Use ControllerBase. Content() method returns a ContentResult object. This method has several overloads, and we will be using an overload that accepts two string parameters. The first string represents the content of the HTML while the last is the content-type which for HTML is "text/html" .
Returning html content from Web API can be very useful, when you want to provide content that can be embedded into html page easily.
You can use the Content method with the Content-Type text/html to return the HTML directly, without the need of Html. Raw . You can pass whatever Content-Type you want, such text/xml .
Learn the three ways you can return data from your ASP.NET Core Web API action methods. We have three ways to return data and HTTP status codes from an action method in ASP.NET Core. You can return a specific type, return an instance of type IActionResult, or return an instance of type ActionResult.
If your Controller extends ControllerBase or Controller you can use Content(...) method:
[HttpGet]
public ContentResult Index()
{
return base.Content("<div>Hello</div>", "text/html");
}
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>"
};
}
Return string content with media type text/html:
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;
}
Starting with AspNetCore 2.0, it's recommended to use ContentResult instead of the Produce attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885
This doesn't rely on serialization nor on content negotiation.
[HttpGet]
public ContentResult Index() {
return new ContentResult {
ContentType = "text/html",
StatusCode = (int)HttpStatusCode.OK,
Content = "<html><body>Hello World</body></html>"
};
}
