Yahoo Weather API в быстром Дополнительный аргумент в запросе oauth

Question

Я пытаюсь интегрировать службу Yahoo API в мое приложение IOS (https://developer.yahoo.com/weather/documentation.html#oauth -swift ). У меня не было проблем с android, но теперь я испытываю проблему с компилятором swift и Xcode11. Я добавил модуль Oauth: https://cocoapods.org/pods/OAuthSwift и код в документации:

import Foundation
/*
See https://github.com/OAuthSwift/OAuthSwift for information on
including this OAuth library in your project.
*/
import OAuthSwift

enum YahooWeatherAPIResponseType:String {
    case json = "json"
    case xml = "xml"
}

enum YahooWeatherAPIUnitType:String {
    case imperial = "f"
    case metric = "c"
}

fileprivate struct YahooWeatherAPIClientCredentials {
    var appId = ""
    var clientId = ""
    var clientSecret = ""
}

class YahooWeatherAPI {
    // Configure the following with your values.
    private let credentials = YahooWeatherAPIClientCredentials(appId: "-your-app-id-", clientId: "-your-client-id-", clientSecret: "-your-client-secret-")

    private let url:String = "https://weather-ydn-yql.media.yahoo.com/forecastrss"
    private let oauth:OAuth1Swift?

    public static let shared = YahooWeatherAPI()

    private init() {
        self.oauth = OAuth1Swift(consumerKey: self.credentials.clientId, consumerSecret: self.credentials.clientSecret)
    }

    private var headers:[String:String] {
        return [
            "X-Yahoo-App-Id": self.credentials.appId
        ]
    }

    /// Requests weather data by location name.
    ///
    /// - Parameters:
    ///   - location: the name of the location, i.e. sunnyvale,ca
    ///   - failure: failure callback
    ///   - success: success callback
    ///   - responseFormat: .xml or .json. default is .json.
    ///   - unit: metric or imperial units. default = .imperial

    public func weather(location:String, failure: @escaping (_ error: OAuthSwiftError) -> Void, success: @escaping (_ response: OAuthSwiftResponse) -> Void, responseFormat:YahooWeatherAPIResponseType = .json, unit:YahooWeatherAPIUnitType = .imperial) {
        self.makeRequest(parameters: ["location":location, "format":responseFormat.rawValue, "u":unit.rawValue], failure: failure, success: success)
    }


    /// Requests weather data by woeid (Where on Earth ID)
    ///
    /// - Parameters:
    ///   - woeid: The location's woeid
    ///   - failure: failure callback
    ///   - success: success callback
    ///   - responseFormat: .xml or .json. default is .json.
    ///   - unit: metric or imperial units. default = .imperial

    public func weather(woeid:String, failure: @escaping (_ error: OAuthSwiftError) -> Void, success: @escaping (_ response: OAuthSwiftResponse) -> Void, responseFormat:YahooWeatherAPIResponseType = .json, unit:YahooWeatherAPIUnitType = .imperial) {
        self.makeRequest(parameters: ["woeid":woeid, "format":responseFormat.rawValue, "u":unit.rawValue], failure: failure, success: success)
    }


    /// Requests weather data by latitude and longitude
    ///
    /// - Parameters:
    ///   - lat: latitude
    ///   - lon: longiture
    ///   - failure: failure callback
    ///   - success: success callback
    ///   - responseFormat: .xml or .json. default is .json.
    ///   - unit: metric or imperial units. default = .imperial
    public func weather(lat:String, lon:String, failure: @escaping (_ error: OAuthSwiftError) -> Void, success: @escaping (_ response: OAuthSwiftResponse) -> Void, responseFormat:YahooWeatherAPIResponseType = .json, unit:YahooWeatherAPIUnitType = .imperial) {
        self.makeRequest(parameters: ["lat":lat, "lon":lon, "format":responseFormat.rawValue, "u":unit.rawValue], failure: failure, success: success)
    }


    /// Performs the API request with the OAuthSwift client
    ///
    /// - Parameters:
    ///   - parameters: Any URL parameters to pass to the endpoint.
    ///   - failure: failure callback
    ///   - success: success callback
    private func makeRequest(parameters:[String:String], failure: @escaping (_ error: OAuthSwiftError) -> Void, success: @escaping (_ response: OAuthSwiftResponse) -> Void) {
        self.oauth?.client.request(self.url, method: .GET, parameters: parameters, headers: self.headers, body: nil, checkTokenExpiration: true, success: success, failure: failure)
    }

}

НО я получаю ошибку компилятора "Ошибка дополнительного аргумента" в последнем makerequest функция (см. приложение).

  private func makeRequest(parameters:[String:String], failure: @escaping (_ error: OAuthSwiftError) -> Void, success: @escaping (_ response: OAuthSwiftResponse) -> Void) {
        self.oauth?.client.request(self.url, method: .GET, parameters: parameters, headers: self.headers, body: nil, checkTokenExpiration: true, success: success, failure: **failure**)
    }

[Ошибка компилятора] [1]

Кто-нибудь имеет опыт работы с Oauth и такого рода проблемами? Кто-нибудь может мне помочь?

