Allows for Consul Service Lookup over HTTP
This module requests all passing consul services with the desired name, and
optional version tag, and returns the URL of a randomly selected copy of the service.
Example:
<?php
// Passing `null` as the first argument lets the module create it's own http client
$serviceLookup = new CascadeEnergy\ServiceDiscovery\Consul\ConsulHttp(null,"<ip-of-consul-server>:8500");
// `service-version` is optional
$serviceUrl = $serviceLookup->getServiceAddress(<service-name>, <service-version>);
if ($serviceUrl == null) {
//If no healthy instances of the desired service are found, the url returned is `null`
//this can be handled in any convenient manner such as:
throw new Exception('Service not found!');
} else {
//The service was found!
$client = new <insert-your-favorite-http-client-here>();
$request = $client->put("$url/<route>",null,<body>);
// keep interacting with the service, ask for urls of new services, etc...
}
