执行命令，生成控制器：

$ gf gen pb

编写逻辑，调用单词微服务：

app/word/internal/controller/words/words.go

package words  
  
import (  
    "context"  
  
    "proxima/app/word/api/pbentity"
    v1 "proxima/app/word/api/words/v1"  
    "proxima/app/word/internal/logic/words"  
    "github.com/gogf/gf/contrib/rpc/grpcx/v2"
)
  
type Controller struct {  
    v1.UnimplementedWordsServer  
}  
  
func Register(s *grpcx.GrpcServer) {  
    v1.RegisterWordsServer(s.Server, &Controller{})  
}  
  
func (*Controller) Create(ctx context.Context, req *v1.CreateReq) (res *v1.CreateRes, err error) {  
    id, err := words.Create(ctx)  
    if err != nil {  
       return nil, err  
    }  
    return &v1.CreateRes{Id: uint32(id)}, nil  
}  
  
func (*Controller) Get(ctx context.Context, req *v1.GetReq) (res *v1.GetRes, err error) {  
    data, err := words.Get(ctx)  
    if err != nil {  
       return nil, err  
    }  
    return &v1.GetRes{  
       Words: &pbentity.Words{  
          Id:                 uint32(data.Id),  
          Uid:                uint32(data.Uid),  
          Word:               data.Word,  
          Definition:         data.Definition,  
          ExampleSentence:    data.ExampleSentence,  
          ChineseTranslation: data.ChineseTranslation,  
          Pronunciation:      data.Pronunciation,  
          CreatedAt:          timestamppb.New(data.CreatedAt.Time),
