为什么proto的python代码生成器不能生成类?

我目前正在尝试从proto文件生成python代码。
我的proto文件看起来像这样:

syntax = "proto3";

package display;

message Hello {
  uint32 version = 1;
  uint32 value = 2;
  int32 id = 3;
}

字符串
我使用这个protoc命令来生成python代码:

protoc -I="." --python_out="." test.proto


下面是生成的python文件:

# -*- coding: utf-8 -*-
# Generated by the protocol buffer compiler.  DO NOT EDIT!
# source: test.proto
"""Generated protocol buffer code."""
from google.protobuf.internal import builder as _builder
from google.protobuf import descriptor as _descriptor
from google.protobuf import descriptor_pool as _descriptor_pool
from google.protobuf import symbol_database as _symbol_database
# @@protoc_insertion_point(imports)

_sym_db = _symbol_database.Default()



DESCRIPTOR = _descriptor_pool.Default().AddSerializedFile(b'\n\ntest.proto\x12\x07\x64isplay\"3\n\x05Hello\x12\x0f\n\x07version\x18\x01 \x01(\r\x12\r\n\x05value\x18\x02 \x01(\r\x12\n\n\x02id\x18\x03 \x01(\x05\x62\x06proto3')

_builder.BuildMessageAndEnumDescriptors(DESCRIPTOR, globals())
_builder.BuildTopDescriptorsAndMessages(DESCRIPTOR, 'test_pb2', globals())
if _descriptor._USE_C_DESCRIPTORS == False:

  DESCRIPTOR._options = None
  _HELLO._serialized_start=23
  _HELLO._serialized_end=74
# @@protoc_insertion_point(module_scope)


它看起来一点也不像这个页面上的Google文档:https://developers.google.com/protocol-buffers/docs/pythontutorial
你知道为什么没有生成元类吗?
我使用Python 3.9和最新版本的protobuf包和最新版本的protoc。

x8goxv8g

x8goxv8g1#

添加--grpc_python_out="."到这protoc命令.这将产生一个额外的脚本与这需要的classes
