我试图在延迟后在wiremock中生成响应，该延迟来自传入的请求。例如，请求中用户的姓氏是“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_\"))'}}"
  }
}

任何人都可以确认哪些字段可以被模板化。doco 建议“响应标头和正文”，以及其他地方的 bodyFileName （我有工作），但它没有说明其他响应字段是否可以模板化。

目前我看到

首先，我可以看到它在哪里被捕获，但不清楚它在哪里被抛出 https://github.com/tomakehurst/wiremock/blob/master/src/main/java/com/github/tomakehurst/wiremock/standalone/JsonFileMappingsSource。爪哇#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/ )

我可以用一组固定的延迟来解决这个问题——但如果它是动态的会更好

帮助表示赞赏！

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会解析为一个字符串，但fixedDelayMilliseconds需要一个数字，所以 WireMock 会抛出错误:(

我认为您可以使用自定义转换器扩展 WireMock，该转换器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，请查看扩展 WireMock文档。编辑：我现在看到您已经得出了这个假设。我认为你是对的：D——这很容易通过变压器实现。
