如何在PUT请求中设置计数器？

Question

我有两个URL，第一个是BaseURL创建用户，第二个是用来为asLongAs循环中的每个用户设置密码。我在第二个url请求中设置“计数器”时遇到问题，即“更改密码”。它在错误下面抛出，

9425[GatlingSystem-akka.actor.default-调度-11]ERRORi.g.http.action.HttpRequest estAction-'httpRequest-4'执行失败：未定义名为'计数器'的属性

我无法在这里设置计数器，

.exec(http("Change_Password")
            .put(setPasswordURL + "/api/authentication/accounts/" + accountName + "/users/" + unm + "${counter}/actions/setPassword")

如果我把静态值放入。提出请求。

这是密码，

    }

你可以用不雅的方式使用加特林请求id。

.exec{session => session.set("number",session.userId.split("-").last.toInt)}
.exec{session => session("number").as[Int] }

我用它每10个请求和每100个请求调用一个请求。

.exec{session => session.set("number",session.userId.split("-").last.toInt)}
.exec(request1)
.doIf(session => session("number").as[Int] % 10 == 0) {
   exec(request2)
   .doIf(session => session("number").as[Int] % 100 == 0) {
      exec(pause(10 seconds))
      .exec(request3)
      .exec(pause(4 seconds))
      .exec(request4)
   }
}
