MVC5 Facebook身份验证-帐户/ExternalLoginCallback？错误=访问被拒绝#_=_

为什么在调试并以本地主机的身份运行应用程序时，但在发布到1和1.com后，我无法通过Facebook成功登录

我做这件事已经快一个星期了。我在我读过的每一个论坛上都尝试了一切，但收效甚微。问题是，它在作为本地主机运行时工作，但在发布到我的生产站点时失败。制作网站由1和1.com托管。令人困惑的是，我曾经能够在生产环境中进行身份验证；但从那以后就没有了。在visual Studio 2017中创建新的MVC Web应用程序时，整个项目几乎都是默认设置。以下是整个设置：

Facebook应用程序设置：

• 应用程序域：

  smarthomeprodealer.com

• 网站URL:

  https://smarthomeprodealer.com

• 客户端OAuth登录：

  Yes

• Web OAuth登录：

  Yes

• 强制Web OAuth重新验证：

  Yes

• 对重定向URI使用严格模式：

  Yes

• 强制HTTPS:

  Yes

• 嵌入式浏览器OAuth登录：

  No

• 有效的OAuth Redirct URI:

  https://smarthomeprodealer.com/

  https://localhost:44300/

为什么在调试和运行应用程序时，我能够通过Facebook成功登录到localhost，但在发布到1和1.com后却无法成功登录？

我知道已经有一段时间了，但在与托管团队进行故障排除后，他们建议我将其放到web.cofig中，结果成功了

这里也有同样的问题，在登台时运行正常，在生产时返回error=access\u denied\u=\u。嗨，您解决了这个问题吗？我注意到，我们都有同一家主机公司“ionos”，这可能是原因吗？@HamdanDabbas我从来没有这样做过。我最终搁置了这个项目。我仍然想继续这个项目，这就是我被卡住的地方。现在我确定这是一个托管问题，“ionos”团队说他们没有从他们这边阻止任何东西，但我确定这是他们的错，无论如何，我在GoDaddy托管上使用相同的方法和DLL，它工作得很好，没有任何问题。@HamdanDabbas很高兴知道。谢谢你提供的信息。
