About

This package contains ActionExecutingContext extensions for validation URL parameters together with Body, Form and Query model validation.

• If an id in URL posts/{id}/pages is empty, an endpoint returns Not Found response.
• If a model next to [FromBody], [FromForm] or [FromQuery] is not valid, an endpoint returns Bad Request response with ValidationProblemDetails model. It uses FluentValidation (https://github.com/FluentValidation/FluentValidation) for validating models.

How To Use

• Create FluentValidation model validator in accordance with documentation https://docs.fluentvalidation.net/en/latest/start.html.

• Register created validator

builder.Services.AddScoped<IValidator<BodyModel>, BodyModelValidator>();

or register all created validators from the same assembly

builder.Services.AddValidatorsFromAssemblyContaining<BodyModelValidator>();

• The package contains ApiRequestValidation attribute, which can be set on a controller or its method.

[ApiRequestValidation]
public class MyController : Controller
{
}

or

public class MyController : Controller
{

    [ApiRequestValidation]
	[HttpPost("posts/{id}/pages")]   
    public async Task<IActionResult> Create(string id, [FromBody] BodyModel body, [FromQuery] QueryModel query)
    {
        ...
    }

}
