无法通过JMeter发送HTTP2请求

Posted 2021-04-21

我正在尝试通过JMeter发送HTTP2请求。

我已根据我的Java版本下载了alpn-boot文件：Java版本“ 1.8.0_151”-> ALPN版本为8.1.11.v20170118（根据https://www.eclipse.org/jetty/documentation/9.4.x/alpn-chapter.html#alpn-versions）。另外，我已经将alpn-boot文件的路径添加到jmeter.bat：

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

但是我在JMeter中收到一条错误消息：

我想这个问题与jmeter.bat文件中的alpn路径有关，但是如何解决？

答案

1. 首先确保JMeter使用Java 1.8.0_151并采用-Xbootclasspath参数，您可以通过添加JSR223 Sampler并使用以下Groovy代码来做到这一点：

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

   您应该获得如下输出：
   

2. 检查alpn-boot文件是否在[[真正：

   

清理输入，即删除空格，在末尾添加分号，并用引号引起来的值：

3. set JVM_ARGS="-Xbootclasspath/p:D:apache-jmeter-5.1apache-jmeter-5.1libalpn-boot-8.1.11.v20170118.jar;"

如果一切顺利，您应该能够成功执行HTTP2请求：
