I was successfully using IRControl to control a device with HTTP GET requests such as:
192.168.175.51:8080/jsonrpc?request={"jsonrpc":"2.0","method":"Input.Down","id":1}
After updating that device, it now requires HTTP POST requests. I've gotten the following to work from two other programs, but it fails in IRControl.
192.168.175.51:8080/jsonrpc (in the URL field)
{"jsonrpc":"2.0","method":"Input.Down","id":1} (in the Content field)
The stacktrace shows:
java.io.FileNotFoundException:
http://192.168.175.51:8080/jsonrpc
com.android.okhttp.internal.huc.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:255)
ch.cec.ircontrol.o.i.a(Unknown Source:177)
ch.cec.ircontrol.o.i.a(Unknown Source:3)
ch.cec.ircontrol.setup.activity.p$h.run(Unknown Source:150)
ch.cec.ircontrol.d0.n$c.run(Unknown Source:25)
What am I missing? I feel like maybe it needs "Content-Type:application/json" but I'm not sure how to include it.

Re: HTTP POST requests
Hi
Normaly the FileNotfoundException appears when the URL does not exist server side. Could you once set the log level to DEBUG and try it again? Width DEBUG Level there are more informations logged into the log system.
kind regards,
Urs

Re: HTTP POST requests
Hi
FileNotFoundException occurs when the server sends a HTTP Error 404 back to the client. We can't say why this occures, because we do not know what type of device it is. Sometimes it is a carridge return or something other that the server excpects. Maybe you could analyze the traffic (e.g. with the "Package Capture" App) once? Then we can see what is different to calls that are working.
kind regards,
Urs

Re: HTTP POST requests
I used Packet Capture and sent the HTTP POST request. The file is found but it's the wrong content type, "text/plain" when it should be "application/json". Is it possible to include the header "content-type:application/json" and if so, how?
From an app that successfully sends the command:
POST /jsonrpc HTTP/1.1
Content-Type: application/json
...
It returns:
HTTP/1.1 200 OK
...
From IR Control:
POST /jsonrpc HTTP/1.1
Content-Type: text/plain
...
It returns:
HTTP/1.1 415 Unsupported Media Type
...

Re: HTTP POST requests
Hi
Unfortunately it is actually not possible to change the content type. It is fix "text/plain". We will implement the possibility to give the content type as a new feature for HTTP requests in the next release.

Urs
