如何在Blazor客户端正确获取facebook登录令牌？

<script>
  window.fbAsyncInit = function() {
    FB.init({
      appId      : 'YOUR_APP_ID',
      cookie     : true,
      xfbml      : true,
      version    : 'v13.0'
    });
  };

  (function(d, s, id){
     var js, fjs = d.getElementsByTagName(s)[0];
     if (d.getElementById(id)) {return;}
     js = d.createElement(s); js.id = id;
     js.src = "https://connect.facebook.net/en_US/sdk.js";
     fjs.parentNode.insertBefore(js, fjs);
   }(document, 'script', 'facebook-jssdk'));
</script>

@using Microsoft.JSInterop

@page "/facebook-login"

@inject IJSRuntime JSRuntime

<button @onclick="LoginWithFacebook">Login with Facebook</button>

@code {
    private async Task LoginWithFacebook()
    {
        try
        {
            var result = await JSRuntime.InvokeAsync<string>("getFacebookAccessToken");
            // 在这里处理获取到的令牌
            Console.WriteLine(result);
        }
        catch (Exception ex)
        {
            // 处理异常
            Console.WriteLine(ex.Message);
        }
    }
}

window.getFacebookAccessToken = function() {
  return new Promise(function(resolve, reject) {
    FB.login(function(response) {
      if (response.authResponse) {
        resolve(response.authResponse.accessToken);
      } else {
        reject(new Error('Facebook login failed'));
      }
    }, { scope: 'email' });
  });
};
