Hei, I get the following error when trying to define a endpoint that starts with a dynamic path. (Example:

Path.of("system", "The target system ") / "/feed"

Exception in thread "main" java.lang.IllegalArgumentException: Fixed path segments cannot contain /. Use the "a / b" form.

Any ideas?

you don't need the prefixing /

Path.of(“system”, “The target system “) / “feed”

dave

yep

Cosmin Victor Celea

still the same error

return  Path.of("system", "The target system ") / "feed" meta {

dave

Hmmm. Can you stick it in a gist please?

I think i figure out where the problem is. In my code the static path is composed of 2 elements. Something like return Path.of(“system”, “The target system “) / “weather/feed” meta {

I think it does not like the “/” between weather and feed

Could this be it?

How would you define the endpoint in this case?

dave

Aha - yes. You would use Path.of(“weather”) / “feed”

With suffix “strings” the bound handler function then takes 2 args- one of them is always “feed”.

Limitation of how it’s written I’m afraid

(And the type system)

but if both weather and feed are static

then i still have to write

Path.of(“weather”) / “feed”

dave

09/02/2020, 10:25 AM

Aha - then “weather” / “feed”

Cosmin Victor Celea

09/02/2020, 10:25 AM

aha ok

thank you, will try

dave

09/02/2020, 10:26 AM

Or if that doesn’t work Path.fixed(“weather”) / “fixed “

(Haven’t got api in front of me)

Cosmin Victor Celea

👍 will try both

thank you

dave

👍

Worked with Path.fixed but the in the HttpHandler i have to have all the paths as inputs

so for example getfeed(weatherPath: String): HttpHandler

dave

Yep.

It’s because the path lens is basically matching on the input string.

Kotlin type system isn’t really powerful enough for what we’d ideally like.. 🙄
