[OH3] HowTo perform sendHttpGetRequest and sendHttpPutRequest in order to read/write through REST API

Setup, Configuration and Use Scripts & Rules
21

I searched for how to send requests to OH3 with API tokens in Jython/Python and found this thread, but no immediate answer on how to do it in Python.

It’s quite easy to deduct it from how @ariela ist doing it in JS.
Nevertheless here is an example, as it might be helpful for someone else:

from core.actions import HTTP

api_token = "oh.name.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
auth_headers = {
    "Authorization": "Bearer {}".format(api_token),
    "WWW-Authenticate": "Basic",
}

HTTP.sendHttpPutRequest(
    "http://my-oh.local/rest/things/max:bridge:IEQ0547745/config", # your OH domain & path in the REST-API
    "application/json",
    "{action-cubeReboot:1234}",
    auth_headers, # here is where the auth-info is handed over to the HTTP action
    9000) # a timeout value

Does anyone know how this works with a hosted private OH3 cloud service with Alexa, the Alexa API makes a request but gets the HTTP error

 - onComplete: 2030
21:22:55.104 [DEBUG] [.io.openhabcloud.internal.CloudClient] - Jetty request 2030 failed: HTTP protocol violation: Authentication challenge without WWW-Authenticate header
21:22:55.104 [DEBUG] [.io.openhabcloud.internal.CloudClient] - Response Failure: HTTP protocol violation: Authentication challenge without WWW-Authenticate header

Basic Auth is turned on, but the Alexa skill integrates using OAUTH, so I figured i just needed a matching username on OH3 (same as the OH3 Cloud or the Alexa skill) - still no joy

I’m having trouble getting this to work with OH 3.2. I have the same code above but it’s NOT re-enabling a few THINGs that are disabled. Am I missing something?

val 	headers = newHashMap("Authorization" -> "Bearer oh.RESTAPI.PrhuIqPGkhU8Sxy8DbXcQgMtYezcUR7yNWwmpnpehS25MV7akeDcFzr6Qf11mPsKmTFBDi49hZ9uf9kXXXX", "WWW-Authenticate"-> "Basic")

sendHttpPutRequest("http://127.0.0.1:8080/rest/things/sonos:CONNECTAMP:RINCON_XXXXFDE1B88801400/enable", "application/json", 'true', headers, 1000)				// Enable SonosThingOnWall
  Thread::sleep(500)  
sendHttpPutRequest("http://127.0.0.1:8080/rest/things/sonos:CONNECTAMP:RINCON_XXXXFDEA6E1E01400/enable", "application/json", 'true', headers, 1000)				// Enable SonosThingGround

what does the log say?

Here’s my logger for HTTP but I’m not seeing any errors. Am I missing something OR should I just put INFO status on a specific logger?

		<!-- HTTP -->		
		
		<Logger additivity="false" level="WARN" name="org.openhab.core.model.script.actions.HTTP">		
			<AppenderRef ref="HTTP"/>
		</Logger>			
	
		<Logger additivity="false" level="WARN" name="java.util.concurrent.ExecutionException">		
			<AppenderRef ref="HTTP"/>
		</Logger>		
		
		<Logger additivity="false" level="WARN" name="java.util.concurrent.TimeoutException">		
			<AppenderRef ref="HTTP"/>
		</Logger>	

		<Logger additivity="false" level="WARN" name="org.openhab.core.io.http">		
			<AppenderRef ref="HTTP"/>
		</Logger>	

		<Logger additivity="false" level="WARN" name="org.openhab.core.io.http.auth">

sorry, I meant openhab events and openhab log

Nothing is shown for the sendHttpPutRequest’s in those logs.

Can’t say if it makes a difference, however I’m creating my headers like:

var headers = [];
headers["Authorization"] = "Bearer oh.RESTCall.xyz123";
headers["WWW-Authenticate"] =  "Basic";

I do see no difference beside that. Using this sendHttpPutRequest you should get a returned value, log the contents of that one and post it here.

Finally found the issue, it was the MIME type.

Examples on the forum showed “application/json” which worked for OH2.x.

I switched it to → “text/plain”

Now it’s working perfectly!
