Help With Net And Api Request

Shyam

Hello, i am trying to wrap my head around how to use an api to get some kind of weather data as a test.
I ended up signing up on rapid api and i have this kind of curl request lines:
curl --request GET \
--url '[Login to see the link]' \
--header 'x-rapidapi-host: weatherapi-com.p.rapidapi.com' \
--header 'x-rapidapi-key: HIDDEN KEY'
How am i supposed to write the code in LuaRT to make it work and get some kind of intelligible data back?
Thanks in advance.

I have hidden your API Key. This kind of key should not be published publicly.
It's late for me I will answer you tomorrow

This code should work :

local net = require "net"

-- Create a client HTTP instance using the "https://weatherapi-com.p.rapidapi.com"
local client = net.Http("https://weatherapi-com.p.rapidapi.com")
client.headers["x-rapidapi-host"] = "https://weatherapi-com.p.rapidapi.com"
client.headers["x-rapidapi-key"] = "YOUR API KEY"

-- make a GET request, and after its terminated, call the provided function, to process the response
client:get("/current.json?q=53.1%2C-0.13").after =  function (self, response)
                                 if not response then
                                    error(net.error)
                                 end
                                 print(response.content)
                              end
-- be sure to wait for task to finish before exiting                             
waitall()

Thank you so much for taking the time for answering and hiding my API key. I tried your code snippets but unfortunatly i get this kind of result when printing response.content:
"Oops, an error in the gateway has occurred. If the issue persists, please contact [Login to see the link]"

Unfortunatly Have no idea what could it be the cause. I have zero knowledge about networking beyond some basic tutorial and was hoping to use LuaRT to do some learning. Probably should start from more basic stuff to understand what i am doing wrong.

Sorry to see it doesn't work. Maybe you should contact rapidapi support for more information about this error ?

Ok I have the problem on Rapidapi help.
You need to remove "https:\\" from the header field "x-rapidapi-host"

So this should work :

local net = require "net"

-- Create a client HTTP instance using the "https://weatherapi-com.p.rapidapi.com"
local client = net.Http("https://weatherapi-com.p.rapidapi.com")
client.headers["x-rapidapi-host"] = "weatherapi-com.p.rapidapi.com"
client.headers["x-rapidapi-key"] = "YOUR API KEY"

-- make a GET request, and after its terminated, call the provided function, to process the response
client:get("/current.json?q=53.1%2C-0.13").after =  function (self, response)
                                 if not response then
                                    error(net.error)
                                 end
                                 print(response.content)
                              end
-- be sure to wait for task to finish before exiting                             
waitall()

Now it is working, thank you so much. You was very helpful and i want to thank you again.

LuaRT is helping me a lot in learning new stuff and doing some fast scripting at my job that i would not have been able to do otherwise with the small amount of time i can allocate to self teaching programming while juggling a full time job.

The fact that you do this all for free is a reason more to be thankful. Hope one day to have the skill/time to contribute to this nice project of your.

If you happen to accept donations or have a patreon i would love to send you something as a token of my appreciation.

Also the other day while i was trying to wrap my head around this stuff i noticed that the Json.decode() method example doesn't run as written, but return the following error:"bad argument #1 to 'decode' (string expected, got Task)"

Wish you a good day Samir and hope to see even more nice stuff in the futures updates of LuaRT.

Samir

Glad to see it works !
Thank you for your positive feedback on LuaRT.

There is a koffee link on the LuaRT Twitter account if you want to support (it will pay the web hosting essentially for the website) :

PS: Thank you for the report for json.decode() example, it is now fixed
