Request subclass which handles in-memory Data download using URLSessionDataTask.

public class DataRequest:​ Request

Request

A closure used to validate a request that takes a URL request, a URL response and data, and returns whether the request was valid.

public typealias Validation = (URLRequest?, HTTPURLResponse, Data?) -> ValidationResult

URLRequestConvertible value used to create URLRequests for this instance.

let convertible:​ URLRequestConvertible

Data read from the server so far.

var data:​ Data?

Validates the request, using the specified closure.

@discardableResult public func validate(_ validation:​ @escaping Validation) -> Self

• validation:​ Validation closure used to validate the response.

The instance.

Adds a handler to be called once the request has finished.

@discardableResult public func response(queue:​ DispatchQueue = .main, completionHandler:​ @escaping (AFDataResponse<Data?>) -> Void) -> Self

• queue:​ The queue on which the completion handler is dispatched. .main by default.
• completionHandler:​ The code to be executed once the request has finished.

The request.

Adds a handler to be called once the request has finished.

@discardableResult public func response<Serializer:​ DataResponseSerializerProtocol>(queue:​ DispatchQueue = .main, responseSerializer:​ Serializer, completionHandler:​ @escaping (AFDataResponse<Serializer.SerializedObject>) -> Void) -> Self

• queue:​ The queue on which the completion handler is dispatched. .main by default
• responseSerializer:​ The response serializer responsible for serializing the request, response, and data.
• completionHandler:​ The code to be executed once the request has finished.

The request.

Adds a handler to be called once the request has finished.

@discardableResult public func responseData(queue:​ DispatchQueue = .main, completionHandler:​ @escaping (AFDataResponse<Data>) -> Void) -> Self

• queue:​ The queue on which the completion handler is dispatched. .main by default.
• completionHandler:​ The code to be executed once the request has finished.

The request.

Adds a handler to be called once the request has finished.

@discardableResult public func responseString(queue:​ DispatchQueue = .main, encoding:​ String.Encoding? = nil, completionHandler:​ @escaping (AFDataResponse<String>) -> Void) -> Self

• queue:​ The queue on which the completion handler is dispatched. .main by default.
• encoding:​ The 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.
• completionHandler:​ A closure to be executed once the request has finished.

The request.

Adds a handler to be called once the request has finished.

@discardableResult public func responseJSON(queue:​ DispatchQueue = .main, options:​ JSONSerialization.ReadingOptions = .allowFragments, completionHandler:​ @escaping (AFDataResponse<Any>) -> Void) -> Self

• queue:​ The queue on which the completion handler is dispatched. .main by default.
• options:​ The JSON serialization reading options. .allowFragments by default.
• completionHandler:​ A closure to be executed once the request has finished.

The request.

Adds a handler to be called once the request has finished.

@discardableResult public func responseDecodable<T:​ Decodable>(of type:​ T.Type = T.self, queue:​ DispatchQueue = .main, decoder:​ DataDecoder = JSONDecoder(), completionHandler:​ @escaping (AFDataResponse<T>) -> Void) -> Self

• type:​ Decodable type to decode from response data.
• queue:​ The queue on which the completion handler is dispatched. .main by default.
• decoder:​ DataDecoder to use to decode the response. JSONDecoder() by default.
• completionHandler:​ A closure to be executed once the request has finished.

The request.

Validates that the response has a status code in the specified sequence.

@discardableResult public func validate<S:​ Sequence>(statusCode acceptableStatusCodes:​ S) -> Self where S.Iterator.Element == Int

If validation fails, subsequent calls to response handlers will have an associated error.

• range:​ The range of acceptable status codes.

The request.

Validates that the response has a content type in the specified sequence.

@discardableResult public func validate<S:​ Sequence>(contentType acceptableContentTypes:​ @escaping @autoclosure () -> S) -> Self where S.Iterator.Element == String

If validation fails, subsequent calls to response handlers will have an associated error.

• contentType:​ The acceptable content types, which may specify wildcard types and/or subtypes.

The request.

Validates that the response has a status code in the default acceptable range of 200...299, and that the content type matches any specified in the Accept HTTP header field.

@discardableResult public func validate() -> Self

If validation fails, subsequent calls to response handlers will have an associated error.
