禁用自定义活页夹的 model 验证

Question

I have created a custom model binder and would like to disable model validation. How to do that?

   public class ConverterModelBinder : IModelBinder
    {
        public Task BindModelAsync(ModelBindingContext bindingContext)
        {
            ///...creating and binding ConversionModel 
            bindingContext.Result = ModelBindingResult.Success(ConversionModel );

            return Task.CompletedTask;
        }
}

The controller action is never executed because build in model validator kicks in for my ConversionModel object. I don't want to validate it.

public async Task<ActionResult> Convert([ModelBinder(typeof(ConverterModelBinder))] ConversionModel model, CancellationToken cancellationToken)
        {
        }

Answer 1

You can try to use the following methods to disable model validation:

Method 1: Use the ValidateNever attribute:

[ValidateNever]
public class ConversionModel {
   //... properties
}

Method 2: Set the ApiBehaviorOptions.SuppressModelStateInvalidFilter Property to true :

builder.Services.Configure<ApiBehaviorOptions>(options =>
{
    options.SuppressModelStateInvalidFilter = true;
});
