I’d like to lookup a DNS TXT record in a rule. The rules docs suggest the dns module is available, and I can require it without error.
However, when I try to call dns.resolveTxt
my callback is never called.
Here’s a simple case that doesn’t work - can anyone spot what I’m doing wrong?
function (user, context, callback) {
var dns = require('dns');
var hostname = "google.com";
console.log("hostname", hostname);
dns.resolveTxt(hostname, function(err, result) {
console.log("result", err, result, JSON.stringify(result));
});
return callback(null, user, context);
}
Ergh, this was just my javascript inexperience. Of course, the callback must be inside the dns lookup. Like this:
function (user, context, callback) {
var dns = require('dns');
var hostname = "google.com";
console.log("hostname", hostname);
dns.resolveTxt(hostname, function(err, result) {
console.log("result", err, result, JSON.stringify(result));
return callback(null, user, context);
});
}
