Extends Request with lookup of DNS SRV records.
Use just as you would Request except that instead of the hostname in the URI you use the SRV record host. A random host will be chosen from the SRV results.
Given the following example setup created using SkyDNS and Registrator:
root@server1:~# dig SRV myservice.skydns.local
...
;; QUESTION SECTION:
;myservice.skydns.local. IN SRV
;; ANSWER SECTION:
myservice.skydns.local. 33 IN SRV 10 100 8110 server1-myservice-8000.myservice.skydns.local.
myservice.skydns.local. 33 IN SRV 10 100 8110 server2-myservice-8000.myservice.skydns.local.
;; ADDITIONAL SECTION:
server1-myservice-8000.myservice.skydns.local. 33 IN A 10.10.10.30
server2-myservice-8000.myservice.skydns.local. 33 IN A 10.10.10.40
...You will make your request as such:
var request = require('srv-request');
request('http://myservice.skydns.local/v1/ping', function (error, response, body) {
console.log(error, body)
});The HTTP requests will then be made to the URI: http://server1-myservice-8000.myservice.skydns.local:8110/v1/ping.
