Overview ¶
Package plugin provides plugin register interfaces for building http handler plugins.
Usage example:
package main import ( "context" "errors" "fmt" "html" "net/http" ) // HandlerRegisterer is the symbol the plugin loader will try to load. It must implement the Registerer interface var HandlerRegisterer = registerer("lura-example") type registerer string func (r registerer) RegisterHandlers(f func( name string, handler func(context.Context, map[string]interface{}, http.Handler) (http.Handler, error), )) { f(string(r), r.registerHandlers) } func (r registerer) registerHandlers(ctx context.Context, extra map[string]interface{}, _ http.Handler) (http.Handler, error) { // check the passed configuration and initialize the plugin name, ok := extra["name"].(string) if !ok { return nil, errors.New("wrong config") } if name != string(r) { return nil, fmt.Errorf("unknown register %s", name) } // return the actual handler wrapping or your custom logic so it can be used as a replacement for the default http handler return http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) { fmt.Fprintf(w, "Hello, %q", html.EscapeString(req.URL.Path)) }), nil } func init() { fmt.Println("lura-example handler plugin loaded!!!") } func main() {}
