How to get raw request body in ASP.NET?

Question

In the HttpApplication.BeginRequest event, how can I read the entire raw request body? When I try to read it the InputStream is of 0 length, leadin

Answer 1

The request object is not populated in the BeginRequest event. You need to access this object later in the event life cycle, for example Init, Load, or PreRender. Also, you might want to copy the input stream to a memory stream, so you can use seek:

protected void Page_Load(object sender, EventArgs e)
{
    MemoryStream memstream = new MemoryStream();
    Request.InputStream.CopyTo(memstream);
    memstream.Position = 0;
    using (StreamReader reader = new StreamReader(memstream))
    {
        string text = reader.ReadToEnd();
    }
}
