public final class ModifyRequestNetworkService : NetworkService

ModifyRequestNetworkService can be composed with a network service to modify all outgoing requests. One could add auth tokens or API keys for specifics URLs.

Example:

let networkService: NetworkService = //
let modifyRequestNetworkService = ModifyRequestNetworkService(networkService: networkService, requestModifications: [ { request in
   return request.added(HTTPHeaderFields: ["API-Key": "SecretKey"])
}])

  • Fetches a resource asynchronously from remote location. Execution of the requests starts immediately. Execution happens on no specific queue. It dependes on the network access which queue is used. Once execution is finished either the completion block or the error block gets called. You decide on which queue these blocks get executed.

    Example:

    let networkService: NetworkService = //
let resource: Resource<String> = //

networkService.request(queue: .main, resource: resource, onCompletionWithResponse: { htmlText, response in
   print(htmlText, response)
}, onError: { error in
   // Handle errors
})

public func request<Result>(queue: DispatchQueue, resource: Resource<Result>, onCompletionWithResponse: @escaping (Result, HTTPURLResponse) -> Void,
                    onError: @escaping (NetworkError) -> Void) -> NetworkTask
