Validating query arguments of type array

[tyamahori]

ref #181

Hi.

this pr makes it possible to accept query arguments of an array.

For example.

https://example.com?someKey[]=value1&someKey[]=value2

We will be able to validate someKey[].

I approve by mistake!

@tyamahori Hi, same question as here #162 (comment)

Isn't this notation valid only in deepObject serialization form ? I think we need to check this explicitly here

@scaytrase
Hi, thank you for your comment.

This notation is valid if a query string is paramName[]=value1&paramName[]=value2&....

deepObject – simple non-nested objects are serialized as paramName[prop1]=value1&paramName[prop2]=value2&.... The behavior for nested objects and arrays is undefined.

Do you mean, you think paramName[prop1]=value1&paramName[prop2]=value2&.... should be checked ?

no, I mean that deafult serealization method is form + explode which clearly shows the example for array values

/users?id=3&id=4&id=5

So if you want to provide query args in another format - you should specify another serialization style in your schema. From given styles I see deepObject as the most suitable one here

https://swagger.io/docs/specification/serialization/

They specify n\a for array example for deepObject, but I think prop[]=val1&prop[]=val2 notation is OK here

Spec for test doesn't match test data
