Request BinaryRead in ASP.NET 5 (MVC6)

问题:

I had this code working in ASP.NET MVC 5, but I can't make it works in ASP.NET MVC 6 (ASP.NET 5)

Can someone help me?

public EmptyResult PayPalPaymentNotification(PayPalCheckoutInfo payPalCheckoutInfo)         
    { 
      PayPalListenerModel model = new PayPalListenerModel();             
      model._PayPalCheckoutInfo = payPalCheckoutInfo;               
      byte[] parameters = Request.BinaryRead(Request.ContentLength);

      if (parameters != null)             
      {                 
        model.GetStatus(parameters);             
      }

      return new EmptyResult();           
    } 

The error is in:

byte[] parameters = Request.BinaryRead(Request.ContentLength);

HttpRequest does not contain a definition for BinaryRead and no extension method BinaryRead accepting a first argument of type HttpRequest could be found (are you missing a using directive or an assembly reference?).

I have tested somethings like this, but not working:

HttpContext.Request.BinaryRead

Thanks.

回答1:

The HttpRequestFeature object now provides a body which is a stream. So this should work.

    public static byte[] ReadRequestBody(Stream input)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            input.CopyTo(ms);
            return ms.ToArray();
        }
    }

and then ...

 var paramArray = ReadRequestBody(Request.Body);
