健康检查失败- TLS上的HTTP/2不是在HTTP/2唯一的端点上协商的

Question

我只为我的API启用了HTTP2 2。但是，在尝试使用健康检查时，我会得到以下错误

TLS上的HTTP/2不是在HTTP/2唯一的端点上协商的。

安装程序如下所示

"Kestrel": {
"EndpointDefaults": {
  "Protocols": "Http2",
  "Http": {
    "Url": "http://localhost:5020"
  }
}

},

健康检查：

public static IServiceCollection AddCustomHealthCheck(this IServiceCollection services)
{
    var sqlOptions = services.GetOptions<SqlOptions>("ConnectionStrings");
    var rabbitMqOptions = services.GetOptions<RabbitMqOptions>("RabbitMq");

    services.AddHealthChecks()
        .AddSqlServer(sqlOptions.DefaultConnection)
        .AddRabbitMQ(rabbitConnectionString:
            $"amqp://{rabbitMqOptions.UserName}:{rabbitMqOptions.Password}@{rabbitMqOptions.HostName}");

    services.AddHealthChecksUI(setup =>
    {
        setup.SetEvaluationTimeInSeconds(60); // time in seconds between check
        setup.AddHealthCheckEndpoint("Basic Health Check", "/healthz");
    }).AddInMemoryStorage();

    return services;
}

public static WebApplication UseCustomHealthCheck(this WebApplication app)
{
    app.UseHealthChecks("/healthz",
            new HealthCheckOptions
            {
                Predicate = _ => true,
                ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse,
                ResultStatusCodes =
                {
                    [HealthStatus.Healthy] = StatusCodes.Status200OK,
                    [HealthStatus.Degraded] = StatusCodes.Status500InternalServerError,
                    [HealthStatus.Unhealthy] = StatusCodes.Status503ServiceUnavailable
                }
            })
        .UseHealthChecksUI(options =>
        {
            options.ApiPath = "/healthcheck";
            options.UIPath = "/healthcheck-ui";
        });

    return app;
}

我通过告诉健康检查客户端具体使用HTTP2.0版本和下面的代码来解决这个问题。

        services.AddHealthChecksUI(setup =>
        {
            setup.ConfigureApiEndpointHttpclient((sp, client) =>
            {
                client.DefaultRequestVersion = new Version(2, 0);
            });
            setup.SetEvaluationTimeInSeconds(60); // time in seconds between check
            setup.AddHealthCheckEndpoint("Basic Health Check", "/healthz");
        })
        .AddInMemoryStorage();
