#28

@mstormi

If I follow the logic of MAP and JSONPATH it should be as follows:

Binding MAP JSONPATH REGEX
http1 MAP(onoff.map) JSONPATH($.value) REGEX(. ?(. ?).*)
http2 MAP:onoff.map JSONPATH:$.value REGEX:. ?(. ?).*

.
Did you also try REGEX:. ?(. ?).*

#29

I have updated the link above. If you set org.openhab.binding.http.internal.http to TRACE you’ll see the URL when requesting and the responses received.

#30

Dowloaded it but did that change anything about http logging ?
That’s not really useful yet. Would need to see Headers, body and reponse code of the request

#31

I‘ll see how I can improve that.

#32

Please check if the updated jar works for you.

#33

It does, thanks.
It helped me find my own error now that I see the 200 response.
Turned out it was the request I didn’t copy properly. That device needs to have http://host/yaddayadda&usr=username&pwd=password rather than basic auth.

What’s left is that apparently I must be having another HTTP thing active (resulting from first tests yesterday ?) as I keep seeing both URLs below (the difference is the additional ‘/’). I don’t find that 2nd one in the list of smarthome:things though - is it something your binding does ? (although I don’t think so as it has a different request interval).

But that reminds me of this: if I’m not mistaken, you add State and Command URL Extension to Base URL but insert a fixed ‘/’, correct?
Then please remove that fixed ‘/’ insertion as the requirement could as well be to continue the URL with ? or & like in my test case.

@J-N-K

Same here. I also need no fixed slash / at the end of baseURL or beginning of Extension. Many extensions will begin with ? or &.

#35

I have the changed the concatenation logic. It now first checks if either the last character of the baseURL or the first character of the extension is ?, / or & and adds the / only if nothing is present. jar updated

What seems not to be working yet is updating the item.

I’ve filled State Transformation with a REGEX to extract a value from one of the lines in the HTTP reponse body above: REGEX:.*?<motionDetectAlarm>(.*?)</motionDetectAlarm>.*

… but I don’t see the linked item update and no hint in the internal.http trace.

I enabled debug logging on org.openhab.transform.regex and it says it is to execute the transformation, but the output isn’t shown in log and the item isn’t updated.

</CGI_Result>

I tried both, Number and String items but no luck.
Any idea how to debug that further ?

Works perfectly for me:

Did you install the regex transformation?

#38

I have been using that with the v1 binding and my log above (“about to transform”) shows it’s applied, doesn’t it.
Do I need to use a Number or a String item ?

#39

I used a number item and pasted your transformation in the stateTransformation.

#40

Alright, it was my own silly fault. It has been working all the time but the value didn’t change so the item didn’t.
Everything alright with your binding - thanks.

I’ve tested it. It’s working. :slight_smile:

#42

How do I define multiple header entries?

Like:
Accept=application/json,X-Access-Token=MYTOKEN

#43

PaperUI? Just add a second entry. It automatically does that.

#44

OK, got it.

Another question: I’m trying to send a JSON string as the payload:

{'frames':[{'text':'TEST1','icon': 'a36755','index': '0'}]}

but then I’m getting:

It seems the content is messed up. What did you configure?

Is there a typo? The h at the beginning is missing?
