無法通過 JMeter 發送 HTTP2 請求

Question

我正在嘗試通過 JMeter 發送 HTTP2 請求。

I've downloaded alpn-boot file according to my java version: java version "1.8.0_151" -> ALPN version is 8.1.11.v20170118 (according to https://www.eclipse.org/jetty/documentation/9.4. x/alpn-chapter.html#alpn-versions ）。 此外，我已將 alpn-boot 文件的路徑添加到 jmeter.bat：

set JVM_ARGS= -Xbootclasspath/p:D:\apache-jmeter-5.1\apache-jmeter-5.1\lib\alpn-boot-8.1.11.v20170118.jar
@echo off

但我在 JMeter 中收到一條錯誤消息：

我猜這個問題與 jmeter.bat 文件中的 alpn 路徑有關，但如何糾正呢？

Answer 1

1. 首先確保 JMeter 正在使用您的 Java 1.8.0_151 並采用-Xbootclasspath參數，您可以通過添加JSR223 采樣器並使用以下Z2D19C57FDD48FDC2170代碼來做到這一點：

    log.info('Java version: ' + System.getProperty('java.version')) java.lang.management.ManagementFactory.getRuntimeMXBean().getInputArguments().each { log.info("Effective JVM argument: " + "$it") }

   你應該得到 output 像：

   

2. 檢查alpn-boot文件是否真的存在：

   

3. 清理輸入，即刪除空格，在末尾添加分號並用引號將值括起來：

    set JVM_ARGS="-Xbootclasspath/p:D:\apache-jmeter-5.1\apache-jmeter-5.1\lib\alpn-boot-8.1.11.v20170118.jar;"

4. 如果一切順利，您應該能夠成功執行 HTTP2 請求：
