发布并通过身份验证后，ASP.NET MVC Web应用程序重定向到localhost

Question

我正在尝试使用Azure Active Directory进行身份验证来创建带有身份验证的简单MVC Web应用程序。 我使用了Visual Studio 2017中的连接服务向导来为我执行此操作。 我目前的问题是，一切都可以在我的本地计算机上正常运行，并且我能够登录，重定向到Web应用程序的索引页面并能够注销。 但是，当我发布此应用程序时，将重定向到localhost： https：// localhost：44389 /而不是Web App的索引页。

1. 将Startup.Auth.cs中app.UseOpenIdConnectAuthentication（）方法中的PostLogoutRedirectUri更改为指向：

“ https://CU-kvtest.azurewebsites.net/ ”

这没有用，仍然转到了本地主机。

2.更改Web.Config文件中的PostLogoutRedirectUri，使其指向“ https://CU-kvtest.azurewebsites.net/ ”。 那也不起作用，仍然去了本地主机

3. 转到Azure门户并转到名为ContosoUniversity2的Azure Active Directory（这是我正在使用的目录的名称），并将redirectURI更改为“ https://CU-kvtest.azurewebsites.net/ ”，这开始导致其他事宜。 我设置了一个密钥库，可以安全地获取我的connectionString，现在这个问题开始了：

因此，这种尝试也是失败的。

4. 然后，我在Azure门户中访问了已发布的应用程序服务，并添加了两个应用程序设置：

ida：PostLogoutRedirectUri =“ https://CU-kvtest.azurewebsites.net/ ”“ PostLogoutRedirectUri =” https://CU-kvtest.azurewebsites.net/“

那也不起作用，只会再次将我指向localhost。

我真的迷失了我还能做些什么。 我不明白我在做什么错...

Answer 1

1. 将PostLogoutRedirectUri更改为web.config文件中的Web应用程序站点URL。

2. 配置您的AAD应用程序。 将重定向URL更改为您的Web应用程序站点URL。

3. 重建并重新发布您的Web应用程序。

4. 在Azure门户上重新启动Web应用。

Answer 2

没有使用Azure，但是我的VPS上存在类似的问题。 我的问题原来是我在_Layout部分视图中设置了以下内容：

<BASE href=http://localhost:52549>

将本地主机更改为我的应用程序路径已将其修复
