无法在Gatling中发送http/2请求

Question

我在尝试发送超文本传输协议/2请求时遇到了使用gatling工具的问题。

我在协议设置中启用了超文本传输协议/2设置，甚至添加了映射以确保客户端将使用http2与服务器通信，但仍然使用超文本传输协议/1.1发送请求。

在控制台输出中，您将看到服务器可以使用http2进行通信，但由于某些原因，请求仅使用http1.1发送。

所有标题都是根据浏览器中的标题编写的。

有人能帮我解决这个问题吗？

package test

import scala.concurrent.duration._

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

class RecordedSimulation extends Simulation {

    val httpProtocol = http
        .baseUrl("https://sitename")
        .inferHtmlResources(BlackList(""".*\.js""", """.*\.css""", """.*\.gif""", """.*\.jpeg""", """.*\.jpg""", """.*\.ico""", """.*\.woff""", """.*\.woff2""", """.*\.(t|o)tf""", """.*\.png""", """.*detectportal\.firefox\.com.*"""), WhiteList())
        .acceptHeader("*/*")
        .acceptEncodingHeader("gzip, deflate")
        .acceptLanguageHeader("en-US,en;q=0.5")
        .userAgentHeader("Mozilla/5.0 (Macintosh; Intel Mac OS X 10.16; rv:85.0) Gecko/20100101 Firefox/85.0")
            .enableHttp2
        .http2PriorKnowledge(Map("sitename" -> true))
        .disableCaching
      .disableWarmUp

    val headers_0 = Map(
        "Accept" -> "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
        "Cache-Control" -> "max-age=0",
        "sec-fetch-dest" -> "document",
        "sec-fetch-mode" -> "navigate",
        "sec-fetch-site" -> "none",
        "sec-fetch-user" -> "?1",
        "Upgrade-Insecure-Requests" -> "1")



    val scn = scenario("RecordedSimulation")
        .exec(http("request_0")
            .get("/auth?r=%2F&m=NOT_AUTHENTICATED")
            .headers(headers_0))
        .pause(2)

    setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)
}

在控制台中，我看到下一个：

DEBUG io.gatling.http.client.impl.DefaultHttpClient - ALPN led to HTTP/2 with remote sitename
DEBUG io.gatling.http.client.impl.Http2AppHandler - Write request WritableRequest{request=DefaultFullHttpRequest(decodeResult: success, version: HTTP/1.1, content: UnpooledByteBufAllocator$InstrumentedUnpooledUnsafeHeapByteBuf(ridx: 0, widx: 0, cap: 0))

这些是内部加特林日志。我们使用Netty的方式是将HTTP/1.1有效负载转换为HTTP/2有效负载。从您提供的日志来看，Gatling在这里正确地使用了HTTP/2。
