How to get external ip address

[jlmess77]

You can use IP-API.com to get it by x.json2 module. Check the documents at https://ip-api.com/docs/api:json and https://modules.vlang.io/x.json2.html

The code needs to be updated to use ! otherwise use or {} instead of ? .

I was a little bored and learning at the same time. Here's what I wrote:

module main

import x.json2
import net.http

struct GetIp {
	query string
}

fn main() {
	url := http.get('http://ip-api.com/json/') or {
		println('Failed to fetch JSON from ip-api.com.')
		return
	}

	ip_response := json2.decode[GetIp](url.body) or {
		println('Failed to decode JSON response.')
		return
	}

	println(ip_response.query)
}
