Idiom #101 Load from HTTP GET request into a string

Make an HTTP request with method GET to the URL u, then store the body of the response in the string s.

require 'net/http'
u = URI("http://example.com/index.html")
s = Net::HTTP.get_response(u).body

s = await client.GetStringAsync(u);

if err != nil {
	return err
}
buffer, err := io.ReadAll(res.Body)
res.Body.Close()
if err != nil {
	return err
}
s := string(buffer)
String s = u.text
const res = await fetch(u)
s = await res.text()
