.net 7 中使用quic示例
相濡以沫，不如相忘于江湖
之前在文章在.Net 中使用Quic通信尝鲜 中介绍过如何使用quic协议， 在.net 7中，Quic相关API已经正式可用了， 不过目前还是预览状态，基本示例如下：
服务端代码：
using System;using System.Net;using System.Net.Quic;using System.Net.Security;using System.Runtime.Versioning;using System.Security.Cryptography.X509Certificates;#pragma warning disable CA1416 namespace QuicExample{ [RequiresPreviewFeatures] class Program { static async Task Main(string[] args) { var isRunning = true; if (!QuicListener.IsSupported) { Console.WriteLine("QUIC is not supported."); return; } var serverConnectionOptions = new QuicServerConnectionOptions() { DefaultStreamErrorCode = 0x0A, DefaultCloseErrorCode = 0x0B, ServerAuthenticationOptions = new SslServerAuthenticationOptions { ApplicationProtocols = new List<SslApplicationProtocol>() { new SslApplicationProtocol("protocol-name") }, ServerCertificate = X509Certificate2.CreateFromPemFile("certiciate-file-path") } }; var listener = await QuicListener.ListenAsync(new QuicListenerOptions() { ListenEndPoint = new IPEndPoint(IPAddress.Loopback, 0), ApplicationProtocols = new List<SslApplicationProtocol>() { new SslApplicationProtocol("protocol-name") }, ConnectionOptionsCallback = (_, _, _) => ValueTask.FromResult(serverConnectionOptions) }); while (isRunning) { var connection = await listener.AcceptConnectionAsync(); var stream = await connection.AcceptInboundStreamAsync(); // Work with the incoming stream ... } await listener.DisposeAsync(); } }}
客户端代码：
using System;using System.Net;using System.Net.Quic;using System.Net.Security;using System.Runtime.Versioning;using System.Security.Cryptography.X509Certificates;#pragma warning disable CA1416 namespace QuicExample{ [RequiresPreviewFeatures] class Program { static async Task Main(string[] args) { var isRunning = true; if (!QuicListener.IsSupported) { Console.WriteLine("QUIC is not supported."); return; } var clientConnectionOptions = new QuicClientConnectionOptions() { RemoteEndPoint = listener.LocalEndPoint, DefaultStreamErrorCode = 0x0A, DefaultCloseErrorCode = 0x0B, MaxInboundUnidirectionalStreams = 10, MaxInboundBidirectionalStreams = 100, ClientAuthenticationOptions = new SslClientAuthenticationOptions() { ApplicationProtocols = new List<SslApplicationProtocol>() { new SslApplicationProtocol("protocol-name") } } }; var connection = await QuicConnection.ConnectAsync(clientConnectionOptions); var outgoingStream = await connection.OpenOutboundStreamAsync(QuicStreamType.Bidirectional); // Work with the outgoing stream ... await connection.CloseAsync(0x0C); await connection.DisposeAsync(); } }}
使用的时候需要参考前面的文章安装msquic，以及准备证书。目前还是预览阶段，相关接口功能也比较少，并且后续接口也可能会发生变化（和.net 6非公开的相比已经变化不少了）。等正式版再详细使用好了。
