Thrifty Project

Thrifty.Net is a port of Swift（from facebook） for .Net , an attribute-based library for creating Thrift serializable types and services.

you can write C# attributed object instead of IDL file and IDL generation cli.

Thrifty = Thrift + Netty

Serialization

Thrifty Codec convert POCO to and from Thrift. Thrifty support property、method、construction attributed. for example：

    [ThriftStruct]
    public class LogEntry
    {

        [ThriftConstructor]
        public LogEntry([ThriftField(1)]String category, [ThriftField(2)]String message)
        {
            this.Category = category;
            this.Message = message;
        }

        [ThriftField(1)]
        public String Category { get; }

        [ThriftField(2)]
        public String Message { get; }
    }

Service

Thrifty Service attribute services to be exported with Thrift. For example:

    [ThriftService("scribe")]
    public interface IScribe
    {
        [ThriftMethod("getMessages")]
        List<LogEntry> GetMessages();

        [ThriftMethod]
        ResultCode Log(List<LogEntry> messages);
    }

    public class Scribe : IScribe
    {
        public List<LogEntry> GetMessages()
        {
            return new List<LogEntry>
            {
                new LogEntry { Category = "c1", Message = Guid.NewGuid().ToString() },
                new LogEntry { Category = "c2", Message = Guid.NewGuid().ToString() },
                new LogEntry { Category = "c3", Message = Guid.NewGuid().ToString() }
            };
        }

        public ResultCode Log(List<LogEntry> messages)
        {
            return ResultCode.TRY_LATER;
        }
    }

Start Server

 var factory = new LoggerFactory();
            factory.AddConsole(LogLevel.Debug);
            var serverConfig = new ThriftyServerOptions
            {
                QueueTimeout = TimeSpan.FromMinutes(1),
                TaskExpirationTimeout = TimeSpan.FromMinutes(1),
                ConnectionLimit = 10000
            };


            var bootStrap = new ThriftyBootstrap(new object[] { new Scribe() },
                serverConfig, new InstanceDescription("Sample", "EurekaInstance1", "127.0.0.1"), factory);

            bootStrap
                .SslConfig(new SslConfig
                {
                    CertFile = "server.pfx",
                    CertPassword = "abc@123",
                    CertFileProvider = new EmbeddedFileProvider(typeof(Program).GetTypeInfo().Assembly)
                })
               .AddService(typeof(IScribe), version: "1.0.0")
               //true to register into eureka , disable eureka , set to false
               .EurekaConfig(true, 
                             new EurekaClientConfig { EurekaServerServiceUrls = "http://192.168.0.10:8761/eureka" })
               // bind any
               .Bind(IPAddress.Any.ToString(), 3366)
               .StartAsync();

Use Client

var factory = new LoggerFactory();
using (var client = new ThriftyClient(new ThriftyClientOptions
{
    LoggerFactory = factory,
    ConnectionPoolEnabled = true, // default is true
    EurekaEnabled = true, //default is true
    Eureka = new ThriftyClientEurekaConfig { EurekaServerServiceUrls = "http://192.168.0.10:8761/eureka" } //optional
}))
{
    /** *************if without eureka:*****************
     * 
        var service = client.Create<Thrifty.IScribe>("127.0.0.1:3366",
        new ClientSslConfig
        {
            CertFile = "ca.crt",
            FileProvider = new EmbeddedFileProvider(typeof(ClientProgram).GetTypeInfo().Assembly)
        });
     */
    var service = client.Create<Thrifty.IScribe>("1.0.0", "EurekaInstance1",
        new ClientSslConfig
        {
            CertFile = "ca.crt",
            FileProvider = new EmbeddedFileProvider(typeof(ClientProgram).GetTypeInfo().Assembly)
        });
    var logs = service.GetMessages();
    ...
}
