无法在JMeter中记录Power Bi嵌入Web应用程序.app.powerbi.com引发错误

问题描述

我正在使用Apache JMeter 5.3。当我的应用程序点使用代理连接到https://app.powerbi.com时，我遇到了问题。我尝试在代理后面使用，它没有帮助。

请帮助我解决错误消息

错误消息：

解决方法

看&，您正在尝试使用IPv6 implementation获取app.powerbi.com的IP地址。

根据https://en.wikipedia.org/wiki/IPv6，该网站不支持IPv6

您可能想通过将下一行添加到 system.properties 文件中来restrict Java TCP/IP stack to IPv4 only：

 val df = Seq((25,10,"a&c","i&j&k"),(35,15,"a&b&d","i&k")
      .toDF("num1","num2","x","y")
  val dfProcessed = df.withColumn("x",split($"x","&"))
      .withColumn("y",split($"y","&"))
      .select("num1","y")

    val headers = Seq("a","b","c","d","i","j","k")
    val report = dfProcessed.select(Seq("num1","num2").map(col) ++ headers.map(line => array_contains('x,line)
      || array_contains('y,line) as line) : _*)

    report.show()

需要重新启动JMeter才能获取该属性。

或者，您可以考虑使用另一种记录方式：JMeter Chrome Extension，使用它时，您不必担心代理，证书，协议版本等。
