Go --- gin配置swagger

• 所有代码和命令

1. 下载swag for go

go get -u github.com/swaggo/swag/cmd/swag

2. 然后执行

swag init

你就会发现自己的项目中多出一个docs文档文件

3. 下载 gin-swagger

go get -u github.com/swaggo/gin-swagger
go get -u github.com/swaggo/files

4. 在你的代码中引入

import "github.com/swaggo/gin-swagger" // gin-swagger middleware
import "github.com/swaggo/files" // swagger embed files

测试：
测试方法：

// PingExample godoc
// @Summary ping example
// @Schemes
// @Description do ping
// @Tags example
// @Accept json
// @Produce json
// @Success 200 {string} Helloworld
// @Router /example/helloworld [get]
func Helloworld(g *gin.Context)  {
	g.JSON(http.StatusOK,"helloworld")
}

当这个方法存在时，再次使用swag init将会更新文档中的信息
如果要使用这个文档就要先引用

import (
    docs "GinTest/swag/docs"
)

然后再 main.go 中配置swagger

func main()  {
	r := gin.Default()
	docs.SwaggerInfo.Title = "Swagger Example API"
	docs.SwaggerInfo.Description = "This is a sample server Petstore server."
	docs.SwaggerInfo.Version = "1.0"
	docs.SwaggerInfo.Host = "localhost:8080"
	docs.SwaggerInfo.Schemes = []string{"http", "https"}
	docs.SwaggerInfo.BasePath = "/api/v1"
	v1 := r.Group("/api/v1")
	{
		eg := v1.Group("/example")
		{
			eg.GET("/helloworld",Helloworld)
		}
	}
	r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerfiles.Handler))
	r.Run(":8080")
}

此时的项目结构为

启动项目，然后访问

http://localhost:8080/swagger/index.html

这时你就会看到

需要安装

go get -u github.com/swaggo/swag/cmd/swag
go get -u github.com/swaggo/gin-swagger
go get -u github.com/swaggo/files

需要在代码中导入的

import "github.com/swaggo/gin-swagger" // gin-swagger middleware
import "github.com/swaggo/files" // swagger embed files
import  docs "GinTest/swag/docs" // your docs

测试代码：

package main

import (
	docs "GinTest/swag/docs"
	"github.com/gin-gonic/gin"
	swaggerfiles "github.com/swaggo/files"
	ginSwagger "github.com/swaggo/gin-swagger"
	"net/http"
)
// @BasePath /api/v1

// PingExample godoc
// @Summary ping example
// @Schemes
// @Description do ping
// @Tags example
// @Accept json
// @Produce json
// @Success 200 {string} Helloworld
// @Router /example/helloworld [get]
func Helloworld(g *gin.Context)  {
	g.JSON(http.StatusOK,"helloworld")
}

func main()  {
	r := gin.Default()
	docs.SwaggerInfo.Title = "Swagger Example API"
	docs.SwaggerInfo.Description = "This is a sample server Petstore server."
	docs.SwaggerInfo.Version = "1.0"
	docs.SwaggerInfo.Host = "localhost:8080"
	docs.SwaggerInfo.Schemes = []string{"http", "https"}
	docs.SwaggerInfo.BasePath = "/api/v1"
	v1 := r.Group("/api/v1")
	{
		eg := v1.Group("/example")
		{
			eg.GET("/helloworld",Helloworld)
		}
	}
	r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerfiles.Handler))
	r.Run(":8080")
}
