Answer 1

我相信您正面临Connection Reset since JMeter 2.10 ? JMeter wiki 页面中描述的问题。如果您完全确定您的被测应用程序的行为是正确的，并且不需要在后端进行任何调整或调整，您可以将 JMeter 配置为重试拒绝的连接并检查陈旧的连接：

1. 将所有 HTTP 请求采样器的“实施”更改为 HttpClient4。最简单的方法是使用HTTP Request Defaults 配置元素。

2. 在您安装的 JMeter 的 /bin 文件夹下的 user.properties 文件中添加以下属性：

   httpclient4.retrycount=1
   hc.parameters.file=hc.parameters
   

3. 将下一行添加到 hc.parameters 文件（相同位置，JMeter 的 /bin 文件夹）

   http.connection.stalecheck$Boolean=true
   

4. 重新启动 JMeter。

您的“连接重置”问题应该会消失。
