simulation {

          val extensionIds = csv(s"${Configuration.dataDirectory}/extensionId.csv").circular


          val extMgrScenerio = scenario("extensionMgr - Scenario")
            .during(Configuration.duration) {
              exitBlockOnFail(
                group("load-test") {
                  exec(
                    pace(Configuration.paceFrom, Configuration.paceTo),
                    feed(extensionIds),feed(extensionIds)
                      randomSwitch(
                      50.00 -> group("Install and delete") {
                        exec(
                          extmgrChain.installExtension(),
                          extmgrChain.deleteExtension(),
                        )
                      },
                      50.00 -> extmgrChain.listExtension()
                    )
                  )
                }
              )
            }

那不行。 Gatling EL（字符串中的 ${} 语法）并不能在任何地方神奇地工作。 documentation.

中对此进行了解释

Warning

This Expression Language only works on String values being passed to Gatling DSL methods. Such Strings are parsed only once, when the Gatling simulation is being instantiated.

For example queryParam("latitude", session => "${latitude}") wouldn’t work because the parameter is not a String, but a function that returns a String.

Also, queryParam("latitude", "${latitude}".toInt) wouldn’t because the toInt would happen before passing the parameter to the queryParam method.

The solution here would be to pass a function:

session => session("latitude").validate[Int].
