1. Protocol Buffer Language Guide
2. Python 生成代码

1. pip install grpcio
2. pip install grpcio-tools

/Users/lishulong/PycharmProjects/grpc_etct_example

python -m grpc_tools.protoc -I . --python_out=. --grpc_python_out=. ./protos/query_example.proto

想要生成在哪个包下，就把proto放到哪个包下，不用生成文件的包路径了

1. pip install etcd3
2. docker-compose up
3. http://127.0.0.1:8010/，修改下面红框的地址用来进行etcd的服务链接
