something strange seems to be happening with my app:

post("/webhook", {
            print("yes")
            val post = call.receiveParameters()
            print("yes")

It could be if sender of POST request is not sending any data and not sending an indication of empty request (Content-Length: 0 or zero-chunk), and not closing connection. In this case the handler is suspended and waiting for data.

How do you send the data to webhook?

[warriorprincess]

using curl

curl -H "Content-Type: application/json" -X POST "localhost:1337/webhook" -d '{"object": "page", "entry": [{"messaging": [{"message": "TEST_MESSAGE"}]}]}'

basically I am just following the Facebook dev guide for making a chat bot

I will need to check it locally. Will be able to do it later today.

[warriorprincess]

Okay thanks a lot. 🙂

[orangy]

Wait, you’re likely having an exception in log. receiveParameters will not work with JSON, it is for form posts (multipart or urlencoded). If you need to receive a data object, you need to setup ContentNegotiation and recieve a data object.

[warriorprincess]

No exceptions showing up in run tab on intellij...but this is probably the reason.

[orangy]

Did you setup logging?

[orangy]

I mean, did you read the gradle guide to the end? 😄

[warriorprincess]

Ah no I didn't 😛. I did read it but figured I could do without logging to begin with

[warriorprincess]

will set it up now (y)

[warriorprincess]

also any link to the documentation on receiving data object?

[warriorprincess]

i.e. content negotiation for json

[orangy]

Not yet… but check samples!

Alright will do 🙂

[Deactivated User]

Nice! Thanks for asking, that helps a lot to locate things that are missing 🙂 I’m still with the Requests/Responses stuff, but will enqueue this too 👍

[warriorprincess]

Happy to help any way I can. 🙂 I've been a huge Jetbrains fan for years.

Added a Requests page (hope it is helpful):

http://ktor.io/servers/requests.html

And a section about the ContentNegotiation:
http://ktor.io/servers/requests.html#receiving-content-negotitation

Let me know if something is not clear or if you have troubles with other things so I can improve it.
