How to get the return value from a external rest service using SSJS

Question

How to call external rest service using SSJS not using java code. I would like to call an external URL and then it returns a value, how to capture this value.

Answer 1

Do you want something a little like this:

var url:java.net.URL = new java.net.URL("https://www.google.com");
var conn:javax.net.ssl.HttpURLConnection = url.openConnection();

conn.setRequestMethod("GET");
conn.setRequestProperty("Content-Type", "text/html");

if(conn.getResponseCode() == 200) {
    var strReturn;
    var strOutput;
    var br:java.io.BufferedReader = new java.io.BufferedReader(new java.io.InputStreamReader(conn.getInputStream()));
    while((strOutput = br.readLine()) != null) {
        strReturn += strOutput;
    }
    conn.disconnect();
    return strReturn;

} else {
    conn.disconnect();
    return "URL failure: " + conn.getResponseCode();
}