Большое спасибо заранее

Вот как должен вызываться запрос Yahooweather Oauth (благодаря jawadAli):

  public func weather(lat:String, lon:String, responseFormat:YahooWeatherAPIResponseType = .json, unit:YahooWeatherAPIUnitType = .imperial,completion: OAuthSwiftHTTPRequest.CompletionHandler?) {

         self.makeRequest(parameters: ["lat":lat, "lon":lon, "format":responseFormat.rawValue, "u":unit.rawValue], completion: completion)
    }

    private func makeRequest(parameters:[String:String], completion: OAuthSwiftHTTPRequest.CompletionHandler?) {

        self.oauth?.client.request(self.url, method: .GET, parameters: parameters, headers: self.headers, body: nil, checkTokenExpiration: true, completionHandler: completion)}

Answer 1

Использовать функцию OAuth2Swift

self.client.request(accessTokenUrl, method: .POST, parameters: parameters, headers: finalHeaders, checkTokenExpiration: false, completionHandler: completionHandler)

Фактические параметры запроса клиента:

func request(_ url: URLConvertible, method: OAuthSwiftHTTPRequest.Method, parameters: OAuthSwift.Parameters = [:], headers: OAuthSwift.Headers? = nil, body: Data? = nil, checkTokenExpiration: Bool = true, completionHandler completion: OAuthSwiftHTTPRequest.CompletionHandler?) -> OAuthSwiftRequestHandle?

Он принимает обработчик завершения вместо успеха Failure

надеюсь, что это решит вашу проблему

проверьте этот код ... Вам нужно отдельно отправить обработчик завершения вместо успешного или неудачного

fileprivate func requestOAuthAccessToken(withParameters parameters: OAuthSwift.Parameters, headers: OAuthSwift.Headers? = nil, completionHandler completion: @escaping TokenCompletionHandler) -> OAuthSwiftRequestHandle? {

        let completionHandler: OAuthSwiftHTTPRequest.CompletionHandler = { [weak self] result in
            guard let this = self else {
                OAuthSwift.retainError(completion)
                return
            }
            switch result {
            case .success(let response):
                let responseJSON: Any? = try? response.jsonObject(options: .mutableContainers)

                let responseParameters: OAuthSwift.Parameters

                if let jsonDico = responseJSON as? [String: Any] {
                    responseParameters = jsonDico
                } else {
                    responseParameters = response.string?.parametersFromQueryString ?? [:]
                }

                guard let accessToken = responseParameters["access_token"] as? String else {
                    let message = NSLocalizedString("Could not get Access Token", comment: "Due to an error in the OAuth2 process, we couldn't get a valid token.")
                    completion(.failure(.serverError(message: message)))
                    return
                }

                if let refreshToken = responseParameters["refresh_token"] as? String {
                    this.client.credential.oauthRefreshToken = refreshToken.safeStringByRemovingPercentEncoding
                }

                if let expiresIn = responseParameters["expires_in"] as? String, let offset = Double(expiresIn) {
                    this.client.credential.oauthTokenExpiresAt = Date(timeInterval: offset, since: Date())
                } else if let expiresIn = responseParameters["expires_in"] as? Double {
                    this.client.credential.oauthTokenExpiresAt = Date(timeInterval: expiresIn, since: Date())
                }

                this.client.credential.oauthToken = accessToken.safeStringByRemovingPercentEncoding
                completion(.success((this.client.credential, response, responseParameters)))
            case .failure(let error):
                completion(.failure(error))
            }
        }

изменить определение метода на

private func makeRequest(parameters:[String:String], completion: @escaping TokenCompletionHandler) -> OAuthSwiftRequestHandle?)

этот TokenCompletionHandler является ResultType .... вы можете добавить переключатель случаев сбоя или успеха ... дайте мне знать, если вам нужна дополнительная помощь
