可能是什么原因？ 谢谢！

Answer 1

很可能您的 JMeter 安装以某种方式损坏，尝试使用 JMeter Plugins Manager 卸载 jmeter - HTTP Protocol Support 组件，然后重新安装它

它应该可以解决您的安装问题。

还要注意according to JMeter Best Practices you should always be using the latest version of JMeter，因此鉴于您当前的 JMeter 安装已损坏，可能是升级到 JMeter 5.3 的好时机（或在 JMeter Downloads 页面上提供的最新稳定版本）

Answer 2

我已经通过在每次测试中重新配置 HTTP 请求来修复它。
