How can I let this route match the url /api/ping which doesn’t contain the id part? And in this case, the desirable id value would be “”.

(def router
    (r/router
     [["/api/ping/:id" ::ping]]))

Maybe this might help?

This would match "/api/starships" and "/api/starships/:id"

dharrigan15:01:30

so if you put your ping as a separate route, then with "" and "/:id" nested underneath

Hi can anyone point me to the documentation of reitit.ring.coercion? I want to inspect a header with it.

I'm having this message in pedestal-swagger example with a post handler

["/custom-gql"
            {:post {:handler (fn [ctx]
                               {:foo :bar})
                    :parameters {:body string?}}}]

Do you have idea what is the root cause ?

delaguardo12:01:43

Your handler should return ring response. Try to wrap like this {:status 200 :body {:foo :bar}}

#Also sent to the channel

I've changed to, and it remains. The message says muuntaja/format-response , I've tried to find the message on muuntaja code, I rly don't know what is happening. Probably something awful on my part. To eliminate that I've introduced this handle in pedestal-swagger example, and the result is similar

["/custom-gql"
            {:post {:handler
                    (fn [ctx]
                      {:status 200 :body
                       {"foo" "bar"}})
                    :parameters {:body string?}}}]

dharrigan19:01:24

Would it be the case that your body is spec'ed out to be a string, but you're sending a JSON object that Jackson is trying to deseralise as foo with a value of bar, i.e., a map like structure?

dharrigan19:01:56

so Jackson is failing to deserialize and thus can't find any thing resembling a (java) bean

dharrigan19:01:49

would it work if you spec it out like this?

dharrigan19:01:10

....`:parameters {:body {:foo string?}}`

geraldodev20:01:06

i've introduced parameters :body string? to send a string to the server, the error happen on leave stage so It does not look like it. I'm changing to :body any? to see what happens

geraldodev20:01:05

@U11EL3P9U man you are right! thank you.

dharrigan21:01:22

no problemo! Glad it's working now for you. 🙂
