Wiremock模板fixedDelayMilliseconds

Question

我试图在一段延迟之后在wiremock中生成一个响应，其中该延迟是从传入的请求派生的。例如，请求中用户的家庭名称是"delay_10000“，然后延迟10000毫秒，或者delay_20000，然后延迟20000.....

{
  "request": {
    "method": "POST",
    "headers": {
      "SOAPAction": {
        "matches": "http://redacted"
      }
    },
    "bodyPatterns": [
      {
        "matchesXPath": {
          "expression": "//*[local-name()=\"family-name\"]/text()",
          "matches": "^delay_([0-9]+)$"
        }
      }
    ]
  },
  "response": {
    "status": 200,
    "bodyFileName": "verify.xml",
    "fixedDelayMilliseconds": "{{soapXPath request.body 'number(substring-after(//*[local-name()=\"family-name\"]/text(), \"delay_\"))'}}"
  }
}

谁能确认哪些字段能够被模板化。文档建议"response headers and be“，以及其他地方的bodyFileName (我正在工作)，但它没有提到是否可以将其他响应字段模板化。

现在我看到的是

首先，我可以看到它被捕获的位置，但不能清楚地看到它被抛出的位置https://github.com/tomakehurst/wiremock/blob/master/src/main/java/com/github/tomakehurst/wiremock/standalone/JsonFileMappingsSource.java#L121

其次，我不清楚我是否只是错误地驱动了wiremock，这不可能通过响应转换器实现，但可以通过扩展和“响应定义转换”(http://wiremock.org/docs/extending-wiremock/)来实现。

我可以通过一组固定的延迟来解决这个问题--但如果它是动态的就更好了

感谢您的帮助！

所以我最初的假设是这是不可能的，因为模板的任何使用都将解析为一个字符串，但是fixedDelayMilliseconds需要一个数字，所以WireMock将抛出错误:(

我认为您可以使用自定义转换器来扩展WireMock，它将解析响应正文中的延迟，并将其作为数字添加到响应中。有关更多信息，请查看Extending WireMock文档。编辑:我现在明白了，你已经得出了这个假设。我想你是对的:D --这是最容易通过变压器实现的。
