I'm working on a solar plant management app. Everything works fine so far. But now I have to connect the app with the webbox of the plant via the internet. The webbox provides a server which could be accessed by http requests, encoded in JSON format. I'm totally new to the JSON subject and don't know how to construct the correct SendHTTPRequest in AGK.

The official call to request basic plant data is following JSON object (regarding webbox manufacturer documentation):



I also have the IP address of the plant and the folder to send the request:

It's something like: http://IPaddress/rpc

I tried different ways of writing the data into the POST field of the SendHTTPRequest function, but without any success. Actually no error message from the server too. Just an empty result string, instead of any plant data.

EDIT: Don't know, but it's may be basically not possible to send a JSON "object" with the SendHTTPRequest? May be I should send the raw data to an PHP file and make the request from there on? If yes, how to do that?

Hope one of you guys could help me out.
Thanks a lot in advance!

hmm, i would say its this

chr(34) = "

json$="RPC={"+chr(34)+"version"+chr(34)+": "+chr(34)+"1.0"+chr(34)+","+chr(34)+"proc"+chr(34)+": "+chr(34)+"GetPlantOverview"+chr(34)+","+chr(34)+"id"+chr(34)+": "+chr(34)+"1"+chr(34)+","+chr(34)+"format"+chr(34)+": "+chr(34)+"JSON"+chr(34)+"+chr(34)+"}"

SendHTTPRequest("IP","rpc",json$)

@Markus: Thanks, but that's not working too, unfortunately. No result from Server back....

You may need to URL-encode the JSON, the HTTP protocol might not be happy with all the special characters in it.

Also note that the "RPC=" is not part of the JSON - that's a key that will contain the JSON data in the HTTP request.



You could also try sending it via GET rather than post, though POST seems like the better option:
