facebook集成错误2500 oautheexception xcode 8 Swift

Question

我正在xcode 8 Swift 3中整合facebook。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
        }

但我得到低于错误。

可选(误差域= com.facebook.sdk。core Code=8 "(null)"用户信息= {com.facebook。sdk: FBSDKGraphRequestErrorCategoryKey = 0, com.facebook。sdk: com.facebook FBSDKGraphRequestErrorHTTPStatusCodeKey = 400。sdk:FBSDKErrorDeveloperMessageKey=必须使用活动访问令牌来查询当前用户的信息。, com.facebook。sdk: FBSDKGraphRequestErrorGraphErrorCode = 2500, com.facebook.sdk: FBSDKGraphRequestErrorParsedJSONResponseKey = {Body = {错误= {代码= 2500;"fbtrace_id" = "FmK/8qacfthe ";message = "必须使用活动访问令牌来查询当前用户的信息";type = oautheexception;}；}；代码= 400;}})有人能帮我一下吗?

Answer 1

函数loginButton(_ loginButton: FBSDKLoginButton!)， didCompleteWith result: FBSDKLoginManagerLoginResult!) {print("Login button click ")

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"]!)
        }
})

}
