Invoke Rest api end point in LUA

Question

I need to invoke a Rest API endpoint from my Lua script. How can I do that? For example, I am able to invoke the endpoint by the below curl command:

curl -X GET \
  -H "X-Parse-Application-Id: ParseAppID" \
  -H "X-Parse-REST-API-Key: RESTAPIKey" \
  https://api.parse.com/1/classes/GameScore

The same I wanted in Lua.

I'm using [Lua-cURL](https://github.com/Lua-cURL/Lua-cURLv3) for this. — csaar, Nov 14 '19 at 07:30

You have lots of options

All of them are slightly different, but all of them can call your API endpoint.

Lua by itself cannot call that endpoint, since the standard networking doesn't support https. You will need to use a 3rd-party library, I suggest Lua-cURL. You will need to download and install it.

Using luasocket:

local http = require('socket.http')
local ltn12 = require('ltn12')

local r = {}
http.request {
    url = 'https://blockchain.info/tobtc?currency=USD&value=1000000',
    headers = {['x-accept'] = 'donates'},
    sink = ltn12.sink.table(r)
}
print(r[1])

Please note that many versions of luasocket (including 3.0-rc1 in Debian Bullseye) [silently downgrades https to http](https://stackoverflow.com/questions/37555226/luasocket-http-requests-always-respond-with-a-redirect-301-or-302). Fixed in 3.0.0 proper according to [MSGH#229](https://github.com/lunarmodules/luasocket/issues/229). – sampi Oct 11 '22 at 12:41
