一、安装swagger
mac : brew install go-swagger
源码方式 : dir=$(mktemp -d)
git clone https://github.com/go-swagger/go-swagger $dir
cd $dir
go install ./cmd/swagger
二、使用
1、从 swagger-ui库下载dist文件夹到自己的项目中，并更名为swagger。把swagger中的index.html的url改成./swagger.json
对一个方法添加注释 示例如下
// swagger:operation POST /machine/{type} machine createmachine
// ---
// summary: List the repositories owned by the given author.
// description: If author length is between 6 and 8, Error Not Found (404) will be returned.
// parameters:
// - name: author
// in: path
// description: username of author
// type: string
// required: true
func createMachine() string {
return ""
}
2、在项目根目录下执行 swagger generate spec -o ./swagger/swagger.json,会在swagger目录下生成一个swagger.json文件。示例：
{
"swagger": "2.0",
"paths": {
"/machine/{type}": {
"post": {
"description": "If author length is between 6 and 8, Error Not Found (404) will be returned.",
"tags": [
"machine"
],
"summary": "Create a machine.",
"operationId": "createmachine",
"parameters": [
{
"type": "string",
"description": "username of author",
"name": "author",
"in": "path",
"required": true
}
]
}
}
}
}
3、将生成的swagger.json作为一个fileServer路由加入到server中
func main() {
fs := http.FileServer(http.Dir("swagger"))
http.Handle("/swagger/", http.StripPrefix("/swagger/", fs))
http.ListenAndServe(":8000", nil)
}
4 、访问对应的路径，结果如下图：
api
