How do I set or remove the Default Response Content Type Using SwashBuckle

问题

The default response content type when using SwashBuckle is text/plain. How can I change the default to be application/json or even remove text/plain?

回答1:

The response content of an end point is not determined by Swashbuckle but by the formatters set in the configuration of your ASP.NET Web API project.

To remove the text/plain content type and only support application\json you could add this to the Register method of your WebApiConfig:

GlobalConfiguration.Configuration.Formatters.Clear();

var jsonFormatter = new JsonMediaTypeFormatter();
jsonFormatter.SupportedMediaTypes.Clear();
jsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue('application\json'));

GlobalConfiguration.Configuration.Formatters.Add(jsonFormatter);
