Yahoo Weather API在oauth请求中迅速添加了额外参数

Question

我正在尝试将Yahoo API服务集成到我的IOS应用（https://developer.yahoo.com/weather/documentation.html#oauth-swift）中。我对于android没有任何问题，但是现在我遇到了swift和Xcode11的编译器问题。我添加了Oauth pod：https://cocoapods.org/pods/OAuthSwift，以及文档中的代码：

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)
    }

}

但是我在最后一个makerequest函数中看到了编译器错误“ Extra parameter” failure“（请参阅附件）。

  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**)
    }

Compiler error

有人在Oauth和此类问题上有经验吗？有人可以帮我吗？

非常感谢

我现在要得到这个

我认为问题在于UIViewController中的初始请求和完成处理程序之间的连接：

 YahooWeatherAPI.shared.weather(location: "sunnyvale,ca", failure: { (error) in
            print(error.localizedDescription)
        }, success: { (response) in
                print(response.string as Any)
        }, responseFormat: .xml, unit: .metric)

self.makeRequest（参数：[“位置”：位置，“格式”：responseFormat.rawValue，“ u”：unit.rawValue]，完成：）]

}

/// Performs the API request with the OAuthSwift client
///
/// - Parameters:
///   - parameters: Any URL parameters to pass to the endpoint.
///   - failure: failure callback
///   - success: success callback

       let completionHandler: OAuthSwiftHTTPRequest.CompletionHandler = { [weak self] result in
           guard let this = self else {
               return
           }




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

    }

               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 {
                   }

                   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 {
                   }

                   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())
                   }

                   completion(.success((this.client!.credential, response, responseParameters)))
               case .failure(let error):
                   completion(.failure(error))
               }
     }
    }

如何在此处管理完成电话：???

 self.makeRequest(parameters: ["location":location, "format":responseFormat.rawValue, "u":unit.rawValue], **completion**: )

Answer 1

[使用OAuth2Swift函数

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

客户请求的实际参数为

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?

使用完成处理程序代替成功失败

希望它能解决您的问题

检查此代码...您需要发送转义的完成处理程序，而不是分别发送成功或失败

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))
            }
        }

将方法定义更改为

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

此TokenCompletionHandler是ResultType...。您可以添加失败或成功案例的开关...让我知道是否需要进一步的帮助
