如何从 WebDriver Sampler 中设置 JMeter Vars？

// I had previously used a CSS/JQuery extractor to get a URL from a page and add it to JMeter vars - accessing it here
var pageURL = "${valueFromJmeterVars}";

// navigate to that url
WDS.browser.get(pageURL); 

// selecting an element
var button = wait.until(pkg.ExpectedConditions.visibilityOfElementLocated(pkg.By.cssSelector(buttonLocator)));                                                                                                                                               

// log desired boolean value to console, so I can confirm is as expected
WDS.log.info('reserveASpotButton:' + reserveASpotButton.isEnabled());

// add my boolean to JMeter vars, so I can access later from beanshell post-processor (where I do my assertions)
vars.put("reserveASpotButtonIsEnabled", reserveASpotButton.isEnabled());

上面的最后一行不起作用。

我可以成功使用 CSS/JQuery Extractor 向 JMeter 变量添加值...

但是我怎样才能在 WebDriver Sampler 中做同样的事情呢？

您可以从 WebDriver Sampler 中访问 JMeter API 类，它的实现为JSR 223标准 https://jcp.org/en/jsr/detail?id=223例如，您可以参考 JMeter 变量（又名vars如下）

在 WebDriver 采样器中：

var ctx = org.apache.jmeter.threads.JMeterContextService.getContext()
var vars = ctx.getVariables();

vars.put('foo','bar')

现在你有${foo}变量的值为bar
