Häufige Annahme

A bare numeric address like "8080" configures listening port 8080, and URI schemes like "tcp://localhost:2019" parse as standard TCP addresses.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• caddy.ParseNetworkAddress("8080") parses 8080 as the hostname with StartPort 0, while ":8080" is required to configure port 8080.
• caddy.ParseNetworkAddress("tcp://localhost:2019") splits on the first slash and sets Network to "tcp:" with a trailing colon and Host to "/localhost".
• caddy.ParseNetworkAddress("unix/data/socket.sock") sets Network to "unix" and Host to "data/socket.sock" with IsUnixNetwork true and StartPort 0.
• caddy.ParseNetworkAddress("localhost:8080-8085") parses a contiguous port range where StartPort is 8080, EndPort is 8085, and PortRangeSize is 6.
• caddy.ParseNetworkAddress("localhost:8085-8080") fails with "end port must not be less than start port".
• caddy.ParseNetworkAddress("localhost:99999") fails with a port value out of range error.
• caddy.ParseNetworkAddressWithDefaults("localhost", "tcp", 2019) applies the default port to return host "localhost" with StartPort 2019.
