为 Azure MVC Web 应用程序获取应用程序 URL 以与 webhook 一起使用

Question

I need to transer the URL of my web app to an external API. The app is an ASP.NET web app. Can I use the Azure SDKs to obtain this URL somehow?

This happens on app startup, so I do not have access to any request context.

You can utilize UriHelper class of the HTTP Extension library, For dot net core you can find the definition here:

https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.http.extensions.urihelper?view=aspnetcore-3.0

UriHelper.GetDisplayUrl(HttpRequest) Method

Returns the combined components of the request URL in a fully un-escaped form (except for the QueryString) suitable only for display. This format should not be used in HTTP headers or other HTTP operations.

UriHelper.GetEncodedUrl(HttpRequest) Method

Returns the combined components of the request URL in a fully escaped form suitable for use in HTTP headers and other HTTP operations.

https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.http.extensions.urihelper?view=aspnetcore-2.1

Hope it helps.
