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?

[dave]

you don't need the prefixing /

[Cosmin Victor Celea]

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

[Cosmin Victor Celea]

?

[dave]

yep

[Cosmin Victor Celea]

still the same error

[Cosmin Victor Celea]

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

[dave]

Hmmm. Can you stick it in a gist please?

[Cosmin Victor Celea]

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 {

[Cosmin Victor Celea]

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

[Cosmin Victor Celea]

Could this be it?

[Cosmin Victor Celea]

How would you define the endpoint in this case?

[dave]

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

[dave]

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

[dave]

Limitation of how it’s written I’m afraid

[dave]

(And the type system)

[Cosmin Victor Celea]

but if both weather and feed are static

[Cosmin Victor Celea]

then i still have to write

[Cosmin Victor Celea]

Path.of(“weather”) / “feed”

[dave]

Aha - then “weather” / “feed”

[Cosmin Victor Celea]

aha ok

[Cosmin Victor Celea]

thank you, will try

[dave]

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

[dave]

(Haven’t got api in front of me)

[Cosmin Victor Celea]

👍 will try both

[Cosmin Victor Celea]

thank you

[dave]

👍

[Cosmin Victor Celea]

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

[Cosmin Victor Celea]

so for example getfeed(weatherPath: String): HttpHandler

[dave]

Yep.

[dave]

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.. 🙄
