ASP.NET WEB API, unwanted parameters in request

问题

I'm using asp.net web api. I have a method in UserController which receives POST-requests:
void Post([FromBoby] UserInfo userInfo)

I have a model UserInfo with fields: Login, Name.

I can post json: {Login:"someLogin", Name:"someName"} and it will successfully mapped to userInfo parameter.

I can also post json: {Login:"someLogin", Name:"someName", UnwantedParameter:"someString"} which will also ssuccessfully mapped to UserInfo parameter and UnwantedParameter will be ignored.

How to handle 'unwanted' parameters to throw response exception?

Take a look at this question, I believe you are asking the same thing:

POST object in .NET WebAPI

At the end of the day, they suggest setting the following property (typically in the Global.asax.cs)

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.MissingMemberHandling = MissingMemberHandling.Error;
