Häufige Annahme

Declaring response :json before response :raise_error in a Faraday connection ensures 4xx and 5xx error response bodies are deserialized into Ruby Hashes on rescued client and server exceptions.

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

• Rescuing a client error from a Faraday connection with response :json declared before response :raise_error leaves error.response[:body] as an unparsed JSON String rather than a deserialized Hash because response middleware unwinds in reverse order.
• Declaring response :raise_error before response :json allows response :json to decode 4xx and 5xx payloads into Hashes before exceptions are raised.
• Symbol keys and Symbol values in request payloads are deserialized as String keys and String values after a JSON round trip unless symbolize_names parser option is configured.
• Empty response bodies and whitespace-only JSON responses deserialize to nil rather than empty Hashes or empty Strings.
• Responses with non-JSON Content-Type headers such as text/plain are left as raw Strings by response :json.
• Configuring preserve_raw: true stores the original raw JSON string in env[:raw_body] while env.body holds the parsed Hash.
