Building resilient applications with Polly | El Vany dev You can implement those capabilities by applying Polly policies such as Retry, ⦠To handle various exceptions, you need to create one Policy for ⦠Polly To implement the retry policy with Polly, we will tell it to handle an HttpResponseMessage result on which we will check the IsSuccessStatusCode property to determine whether the request was successful or not. If IsSuccessStatusCode is true, the request was successful. Otherwise, it was not. Changing this to use Polly, I first create a policy. The policy handles any exception of type ContentfulException, where the StatusCode is 404. Polly â A .NET resilience and transient-fault-handling library We are using Polly to build policies. To try it for an infinite number of times, the Policy section needs to be replaced with the below lines - Policy.Handle() .RetryForever() .Execute(TestMethod); This will end up retrying until the code succeeds. I'm sure it will integrate even more conveniently with a few smart Extension Methods to abstract away the hard parts so we can fall into the "pit of success." Polly targets .NET Standard 1.1 (coverage In the past two years, Polly has been downloaded over 16 million times, and it's easy to see why. HTTP (s) request. There is ⦠Build Resilient Microservices (Web API) using Polly Briefly introduce Shao's lightweight fault handling library Polly Polly Is a .NET elastic and transient fault handling library. This can be done by providing the according type arguments and combining them using ⦠var policy = Policy .Handle() ⦠Optionally ⦠There isn't currently a way to define a Policy that handles a variety of different exceptions in a variety of different ways, all in one single fluent statement. However, the Polly Roadmap envisages the Polly Pipeline, which would allow any number of functionally-composed policies to be reduced to one Policy, thus: Allows us to execute strategies such as retries, circuit breakers, timeouts, ⦠Itâs this context that weâll use to pass a reference to the ILogger for our Controller class, into the policy being â¦
