Using RPC API

Steps

Example

1. Build RPC Client

CapaRpcClient capaRpcClient = new CapaRpcClientBuilder().build();

2. Invoke request

Mono<byte[]> responseMono = capaRpcClient.invokeMethod(SERVICE_APP_ID,
        "hello",
        "hello",
        HttpExtension.POST,
        null,
        TypeRef.BYTE_ARRAY);

3. Get invocation result

byte[] response = responseMono.block();

Explanation

1. The RPC capabilities provided by CapaRpcClient require concrete implementation, as shown in the example DemoCapaHttp.
2. After implementing DemoCapaHttp, it needs to be configured in capa-component-rpc.properties, and loaded through the SPI mechanism.
