swag

🌍 English ∙ 简体中文

Swag converts Go annotations to Swagger Documentation 2.0. We've created a variety of plugins for popular Go web frameworks. This allows you to quickly integrate with an existing Go project (using Swagger UI).

• About the Project

Getting started

1. Add comments to your API source code, See Declarative Comments Format.

2. Download swag by using:

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

# 1.16 or newer
$ go install github.com/swaggo/swag/cmd/swag@latest

To build from source you need Go (1.15 or newer).

Or download a pre-compiled binary from the release page.

3. Run swag init in the project's root folder which contains the main.go file. This will parse your comments and generate the required files (docs folder and docs/docs.go).

$ swag init

Make sure to import the generated docs/docs.go so that your specific configuration gets init'ed. If your General API annotations do not live in main.go, you can let swag know with -g flag.

swag init -g http/api.go

4. (optional) Use swag fmt format the SWAG comment. (Please upgrade to the latest version)

swag fmt

How to use it with Gin

Find the example source code here.

1. After using swag init to generate Swagger 2.0 docs, import the following packages:

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

2. Add General API annotations in main.go code:

// @title           Swagger Example API
// @version         1.0
// @description     This is a sample server celler server.
// @termsOfService  http://swagger.io/terms/

// @contact.name   API Support
// @contact.url    http://www.swagger.io/support
// @contact.email  [email protected]

// @license.name  Apache 2.0
// @license.url   http://www.apache.org/licenses/LICENSE-2.0.html

// @host      localhost:8080
// @BasePath  /api/v1

// @securityDefinitions.basic  BasicAuth
func main() {
	r := gin.Default()

	c := controller.NewController()

	v1 := r.Group("/api/v1")
	{
		accounts := v1.Group("/accounts")
		{
			accounts.GET(":id", c.ShowAccount)
			accounts.GET("", c.ListAccounts)
			accounts.POST("", c.AddAccount)
			accounts.DELETE(":id", c.DeleteAccount)
			accounts.PATCH(":id", c.UpdateAccount)
			accounts.POST(":id/images", c.UploadAccountImage)
		}
    //...
	}
	r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerFiles.Handler))
	r.Run(":8080")
}
//...

Additionally some general API info can be set dynamically. The generated code package docs exports SwaggerInfo variable which we can use to set the title, description, version, host and base path programmatically. Example using Gin:

package main

import (
	"github.com/gin-gonic/gin"
	"github.com/swaggo/files"
	"github.com/swaggo/gin-swagger"
	
	"./docs" // docs is generated by Swag CLI, you have to import it.
)

// @contact.name   API Support
// @contact.url    http://www.swagger.io/support
// @contact.email  [email protected]

// @license.name  Apache 2.0
// @license.url   http://www.apache.org/licenses/LICENSE-2.0.html
func main() {

	// programmatically set swagger info
	docs.SwaggerInfo.Title = "Swagger Example API"
	docs.SwaggerInfo.Description = "This is a sample server Petstore server."
	docs.SwaggerInfo.Version = "1.0"
	docs.SwaggerInfo.Host = "petstore.swagger.io"
	docs.SwaggerInfo.BasePath = "/v2"
	docs.SwaggerInfo.Schemes = []string{"http", "https"}
		
	r := gin.New()

	// use ginSwagger middleware to serve the API docs
	r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerFiles.Handler))

	r.Run()
}

3. Add API Operation annotations in controller code

package controller

import (
    "fmt"
    "net/http"
    "strconv"

    "github.com/gin-gonic/gin"
    "github.com/swaggo/swag/example/celler/httputil"
    "github.com/swaggo/swag/example/celler/model"
)

// ShowAccount godoc
// @Summary      Show an account
// @Description  get string by ID
// @Tags         accounts
// @Accept       json
// @Produce      json
// @Param        id   path      int  true  "Account ID"
// @Success      200  {object}  model.Account
// @Failure      400  {object}  httputil.HTTPError
// @Failure      404  {object}  httputil.HTTPError
// @Failure      500  {object}  httputil.HTTPError
// @Router       /accounts/{id} [get]
func (c *Controller) ShowAccount(ctx *gin.Context) {
  id := ctx.Param("id")
  aid, err := strconv.Atoi(id)
  if err != nil {
    httputil.NewError(ctx, http.StatusBadRequest, err)
    return
  }
  account, err := model.AccountOne(aid)
  if err != nil {
    httputil.NewError(ctx, http.StatusNotFound, err)
    return
  }
  ctx.JSON(http.StatusOK, account)
}

// ListAccounts godoc
// @Summary      List accounts
// @Description  get accounts
// @Tags         accounts
// @Accept       json
// @Produce      json
// @Param        q    query     string  false  "name search by q"  Format(email)
// @Success      200  {array}   model.Account
// @Failure      400  {object}  httputil.HTTPError
// @Failure      404  {object}  httputil.HTTPError
// @Failure      500  {object}  httputil.HTTPError
// @Router       /accounts [get]
func (c *Controller) ListAccounts(ctx *gin.Context) {
  q := ctx.Request.URL.Query().Get("q")
  accounts, err := model.AccountsAll(q)
  if err != nil {
    httputil.NewError(ctx, http.StatusNotFound, err)
    return
  }
  ctx.JSON(http.StatusOK, accounts)
}
//...

