DecodableResponseSerializer

public final class DecodableResponseSerializer<T> : ResponseSerializer where T : Decodable

A ResponseSerializer that decodes the response data as a generic value using any type that conforms to DataDecoder. By default, this is an instance of JSONDecoder. Additionally, a request returning nil or no data is considered an error. However, if the request has an HTTPMethod or the response has an HTTP status code valid for empty responses then an empty value will be returned. If the decoded type conforms to EmptyResponse, the type’s emptyValue() will be returned. If the decoded type is Empty, the .value instance is returned. If the decoded type does not conform to EmptyResponse and isn’t Empty, an error will be produced.

Declaration

Swift

public init(dataPreprocessor: DataPreprocessor = DecodableResponseSerializer.defaultDataPreprocessor,

Parameters

`dataPreprocessor`	`DataPreprocessor` used to prepare the received `Data` for serialization.

`emptyResponseCodes`	The HTTP response codes for which empty responses are allowed. `[204, 205]` by default.
`emptyRequestMethods`	The HTTP request methods for which empty responses are allowed. `[.head]` by default.
