facebook 集成错误 2500 OAuthException xcode 8 Swift 3

Question

我正在 xcode 8 Swift 3 中进行 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
        }

但是我遇到了以下错误。

Optional(Error Domain=com.facebook.sdk.core Code=8 "(null)" UserInfo={com.facebook.sdk:FBSDKGraphRequestErrorCategoryKey=0, com.facebook.sdk:FBSDKGraphRequestErrorHTTPStatusCodeKey=400, com.facebook.sdk:FBSDKErrorDeveloperMessageKey=An active access token must be used to query information about the current user., com.facebook.sdk:FBSDKGraphRequestErrorGraphErrorCode=2500, com.facebook.sdk:FBSDKGraphRequestErrorParsedJSONResponseKey={ body = { error = { code = 2500; "fbtrace_id" = "FmK/8QACfhe"; message = "An active access token must be used to query information about the current user."; type = OAuthException; }; }; code = 400; }}) can anyone help me out this ??

func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: 错误!) { 打印（"Login buttoon clicked"）

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"]!)
        }
})
