Try this, change key_id/key_secret as needed. request function accepts two parameters - request URI (starting with /v1/api/...) and request body (either a table which is converted to JSON or a string which is sent as is).
The calculated signature differs from documented example even though it is calculated the same way. Might be an error in the documentation.
Code:
require('json')
require('encdec')
require('socket.http')
require('ltn12')
host = 'https://www.soliscloud.com:13333'
key_id = '2424'
key_secret = '6680182547'
function request(uri, body)
local method = 'POST'
if type(body) ~= 'string' then
body = json.encode(body)
end
local content_md5 = encdec.md5(body, true)
content_md5 = encdec.base64enc(content_md5)
local content_type = 'application/json'
local date = os.date('!%a, %d %b %Y %X GMT')
local sign = method .. '\n' ..
content_md5 .. '\n' ..
content_type .. '\n' ..
date .. '\n' ..
uri
sign = encdec.hmacsha1(sign, key_secret, true)
local url = host .. uri
local auth = 'API ' .. key_id .. ':' .. encdec.base64enc(sign)
local headers = {
['Content-MD5'] = content_md5,
['Content-Type'] = content_type,
['Date'] = date,
['Authorization'] = auth,
['Content-Length'] = #body,
}
local resp = {}
local res, code = socket.http.request({
url = url,
method = method,
source = ltn12.source.string(body),
sink = ltn12.sink.table(resp),
headers = headers
})
if res and code == 200 then
return table.concat(resp)
else
return nil, code
end
end
res, err = request('/v1/api/userStationList', { userId = '1145611319416590338' })
log(res, err)
