我点击了链接https://learn.microsoft.com/en-us/azure/app-service-mobile/app-service-mobile-how-to-configure-facebook-authentication设置 Facebook 登录。
在 https://developers.facebook.com/apps ，“有效的 OAuth 重定向 URI”具有以下 URI
https://myapp.azurewebsites.net/signin-facebook
https://myapp.azurewebsites.net/.auth/login/facebook/callback
但是，该网站无法登录 - 登录页面仍然存在。输入网址 https://myapp.azurewebsites.net/event将始终重定向到 https://myapp.azurewebsites.net/Account/Login?ReturnUrl=%2Fevent .

最佳答案
我可能会遇到同样的问题，经过一番搜索后我发现 facebook graph api 做了一些更改。以下是详细信息，您可以引用:
Facebook Graph API 强制升级:Changes from v2.2 to v2.3
[Oauth Access Token] Format - The response format of https://www.facebook.com/v2.3/oauth/access_token returned when you exchange a code for an access_token now return valid JSON instead of being URL encoded. The new format of this response is {"access_token": {TOKEN}, "token_type":{TYPE}, "expires_in":{TIME}}. We made this update to be compliant with section 5.1 of RFC 6749.
自 access_token返回 JSON，而不是编码的 URL，Microsoft.Owin.Security.Facebook 3.1.0 之前的版本无法处理此更改。您需要将 Microsoft.Owin.Security.Facebook 升级到 3.1.0 版本，或者需要实现 FacebookAuthenticationOptions.BackchannelHttpHandler有关处理此更改的解决方法，有关更多详细信息，您可以引用类似的 answer .
更新
据我所知，X-Frame-Options指示是否允许浏览器呈现 <frame> 中的页面, <iframe>或<object> ，我认为这个标题与您的问题无关。由于您的网络包来自您的客户端，因此当您使用authorization_code时您看不到处理过程。交换access_token来自 Facebook 。我建议您可以在本地运行 Web 应用程序并捕获包，如下所示:
我已检查将 Microsoft.Owin.Security.Facebook 更新至 3.1.0 并实现 FacebookAuthenticationOptions.BackchannelHttpHandler按照此issue ，两者都可以在我这边和 azure 上工作。总之，您可以获得 authorization_code但未能提取access_token ，我假设您需要清除/重建您的项目并确保您的项目可以在本地运行，然后将您的项目重新部署到Web应用程序(如果您通过VS发布向导部署网站，您可以选择“删除附加文件”在设置 > 文件发布选项下的目的地”，或者您可以使用 KUDU 清空您的网络内容)。
更新2
我创建了一个代码示例 AspDotNet-WebApplication-FacebookAuth使用我的 Facebook 应用程序，您可以尝试在本地运行并确保可以检索 access_token并获取登录的用户信息如下:
