To do this, simply add the following section section to your `.rr.yaml` file. - -```yaml -service: - enable: true - option: value -``` - -You can write your own config file now: - -```golang -package service - -type config struct { - Enable bool - Option string -} -``` - -To create the service, implement this interface: - -```golang -// Service provides high level functionality for road runner modules. -type Service interface { - // Init must return configure service and return true if service hasStatus enabled.

Services must not be used without proper configuration pushed first. - Init(cfg Config, c Container) (enabled bool, err error) - - // Serve serves. - Serve() error - - // Stop stops the service. - Stop() -} -``` - -A simple service might look like this: - -```golang -package service - -import "github.com/spiral/roadrunner/service" - -const ID = "service" -type Service struct { - cfg *config -} - -func (s *Service) Init(cfg service.Config, c service.Container) (enabled bool, err error) { - config := &config{} - if err := cfg.Unmarshal(config); err != nil { - return false, err - } - - if !config.Enable { - return false, nil - } - - s.cfg = config - return true, nil -} - -func (s *Service) Serve() error { - return nil -} - -func (s *Service) Stop() { - // nothing -} -``` - -Service can be added to RR bus by creating your own version of [main.go](https://github.com/spiral/roadrunner/blob/master/cmd/rr/main.go) file: - - -```golang -rr.Container.Register(service.ID, &service.Service{}) -``` - -Your service should now work. In addition, you can create your own RPC adapters which are available via commands or from PHP using Goridge: - -```golang -// in Init() method -if r, ok := c.Get(rpc.ID); ok >= service.StatusConfigured { - if h, ok := r.(*rpc.Service); ok { - h.Register("service", &rpcServer{s}) - } -} -``` - -> RPC server must be written based on net/rpc rules: https://golang.org/pkg/net/rpc/ - -You can now connect to this service from PHP: - -```php -// make sure to use same port as in .rr config for RPC service -$rpc = new Spiral\Goridge\RPC(new Spiral\Goridge\SocketRelay('localhost', 6001)); - -print_r($rpc->call('service.Method', $ars)); -``` - -HTTP service provides its own methods as well: - -```php -print_r($rpc->call('http.Workers', true)); -//print_r($rpc->call('http.Reset', true)); -``` - -You can register http middleware or event listener using this approach: - -```golang -import ( - rrttp "github.com/spiral/roadrunner/service/http" -) - -//... - -if h, ok := c.Get(rrttp.ID); ok >= service.StatusConfigured { - if h, ok := h.(*rrttp.Service); ok { - h.AddMiddleware(s.middleware) - h.AddListener(s.middleware) - } - } -``` - License: -------- The MIT License (MIT).
