情景期间的 Gatling 开关协议

Question

我正在尝试创建一个 Gatling 场景，它需要在测试期间将协议切换到不同的主机。用户旅程是

https://example.com/page1
https://example.com/page2
https://accounts.example.com/signin
https://example.com/page3

所以作为单个场景的一部分，我需要以太切换场景设置中定义的 protocol，或者切换协议中定义的 baseUrl 但我无法弄清楚怎么做。

基本场景可能如下所示

package protocolexample

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

class Example extends Simulation {
  val exampleHttp = http.baseURL("https://example.com/")
  val exampleAccountsHttp = http.baseURL("https://accounts.example.com/")

  val scn = scenario("Signin")
    .exec(
      http("Page 1").get("/page1")
    )
    .exec(
      http("Page 2").get("/page2")
    )
    .exec(
      // This needs to be done against accounts.example.com
      http("Signin").get("/signin")
    )
    .exec(
      // Back to example.com
      http("Page 3").get("/page3")
    )

  setUp(
    scn.inject(
      atOnceUsers(3)
    ).protocols(exampleHttp)
  )
}

我只需要弄清楚如何在第 3 步中切换主机或协议。我知道我可以创建多个场景，但这需要是跨多个主机的单个用户流。

我试过直接使用其他协议

exec(
  // This needs to be done against accounts.example.com
  exampleAccountsHttp("Signin").get("/signin")
)

这导致

protocolexample/example.scala:19: type mismatch;
 found   : String("Signin")
 required: io.gatling.core.session.Session
       exampleAccountsHttp("Signin").get("/signin")

并根据请求更改基础 URL

exec(
  // This needs to be done against accounts.example.com
  http("Signin").baseUrl("https://accounts.example.com/").get("/signin")
)

这导致

protocolexample/example.scala:19: value baseUrl is not a member of io.gatling.http.request.builder.Http

Answer 1

您可以使用绝对 URI（包含协议）作为 Http.get、Http.post 等的参数。

class Example extends Simulation {
  val exampleHttp = http.baseURL("https://example.com/")
  val scn = scenario("Signin")
    .exec(http("Page 1").get("/page1"))
    .exec(http("Page 2").get("/page2"))
    .exec(http("Signin").get("https://accounts.example.com/signin"))
    .exec(http("Page 3").get("/page3"))
  setUp(scn.inject(atOnceUsers(3))
    .protocols(exampleHttp))
}

参见：https://gatling.io/docs/current/cheat-sheet/#http-protocol-urls-baseUrl

baseURL: Sets the base URL of all relative URLs of the scenario on which the configuration is applied.
