Rest API
1. 启动 REST 服务
通过以下方式可以启动 RestAPI 服务：
kcl server
然后可以通过 POST 协议请求服务：
curl -X POST http://127.0.0.1:2021/api:protorpc/BuiltinService.Ping --data '{}'
期望输出为
{
"error": "",
"result": {}
}
其中 POST 请求和返回的 JSON 数据和 Protobuf 定义的结构保持一致。
2. BuiltinService 服务
其中 /api:protorpc/BuiltinService.Ping 路径表示 BuiltinService 服务的 Ping 方法。
完整的 BuiltinService 由 Protobuf 定义：

//
// This file defines the request parameters and return structure of the KCL RPC server.
