500在本地开发Heroku PHP Facebook应用程序时出错 - 500 error developing Heroku PHP Facebook app locally

500 error developing Heroku PHP Facebook app locally

我正在尝试用PHP在Heroku上开发一个Facebook应用程序。我设置了默认的Heroku Facebook应用程序，它在生产服务器上运行良好。我在Facebook上设置了另一个应用程序作为本地测试应用程序，并将URL设置为http://profanitytracker.localhost.我将这个URL设置为Apache VirtualHost，并放入开发应用程序的应用程序ID和Secret中。当我尝试在本地运行我的应用程序时，我会收到一个HTTP500错误。

以下是我在浏览器中看到的内容。。。

The website encountered an error while retrieving http://profanitytracker.localhost/?state=4109e82dd75dc7a224c2b01bbb3d2c7b&code=AQC26Ff9DZBhbT2cd4Zc-0KTNDsIooYzmEKVM_YTWxKYX3RF4V389qHBGUuH4_3PnUIOyXBYFmq7GKPK_b2bskYNLkj7aWHnOQHQI1NxmklZRCIuaUZA0nYfsEhJDDhxUmaYG0DICIRgrM_S3bWuN69VGOZSWqWlsA0ioyGh1ufa5-8Nd9LhSm6iREV54miQmgU#_=_. It may be down for maintenance or configured incorrectly.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

以下是Apache服务器日志中出现的错误。。。

看起来您没有安装cURL函数。

运行php_info（）文件，检查是否有任何提及cURL函数的内容。
