解决方案

阅读错误消息，它与您的代码无关，您需要配置您的Facebook应用程序以允许从该域访问

{ "error": {
"message": "Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings.",
"type": "OAuthException",
"code": 191,
"fbtrace_id": "Gn/EdIdQhGh"
}
}

解决方案

Read the error message, it's nothing to do with your code, you need to configure your facebook app to allow access from that domain.
