下载二进制文件https://github.com/protocolbuffers/protobuf/releases 下拉到最下方下载系统对应的版本将解压出来bin目录下的protoc.exe拷贝到GOPATH的bin目录下。查看protoc版本protoc --version。 protoc-gen-go插件安装 protoc是针对所有语言开发的protoc-gen-go是专门针对go语言开发因为是使用go语言开发的所以直接使用go install就可以进行安装安装后在GOPATH的bin沐目录下就会有对应的二进制文件。go install google.golang.org/protobuf/cmd/protoc-gen-golatest版本验证protoc-gen-go --versiongo install google.golang.org/grpc/cmd/protoc-gen-go-grpclatest版本验证protoc-gen-go-grpc --version kratos工具安装 kratos也是go语言编写的帮助我们快速生成代码的直接go install安装即可安装完成也会在GOPATH的bin目录中生成二进制文件。安装命令go install github.com/go-kratos/kratos/cmd/kratos/v2latest版本验证kratos -v 2.验证码服务 2.1 kratos 初始化验证码服务项目 kratos new kratos-demo03PS E:\java\go_code kratos new kratos-demo03Creating service kratos-demo03, layout
