json POST syntax

[747 12]

Hi,

 

Im trying to control a Danalock through a Danabridge and so far i can get the token and use it to retrieve my locks and its status but when trying to perform lock/unlock i get a 404 error.

I have translated a python implementation but this last part is not working.

 

The encoded json from python looks like this:

payload = json.dumps({"device": serial, "operation": "afi.lock.operate", "arguments": [command]})

The command here is either "lock" or "unlock" but since its inside brackets im not sure how to translate it.

"arguments": ["lock"] and "arguments": "[lock]" doesnt work.

 

Does anyone have an idea how the syntax should be?

 

My POST in lua looks like this:

http:request('https://bridge.danalockservices.com/bridge/v1/execute',{
    options = {
      method = 'POST',
      headers = {
        ['Accept'] = 'application/json',
        ['Content-Type'] = 'application/json',
        ['Authorization'] = 'Bearer ' ..token          
      },
        data = json.encode({
        ["device"] = lockserial,
        ["operation"] = "afi.lock.operate",
        ["arguments"] = '["lock"]'
          })
  },

Try arguments as LUA array

 

["arguments"] = {"lock"}

Thanks ivx, but it seems i still get a 404..

HTTP error 404 means URL(https://bridge.danalockservices.com/bridge/v1/execute) does not exist and seems not related to arguments values.

Just try to get locks list, can you see lock in list and serial is as you set.

 

 url = "https://api.danalock.com/locks/v1"
 r = requests.get(url, headers={'Authorization': 'Bearer ' + token, 'Accept': 'application/json', 'content-type': 'application/json'})

But as soon as i try to lock it i get the 404 (And sometimes i have seen 500 also)

Try to get state pf lock

 

execute_url = "https://bridge.danalockservices.com/bridge/v1/execute"

    payload = json.dumps({"device": serial, "operation": "afi.lock.get-state"})

    r = requests.post(execute_url, headers={'Authorization': 'Bearer ' + token, 'Accept': 'application/json', 'content-type': 'application/json'}, data=payload)
 

If it's arguments problem - .get-state doesn't have array arguments, so does this work ?

[747 12]

Yes, "afi.lock.get-state" works

[ivx 3]

use print() out json.encode() and post here.

[747 12]

{"operation":"afi.lock.operate","arguments":["lock"],"device":"XX:XX:XX:XX:XX:XX"}

[ivx 3]

Seems ok, but does remote server check arguments order - which is not same.

Try pass raw string(without json.encode)

'{"device":"XX:XX:XX:XX:XX:XX","operation":"afi.lock.operate","arguments":["lock"]}'

Now i got a 500 instead.. (internal error)

After some re-tests, i still get 404

[ivx 3]

Now syntax is right, can't suggest more. Only you can try

 , with this you can see raw 404 response, sometimes i have got more info from there.

 

You can get token and print it out from current code. Just make

Ill try your suggestion to see if i can figure out what is wrong.

Weird, when using the API tester then it works..

[ivx 3]

Copy paste reqbin json, but between single quotes ' ', try post raw string again.

If doesn't work, then there must be some headers difference. 

[Joep 197]

or you need to encode the json payload if it has special chars in it.

[ivx 3]

Yep. reqbin raw shows you exactly what data it sends to remote server ...

 

One difference is that it doesn't send Accepts header.

Sorry, what do you mean by reqbin?

[ivx 3]

I meant reqbin.com REST API tester.

 

Also how you get token and call

Fibaro HTTP calls are asynchronous and execute in background.

Without seeing code, are code free of racing condition ?

Make call to get token

   - starts executing

Now you make call to control lock, but get-token http request still executing(no token yet)
