Weather info yr.no new API

[AlexLV]

Hi,

service yr.no now use new API and advice use .json format for weather data reading. .xml will not supported anymore from start of the next year.

Info here: https://developer.yr.no/doc/

May be some created script based on .json and new API?

I just tried to read data for me and receive error:

link to info with .json:          https://api.met.no/weatherapi/locationfo...ltitude=13


Script I tried to read data:

Code:

require('json') https = require('ssl.https') escape = require('socket.url').escape url = 'https://api.met.no/weatherapi/locationforecast/2.0/complete?lat=67.8596&lon=35.0904&altitude=13' url = string.format(url) res = https.request(url) log(res) data = json.pdecode(res) log(data) if type(data) ~= 'table' then   alert('failed to load weather data')   return end if data.error then   log('error', data.error)   return end

I received such error:

* string: 403 Forbidden

User-Agent header LuaSocket 2.0.2 is not allowed, use a unique identifier

What is incorrect in my trying?

BR,

Alex

i tried it got the same error, looking at the documents it say "that you must send a unique identifier in the User-Agent header. Any requests with a prohibited or missing User-Agent will receive a 403 Forbidden error."

i don't know how to pass the headers with socket.url but i tried it with http.request, like the below with the User-Agent header, it returns the data

Code:

function get_request(url)   local http, ltn12, sink, res, err   ltn12 = require('ltn12')   http = require('socket.http')     sink = {}   res, err = http.request({       url = url,       method = 'GET',       headers =     {       ["Accept"] = "*/*",       ["User-Agent"] = "1234567897",  -- i think this can be any number?     },     sink = ltn12.sink.table(sink)   })   if sink then        return table.concat(sink)   else     return nil, err   end end x = get_request('https://api.met.no/weatherapi/locationforecast/2.0/complete?lat=67.8596&lon=35.0904&altitude=13') log(x)

You can override default user agent like this. This example uses LM MAC address to create a unique number for the user agent string.

Code:

json = require('json') http = require('socket.http') url = 'https://api.met.no/weatherapi/locationforecast/2.0/complete?lat=67.8596&lon=35.0904&altitude=13' mac = 0 io.readfile('/sys/class/net/eth0/address'):gsub('%x%x', function(v)   mac = mac * 256 + tonumber(v, 16) end) http.USERAGENT = 'LM ' .. mac res, err = http.request(url) log(res, err)
