Centeva.RequestValidation 2.0.0

Centeva Request Validation

Centeva.RequestAuthorization is a .NET library that provides a method for validating MediatR requests using FluentValidation. This enables validation at the request level instead of inside ASP.Net Core controllers, separating validation logic from the presentation layer.

Built With

• .NET
• MediatR
• FluentValidation

Installation

Import the Centeva.RequestValidation package to your projects where needed.

Dependency Injection

Register the validators and add a MediatR pipeline behavior in your Program.cs:

builder.Services.AddRequestValidation(typeof(SampleValidator).Assembly);

NOTE: If you're also using Centeva.RequestAuthorization, you likely want to call the above method first, then add the Authorization behavior. This ensures that validation happens first in your MediatR pipeline.

Validating a Request

To validate a request, add a validator class to your project that inherits from AbstractValidator<TRequest>, where TRequest is the type of request you want to validate. For example:

public class SampleValidator : AbstractValidator<SampleRequest>
{
    public SampleValidator()
    {
        RuleFor(x => x.Name).NotEmpty();
    }
}

If validation fails, a ValidationException will be thrown. Your application is responsible for handling those exceptions, possibly by mapping to a custom HTTP response or a ProblemDetails object.
