在 ASP.NET Core 中使用默认方案注册身份验证方案时，Application Insights 中的 pageViews 停止记录

Question

我的 Asp.Net Core 应用程序已正确登录到 Application Insights 中的请求和页面视图。

但是，当我这样做时，它会停止记录页面视图（尽管记录了请求）：

  services.AddAuthentication("MyScheme");

但是，请注意，如果我这样做（不指定默认方案），那么页面视图会正常记录：

  services.AddAuthentication();

有人可以解释一下使用默认方案的 AddAuthentication 如何干扰 pageViews 日志记录吗？

Answer 1

即使在使用默认方案注册身份验证方案后，我也可以记录我的 WebApp 的 Pageview。

当我尝试访问时

builder.Services.AddAuthentication()

我收到以下错误

InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found. The default schemes can be set using either AddAuthentication(string defaultScheme) or AddAuthentication(Action<AuthenticationOptions> configureOptions).

我已设置身份验证方案如下

builder.Services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)

检查以下解决方法以配置 ApplicationInsights 并记录页面浏览量

我能够在本地和从部署的 Azure 应用服务中进行日志记录。

我已引用 Microsoft Application Insights JavaScript SDK 来记录页面视图。

在

_ViewStart.cshtml

文件中，在

Views

文件夹下编写以下脚本。
