JSON POST http request

[Cafun 13]

Hi community!

I was hoping someone can help me out with something.

 

So, I got

to open/close my curtains.

They've got an OpenAPI. At this moment there is no integration Fibaro (but they say it will be). I also do have Home Assistant and with that I can control my curtains.

I know it's not ideal, but I would like to use the Home Assistant API to open/close my curtains. So when I press a button on a Zwave remote, it opens/closes my curtains.

 

I don''t have any knowledge about JSON and http requests into Lua. I have the code below, but it doesn't work (I didn't expected to ).

At this moment it I get the error: 

[ERROR] 07:22:13: line 3: '' expected near '" "'

But I don't think it's the only thing which isn't right.

They payload I defined should be in the body.

Hi @Cafun,

 

not really an answer to your question, but I'm working already on integration of Slide, but it's delayed a bit because my Slide is currently @ IIM to be revised/repaired, but i hope to continue soon with testing and will share it soon here as well to IIM so they can provide it on their support site

See below attached screenshot of Slide VD:

 

As soon as i receive my Slide back (hopefully this week) I will continue development and testing, so i hope to finish it very soon.

Ah cool! Thanks for the response! Hopefully you can soon continue with testing. If you want me to test anything, I will be happy to.

 

In the mean time, I hope someone can help me with the problem.

I'm not sure if I can help you, but

try ' instead of " at the beginning and the end; then a " inside is handled as a real character

I suppose ...= '{ entity_id: "cover.raam_voor" }'

 

have a look at

good luck!

Hi muc, thank you for your reply.

I would try your suggestion, but it appears I'm stuck at row 1:

 

[ERROR] 09:05:43: line 1: attempt to index global 'net' (a nil value)

 

I'll dig a little deeper.

If anyone has suggestions, I'm open to it.

Thanks.

 

Edit:

I guess it needs to be a scene instead of a virtual device to call the 'net.HTTPClient()' command.

But now I get the following error:

 

[DEBUG] 11:05:52: 2019-12-15 11:05:52.306106 [ fatal] Unknown exception: /opt/fibaro/scenes/262.lua:21: attempt to index global 'ltn12' (a nil value)

 

I'm going to lookup some other examples, hopefully I get it working.

 

@Bodyart

I hope you've got your slide back already?

Hi @Cafun,

yes it came on Friday, but currently there is something wrong with the API, so i didn't make much progress and will contact the "Slide guys" on monday to solve the issue..

[rickydehaas 4]

@Bodyart thanks for your effort! Planning to buy slide when integration is succesfull.

[Cafun 13]

No one can help me with the JSON code?

@Bodyart It's great to hear that you are working on integration. Will the end result still be a VD? If so, I'll need to find a voice control work around.

Hi @Blackdog65,

it will be 1 VD per Slide with one scene for all Slides.
Just solved a nasty bug with help of @Sankotronic, so i hope to finish it soon (January)

Nice! Can't wait to integrate it in Fibaro

Hi @Cafun,

 

i'm doing my best

[Cafun 13]

Sure! Many thanks!

Hi @Cafun,

 

if you want to do something with JSON in LUA/Fibaro you need to use the json.encode/json.decode libraries in LUA. What you can typically do is already list your datamodel in JSON (see authData below) so you can make it visual for yourself what your data will look like and how you can access it. Especially with multi dimension tables it helps to visualise how you can call your data, e.g. below you will have tables in tables ('slides' is a table, but the entry 'slide1' is also a table). So you have tables within tables and by visualising this upfront it helps you in your encoding/decoding endeavours

Since I was looking into

as well hereby a snippet of a way in which I'm able to get a Token (and do other calls to their platform using that token).  I've included a small loop that shows you how you can access data in a table. The call towards the slide api contains JSON encode data (username and password) and since the data you'll get back is also a JSON it also includes a way to read the JSON response by decoding it.

Hopes this helps to get JSON up and running in LUA!

[Cafun 13]

@gabordewit Thnx! I'm going to try it!

@gabordewit I have downloaded the scene/vib from your github. When I want to initialize the slides I get the error below. Hope you can help me with this:

[DEBUG] 09:37:56: 2020-03-06 09:37:56.774388 [ fatal] Unknown exception: /opt/fibaro/scenes/264.lua:54: '=' expected near ','

@Cafun  Can you paste your scene block here so I can have a look at the line that is giving the error?

 

You did make me realise I had a function in there called debuglogger that i've just replace for fibaro:debug (editted above), however if I run the code standalone now in a scene it seems to reply from the SLIDE API.

[Cafun 13]

I've used the code and virtual device from your github. Here is my scene:

@Cafun Apologies for not getting back sooner.

 

The reason why line 54 is generating an error is due to the fact that code that should be commented out is actually visible (see red below):

Please login or register to see this code.

If you change the red to --[[ or put slides = {} (and remove everything that is now in between the { } under slides you should be good to go. I've updated the api itself a bit recently, there is now also a 1.0.1 available.

[Cafun 13]

Oh damn, I didn't got a notification you replied! I'll try it. Thanks!

And where can I find the 1.0.1? It's not on your github?

 

Edit: It works! Thanks, Now I can do some detailed programming for the curtains  (normally I let it open and close at sunrise and sunset, but now that's not sufficient anymore).

If I can get your updated code, I would be happy to.

It's working great, thank you!

Are you still developing some things for it? Just curious
