如何使用Scala语言在Gatling中从Raw（非文本）响应中获取数据？

Question

我正在尝试从API响应中获取数据，该API响应以文本，原始，HTML和十六进制形式返回。 在这里，加特林从文本响应中获取数据，而文本响应返回空白。 有什么方法可以从原始响应中获取数据吗？

这是API原始响应：

pragma: No-cache
cache-control: no-cache,no-store,max-age=0

and I have written this script to get a data:
.check(regex("keyto=(.*)").saveAs("corr_krypto"))

I've tried to disableFollowRedirect to this service
I've tried to get the data that I need from another service but I found it only into this service.
