ASP.NET 5 WebApi 返回 HttpResponseMessage - xishuai－IT工程師數位筆記本

首先，ASP.NET 5 沒有了 MVC 和 WebApi 的區分，都屬于 ASP.NET 5，從 Controller 的繼承就可以看出，原來 ASP.NET WebApi 2 ValuesController : ApiController 改成了 ValuesController : Controller，并且返回 HttpResponseMessage 也有些改變。

ASP.NET WebApi 2 中的示例代碼：

[Route("values/{id}")]
public async Task<HttpResponseMessage> Get(string id)
{
    var response = Request.CreateResponse(HttpStatusCode.OK);
    var accept = Request.Headers.Accept;
    var result = await _valuesService.Get(id);

    if (accept.Any(x => x.MediaType == "text/html"))
    {
        response.Content = new StringContent(result, Encoding.UTF8, "text/html");
    }
    else
    {
        response.Content = new StringContent(result, Encoding.UTF8, "text/plain");
    }
    return response;
}

ASP.NET 5 WebApi 中的示例代碼：

[Route("values/{id}")]
public async Task Get(string id)
{
    var accept = Request.GetTypedHeaders().Accept;
    var result = await _valuesService.Get(id);
    var data = Encoding.UTF8.GetBytes(result);
    if (accept.Any(x => x.MediaType == "text/html"))
    {
        Response.ContentType = "text/html";
    }
    else
    {
        Response.ContentType = "text/plain";
    }
    await Response.Body.WriteAsync(data, 0, data.Length);
}
