Adds sony/gobreaker as a wrapper for the rest client.
It's a rest client that also supports x-www-form-urlencoded.
This library adds another wrapper to the rest client which provides a circuit breaker.
We currently use sony/gobreaker, which is a very lightweight implementation with a small dependency footprint (MIT licensed).
Change the setup of your rest client like this:
// [...]
var circuitBreakerName string = "some-name"
var maxNumRequestsInHalfOpenState uint32 = 100
var counterClearingIntervalWhileClosed time.Duration = 5 * time.Minute
var timeUntilHalfopenAfterOpen time.Duration = 60 * time.Second
var requestTimeout time.Duration = 15 * time.Second
circuitBreakerClient := aurestbreaker.New(httpClient, circuitBreakerName, maxNumRequestsInHalfOpenState, counterClearingIntervalWhileClosed, timeUntilHalfopenAfterOpen, requestTimeout)
You should usually insert the cbClient above the request logger and below the retryer.
This library uses the StephanHCB/go-autumn-logging api for logging framework independent logging.
If you are writing a library, do NOT import any of the go-autumn-logging-* modules that actually bring in a logging library. You will deprive application authors of their chance to pick the logging framework of their choice.
In your testing code, call aulogging.SetupNoLoggerForTesting() to avoid the nil pointer dereference.
If you are writing an application, import one of the modules that actually bring in a logging library, such as go-autumn-logging-zerolog. These modules will provide an implementation and place it in the Logger variable.
Of course, you can also provide your own implementation of the LoggingImplementation interface, just
set the Logger global singleton to an instance of your implementation.
Then just use the Logger, both during application runtime and tests.
