为什么Azure Active Directory身份验证会在ASP.NET Core应用程序中引起字符编码错误?

[英]Why is Azure Active Directory Authentication causing an character encoding error in my ASP.NET Core Application?

我有一个正在制作的ASP.NET Core 2.2应用程序,它使用KendoUI作为其框架的一部分。 我最近设置了应用程序的骨骼,然后使用Visual Studio 2019的内置向导添加了Azure Active Directory身份验证。 这在Azure中为我创建了一个应用程序注册,该注册将根据我公司的活动目录对用户进行身份验证。

问题是,当我现在运行我的应用程序时,出现以下错误并且没有页面加载:

未声明纯文本文档的字符编码。 如果文档包含来自US-ASCII范围之外的字符,则在某些浏览器配置中,文档将呈现乱码。 需要在传输协议中声明文件的字符编码,或者文件需要使用字节顺序标记作为编码签名。

对该消息的进一步调查显示了更多详细信息,这些细节是:

加载此URI时出错:协议错误(unknownError):无法为https:// localhost:44379 /加载源。 [异常...“组件返回的失败代码:0x80470002(NS_BASE_STREAM_CLOSED)[nsIInputStream.available]” nsresult:“ 0x80470002(NS_BASE_STREAM_CLOSED)”“位置:” JS框架:: resource://devtools/shared/DevToolsUtils.js :: onResponse ::“ 555行”数据:否]堆栈:onResponse @ resource://devtools/shared/DevToolsUtils.js:555:34 onStopRequest @ resource://gre/modules/NetUtil.jsm:123:17行:555,列:0

我查看了添加AAD期间受影响的所有内容,并且项目中的以下文件已更改。

  • appSettings.json
  • 启动文件
  • 扩展名(文件夹)
  • [Authorise]放置在HomeController.cs
  • AzureAD(文件夹)

之前在我的应用程序中使用过AAD之后,我希望看到这些文件已更改,但是以后运行该应用程序时我从未遇到任何问题。 我开始研究可能引起问题的更改。 经过一些工作后,我意识到,如果我从控制器中删除[Authorize] ,则一切正常。

我猜这可能是我的应用程序注册中潜在的路由问题? 我不确定,我需要一些帮助,因为该消息有点像是红色鲱鱼,因为它表明存在HTML格式问题。 对于发生了什么问题,我需要一些指导。

这是我的代码和项目结构。

结构体

我总是将UI与类库分开,因为AAD不会更改Data,Repo或Services库中的文件,为简洁起见,我不会在此问题中包括它们。

因此,这是与AAD直接相关的代码,我不确定这是路由问题还是应用注册的不正确配置。 我需要一些帮助。

如果您可以重现此错误,则可以将其作为产品错误报告给AAD团队。 如果您要连接到其他服务(例如Azure SQL)并且连接存在问题,有时会发生此错误。 您是否还有其他错误日志?

如果您想获得支持票,请随时通过AzCommunity@microsoft.com与我联系,我可以为您开箱。
