这里我就从简了，省略了更新，删除等操作，只写了Create和Get，用作示例。

app/word/manifest/protobuf/words/v1/words.proto

syntax = "proto3";  
  
package words.v1;  
  
option go_package = "proxima/app/word/api/words/v1";  
  
import "pbentity/words.proto";  
  
service Words{  
  rpc Create(CreateReq) returns (CreateRes) {}  
  rpc Get(GetReq) returns (GetRes) {}  
}  
  
message CreateReq {  
  uint32 uid = 1; // v:required  
  string word = 2; // v:required  
  string definition = 3; // v:required  
}  
  
message CreateRes {  
  uint32 id = 1;  
}  
  
message GetReq {  
  uint32 id = 1; // v:required  
}  
  
message GetRes {  
  pbentity.Words words = 1;  
}
