如何从 ASP.NET MVC Web API 控制器返回 HTML?

How to return HTML from ASP.NET MVC Web API controller?

我尝试了下面的代码，但由于未定义 Response.Write 出现编译错误:

I tried the code below but got compile error since Response.Write is not defined:

public class MyController : ApiController
{
    [HttpPost]
    public HttpResponseMessage Post()
    {
        Response.Write("<p>Test</p>");
        return Request.CreateResponse(HttpStatusCode.OK);
    }
 }

推荐答案

ASP.NET Core.方法一

如果你的控制器扩展了 ControllerBase 或 Controller 你可以使用 Content(...) 方法:

ASP.NET Core. Approach 1

If your Controller extends ControllerBase or Controller you can use Content(...) method:

[HttpGet]
public ContentResult Index() 
{
    return base.Content("<div>Hello</div>", "text/html");
}

ASP.NET 核心.方法二

如果您选择不从 Controller 类扩展，您可以创建新的 ContentResult:

ASP.NET Core. Approach 2

If you choose not to extend from Controller classes, you can create new ContentResult:

[HttpGet]
public ContentResult Index() 
{
    return new ContentResult 
    {
        ContentType = "text/html",
        Content = "<div>Hello World</div>"
    };
}

传统的 ASP.NET MVC Web API

返回带有媒体类型text/html的字符串内容:

public HttpResponseMessage Get()
{
    var response = new HttpResponseMessage();
    response.Content = new StringContent("<div>Hello World</div>");
    response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");
    return response;
}
