Jmeter 5.5 XML SMTP 采样器配置 - 无法设置标头

Question

我正在尝试使用此 .jmx 文件（XML）设置本地 Jmeter 运行：

<?xml version="1.0" encoding="UTF-8"?>
<jmeterTestPlan version="1.2" properties="5.0" jmeter="5.4">

        </SmtpSampler>
        <hashTree/>
      </hashTree>
    </hashTree>
  </hashTree>
</jmeterTestPlan>

此 XML 将电子邮件消息发送到位于 localhost:8080 的本地服务器，没有任何错误。

但是，我想为这些电子邮件设置日期标题。 在SmtpSampler 元素前面，我尝试添加这样的 HeaderManager：

<HeaderManager guiclass="HeaderPanel" testclass="HeaderManager" testname="HTTP Header Manager" enabled="true">
          <collectionProp name="HeaderManager.headers">
            <elementProp name="Date" elementType="Header">
              <stringProp name="Header.name">Date</stringProp>
              <stringProp name="Header.value">Fri, 21 Nov 1997 09:55:06 -0600</stringProp>
            </elementProp>
          </collectionProp>
        </HeaderManager>

但是这个 XML 没有正确设置 SMTP 消息的标头。

我尝试用扩展元素替换 <collectionProp name="SMTPSampler.headerFields"/>：

<collectionProp name="SMTPSampler.headerFields">
            <elementProp name="Date" elementType="Header">
              <stringProp name="Header.name">Date</stringProp>
              <stringProp name="Header.value">Fri, 21 Nov 1997 09:55:06 -0600</stringProp>
            </elementProp>
          </collectionProp>

这导致以下堆栈跟踪：

java.lang.ClassCastException: class org.apache.jmeter.protocol.http.control.Header cannot be cast to class org.apache.jmeter.config.Argument (org.apache.jmeter.protocol.http.control.Header and org.apache.jmeter.config.Argument are in unnamed module of loader org.apache.jmeter.DynamicClassLoader @372f7a8d)

我也试过这个：

<collectionProp name="SMTPSampler.headerFields">
              <elementProp name="date" elementType="Argument">
                <stringProp name="Argument.name">Date</stringProp>
                <stringProp name="Argument.value">Fri, 21 Nov 1997 09:55:06 -0600</stringProp>
              </elementProp>
            </collectionProp>

此配置也失败。

我很想看到在 SMTP Sampler XML 中设置标头的示例，但我在官方 Apache 文档中找不到任何内容。

谢谢！

正如其名称所证明的那样，HTTP Header Manager 控制 HTTP 协议的标头

如果您需要为SMTP protocol 添加标题，SMTP sampler 中有一个特殊的输入：

或者，如果您更喜欢手动编辑 XML：

<collectionProp name="SMTPSampler.headerFields">
  <elementProp name="foo" elementType="Argument">
    <stringProp name="Argument.name">foo</stringProp>
    <stringProp name="Argument.value">bar</stringProp>
  </elementProp>
</collectionProp>
