Abstractions - Core MVC extensibility
Controllers - MVC implementations of .Abstractions and supporting
contracts
Infrastructure - General purpose support APIs. Metadata APIs that don't
fit clearly with a feature or with .Abstraction
ActionBindingContext
This change replaces IScopedInstance<T> in favor or IActionContextAccessor
and IActionBindingContextAccessor. In the spirit of IHttpContextAccessor,
these are both singletons which use AsyncLocal for storage.
This change allows the invoker factory to be cached which results in some
significant perf gains.
Also ensures that when a type is marked as skipped, any sub property which is model bound (and hence a modelstate un validated entry),
is marked as skipped (otherwise it would cause the ModelState to be invalid).
Also fixing a bug in model state dictionary FindKeyWithPrefix was not considering [0] & [0][0] as a valid prefix.
Covers simple scenario for each model binder.
Covers scenarios mixing a POCO model binder -> Simple Model binder.
This contains tests for
HeaderModel
ServicesModelBinder
CancellationTokenModelBinder
ByteArrayModelBinder
FormFileModelBinder
Part 2 Will contain similar tests for
FormCollectionModelBinder
BinderTypeBasedModelBinder
TypeConverterModelBinder
TypeMatchModelBinder
Any leftovers for BodyModelBinder
Consider
public class Person
{
[FromBody]
public Address Address { get; set; }
}
public class Address
{
[Required]
public string Street { get; set; }
public int Zip { get; set; }
}
Request body { "Zip" : 12345 }
In this case the error key would be "prefix.Address.Street" (assuming there is a prefix because of additional metadata/positioning for/of the Person model).
public class Person
{
[Required]
public string Name { get; set; }
}
public void Action([FromBody]Person p)
{
}
Request body { }
In this case the prefix gets ignored and the error key is Name.
Please note this is so that we are compatible with MVC 5.0
public class Person
{
[Required]
public string Name { get; set; }
}
public void Action([FromBody][ModelBinder(Name = "prefix")] Person p)
{
}
public void Action2([FromBody][Bind(Name = "prefix")] Person p)
{
}
Request body { }
In both these cases (Action and Action2) the prefix gets ignored and the error key is Name.
This is a slight improvement from mvc, as in MVC the action parameter would be null.
The followup for this would be to fix#2416 -
This PR ignores the validation assuming that #2416 will address the issues and update the test.
NOTE: previous versions of mvc did not have property binding and hence there is no precedence in this case. For MVC and Web API it was possible to body bind an action parameter which used an empty prefix instead of a parameter name for adding errors to model state (In case of MVC if a custom prefix was provided, it failed binding from body i.e the parameter was null).
