MVC 6更改返回内容类型 [英] MVC 6 change return content-type

问题描述

我似乎无法在新的Asp.net MVC 6中更改控制器方法的返回内容类型.

I seem to be unable to change the return content-type of my controller-method in the new Asp.net MVC 6.

我尝试了以下各种变化:

I tried various variations on:

Context.Response.Headers.Add("Content-type", "text/x-vcard");

在过去的WebApi时代，我可以使用它，并更改格式器:

In the old WebApi days I could use this, and change the formatter:

return Request.CreateResponse(HttpStatusCode.OK, data, JsonMediaTypeFormatter.DefaultMediaType);

我可以在MVC 6中做类似的事情吗?

Could I do something similar in MVC 6?

推荐答案

您可以通过在控制器操作上设置Produces("ResultType")属性来实现.例如:

You can do that by setting the Produces("ResultType") attribute on the controller action. For example:

[Produces("application/xml")]
public Object Index()
{
    return new { Id = 100 };
}

给定结果类型的formatter将用于转换object，而与Accept Header无关.

The formatter for the given result type will be used to convert the object, regardless of the Accept Header.

但是您需要为响应类型注册一个formatter.因此，如果要使用"text/x-vcard"，则必须为此创建一个格式化程序.

But you need to have a formatter registered for the response type. So if you want to use "text/x-vcard", you'd have to create a formatter for that.

为此，您需要创建一个实现IOutputFormatter的类，并在Startup.cs中的ConfigureServices()方法中将其注册，如下所示:

To do that you need to create a class that implements IOutputFormatter and register it in Startup.cs in the ConfigureServices() method like this:

services.Configure<MvcOptions>(options =>
{
    options.OutputFormatters.Add(new VCardFormatter());
});
