如何在iOS上的Parse Server上實施Google登錄？

Question

我正在使用Parse Server來託管我的應用程序，並且目前使用用戶名和密碼以及Facebook進行身份驗證。我也想使用Google。似乎沒有指導如何做到這一點，所以任何幫助將不勝感激。

我熟悉使用適用於iOS的Google SignIn SDK，但不會將其與Parse集成。

謝謝。

在服務器上啓用OAuth的（將在futher更新被棄用，改爲權威性）

oauth: { 
    google: true 
}, 

在客戶端創建一個AuthDelegate

class AuthDelegate : NSObject, PFUserAuthenticationDelegate { 
    func restoreAuthentication(withAuthData authData: [String : String]?) -> Bool { 
     return true 
    } 
} 

使用谷歌SDK來簽到，並得到UserID和AccessToken

func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) { 
    print(user.userID) 
    print(user.authentication.accessToken) 
    print(user.authentication.accessTokenExpirationDate) 
} 

設置驗證數據通過驗證

PFUser.logInWithAuthType(inBackground: "google", authData: authd) 

let authd : [String: String] = ["id":"\(user.userID!)","expiration_date":"\(user.authentication.accessTokenExpirationDate!)","access_token":"\(gToken!)"] 

登錄在解析請注意，您必須考慮續約的accessToken自己（客戶端或服務器端）

這裏是我的版本實現谷歌拍在與中分析服務器。

import UIKit 
import Parse 
import KVNProgress 
import GoogleSignIn 

class GoogleAuthWorker: NSObject { 
    /// http://nsdateformatter.com 
    lazy var dateFormatter: DateFormatter = { 
     let formatter = DateFormatter() 
     formatter.dateFormat = "yyyy-MM-dd HH:mm:ss Z" 
     return formatter 
    }() 

    var googleSignIn = GIDSignIn.sharedInstance() 
    var completion: (Error?) -> Void = { } 
    weak var host: UIViewController? 

    /// Logs in with Google. Presents Safari view controller from the host view controller. 
    func logInWithGoogle(host: UIViewController?, completion: @escaping (Error?) -> Void) { 
     self.completion = completion 
     self.host = host 
     PFUser.register(self, forAuthType: "google") 
     googleSignIn?.delegate = self 
     googleSignIn?.uiDelegate = self 
     googleSignIn?.signIn() 
    } 
} 

// MARK: - PFUserAuthenticationDelegate 
extension GoogleAuthWorker: PFUserAuthenticationDelegate { 
    func restoreAuthentication(withAuthData authData: [String : String]?) -> Bool { 
     // Check whether expiration date is in future or not. 
     guard let expirationDateString = authData?["expiration_date"], 
      let expirationDate = dateFormatter.date(from: expirationDateString) else { return false } 
     return expirationDate > Date() 
    } 
} 

// MARK: - GIDSignInDelegate 
extension GoogleAuthWorker: GIDSignInDelegate { 
    func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) { 
     guard let user = user else { 
      let appError = AppError.googleError(underlyingError: error) 
      self.completion(.failure(error: appError)) 
      return 
     } 
     let authData: [String: String] = ["id": user.userID, 
              "id_token": user.authentication.idToken, 
              "expiration_date": "\(user.authentication.accessTokenExpirationDate!)", 
              "access_token": user.authentication.accessToken] 
     // Ask PFUser to log in with given auth data. 
     PFUser.logInWithAuthType(inBackground: "google", authData: authData).continue({ (task) -> Any? in 
      if let userObject = task.result { 
       // Fill userObject (which is PFUser) by profile data, like: 
       //userObject.email = user.profile.email 
       //userObject.password = UUID().uuidString 
       //userObject["firstName"] = user.profile.givenName 
       //userObject["lastName"] = user.profile.familyName 
       self.completion(nil) 
      } else { 
       // Failed to log in. 
       self.completion(task.error) 
      } 
      return nil 
     }) 
    } 
} 

// MARK: - GIDSignInUIDelegate 
extension GoogleAuthWorker: GIDSignInUIDelegate { 
    func sign(inWillDispatch signIn: GIDSignIn!, error: Error!) { 
    } 

    func sign(_ signIn: GIDSignIn!, present viewController: UIViewController!) { 
     host?.present(viewController, animated: true, completion: nil) 
    } 

    func sign(_ signIn: GIDSignIn!, dismiss viewController: UIViewController!) { 
     host?.dismiss(animated: true, completion: nil) 
    } 
}
