facebook集成错误2500 OAuthException xcode 8 Swift 3

Question

我正在开发xcode 8 Swift 3中的facebook集成。我使用了以下代码

let parameters = ["fields": "email, first_name, last_name, picture.type(large)"]

    FBSDKGraphRequest.init(graphPath: "me", parameters: parameters).start { (connection, result, error) in
        if error != nil{
            print(error)
            return
        }

但我的错误越来越少了。

可选( error Domain=com.facebook.sdk.core Code=8 "(null)“)”必须使用com.facebook.sdk:FBSDKGraphRequestErrorGraphErrorCode=2500，com.facebook.sdk:FBSDKGraphRequestErrorParsedJSONResponseKey={活动访问令牌查询有关当前用户的信息。，com.facebook.sdk:FBSDKGraphRequestErrorGraphErrorCode=2500，com.facebook.sdk:FBSDKGraphRequestErrorParsedJSONResponseKey={ body ={Domain=com.facebook.sdk.core={Domain=com.facebook.sdk.core= 2500；"fbtrace_id“=”FmK/8 8QACfhe“；message =“必须使用活动访问令牌来查询有关当前用户的信息。”；type = OAuthException；}；}；code = 400；})有人能帮助我吗？

func loginButton(_ loginButton: FBSDKLoginButton!，didCompleteWith结果: FBSDKLoginManagerLoginResult!，error: Error!) {print(“loginButton单击”)

let graphRequest:FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"first_name, gender, last_name, email, picture.type(large)"])

graphRequest.start(completionHandler: { (connection, result, error) -> Void in

    if ((error) != nil)
    {
        print("Error: \(error)")
    }
    else
    {
            let data:[String:AnyObject] = result as! [String : AnyObject]
            print(data["first_name"]!)
            print(data["last_name"]!)
            print(data["email"]!)
            print(data["id"]!)
            print(data["gender"]!)
        }
})

}
