Question

我在尝试通过Nuget升级或手动合并，合并文件等后出现问题。我最终得到一个点，当我第一次使用http://localhost:81本地启动网站时（这有效）升级之前很好），我一直收到下面的错误信息。

重定向到的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，我也会收到相同的消息。我下载了Umbraco源代码的副本，调试后可以在Umbraco.Web的WebSecurity.cs文件中看到，方法IsAuthenticated（）为_httpContext.User显示为null。

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，有些位略有变化？我也会清除你的cookie，以防万一，因为有时我在升级后遇到了UmbracoContext cookie的问题。

Answer 2

我遇到了同样的问题，想分享我的经验。

我发现问题在于我使用自定义popup = QtGui.QTextEdit() popup.setMinimumSize(1400, 1000) popup.show()实现进行依赖注入。

我认为安装过程必须使用应用程序通常不会使用的某些依赖项。

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

我确定有更好的方法可以解决这个问题，但我想记录一下我发现的情况，以防有人遇到同样的问题，并希望能够走上正轨或快速解决问题。

我的代码如下：

UmbracoApplication

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

从Umbraco 7.1.9升级到7.5.4
