帶有 JMeter 的 HTTP/2 請求因“nullSession”而失敗 (jetty-alpn)

[英]HTTP/2 Request with JMeter fails with “nullSession” (jetty-alpn)

 原文  2020-07-03 11:15:57  7   1    jmeter/ jetty/ http2/ blazemeter/ alpn

問題描述

我已經為 JMeter 安裝了Blazemeter HTTP/2 插件，但無法讓 HTTP/2 請求正常工作。

我的最小測試如下所示：

截屏

  • 線程組
    • HTTP2 請求
      • 服務器：stackoverflow.com
      • 協議：https
    • 查看結果樹 Http2

運行測試會在視圖結果樹中顯示以下采樣器結果：

我的設置：

我在 Linux（ version 5.6.15-arch1-1 ）上使用 JMeter 5.2.1 和 OpenJDK 8（ openjdk version "1.8.0_252" ）

（在 Ubuntu 20.04 上使用 JMeter 5.3 得到相同的結果，在 CLI 模式下運行）

根據 HTTP/2 插件的要求，我在jmeter啟動腳本的頂部添加了以下行：

JVM_ARGS="-Xbootclasspath/p:/opt/jmeter/lib/alpn-boot-8.1.13.v20181017.jar"

如何解決或調試此問題？

更新：

我發現一旦我使用上面提到alpn-boot ，我對常規 HTTP 請求的行為相同，所以這似乎是該庫的問題。 There is a mapping table for jetty-alpn versions against Java versions at https://github.com/jetty-project/jetty-alpn/blob/master/docs/version_mapping.properties and it currently does not contain my Java version.

文檔說

該表僅顯示了到 OpenJDK 8u242 的映射，這是需要 ALPN 引導 jar 的最后一個版本。

但是如果我在沒有 alpn 參數的情況下啟動 JMeter ，我會看到這樣的結果（HTTP/2 with HTTPS）：

Response code:Non HTTP response code: java.util.concurrent.ExecutionException
Response message:Non HTTP response message: java.lang.IllegalStateException: No Client ALPNProcessors!

1 個解決方案

解決方案1
 1 已采納  2020-07-29 08:37:38

我發現，OpenJDK 8u252 和 Jetty 9.4.26（JMeter 附帶）的組合不兼容。

ALPN API 已向后移植到 Java 8u252 和 Jetty 9.4.28，不再需要alpn-boot 。

更多信息： https://webtide.com/jetty-alpn-java-8u252/

將 Jetty 庫更新到 9.4.28 有助於：
