从Umbraco 7.1.9升级到7.5.4的问题

Question

我在尝试通过Nuget或手动，合并文件等进行升级时遇到了问题。我最终得到的结论是，当我启动第一个网站时本地时间使用http://localhost:81（这在升级前工作正常），我不断收到下面的错误消息。

正在被重定向的URL如下：

http://localhost:81/install?redir=true&url=http%3a%2f%2flocalhost%3a81%2f

如果我尝试访问后端我也得到了同样的信息。我下载了一个Umbraco源代码的副本，并且在调试时可以在Umbraco.Web文件WebSecurity.cs中看到，方法IsAuthenticated（）对_httpContext.User显示为空。

任何想法可能是什么问题？

Answer 1

仔细检查web.config文件的成员资格提供程序部分是否已正确合并。我认为这些版本之间有一些用户更改，有些位稍有改变？我也会清除你的cookies，以防万一，因为有时我在升级后遇到了UmbracoContext cookies问题。

Answer 2

我遇到了同样的问题，想分享我的经验。

我发现问题是我使用自定义的UmbracoApplication实现来执行依赖注入。

我相信安装过程必须使用应用程序通常不使用的一些依赖项。

要解决此问题，我将Global.asax更改为默认的UmbracoApplication类。然后，数据库更新后，我切换回我的自定义类。

我确定有一个更好的方法来解决这个问题，但我想记录我发现的情况，以防万一有人遇到同样的问题，并希望找到正确的方向或快速修复。

我的代码如下：

<%-- Live App --%> 
<%@ Application Inherits="Foo.WebsiteUmbracoApplication" Language="C#" %> 
<%-- For Umbraco DB Updates --%> 
<%--<%@ Application Inherits="Umbraco.Web.UmbracoApplication" Language="C#" %>--%> 

using System; 
using System.Web.Http; 
using System.Web.Mvc; 
using Umbraco.Web; 

namespace Foo 
{ 
    public class WebsiteUmbracoApplication : UmbracoApplication 
    { 
     protected override void OnApplicationStarted(object sender, EventArgs e) 
     { 
      base.OnApplicationStarted(sender, e); 

      ConfigureDependencyInjection(); 
      ConfigureFormatters(); 
     } 

     private static void ConfigureDependencyInjection() 
     { 
      var container = UnityConfig.ConfiguredContainer; 
      // MVC 
      DependencyResolver.SetResolver(new Microsoft.Practices.Unity.Mvc.UnityDependencyResolver(container)); 
      // Web API 
      GlobalConfiguration.Configuration.DependencyResolver = new Unity.WebApi.UnityDependencyResolver(container); 
     } 

     private static void ConfigureFormatters() 
     { 
      var formatters = GlobalConfiguration.Configuration.Formatters; 
      formatters.Remove(formatters.XmlFormatter); 
     } 
    } 
}
