Check for request response body match

[kescherCode]

Currently, we can only check for an exact body to consider a fail.
However, some of my monitored services have their own internal monitoring, which would make it easy to report if something in the body does NOT match the expected sane values.

So, you're saying, like we can use __dangerous__body_down to check if something is in the body and mark the site as down:

sites:
  - name: Custom down
    url: https://example.com
    __dangerous__body_down: "File not found"

We can do __dangerous__body_down_if_text_missing:

sites:
  - name: Custom down
    url: https://example.com
    __dangerous__body_down_if_text_missing: "Everything looks good"

In the above example, if the body doesn't include the text "Everything looks good", we'll mark the site as down. Is this right? Happy to add this feature.

Yes, this is exactly what I had in mind ^^

Done, this has been added in @upptime/[email protected]:

sites:
  - name: Custom down
    url: https://example.com
    __dangerous__body_down_if_text_missing: "Everything looks good"
    __dangerous__body_degraded_if_text_missing: "Everything is fast"

This should be mentioned in docs

I think it is a bit sad to only be able to match against one "word". Would it be possible to match against a regex or perhaps easier doable in yaml: a list of elements?
