http post request issues - stork - 09.06.2023
I'm trying to send energy data through an API by using http.request:
Code:
local dateTime=os.date("%Y-%m-%dT%H:%M")
local http = require("socket.http")
local ltn12 = require("ltn12")
local data = grp.getvalue('360_001_OE001 - Heat energy E1')
body = [[{
"meterID": "0501e479-2a12-45b4-8cb6-505ced85428f",
"values": ["]]..dateTime..[[,]]..data..[[]
}]]
local response_body = {}
res, code, headers, status = http.request{
url = "https://www.energinet.net/apiImport/data",
method = "POST",
headers ={
["Authorization"] = "Bearer xxxxx",
["Content-Type"] = "application/json",
["Accept"] = "application/json"
},
source = ltn12.source.string(body),
sink = ltn12.sink.table(response_body)
}
log(response_body)
log(body)
log(res,code,headers,status)log(res,code,headers, status) returns:
* arg: 1 * nil * arg: 2 * string: Try again * arg: 3 * nil * arg: 4 * nil
response_body is empty.
Headers are as specified by the API-provider.
Any ideas what might be wrong? Hiow should I understand the "Try again" from log(code)?

Check that gateway and DNS settings are valid in System config > Network > Interfaces > eth0.

They should be. The LM5 is online.

I think your body is not a valid json format, you are missing a " in the values property

Thanks for the replies. You are right, I saw that one, but had to add another DNS to be able to communicate. Also I had to add content-length even if it was not specified by the API-provider. Thanks for notifying me about DNS-settings, which was part of the problem.
