如何在Gatling中忽略失败的请求

import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._

class MySimulation extends Simulation {

  val httpConf = http.baseUrl("http://example.com") // 设置基础URL

  val scn = scenario("My Scenario")
    .exec(http("My Request")
      .get("/my-endpoint")
      .check(status.is(200))) // 检查请求的状态码是否为200

  setUp(
    scn.inject(
      rampUsersPerSec(10) to 100 during (1 minute) // 设置并发用户数从10逐渐增加到100，持续1分钟
    )
  ).protocols(httpConf)
   .assertions(
     global.failedRequests.percent.lt(5) // 设置失败请求的百分比小于5%
   )
   .ignoreFailedRequests // 忽略失败的请求
}
