5 | - https://grpc.github.io/grpc/core/md_doc_g_stands_for.html
6 | - https://grpc.io/docs/languages/python/quickstart/
7 | - https://github.com/protocolbuffers/protobuf/releases/tag/v26.0
8 | - https://protobuf.dev/getting-started/pythontutorial/
9 | - https://github.com/grpc/grpc/tree/master/examples/python
10 |
11 | ## Шаги
12 |
13 | - настроили Poetry
14 | - установили Python пакет `protobuf`
15 | - поставили protobuf на macOS командой
16 | ```shell
17 | brew install protobuf
18 | ```
19 | - компилируем протокол на Python
20 | ```shell
21 | protoc --proto_path=protos --python_out=./pb protos/hello.proto
22 | ```
23 | - компилируем протокол в Python плюс аннотации типов
24 | ```shell
25 | protoc --proto_path=protos --python_out=./pb --pyi_out=./pb protos/hello.proto
26 | ```
27 | - установили Python пакет `grpcio`
28 | - установили Python пакет `grpcio-tools`
29 | - описали сервис `Greeter`
30 | - компилируем командой
31 | ```shell
32 | python -m grpc_tools.protoc --proto_path=protos --python_out=./pb --pyi_out=./pb --grpc_python_out=./pb protos/hello.proto
33 | ```
34 | - правим импорт
35 | - реализуем сервисер
36 | - запускаем сервер
37 | - вызываем клиент
38 |
39 |
40 | Example stream:
41 | ```python
42 | # client
43 | def request_iter():
44 | for idx in range(5):
45 | yield service_pb2.HelloRequest(name=f"Stream #{idx}")
46 |
47 |
48 | stub.GreetStream(request_iter())
49 |
50 | # server
51 | for r in request_iter:
52 | print(f"Stream request {r}")
53 | yield service_pb2.HelloReply(message=f"Hello, {r.name}!")
54 | ```
