Gatling脚本——我如何在下面的请求中为eventdatetime提供不同的历元时间

Question

Gatling Scripts-如何在下面的请求中以不同的纪元时间作为馈送器馈送eventDateTime。Id以循环方式通过馈送器馈送。以下请求位于使用ELFilebody馈送的文件中。event-new.json看起来像

{
  "events": [
    {
      "eventDataModel": {
        "eventStatus": "ON",
        "eventDateTime": 1598271042436
      },
      "transactionModel": {
        "id": "${ID}"
      }
    },
    {
      "eventDataModel": {
        "eventStatus": "ON",
        "eventDateTime": 1598271043436
      },
      "transactionModel": {
        "id": "${ID}"
      }
    },
    {
      "eventDataModel": {
        "eventStatus": "ON",
        "eventDateTime": 1598271044436
      },
      "transactionModel": {
        "id": "${ID}"
      }
    },
    {
      "eventDataModel": {
        "eventStatus": "ON",
        "eventDateTime": 1598271045436
      },
      "transactionModel": {
        "id": "${ID}"
      }
    },
    {
      "eventDataModel": {
        "eventStatus": "ON",
        "eventDateTime": 1598271046436
      },
      "transactionModel": {
        "id": "${ID}"
      }
    },
    {
      "eventDataModel": {
        "eventStatus": "ON",
        "eventDateTime": 1598271047436
      },
      "transactionModel": {
        "id": "${ID}"
      }
    },
    {
      "eventDataModel": {
        "eventStatus": "ON",
        "eventDateTime": 1598271048436
      },
      "transactionModel": {
        "id": "${ID}"
      }
    },
    {
      "eventDataModel": {
        "eventStatus": "OFF",
        "eventDateTime": 1598271049436
      },
      "transactionModel": {
        "id": "${ID}"
      }
    }
  ]
}

以上是使用gatling脚本片段发布的event-new.json

val idFeeder = csv("Id.csv").circular
val trip_dte2 = scenario("Event")
                    .feed(idFeeder)
                    .exec(http("event")
                    .post( event_url)
                    .headers(headers)
                    .body(ElFileBody("event-new.json")).asJSON
                    .check(status.is(201)))

Answer 1

截至加特林3.3：

scala prettyprint-override">.exec { session =>
  session.set("timestamp", System.currentTimeMillis())
}

然后用${timestamp}替换1598271049436。

或者，在Gatling 3.4中：如果您可以在JSON有效负载中为每次出现设置不同的值，则直接将1598271049436替换为${电流时间米利斯（）}。
