如何解决警告:“应用程序由于重定向而被评估为不健康".在Azure运行状况检查功能上 [英] How to fix warning: "Application evaluated unhealthy due to redirection." on Azure Health Check Feature

问题描述

我运行了诊断并解决问题"在其中一个应用程序服务中的Azure仪表板上，然后我收到此严重风险警报:由于重定向，应用程序评估为不健康."

建议的操作是:

 如果应用程序具有HTTP到HTTPS redirectoin，请考虑以下解决方案之一.一种.从TLS/SSL设置刀片中为相应的App Service启用仅HTTPs".这将强制运行状况检查ping超过443.b.修改应用程序逻辑/URL重写规则，以便来自用户代理的请求– ReadyForRequest/1.0 +(HealthCheck)&HealthCheck/1.0不会重定向. 

我已经按照(a)点的建议启用了仅HTTPs"，但我不知道如何执行(b)点.如何修改应用程序逻辑/广告和URL重写规则，以便来自用户代理的请求– ReadyForRequest/1.0 +(HealthCheck)& HealthCheck/1.0 是否未重定向?

当前，我启用运行状况检查并将运行状况检查"路径设置为/.

谢谢您的帮助.

解决方案

我下载了官方示例，并对代码进行了一些更改，希望对您有用.

示例代码---

我将在您的另一篇文章中添加方法2 .

I ran "Diagnose and solve problems" on Azure dashboard inside one of the app services, and then I got this critical risk alert: "Application evaluated unhealthy due to redirection.".

Recommended actions is:

If the application has HTTP to HTTPS redirectoin, consider one of the following solutions.

a. Enable 'HTTPs Only' from the TLS/SSL settings blade for the respective App Service. This will force health check pings to over 443.

b. Modify the Application logic/ad a URL Rewrite rule so that requests from the user agents – ReadyForRequest/1.0+(HealthCheck) & HealthCheck/1.0 are not redirected.

I already enable 'HTTPs Only' as suggested on point (a), but I don't know how to do point (b). How to modify the Application logic/ad a URL Rewrite rule so that requests from the user agents – ReadyForRequest/1.0+(HealthCheck) & HealthCheck/1.0 are not redirected ?

Currently, I enable Health Check and set the Health Check path to /.

Thanks before for any help.

解决方案

I download offical sample, and make some changes in code, hope it useful to you.

Sample Code --- .net core 3.X(HealthChecksSample)

Method 1.

Because the code is in .net core, I first recommend configuring rewrite in Startup.cs.

public void Configure(IApplicationBuilder app)
{
    app.UseHealthChecks("/");

    app.UseRouting();

    app.MapWhen(
        ctx => ctx.Request.Path.StartsWithSegments("/"),
        appBuilder =>
        {
            appBuilder.UseMiddleware<HealthCheckMiddleware>();
        }
    );

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapHealthChecks("/");

        endpoints.MapGet("/{**path}", async context =>
        {
            await context.Response.WriteAsync(
                "Navigate to /health to see the health status.");
        });
    });
}

It works for me, both in local and azure web app.

I will add Method 2 in your another post.
