问题描述

我点击了链接

我已检查将 Microsoft.Owin.Security.Facebook 更新到 3.1.0 并实施

I followed the link https://docs.microsoft.com/en-us/azure/app-service-mobile/app-service-mobile-how-to-configure-facebook-authentication to set up Facebook login.

In the https://developers.facebook.com/apps, the "Valid OAuth redirect URIs" has the following URIs

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

However, the site cannot login - the login page just stays. Type an Url https://myapp.azurewebsites.net/event will always redirect to https://myapp.azurewebsites.net/Account/Login?ReturnUrl=%2Fevent.

The following is the Net traffic captured by fiddler. It seems the request is denied when GET https://myapp.azurewebsites.net/signin-facebook?code=.... (Response: Location: /Account/ExternalLoginCallback?error=access_denied)

Update: After updated Microsoft.Owin.Security.Facebook, facebook login prompted me to register a new user. However, it still redirect to login page? The following is the http traffic.

There is a X-Frame-Options: DENY for the request of GET https://www.facebook.com/v2.8/dialog/oauth?response_type=code&client_id=....

解决方案

I could encounter the same issue, after some searches I found that the facebook graph api did some changes. Here is the detailed info, you could refer to it:

Facebook Graph API has a force upgrade: 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.

Since the access_token returned with the JSON instead of the URL encoded, Microsoft.Owin.Security.Facebook prior to 3.1.0 could not handle this change. You need to upgrade Microsoft.Owin.Security.Facebook to 3.1.0 version, or you need to implement the FacebookAuthenticationOptions.BackchannelHttpHandler for a workaround to handle this change, for more details, you could refer to this similar answer.

UPDATE

As I known, X-Frame-Options indicates whether or not a browser should be allowed to render a page in a <frame>, <iframe> or <object>, I assumed that this header has no relation with your issue. Since your network packages are from your client, you could not see the processing when you use authorization_code to exchange the access_token from facebook. I recommended that you could run your web app on your local side and capture the packages as follows:

I have checked both update Microsoft.Owin.Security.Facebook to 3.1.0 and implement FacebookAuthenticationOptions.BackchannelHttpHandler by following this issue, both could work on my side and azure. In summary, you could get the authorization_code but failed to extract the access_token, I assumed that you need to clear/rebuild your project and make sure your project could work on your local side, then redeploy your project to web app (if you deploy the website via VS publish wizard, you could choose the "Remove additional files at destination" under Settings > File Publish Options or you could use KUDU to empty your web content).

UPDATE2

I have created a code sample AspDotNet-WebApplication-FacebookAuth with my facekbook app, you could try to run on your local side and make sure you could retrieve the access_token and get the logged user info as follows:
