App Insights 设置 Visual Studio SDK 未在门户上显示请求

Question

我有一个面向 .NET 4.8 的 ASP.NET Web API 项目。

在顶部，它添加了 ASP.NET Core 配置服务

Startup.cs

。

它有

Startup.cs

、配置服务、.NET 4.8 和

app.config

。 我在门户上创建了一个应用程序洞察资源。安装了

Microsoft.ApplicationInsights.AspNetCore

nuget 包，将门户 AI 资源检测密钥添加到

app.config

。

然后我使用 postman 向 API 发送请求，期望能够在 App Insights 上看到请求和分析器。运气不好！

 Startup.cs

Answer 1

仅几点。

1. 在这一行中：

services.AddApplicationInsightsTelemetry(Configuration);

传入Configuration对象有什么原因吗？通常，如果需要，我会传入 ApplicationInsightsServiceOptions() 类型的对象。否则我不会使用任何参数。

2. 您是否尝试过添加此行：

builder.Services.AddServiceProfiler()

您可能还需要添加对 Microsoft.ApplicationInsights.Profiler.AspNetCore Nuget 包的引用。
