RandomUtils.nextLong(10L,1000L) 在 JMeter HTTP 请求正文中失败并显示 "unexpected token: 10L"

Question

我必须在我的一个 HTTP 请求正文数据中传递一个随机长值。

我使用的代码是"${__groovy(import org.apache.commons.lang3.RandomUtils;RandomUtils.nextLong(10L,1000L);)}"

我已经在 JSR223 预处理器中尝试了 groovy 的相关 groovy 代码，它正确地打印出了数字；

long rand = org.apache.commons.lang3.RandomUtils.nextLong(2000, 10000);
log.info("random   [" + rand + "]");

但是当我在 HTTP 请求正文中的 __groovy() 中使用相同的代码时，它失败并显示 ;

我可以看到我可以获得其他 groovy 脚本，例如 "${__groovy(new Date().format("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'" );)}" 在 HTTP 请求正文数据中工作正常。

我在这里错过了什么？

更新： 我也尝试了没有 "L" 甚至 RandomUtils.nextLong(10,1000); 相同异常的代码。

Answer 1

https://jmeter.apache.org/usermanual/functions.html#__groovy

Argument values that themselves contain commas should be escaped as necessary. If you need to include a comma in your parameter value, escape it like this: \,

所以，应该是这样的：

${__groovy( org.apache.commons.lang3.RandomUtils.nextLong(10\,1000) )}

Answer 2

您需要像这样转义逗号：

${__groovy(return org.apache.commons.lang3.RandomUtils.nextLong(10\, 1000),)}

下次考虑使用 The Function Helper Dialog 以获得 JMeter 函数的正确语法。

通常建议使用 JMeter 的内置测试元素 and/or 函数并尽可能避免编写脚本，因此请考虑使用 __Random() function，相关语法为：

${__Random(10,1000,)}

如果您提供第三个参数 - JMeter 会将生成的值存储在变量中。
