Show Suggested Answer

Suggested Answer:

Scenario: The Web API must only accept one data format.
The MVC front-end layer and the Web API will communicate by using JSON.
The most common approach to support JSON only is to clear other formatters and leave only JsonMediaTypeFormatter around.
Given an instance of HttpConfiguration you'd simply clear all and re-add JsonMediaTypeFormatter: configuration.Formatters.Clear(); configuration.Formatters.Add(new JsonMediaTypeFormatter());

I think the answer is correct, but is not the full solution. The full solution is to remove all format first before adding only Json back. Given an instance of HttpConfiguration you'd simply clear all and re-add JsonMediaTypeFormatter: configuration.Formatters.Clear(); configuration.Formatters.Add(new JsonMediaTypeFormatter());

In https://docs.microsoft.com/de-de/aspnet/core/web-api/advanced/custom-formatters?view=aspnetcore-3.1 I found "The framework provides built-in input and output formatters for JSON and XML. " To fullfill the security requrement that only one media type is allowed and that the communication should be by JSON it shoud be 1. Formatter 2. Remove 3.Formatters 4.JsonFormatter
