Class JSONRPCTransportConfig

java.lang.Object

org.a2aproject.sdk.client.transport.spi.ClientTransportConfig<JSONRPCTransport>

org.a2aproject.sdk.client.transport.jsonrpc.JSONRPCTransportConfig

public class JSONRPCTransportConfig
extends ClientTransportConfig<JSONRPCTransport>

Configuration for the JSON-RPC transport protocol.

This configuration class allows customization of the HTTP client used for JSON-RPC communication with A2A agents. If no HTTP client is specified, the default JDK-based implementation is used.

Basic usage:

// Use default HTTP client
JSONRPCTransportConfig config = new JSONRPCTransportConfigBuilder()
    .build();

Client client = Client.builder(agentCard)
    .withTransport(JSONRPCTransport.class, config)
    .build();

Custom HTTP client:

// Custom HTTP client with timeouts
A2AHttpClient customClient = new CustomHttpClient()
    .withConnectTimeout(Duration.ofSeconds(10))
    .withReadTimeout(Duration.ofSeconds(30));

JSONRPCTransportConfig config = new JSONRPCTransportConfigBuilder()
    .httpClient(customClient)
    .build();

With interceptors:

JSONRPCTransportConfig config = new JSONRPCTransportConfigBuilder()
    .httpClient(customClient)
    .addInterceptor(new LoggingInterceptor())
    .addInterceptor(new AuthInterceptor("Bearer token"))
    .build();
