A ResponseSerializer that decodes the response data as a String. By default, a request returning nil or no data is considered an error. However, if the response is has a status code valid for empty responses (204, 205), then an empty String is returned.

public final class StringResponseSerializer:​ ResponseSerializer

ResponseSerializer

Creates an instance with the provided values.

public init(dataPreprocessor:​ DataPreprocessor = StringResponseSerializer.defaultDataPreprocessor, encoding:​ String.Encoding? = nil, emptyResponseCodes:​ Set<Int> = StringResponseSerializer.defaultEmptyResponseCodes, emptyRequestMethods:​ Set<HTTPMethod> = StringResponseSerializer.defaultEmptyRequestMethods)

• dataPreprocessor:​ DataPreprocessor used to prepare the received Data for serialization.
• encoding:​ A string encoding. Defaults to nil, in which case the encoding will be determined from the server response, falling back to the default HTTP character set, ISO-8859-1.
• 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.
