Question

我需要构建一个html文档并将其返回到我的Web api中。网络和论坛上的所有可用答案均建议使用HttpResponseMessage。我想通过IHttpActionResult实现。以下是到目前为止的内容：

    [ResponseType(typeof(HttpResponseMessage))]
    public async Task<IHttpActionResult> GetNotesViewModels()
    {
        var note = await GetHtmlText();
        var response = new HttpResponseMessage();
        response.Content = new StringContent(note);
        response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");

        return Ok(ResponseMessage(response));
    }

我没有收到我想要的东西。这里缺少什么？

您可以实现自己的HtmlResult，如下所示（徒手）：

public class HtmlActionResult : IHttpActionResult
{
    public HtmlActionResult (HttpRequestMessage request, string content)
    {
        Request = request;
        Content= content;
    }

    public string Content { get; private set; }
    public HttpRequestMessage Request { get; private set; }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        return Task.FromResult(ExecuteResult());
    }

    public HttpResponseMessage ExecuteResult()
    {
        var response = new HttpResponseMessage();

        if (!string.IsNullOrWhiteSpace(Content))
            response.Content = new StringContent(Content, Encoding.UTF8, "text/html");

        response.RequestMessage = Request;
        return response;
    }
}

并像这样使用它：

   public async Task<IHttpActionResult> GetNotesViewModels()
    {
        var note = await GetHtmlText();
        return new HtmlActionResult(Request, note);
    }

如何使用IHttpActionResult接口从WebApi 2操作返回html文档？
