Unity fires"；用户取消登录“；每次

我计划在WEBGL版本的游戏中使用Facebook登录。

每次我尝试登录时，我都会收到"用户取消登录"，

我的应用程序是公共的，设置->高级->客户端OAuth设置-所有这些都已启用

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using Facebook.Unity;
public class FaceLogin : MonoBehaviour
{
    void Awake()
    {
        if (!FB.IsInitialized)
        {
            // Initialize the Facebook SDK
            FB.Init(InitCallback, OnHideUnity);
        }
        else
        {
            // Already initialized, signal an app activation App Event
            FB.ActivateApp();
        }
    }
    private void InitCallback()
    {
        if (FB.IsInitialized)
        {
            // Signal an app activation App Event
            FB.ActivateApp();
            // Continue with Facebook SDK
            // ...
            if (!FB.IsLoggedIn)
            {
                var perms = new List<string> {"public_profile", "email", "user_friends"};
                FB.LogInWithReadPermissions(perms, AuthCallback);
            }
        }
        else
        {
            Debug.Log("Failed to Initialize the Facebook SDK");
        }
    }
    private void OnHideUnity(bool isGameShown)
    {
        Time.timeScale = !isGameShown ? 0 : 1;
    }
    private void AuthCallback(ILoginResult result)
    {
        if (FB.IsLoggedIn)
        {
            // AccessToken class will have session details
            var aToken = AccessToken.CurrentAccessToken;
            // Print current access token's User ID
            Debug.Log(aToken.UserId);
            // Print current access token's granted permissions
            foreach (string perm in aToken.Permissions)
            {
                Debug.Log(perm);
            }
        }
        else
        {
            Debug.Log("User cancelled login");
        }
    }
}
