Spdy

A client/server implementation of the Spdy 3.1 protocol.

Installation

dotnet add package Spdy

Usage

The library can act both as a client and a server. Both are un-opiniated about what transport medium is used and accepts a INetworkClient that needs to be implemented.

Client

The following example creates a client session and a stream, sends "Hello world!" to the server, closes its endpoint and then reads any responses from the server until it closes its endpoint.

var networkClient = ...;
await using var session = SpdySession.CreateClient(networkClient);
using var stream = session.CreateStream();

FlushResult flushResult;
do
{
    flushResult = await stream.SendLastAsync(
        new ReadOnlyMemory<byte>(
            Encoding.UTF8.GetBytes("Hello world!")));
} while (!flushResult.IsCompleted);

ReadResult readResult;
do
{
    readResult = await stream.ReceiveAsync();
    Console.WriteLine(
        Encoding.UTF8.GetString(readResult.Buffer.ToArray()));
} while (!readResult.IsCompleted);

Server

The following example creates a server session which starts listening for a stream created by a client, sends "Hello world!", closes its endpoint and then reads any responses from the client until it closes its endpoint.

var networkClient = ...;
await using var session = SpdySession.CreateServer(networkClient);
using var stream = await session.ReceiveStreamAsync();

FlushResult flushResult;
do
{
    flushResult = await stream.SendLastAsync(
        new ReadOnlyMemory<byte>(
            Encoding.UTF8.GetBytes("Hello world!")));
} while (!flushResult.IsCompleted);

ReadResult readResult;
do
{
    readResult = await stream.ReceiveAsync();
    Console.WriteLine(
        Encoding.UTF8.GetString(readResult.Buffer.ToArray()));
} while (!readResult.IsCompleted);

Logging

Logging can be enabled by calling Spdy.Logging.LogFactory.TryInitializeOnce(ILogFactory logFactory) with an implementation of ILogFactory. Since this method is static it will only set the first log factory it is called with and ignore all other calls.
