Gatling - 未定义名为“CSRF”的属性

Question

我得到这个错误，我的属性没有定义，我不知道为什么。

我首先将它作为 CSRF 变量保存在我的第一个请求中。
稍后我尝试在发送请求以填写表单时访问它。

这是我的主要模拟课程：

package simulations.stage

import io.ecx.steps.{Config, Login}
import io.gatling.core.Predef._
import io.gatling.core.structure.ScenarioBuilder
import io.gatling.http.Predef._
import io.gatling.http.protocol.HttpProtocolBuilder

import scala.concurrent.duration._

class RampUsersLoadSimulations extends Simulation{

  val httpConf: HttpProtocolBuilder = http.baseUrl(Config.baseUrl)
    .header("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
    .userAgentHeader("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.190 Safari/537.36")
    .inferHtmlResources()
    .acceptEncodingHeader("gzip, deflate, br")
    .proxy(Proxy("localhost", 8866))

  before {
    println(s"Running for: ${Config.baseUrl}")
  }

  val login: ScenarioBuilder = scenario("Scenario: Login to the storefront")
    .exec(
      Login.login(Config.accounts),
      Login.navigateToMyAccountPage())

  setUp(login.inject(atOnceUsers(1))).protocols(httpConf)
}

这是我的步骤对象，我尝试保存它，然后在发布请求中使用它：

package io.ecx.steps

import io.gatling.core.Predef._
import io.gatling.http.Predef._

object Login {

  def login(accountsPath: String) = {
    val accounts = csv(accountsPath).random

      exec(http("Load Login Page")
      .get("/login")
      .check(regex("<title>My Title</title>").exists)
      .check(css("[name=CSRFToken]", "value").saveAs("CSRF"))
      .check(status.is(200)))
      .pause(2)
//      .exec{session => println(session); session}
    feed(accounts)
      .exec(http("Log in with credentials to the storefront")
        .post("/j_spring_security_check")
        .formParam("username", "${username}")
        .formParam("password", "${password}")
        .formParam("rememberMe", "${rememberMe}")
        .formParam("CSRFToken", "${CSRF}")
        .check(css("#loginForm").notExists)
      .check(status.in(200)))
      .pause(5)
  }

  def navigateToMyAccountPage() = {
    exec(http("Open My account Page")
    .get("accountSummary")
    .check(css(".page-AccountSummaryPage").exists)
    .check(status.in(200)))
      .pause(2)
  }
}

在加载登录页面时加载的 HTML 中：

<input type="hidden" name="CSRFToken" value="6ac89c39-ee25-4cdc-9553-cc8a7824f43b" />

这是日志：

难道我有这种行为是因为输入字段被标记为隐藏？
或者有什么我看不到的。

请帮忙。
谢谢！

您的代码中有一个错误：feed(accounts) 之前缺少一个点。因此，它不附加到头部，只考虑尾部。
