help with net.HTTPClient()

[JcBorgs 52]

Any experts on the net.HTTPClient() coding in here?

 

Am trying to build a QA for my car charger (Charge Amps HALO) and have access to the REST API. They have a bit different implementation to what I have worked with before, you need to login with email, password & APIkey to get a ”token” that you then use in other request. If I do this login on their swagger page I am able to get a token and then build a simple function to pull out information about my Charger, and this works just fine:

 

Code:

function QuickApp:GetData()

  http = net.HTTPClient()

    local url = "

d"

    local requestBody = '

d'

    local token 

="aabbccddeeffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz"

 

    http:request(url, 

          {

            options = {

                data = requestBody, 

                method = "GET",

                headers = {

                           ["accept"] = "application/json", 

                           ["Authorization"] = "Bearer " ..token

                           }

                       },

         success = function(response) 

                      print("response status: " ..response.status)

                      print("Response data: " ..response.data)

                    end

            })

end

[21.04.2022] [18:34:25] [DEBUG] [QUICKAPP977]: response status: 200

[21.04.2022] [18:34:25] [DEBUG] [QUICKAPP977]: Response data: [{"id":"XXXXXXXXXXXXXXX","name":"XXXXXXXXXXXX","password":"XXXXXXXXXX","type":"HALO","isLoadbalanced":true,"firmwareVersion":"72","hardwareVersion":"2","ocppVersion":null,"settings":null,"connectors":[{"chargePointId":"XXXXXXXXXX","connectorId":1,"type":"Charger","settings":null},{"chargePointId":"XXXXXXXXXXX","connectorId":2,"type":"Schuko","settings":null}]}]

 

So the above part are working just fine, sensitive information have above been replaced with bogus information. But the issue I have is that I want to do another ‘function’ that handles the login to get a token (there is a login “swagger”on the Charge Amps swagger page) that can be stored in the HC3 as a variable, the  “tokens" are only valid for 2 hours and need to be regenerated several times each day to keep the QA working.

 

To be able to do this you need to provide apiKey, email & password, but I can’t get that to work….. Doing it on the Charge Amps swagger page works just fine, but need this in a ‘function’ in the QA to be able to automate the collection of ‘token’ :

Curl from the Charge Amps swagger page>

Request URL from the Charge Amps swagger page>

Code I have tried:

function QuickApp:CAlogin()

 http = net.HTTPClient()

 local requestBody = 'https://eapi.charge.space/api/v4/chargepoints/owned'

 local APIkey = "xxzzyyxxzzyyxxzzyy=="

 

http:request("https://eapi.charge.space/api/v4/auth/[email protected]&password=aabbccddeeff",{

    options = {

               data = requestBody, 

               method = "POST",

               headers = {

                          ["Content-Type"] = "application/json",

                          ["accept"] = "*/*",

                          ["apiKey"] = APIkey

                          }

              },

              success = function(response) 

                        print("Status", response.status)

                        print("Data", response.data)

                        end,

              error = function(message)

                      print("error:", message)

                      end

                }) 

end

 

This simply doesn’t  work and just gives a 400 as status code in the Fibaro log. But how do I do a net.HTTPClient() request that includes apiKey, email and password as required by Charge Amps? Tried to put email and password in the URL but that does not seem to work. Have also tried to put it in other parts of the code but it simply doesn’t work, always gives me a 400 status code.

The updates version seem to work well!

 

One thing I noticed which differs from native ChargeAmp app is that after I change the "current limit" I must either turn it off or turn it on in the QA to have the "current limit" to be updated. Easy to compensate for by additional step in a scene. 

Yes, in the current design the change of current are only executed once the Charger is either turned ON or OFF.  Might change that in a future version.

Another observation, still manageable, but the names of the buttons trying to trigger them from a scene are the same, several buttons called ON, OFF, +, - etc.  Since I know in what order they are, it is not a problem.

Good observation! Haven’t thought about it since I didn’t think of using it from “outside” the QA.

This will be changed in a coming version, thanks for the feedback!

A new version will be published this week with support for the new Tibber Monitor QA. But in the future please refer to this thread for updates and questions about this Charge Amps QA:
