Jmeter Current Thread Number?
提问by Raju
I am using a Thread Group with Number Of Threads = 5 with an HTTP request.
我在 HTTP 请求中使用线程数 = 5 的线程组。
In the request I want to include a parameter with the value of the thread number, e.g.,
在请求中，我想包含一个带有线程号值的参数，例如，
"pageno": ${threadno}
I want to get the thread number like ${threadno}.
我想获得像${threadno}.
How can I do that?
我怎样才能做到这一点？

While the above-mentioned ${__threadNum}will work in many places within jMeter, you'll need to use something else where it is not allowed, e.g., script elements within Pre/Post-Processors.
虽然上面提到的${__threadNum}将在 jMeter 中的许多地方工作，但您需要使用其他不允许的东西，例如，预处理/后处理器中的脚本元素。
This answer explains how to get thread number or count within such a script in jMeter.
此答案解释了如何在 jMeter 中的此类脚本中获取线程数或计数。
To get the number of the current thread (out of 5 in your case) use ctx.getThreadNum()which will get the number of the thread.
要获取当前线程的数量（在您的情况下为 5 个），请使用ctx.getThreadNum()它将获得线程的数量。
To get the total number of threads being used by jMeter you can use ctx.getThreadGroup().getNumThreads()or ctx.getThreadGroup().getNumberOfThreads()for total active threads.
要获取 jMeter 使用的线程总数，您可以使用ctx.getThreadGroup().getNumThreads()或ctx.getThreadGroup().getNumberOfThreads()活动线程总数。

For those looking for the number of active threads in the entire test plan, not just a particular ThreadGroup.
对于那些在整个测试计划中寻找活动线程数量的人，而不仅仅是特定的 ThreadGroup。
${__groovy(org.apache.jmeter.threads.JMeterContextService.getNumberOfThreads())}

${__threadNum}does not work well alone.
${__threadNum}单独工作并不好。
You will need use ${__eval(${__threadNum})}. Try to use this:
您将需要使用 ${__eval(${__threadNum})}。尝试使用这个：
int threadNum=ctx.getThreadGroup().getNumThreads();
ctx is from JmeterContext
ctx 来自 JmeterContext
