API, POST

[tomnord]

So, I've run into a wall on something as ease as a POST function to a API.
How do I format the request to get this to work?

Code:

123456789

curl --request POST \      --url https://api.easee.cloud/api/chargers/EH840488/settings \      --header 'Authorization: Bearer *****MY TOKEN*****' \      --header 'content-type: application/*+json' \      --data ' {      "dynamicChargerCurrent": 16 } '

Code:

12345678910111213141516171819202122232425262728

function WriteToEasee(request, request_body)   request_url = 'https://api.easee.cloud/api/' .. request   local response_body = {}   local request_body = ""   local body, code, hdrs, stat = ssl.https.request{     url = request_url;     method = "POST";     headers =     {       ["Content-Type"] = "application/json";       ["Authorization"] = "Bearer " .. API_Token;     };     source = ltn12.source.string(request_body);     sink = ltn12.sink.table(response_body);   }   log(code)   if code == 200 then     ret = table.concat(response_body)     ret = json.pdecode(ret)     return ret   else     --API_Token = GetToken() -- request a new token   end end dynCurr = 10 -- Dynamic current setting. WriteToEasee('chargers/' .. ChargerID  .. '/settings', "dynamicChargerCurrent" .. dynCurr)

This is as far as I've gotten. I'm getting code 400, request is missing or has invalid values.
I guess it's a small matter, but i have not worked with POST functions before.

Request is missing Content-Length header:

Code:

1

["Content-Length"] = #request_body,

["Content-Length"] = #request_body,

Still 400:

function WriteToEasee(request, request_body)   request_url = 'https://api.easee.cloud/api/' .. request     local response_body = {}   local content_length   if type(request_body) == "string" then     content_length = #request_body   else     request_body = ""   end   local body, code, hdrs, stat = ssl.https.request{     url = request_url;     method = "POST";     headers =     {       ["Content-Type"] = "application/json";       ["Authorization"] = "Bearer " ..

WriteToEasee('chargers/' .. ChargerID  .. '/settings', "dynamicChargerCurrent" .. dynCurr)

Could it be a mismatch with this?
WriteToEasee('chargers/' .. ChargerID  .. '/settings', "dynamicChargerCurrent" .. dynCurr)

In the docs it says this:  "{\"dynamicChargerCurrent\":16}"

You need to encode your request data using JSON:

Code:

12

body = require('json').encode({ dynamicChargerCurrent = dynCurr }) WriteToEasee('chargers/' .. ChargerID  .. '/settings', body)

BINGO, Thank You, as always
Only thing missing now is the response_body.. that one is blank.
