hpack
Header Compression for HTTP/2 written in C#
An Example on how to use the hpack.Encoder and hpack.Decoder
First, you have to create a HeaderListener that implements IHeaderListener
using System;
using System.Text;
namespace HTTP2
{
public class EmitHeaderEventArgs : EventArgs
{
private string _name;
private string _value;
public string Name { get { return this._name; } }
public string Value { get { return this._value; } }
public EmitHeaderEventArgs(byte[] name, byte[] value)
{
this._name = Encoding.UTF8.GetString(name);
this._value = Encoding.UTF8.GetString(value);
}
public EmitHeaderEventArgs(string name, string value)
{
this._name = name;
this._value = value;
}
}
public class HeaderListener : hpack.IHeaderListener
{
public delegate void EmitHeaderEventHandler(object sender, EmitHeaderEventArgs e);
public event EmitHeaderEventHandler HeaderEmitted;
public HeaderListener()
{
}
protected virtual void OnHeaderEmitted(EmitHeaderEventArgs e)
{
if (this.HeaderEmitted != null) {
this.HeaderEmitted(this, e);
}
}
public void AddHeader(byte[] name, byte[] value, bool sensitive)
{
this.OnHeaderEmitted(new EmitHeaderEventArgs(name, value));
}
}
}
Then you can instantiate this HeaderListener and add an EventListener
using System;
namespace HTTP2
{
class MainClass
{
public static void Main(string[] args)
{
var headerListener = new HeaderListener();
headerListener.HeaderEmitted += (object sender, EmitHeaderEventArgs e) {
Console.WriteLine("header emitted => name: " + e.Name + "; value: " + e.Value);
};
}
}
}
Now you can encode and decode headers
...
hpack.Encoder hpackEncoder = new hpack.Encoder(4096);
hpack.Decoder hpackDecoder = new hpack.Decoder(8192, 4096);
using(var binWriter = new BinaryWriter(new MemoryStream())) {
hpackEncoder.EncodeHeader(binWriter, ":authority", "localhost:8080");
hpackEncoder.EncodeHeader(binWriter, ":method", "GET");
hpackEncoder.EncodeHeader(binWriter, ":path", "/");
hpackEncoder.EncodeHeader(binWriter, ":scheme", "http");
// send the data (binWriter) to the server!
// wait for receiving headers...
// for this example the encoded data in binWriter.
var headerBlockFragment = new byte[binWriter.BaseStream.Length];
binWriter.BaseStream.Position = 0;
binWriter.BaseStream.Read(headerBlockFragment, 0, binWriter.BaseStream.Length);
using(var binReader = new BinaryReader(new MemoryStream(headerBlockFragment))) {
hpackDecoder.Decode(binReader, headerListener);
hpackDecoder.EndHeaderBlock(); // this must be called to finalize the decoding process.
// now the decoded headers should be printed from the defined "headerListener.HeaderEmitted" above.
}
}
...
