client IP

[5nyper]

How do I go about getting the visitors IP?

[mrtryhard]

Something along the lines of : headers["REMOTE_ADDR"]

Note that if this returns nil, you should probably try something like
headers["HTTP_X_FORWARDED_FOR"]

This is a raw way of doing things and I didn't test it either. Also, do not forget that IP addresses can easily be spoofed and are not reliable :-(

Maybe the author can offer a better detailed example. I haven't used the framework yet :^)

There's currently no better way than what mrtryhard suggested. EDIT: headers is a property of a Moonshine::Request object eg.

    app.route "/", do |req|
        ip = req.headers["REMOTE_ADDR"]
        ok("#{ip}")
    end

Note that this will raise an exception if the client doesn't send the REMOTE_ADDR header

[mrtryhard]

Thanks for the example! Does it raise an exception because the key isn't found in headers?

[5nyper]

Yeah both REMOTE_ADDR and HTTP_FORWARDED dont work :(

[dhruvrajvanshi]

You can try printing out the request headers to see if any ip is found there. Otherwise, you're out of luck. It is up to the client (browser) and the proxy servers between client and server to set(or unset) the REMOTE_ADDR header. Which browser are you using? A better way to identify clients is to use session cookies. Hopefully, I will be able to add session handling soon.
