input'Any？' 没有下标成员

我试图检索电子邮件ID后fblogin在我的应用程序。 但是，当我尝试从结果中获取值时，出现错误。

错误是：inputType 'Any?' has no subscript members Type 'Any?' has no subscript members 。

 func fetchProfile() { print("Fetch Profile") let parameters = ["fields": "email, first_name, last_name, picture.type(large)"] FBSDKGraphRequest(graphPath: "me", parameters: parameters).start { (connection, result, error) in let email = result["email"] as? String //Type 'Any?' has no subscript members error occurs here. } } 

Answer 1

改变这一点

  let email = result["email"] as? String 

成

  guard let resultNew = result as? [String:Any] let email = resultNew["email"] as! String 

完整的答案

 let parameters = ["fields": "email, first_name, last_name, picture.type(large)"] FBSDKGraphRequest(graphPath: "me", parameters: parameters).start { (connection, result, error) in guard let resultNew = result as? [String:Any] let email = resultNew["email"] as! String }
