undefined: api.HelloReq about kratos

[lintanghui]

this had been mentioned at #41 . if you want to use grpc, kprotoc must be installed to generate api.pb.go. you can use kratos/tool/kprotoc/install_kprotoc.sh to install this tool

[zhaoshichen1]

yes.

or you could run directly kratos/tool/kprotoc/kprotoc.sh to install protoc and then run this command:
protoc -I. --gogofast_out=plugins=grpc:. api.proto
in this kratos-demo/api directory, thus you will get the api.pb.go file generated which could allow you build this project

  • kratos tool kprotoc
  • cd kratos-demo/cmd & go build
• windows: install protoc and gogo protobuf，then run:
  • cd kratos-demo/api
  • protoc --gogofast_out=plugins=grpc:$GOPATH/src api.proto
  • cd kratos-demo/cmd & go build
• linux: install protoc first, then run:
  • cd kratos-demo/api
  • kratos tool kprotoc
  • cd kratos-demo/cmd & go build
