asp.net-core-1.1 - ASP.Net Core 1.1 MiddleWare 响应

Question

我正在用中间件服务替换 HttpHandler。除了返回实际图像外，我的所有代码都在工作。所有现有示例都是针对 asp.net Core（或更早版本）的，但是对于 asp.net core 1.1，响应对象是否发生了变化？

public async Task Invoke(HttpContext context)
{
      var mediaType = new MediaTypeHeaderValue("image/jpeg");
      mediaType.Encoding = System.Text.Encoding.UTF8;
      context.Response.ContentType = mediaType.ToString();
      byte[] results = some process that generates a byte array
      Stream stream = new MemoryStream(results);
      context.Response.Body = stream;
      await _next.Invoke(context);
 }

那么我们如何将字节数组附加到响应对象上呢？

There is couple of methods which you can use on .NET Core 1.1:

httpContext.Response.Body.WriteAsync([BUFFER], [OFFSET], [COUNT]);
httpContext.Response.Body.Write([BUFFER], [OFFSET], [COUNT]);
httpContext.Response.Body.WriteByte([BYTE]);
httpContext.Response.WriteAsync([TEXT])
