How can I get results from Web-API queries without using JavaScript?

[-vSky-]

I've been trying to set up Spotify Web-API for use on my own site for 1 week, but I couldn't get any results. With the help of the document below, I created a simple query interface over nodeJS.

Authorization Code Flow | Spotify for Developers

You need a server to run nodeJS. I want to use it actively on my own site without the need for a server. It is said in the documents that it can be done with "/authorize" using the "GET" method.

This is how I set up the request to get the authorization results based on that.

https://accounts.spotify.com/authorize&Client_id&Client_Secret

After trying this I think spotify took pity on me and replied with an error warning telling me to go to the help section.

Now I'm asking the Spotify community, how can I use this Web-Api without using JavaScript?
