我正在尝试设置一个示例Python gRPC示例，并具有以下proto文件：

syntax = "proto3";

package greet;

service Greeter{

  // unary
  rpc SayHello (HelloRequest) returns (HelloReply);

  // Server Streaming
  rpc ParrotSayHello (HelloRequest) returns (stream HelloReply);

  // Client Streaming
  rpc ChattyClientSayHello (stream HelloRequest) returns (DelayedReply);

  // Both Streaming
  rpc InteractingHello (stream HelloReequest) returns (stream HelloReply);

}

项目结构为：

格雷特
|- 原型

|- greet.protos

当我尝试使用以下命令运行协议时：

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

我得到下面的错误：

greet.proto:8:17: "HelloRequest" is not defined.
greet.proto:8:40: "HelloReply" is not defined.
greet.proto:11:23: "HelloRequest" is not defined.
greet.proto:11:53: "HelloReply" is not defined.
greet.proto:14:36: "HelloRequest" is not defined.
greet.proto:14:59: "DelayedReply" is not defined.
greet.proto:17:32: "HelloReequest" is not defined.
greet.proto:17:63: "HelloReply" is not defined.

我正在查看代码，发现了这个问题，即原型不正确或不完整。
下面的proto解决了这个问题（错误正是问题所在！！！）

syntax = "proto3";

package greet;

// The greeting service definition.
service Greeter {
    // Unary
    rpc SayHello (HelloRequest) returns (HelloReply);

    // Server Streaming
    rpc ParrotSaysHello (HelloRequest) returns (stream HelloReply);
    
    // Client Streaming
    rpc ChattyClientSaysHello (stream HelloRequest) returns (DelayedReply);

    // Both Streaming
    rpc InteractingHello (stream HelloRequest) returns (stream HelloReply);
}

// The request message containing the user's name.
message HelloRequest {
  string name = 1;
  string greeting = 2;
}

// The response message containing the greetings.
message HelloReply {
  string message = 1;
}

message DelayedReply {
    string message = 1;
    repeated HelloRequest request = 2;
}
