Häufige Annahme

json.Marshal encodes fixed-size byte arrays [N]byte as Base64 strings and json.Unmarshal decodes Base64 strings into byte arrays.

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

• assert json.Marshal encodes fixed-size byte array [N]byte as a JSON numeric array instead of a base64 string
• assert json.Unmarshal of a base64 string into [N]byte fails with UnmarshalTypeError
• assert json.Unmarshal of a JSON numeric array into [N]byte succeeds
• assert json.Marshal encodes byte slice []byte as a base64 string
• assert json.Unmarshal of a base64 string into []byte succeeds
• assert json.Unmarshal of a JSON numeric array into []byte succeeds
• assert json.Marshal encodes signed byte slice []int8 as a numeric array
