c# - 在 Startup.cs 的 Configure 中获取域名或主机名和端口

Question

我需要帮助获取我的应用程序的主机名/域名和端口。

到目前为止，这是我在 Startup.cs 中的 Configure 方法中的示例代码:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    var url = ""; // something that will get the current host/domain and port of the running applicaiton.

    RecurringJob.AddOrUpdate<ISomething>(i=>i.SomethingToExecute(url), Cron.Daily);
}

因为我需要将 url 字符串传递给我的 SomethingToExecute 方法

public class Something : ISomething 
{
    public void SomethingToExecute(string url){
        ... 
        Debug.WriteLine(url)
    }
}

根据这个Github Issue以及 ASP.NET Core 团队的回应:

It's not possible. You need to read this information directly from config. The server does not read the endpoint configuration until it's ready to start the application (after Startup). Even then, that information would be inaccurate much of the time due to reverse proxy setups like IIS, Nginx, docker, etc..
