首先,asp.net 5 没有了 MVC 和 WebApi 的区分,都属于 ASP.NET 5,从 Controller 的继承就可以看出,原来 ASP.NET WebApi 2 ValuesController : ApiController
改成了 ValuesController : Controller
,并且返回 HttPResponseMessage 也有些改变。
ASP.NET WebApi 2 中的示例代码:
[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 中的示例代码:
[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);}
可以看到,改变还是很大的,主要是两方面:
Request.CreateResponse
,获取 Accept 需要通过 Request.GetTypedHeaders()
。Response.Body
中。参考资料:
