Question

Apache Jmeter版本3.2 r1790748- HTTP请求中缺少实现选项，任何人都可以指出如何启用此选项。

我正在尝试使用jmeter关注post方法的视频教程，我得到以下错误..

我没有选择的选项是implementation-java，我可以在我的jmeter版本中找到它。

Answer 1

从JMeter 3.2开始，您可以找到＆＃34;实施＆＃34;下载＆＃34;高级＆＃34; Beanshell vs JSR223 vs Java JMeter Scripting: The Performance-Off You've Been Waiting For!采样器的标签

HTTP Request

我建议使用修改它，因为这样您不仅可以为范围内的所有HTTP请求采样器设置设置，而且如果您改变主意，则需要更改实现到一个地方的HTTPClient4。
