IceRpc.RequestContext 0.4.0

RequestContext interceptor and middleware for IceRPC

IceRpc.RequestContext provides an IceRPC interceptor that encodes request context features into request context fields. It also provides the corresponding middleware that decodes request context fields into request context features.

Sample code

// Client application

using IceRpc;

await using var connection = new ClientConnection(new Uri("icerpc://localhost"));

// Add the request context interceptor to the invocation pipeline.
Pipeline pipeline = new Pipeline()
    .UseRequestContext()
    .Into(connection);

// Server application

using IceRpc;

// Add the request context middleware to the dispatch pipeline.
Router router = new Router()
    .UseRequestContext()
    .Map<...>(...);

await using var server = new Server(router);
server.Listen();

Sample code with DI

// Client application

using IceRpc;
using IceRpc.Extensions.DependencyInjection;

var hostBuilder = Host.CreateDefaultBuilder(args);

hostBuilder.ConfigureServices(services =>
    services
        .AddIceRpcClientConnection(new Uri("icerpc://localhost"))
        .AddIceRpcInvoker(builder =>
            builder
                // Add the request context interceptor to the invocation pipeline.
               .UseRequestContext()
               .Into<ClientConnection>()));

using var host = hostBuilder.Build();
host.Run();

// Server application

using IceRpc;
using IceRpc.Extensions.DependencyInjection;

var hostBuilder = Host.CreateDefaultBuilder(args);

hostBuilder.ConfigureServices(services =>
    services
        .AddIceRpcServer(builder =>
            builder
                // Add the request context middleware to the dispatch pipeline.
                .UseRequestContext()
                .Map<...>()));

using var host = hostBuilder.Build();
host.Run();

Ice interop

The ice protocol can send and receive request context fields. They correspond to request contexts in Ice.
