HealthCheck

Question

Hi All,

I want to call an API method of same project via CheckHealthAsync.

any help!

private readonly ISampleService _sampleService;

public async Task<HealthCheckResult> CheckHealthAsync(HealthCheckContext context,
CancellationToken cancellationToken = new())
{
try
{
var result = await _sampleService.GetName() // Need to implement the code for call.

// If we get the result then it's healthy
}
catch (Exception ex)
{

}

Sure, I can help with that. You can call the GetName method from _sampleService inside the CheckHealthAsync method and return a HealthCheckResult based on the result of the GetName method. Here’s how you can do it: public async Task CheckHealthAsync(HealthCheckContext context, CancellationToken cancellationToken = new()) { try { var result = await _sampleService.GetName(); // Call to GetName method // If we get the result then it's healthy if (!string.IsNullOrEmpty(result)) { return HealthCheckResult.Healthy("The check indicates a healthy result."); } else { return HealthCheckResult.Unhealthy("The check indicates an unhealthy result."); } } catch (Exception ex) { return HealthCheckResult.Unhealthy("The check indicates an unhealthy result.", ex); } } In this code, if the GetName method returns a non-null or non-empty string, the health check is considered Healthy. If the GetName method returns null or an empty string, or if an exception is thrown, the health check is considered Unhealthy. The exception is also passed to the Unhealthy method so that it can be logged for debugging purposes. Please replace the string messages with the appropriate ones for your application. Thanks
