Net核心Web应用程序中不同端口上的运行状况检查 [英] Healthchecks on different port in Net core Web application

问题描述

我有一个带有API的标准Net核心Web应用程序.我正在尝试实施运行状况检查，但希望它在其他端口上运行.

I have a standard Net core web application with an API. I'm trying to implement healthcheck, but want it to run on a different port.

在配置"中:

app.UseHealthChecks("/health", 8000);

在ConfigureServices中

In ConfigureServices

services.AddHealthChecks()

默认情况下，可以通过以下方式访问api: https://localhost:44322/api/values

By default, the api is accessible via: https://localhost:44322/api/values

然后我希望可以通过以下方式访问运行状况检查: https://localhost:8000/health

And I then expect the healthcheck to be accessible via: https://localhost:8000/health

如果我移除端口，则恢复正常.我是否需要其他配置才能将应用程序设置为在不同端口上运行?

The healh works good if I remove the port. Do I need some other configuration to setup the application to run on different ports?

推荐答案

As requested, I'm creating an answer so future readers can benefit from.

最初的问题是因为您没有在应用程序中注册运行状况检查端口 8000 .有两种方法可以做到这一点.

The initial problem was because you were not registering the health check port 8000 in your app. There are two ways to do this.

1. 通过在 launchSettings.json 中设置端口，该端口由

1. By setting the port in launchSettings.json which is picked up by the Environment Variables Configuration Provider

或者按照我在注释中的建议，在 Program.cs 中调用 UseUrls 并直接在其中指定HealthCheck端口以及您的应用程序端口.像这样的东西:

Or as I suggested in the comments, call UseUrls in Program.cs and specify the HealthCheck port directly there, along with the ones for your app. Something like this:

return new WebHostBuilder()
    .UseConfiguration(config)
    .UseUrls("http://localhost:5000/;http://localhost:8000")
    .UseKestrel()
    .UseStartup(startupType)
    .Build();

其中 5000 是您的常规App端口，而 8000 是HealthCheck端口.

Where 5000 is your normal App port, and 8000 is the HealthCheck one.

然后在 Startup.cs 的 Configure 中，直接使用端口:

Then inside Configure in Startup.cs you use the port directly:

app.UseHealthChecks("/health", port: 8000);

您可以在官方文档中找到所有这些以及更多内容:

You can find all of this and more in the official docs: Health checks in ASP.NET Core - Filtering by Port
