Wiremock模板固定延迟毫秒

Question

我正在尝试在延迟后在wiremock中生成响应，其中延迟来自传入的请求。e、 g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_\"))'}}"
  }
}

谁能确认哪些字段可以模板化吗。doco建议使用“响应头和正文”，其他地方建议使用bodyFileName（我正在使用），但它没有说明其他响应字段是否可以模板化。

现在我看到了

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/wire mock/blob/master/src/main/Java/com/github/tomakehurst/wire mock/standalone/jsonfilemappings source . Java # L121

其次，我不清楚我是否只是驱动了电线，这不可能通过响应变压器，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——但是如果它是动态的，那就更好了。

感谢帮助！

Answer 1

因此，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字符串，但是 fixedDelayMillise秒需要一个数字，因此WireMock会将错误抛:(

我认为您可以使用自定义转换器来扩展WireMock，该转换器将解析响应正文中的延迟并将其添加为响应中的数字。有关更多信息，请查看扩展WireMock留档。编辑：我现在看到您已经达到了这个假设。我认为您是对的：D-这是通过转换器最容易实现的。

Answer 2

我有一个类似的问题，我创建了一个响应定义扩展，它在提供时从标题中获取它。

class InjectDelayFromHeader : ResponseDefinitionTransformer() {
  override fun getName() = "InjectDelayFromHeader"

  override fun transform(
    request: Request,
    response: ResponseDefinition,
    files: FileSource, 
    parameters: Parameters
  ): ResponseDefinition {
    val delay = request.getHeader("X-WIREMOCK-DELAY")
    if (delay.isNullOrBlank()) {
      return response
    }
    return ResponseDefinitionBuilder.like(response).withFixedDelay(Integer.valueOf(delay)).build()
  }
}
