Facebook，谷歌的OAuth有时无法在Azure上 [英] Facebook, Google OAuth fails sometimes on Azure

问题描述

我使用Asp.Net MVC的OAuth登录与Facebook和谷歌和奇怪的事情，在某些时期，它亘古不变的工作

I am using Asp.Net MVC OAuth login with facebook and google and strange thing that at some period it doesnot work

var externalIdentity =
                HttpContext.GetOwinContext()
                    .Authentication.GetExternalIdentityAsync(DefaultAuthenticationTypes.ExternalCookie);

var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
if (loginInfo == null)
{
   return RedirectToAction("Login");
}

似乎在这里不能得到用户信息，并重定向到登录页面。我无法弄清楚，为什么还是什么可能会导致。
我也有两个插槽，测试和生产。

Seems here it cant get user info and redirect to login page. I cant figure out why or what can cause that. I also have two slots beta and production.

所以任何建议或也许有人已经拥有了，发现路该怎么解决呢？

So any suggestion or maybe somebody already have that and found way how to fix that?

推荐答案

几个星期后，我终于解决了我的问题。它真的有些奇怪，可能的问题是，因为天蓝色的，因为我的工作落实上VMvare之前6月份。

Finally after few weeks i solve my problem. Its really something strange and probably issue is because of azure because my implementation works on VMvare before for 6 month.

在的AccountController有法

in AccountController there is method

public ActionResult ExternalLogin(string provider, string returnUrl)

添加有

Session.RemoveAll();

PS /时的OAuth失败我只是简单地重新启动Web应用程序，它开始工作时，首先我看到了这个建议，我不知道它如何可以帮助，但随后下一次。顺便说一句即使是现在我不明白是怎么回事，与会话，但它的工作原理。

PS/ Firstly when I have seen this recommendation I did not understood how it can help but then next time when OAuth fails i just simply restarted WebApp and it starts working. By the way even now i dont understand what is going on with session but it works.
