{services.AddHealthChecks();services.AddControllers();
}
然后修改Configure方法使用中间件:public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{ app.UseEndpoints(endpoints {endpoints.MapControllers();endpoints.MapHealthChecks(/health);});
}
现在准备工作完成运行程序然后访问 /health, 您将看到下边结果HealthCheckService.NET Core提供了一个HealthCheckService类我们可以把健康检查的放到我们的控制器中就像这样public class HealthController : ControllerBase
{private readonly ILoggerHealthController _logger;private readonly HealthCheckService _healthCheckService;public HealthController(ILoggerHealthController logger,HealthCheckService healthCheckService){_healthCheckService healthCheckService;_logger logger;}[HttpGet]public async TaskIActionResult Get(){var report await _healthCheckService.CheckHealthAsync();return report.Status HealthStatus.Healthy ? Ok(report) :StatusCode((int)HttpStatusCode.ServiceUnavailable, report);}
}
现在如果您尝试访问/health您将看到相同的结果。接下来我们将实现数据库运行状态检查EntityFramework Core 健康检查首先还是需要安装Microsoft.Extensions.Diagnostics.HealthChecks.EntityFrameworkCore到我们的项目中。接下来我们拿到数据库上下文然后修改代码public void ConfigureServices(IServiceCollection services)
{services.AddControllers();services.AddApiVersioning();
}
然后运行程序现在访问 /health 返回的结果是这样IHealthCheck一些情况下默认的健康检查可能不满足我们的需求那么可以继承 IHealthCheck 接口自定义我们的健康检查的逻辑。public class ApiHealthCheck : IHealthCheck
{private readonly IHttpClientFactory _httpClientFactory;public ApiHealthCheck(IHttpClientFactory httpClientFactory){_httpClientFactory httpClientFactory;}public async TaskHealthCheckResult CheckHealthAsync(HealthCheckContext context,CancellationToken cancellationToken default){using (var httpClient _httpClientFactory.CreateClient()){var response await httpClient.GetAsync(https://your-api-service.endpoint);if (response.IsSuccessStatusCode){return HealthCheckResult.Healthy($API is running.);}return HealthCheckResult.Unhealthy(API is not running);}}
}
然后修改代码如下public void ConfigureServices(IServiceCollection services)
{services.AddHealthChecks().AddDbContextCheckWeatherForecastDbContext().AddCheckApiHealthCheck(ApiHealth);services.AddControllers();
}
然后运行程序访问 /health,结果如下原文作者: Anuraj 原文链接 https://dotnetthoughts.net/implementing-health-check-aspnetcore/[1]最后欢迎扫码关注我们的公众号 【全球技术精选】专注国外优秀博客的翻译和开源项目分享也可以添加QQ群 897216102References[1] https://dotnetthoughts.net/implementing-health-check-aspnetcore/: https://dotnetthoughts.net/implementing-health-check-aspnetcore/
