Server SDK Mode

SDK Mode（invoker）provides a way to call Kitex server just like a SDK.

message is used to start a call, you should use local and remote two net.Addr to initialize message. Which indicates local and remote address (used in logging and tracing). After initialization, you can use SetRequestBytes(buf []byte) error to setup request binary. Then call Call method of invoker to start a call. After call, you can use GetResponseBytes() ([]byte, error) of message to get response binary.

import (
    ...
    "github.com/cloudwego/kitex/server/invoke"
    ...
)

func main() {
    var reqPayload, respPayload []byte
    var local, remote net.Addr
    ...
    // init local/remote
    ...
    ivk := echo.NewInvoker(new(EchoImpl))
    msg := invoke.NewMessage(local, remote)
    // setup request payload
    msg.SetRequestBytes(reqPayload)
    // start a call
    err := ivk.Call(msg)
    if err != nil {
        ...
    }
    respPayload, err = msg.GetResponseBytes()
    if err != nil {
        ...
    }
}
