protoc-gen-go-gin

根据proto生成sunmi gin controller

安装

# protoc
brew install protobuf

# protoc-gen-go (生成 {package}.pb.go)
wget 'http://qiniu.brightguo.com/sunmi/protoc-gen-go_mac13.0' -O protoc-gen-go && chmod +x protoc-gen-go && mv protoc-gen-go $(go env GOPATH)/bin

# protoc-gen-go-gin（生成{package}_http_client.pb.go {package}_http_server.pb.go {package}_json.pb.go）
go install github.com/guoming0000/protoc-gen-go-gin@latest

# protoc-gen-go-errors (生成{package}_ecode.pb.go)
go install github.com/guoming0000/protoc-gen-go-gin/protoc-gen-go-errors@latest
  
# 拷贝third_party目录(protoc-gen-go-gin和protoc-gen-validate会用到)
git clone https://github.com/guoming0000/protoc-gen-go-gin.git
cp -r protoc-gen-go-gin/third_party $(go env GOPATH)/pkg/mod/github.com/guoming0000/

使用

protoc -I. -I ./third_party --go-gin_out=./ --go_out=./  api/article.proto

protoc --go-errors_out=./ api/article_error.proto

protoc -I. -I ./third_party --openapiv2_out . --openapiv2_opt logtostderr=true --openapiv2_opt json_names_for_fields=false api/article.proto

proto demo https://github.com/guoming0000/protoc-gen-go-gin/blob/main/api/article/article.proto

生成后的文件demo https://github.com/guoming0000/protoc-gen-go-gin/blob/main/api/article/

server使用demo： https://github.com/guoming0000/protoc-gen-go-gin/blob/main/api/article/articleserver_test.go

client使用demo： https://github.com/guoming0000/protoc-gen-go-gin/blob/main/api/article/client.go

struct转proto定义方法

和chatgpt聊天，话术如下：

请把这个golang struct转换为proto形式:
type GetArticlesReq struct {
	Title string `json:"title,omitempty"`
	Page  int32  `json:"page,omitempty"`
	// 字段名使用小写下划线的风格，例如 string status_code = 1
	PageSize int32                    `json:"page_size,omitempty"`
	AuthorId int32                    `json:"author_id,omitempty"`
	Email    string                   `json:"email,omitempty"`
	Name     string                   `json:"name,omitempty"`
	Home     *GetArticlesReq_Location `json:"home,omitempty"`
}

TODO

  • 支持proto-gen-error-go
  • 支持自定义错误码
  • 支持gin形式的binding参数校验方法
