如何写新的swift 3的Facebook Graph Request？

Question

我试图使用新的FacebookSdk为Swift3，但我无法弄清楚如何完成一个简单的Graph请求。我绝对有这一切错误。这是我在下面。有人想出来了吗？

import FacebookCore 
    import FacebookLogin 
    import FacebookShare 



    let parameters = ["fields": "id, name, gender, picture.width(300).height(300).type(large).redirect(false)"] 
       let nextrequest: GraphRequest = GraphRequest(graphPath: "me", parameters: parameters, accessToken: AccessToken.current, httpMethod: GraphRequestHTTPMethod(rawValue: "GET")!) 


       nextrequest.start({ (response: HTTPURLResponse?, result: GraphRequestResult<GraphRequest>) in 



        if error != nil { 
        } 

if let name = result["name"] as? String, let id = result["id"] as? String, let gender = result["gender"] as? String { 
        print(name) 
        print(id) 
        print(gender) 
} 
else {} 
       })

let parameters = ["fields":"name,gender,birthday,first_name,last_name,email"] 
       let graphRequest = FBSDKGraphRequest(graphPath:"me", parameters:parameters) 

       _ = graphRequest?.start { [weak self] connection, result, error in 
        // If something went wrong, we're logged out 
        if (error != nil) 
        { 
         print("graphrequest error :\(error?.localizedDescription)") 
         return 
        } 

        // Transform to dictionary first 
        if let result = result as? [String: Any] 
        { 
         guard let firstname = result["first_name"] as? String else { 

          return 
         } 

         guard let lastname = result["last_name"] as? String else { 

          return 
         } 

         guard let gender = result["gender"] as? String else { 

          return 
         } 

         guard let email = result["email"] as? String else { 

          return 
         } 

         guard let birthday = result["birthday"] as? String else { 

          return 
         } 

(...) 
        } 
       } // End of graph request

如果您仍然有问题，试试这个

let loginManager = LoginManager() 

    loginManager.logIn([ .publicProfile, .email, .userFriends ], viewController: self) { loginResult in 
     switch loginResult { 
     case .failed(let error): 
      print(error) 
     case .cancelled: 
      print("User cancelled login.") 

     case .success(let grantedPermissions, let declinedPermissions, let accessToken): 
      print("Logged in!") 

      let req = GraphRequest(graphPath: "me", parameters: ["fields":"email,first_name,last_name,gender,picture"], accessToken: accessToken, httpMethod: GraphRequestHTTPMethod(rawValue: "GET")!) 
     req.start({ (connection, result) in 
      switch result { 
      case .failed(let error): 
       print(error) 

      case .success(let graphResponse): 
       if let responseDictionary = graphResponse.dictionaryValue { 
        print(responseDictionary) 
        let firstNameFB = responseDictionary["first_name"] as! String 
        let lastNameFB = responseDictionary["last_name"] as! String 
        let socialIdFB = responseDictionary["id"] as! String 
        let genderFB = responseDictionary["gender"] as! String 
        let pictureUrlFB = responseDictionary["picture"] as! [String:Any] 
        let photoData = pictureUrlFB["data"] as! [String:Any] 
        let photoUrl = photoData["url"] as! String 
        print(firstNameFB, lastNameFB, socialIdFB, genderFB, photoUrl) 
       } 
      } 
     }) 

     } 

    }
