Python

Die folgenden Beispiele wurden mit Python 3 getestet. Um sich bei Pathfinder Server zu authentifizieren, müssen Sie einen API-Schlüssel verwenden.

1 Verbindungstest mit PFS (authentifizierte und nicht authentifizierte Endpunkte)
2 Anzeige der Netzwege zu einem Port

Beispielausgabe:

Call without authorization...
OK
Call with authorization...
