kratos快速使用

kratos new babytree -r https://gitee.com/go-kratos/kratos-layout.git

$ cd babytree
$ go generate ./...
$ go build -o ./bin/ ./...
$ ./bin/babytree -conf ./configs

添加pb文件
kratos proto add api/helloworld/v1/student.proto


生成 proto 对应代码#
通过 make 命令生成：

make api
或者通过 kratos cli 生成：

kratos proto client api/helloworld/v1/student.proto


生成 Service 代码#
通过 proto 文件，直接生成对应的 Service 代码。使用 -t 指定生成目录：

kratos proto server api/helloworld/v1/student.proto -t internal/service
