Question

我按照https://docs.microsoft.com/en-us/azure/app-service-mobile/app-service-mobile-how-to-configure-facebook-authentication链接设置了Facebook登录信息。

在https://developers.facebook.com/apps中，“有效OAuth重定向URI”具有以下URI

https://myapp.azurewebsites.net/signin-facebook 
https://myapp.azurewebsites.net/.auth/login/facebook/callback

然而，该网站无法登录 - 登录页面只是停留。输入网址https://myapp.azurewebsites.net/event将始终重定向到https://myapp.azurewebsites.net/Account/Login?ReturnUrl=%2Fevent。

以下是fiddler捕获的网络流量。 GET https://myapp.azurewebsites.net/signin-facebook?code=....（响应：Location: /Account/ExternalLoginCallback?error=access_denied）

时，请求似乎被拒绝

更新更新了Microsoft.Owin.Security.Facebook后，facebook登录提示我注册一个新用户。但是，它仍然重定向到登录页面？以下是http流量。

Answer 1

我可能遇到同样的问题，经过一些搜索我发现facebook图表api做了一些改动。以下是详细信息，您可以参考：

Facebook Graph API具有强制升级功能：Changes from v2.2 to v2.3

[Oauth访问令牌]格式 - 当您交换access_token的代码时返回的https://www.facebook.com/v2.3/oauth/ access_token的响应格式现在返回有效的JSON而不是URL编码。此回复的新格式为{“access_token”：{TOKEN}，“token_type”：{TYPE}，“expires_in”：{TIME}}。我们使此更新符合RFC 6749的第5.1节。

由于access_token返回的是JSON而不是编码的URL，因此3.1.0之前的Microsoft.Owin.Security.Facebook无法处理此更改。您需要将 Microsoft.Owin.Security.Facebook 升级到3.1.0版本，或者您需要实现FacebookAuthenticationOptions.BackchannelHttpHandler以获得解决方法来处理此更改，有关详细信息，请参阅这个类似的answer。

<强>更新

众所周知，X-Frame-Options表示是否应允许浏览器在<frame>，<iframe>或<object>中呈现网页，我认为此标题与您的问题无关。由于您的网络套餐来自您的客户，因此当您使用authorization_code从Facebook更换access_token时，您无法看到处理。我建议您可以在本地运行您的Web应用程序并按如下方式捕获程序包：

我已经检查了更新 Microsoft.Owin.Security.Facebook 到3.1.0并按照FacebookAuthenticationOptions.BackchannelHttpHandler实施issue，两者都可以在我身边和azure上工作。总之，您可以获得authorization_code但无法提取access_token，我认为您需要清除/重建项目并确保您的项目可以在本地工作，然后重新部署您的项目到网络应用程序（如果您通过VS发布向导部署网站，您可以选择设置＆gt;文件发布选项下的“删除目的地的其他文件”，或者您可以使用KUDU清空你的网站内容）。

<强> UPDATE2

我已经使用我的facekbook应用创建了代码示例AspDotNet-WebApplication-FacebookAuth，您可以尝试在本地运行，并确保您可以检索access_token并获取已记录的用户信息，如下所示：< / p>

Azure上的Asp.net无法登录facebook？位置：/ Account / ExternalLoginCallback？error = access_denied
