为什么要用dapr

    服务之间相互调用，需要写一套逻辑去维护
    1 服务发现、熔断、限流等
    2 dapr 实现了aws、redis、aliyun等服务，无需专注每个平台等开发

    dapr可以实现服务发现、熔断、限流等，可以专注于逻辑等开发

    服务器：2

    1. 编译生成main
    2. go build -o main main.go
    4. 把服务加入dapr中
    5. dapr run --app-id Base --app-protocol grpc --app-port 5001 ./main &
    7. 开启远程调用服务
    8. dapr invoke --app-id Base --method test
    12. go build main.go && dapr run --app-id base-grpc --app-port 8080 --app-protocol grpc -- ./main -e fat
    15. go build main.go && dapr run --app-id base-http --app-port 8199 -- ./main -e dev
