JMeter-使用jar输出的URL进行负载测试 [英] JMeter - Use jar output for URL to load test

问题描述

我想使用JMeter测试Java服务.但是，我要测试的URL必须动态生成(时间戳，有效负载哈希等).我创建了一个可输出输出有效URL的自可执行jar.

I would like to use JMeter to test a Java service. However the URL I want to test has to be dynamically generated (timestamps, payload hash, etc). I created a self executable jar that outputs a valid URL.

java -jar file.jar

http://www.example.com/api?params=...

URL每次迭代都会更改.有没有一种方法可以配置JMeter来运行Jar以获取它发出的每个HTTP请求的URL?谢谢！

The URL changes each iteration. Is there a way I can configure JMeter to run the Jar to get the URL for each HTTP request it makes? Thanks!

推荐答案

您需要使用以下各项的组合:

You need to use combination of the following:

1. OS Process Sampler (以产生实用程序JAR)
2. 正则表达式提取器(获取生成的URL)

1. OS Process Sampler (to spawn your utility JAR)
2. Regular Expression Extractor (to get generated URL)

详细信息:

鉴于您的系统路径中有Java二进制文件，您需要执行以下操作:

Given you have java binary in your system path you need the following:

在线程组下添加一个OS Process Sampler

Under Thread Group add an OS Process Sampler

• 将Command设置为 java (要完全确保键入Java二进制文件的完整路径，即"d:\ apps \ java6 \ bin \ java.exe")
• 在命令参数下添加以下内容: -jar * your.jar *在单独的行中，最好还是使用完整路径到jar.
• 在与OS Process Sampler相同级别上添加View Results Tree侦听器

• Set Command to be java (to be completely sure type full path to your java binary, i.e. "d:\apps\java6\bin\java.exe")
• Under Command Parameters add following: -jar *your.jar* EACH ON SEPARATE LINE, again it's better to use full path to your jar.
• Add View Results Tree listener at the same level as OS Process Sampler

如果您运行Thead Group，则应看到以下内容:

If you run your Thead Group you should see the following:

系统调用完成. 过程输出: http://example.com/api?params= ....

System Call Complete. Process Output: http://example.com/api?params=....

我相信您对"params ="

I believe that you're interested in something, which comes after "params="

因此，要获取此值，请添加正则表达式提取器后处理器作为OS Process采样器的子代，并提供以下详细信息:

So get this value add a Regular Expression Extractor Post Processor as a child of OS Process sampler with following details:

• 引用名称-变量的任何有意义的名称，请将其设为"params"
• 正则表达式- http://www.example.com/(.*)
• 模板-$ 1 $

• Reference name - any meaningful name for variable, let it be "params"
• Regular Expression - http://www.example.com/(.*)
• Template - $1$

这将提取api?params = ...，因此您可以将其用作$ {params}

That will extract api?params=... so you'll be able to use it as path for your HTTP Request as ${params}