$ swag init

4. Run your app, and browse to http://localhost:8080/swagger/index.html. You will see Swagger 2.0 Api documents as shown below:

Using markdown descriptions

When a short string in your documentation is insufficient, or you need images, code examples and things like that you may want to use markdown descriptions. In order to use markdown descriptions use the following annotations.

annotation	description	example
title	Required. The title of the application.	// @title Swagger Example API
version	Required. Provides the version of the application API.	// @version 1.0
description.markdown	A short description of the application. Parsed from the api.md file. This is an alternative to @description	// @description.markdown No value needed, this parses the description from api.md

tag.description.markdown	Description of the tag this is an alternative to tag.description. The description will be read from a file named like tagname.md	// @tag.description.markdown

API Operation

Example celler/controller

annotation	description
description	A verbose explanation of the operation behavior.
description.markdown	A short description of the application. The description will be read from a file. E.g. @description.markdown details will load details.md

validate	string	Determines the validation for the parameter. Possible values are: required.
default	*	Declares the value of the parameter that the server will use if none is provided, for example a "count" to control the number of results per page might default to 100 if not supplied by the client in the request. (Note: "default" has no meaning for required parameters.) See https://tools.ietf.org/html/draft-fge-json-schema-validation-00#section-6.2. Unlike JSON Schema this value MUST conform to the defined type for this parameter.
maximum	number	See https://tools.ietf.org/html/draft-fge-json-schema-validation-00#section-5.1.2.

Examples

Descriptions over multiple lines

You can add descriptions spanning multiple lines in either the general api description or routes definitions like so:

// @description This is the first line
// @description This is the second line
// @description And so forth.

User defined structure with an array type

// @Success 200 {array} model.Account <-- This is a user defined struct.

package model

type Account struct {
    ID   int    `json:"id" example:"1"`
    Name string `json:"name" example:"account name"`
}

Model composition in response

// JSONResult's data field will be overridden by the specific type proto.Order
@success 200 {object} jsonresult.JSONResult{data=proto.Order} "desc"

type JSONResult struct {
    Code    int          `json:"code" `
    Message string       `json:"message"`
    Data    interface{}  `json:"data"`
}

type Order struct { //in `proto` package
    Id  uint            `json:"id"`
    Data  interface{}   `json:"data"`
}

• also support array of objects and primitive types as nested response

@success 200 {object} jsonresult.JSONResult{data=[]proto.Order} "desc"
@success 200 {object} jsonresult.JSONResult{data=string} "desc"
@success 200 {object} jsonresult.JSONResult{data=[]string} "desc"

• overriding multiple fields. field will be added if not exists

@success 200 {object} jsonresult.JSONResult{data1=string,data2=[]string,data3=proto.Order,data4=[]proto.Order} "desc"

• overriding deep-level fields

type DeepObject struct { //in `proto` package
	...
}
@success 200 {object} jsonresult.JSONResult{data1=proto.Order{data=proto.DeepObject},data2=[]proto.Order{data=[]proto.DeepObject}} "desc"

Add a headers in response

// @Success      200              {string}  string    "ok"
// @failure      400              {string}  string    "error"
// @response     default          {string}  string    "other error"
// @Header       200              {string}  Location  "/entity/1"
// @Header       200,400,default  {string}  Token     "token"
// @Header       all              {string}  Token2    "token2"

Use multiple path params

/// ...
// @Param group_id   path int true "Group ID"
// @Param account_id path int true "Account ID"
// ...
// @Router /examples/groups/{group_id}/accounts/{account_id} [get]

Add multiple paths

/// ...
// @Param group_id path int true "Group ID"
// @Param user_id  path int true "User ID"
// ...
// @Router /examples/groups/{group_id}/user/{user_id}/address [put]
// @Router /examples/user/{user_id}/address [put]

Example value of struct

type Account struct {
    ID   int    `json:"id" example:"1"`
    Name string `json:"name" example:"account name"`
    PhotoUrls []string `json:"photo_urls" example:"http://test/image/1.jpg,http://test/image/2.jpg"`
}

SchemaExample of body

// @Param email body string true "message/rfc822" SchemaExample(Subject: Testmail\r\n\r\nBody Message\r\n)

Description of struct

// Account model info
// @Description User account information
// @Description with user id and username
type Account struct {
	// ID this is userid
	ID   int    `json:"id"`
	Name string `json:"name"` // This is Name
}

#708 The parser handles only struct comments starting with @Description attribute. But it writes all struct field comments as is.

So, generated swagger doc as follows:

"Account": {
  "type":"object",
  "description": "User account information with user id and username"
  "properties": {
    "id": {
      "type": "integer",
      "description": "ID this is userid"
    },
    "name": {
      "type":"string",
      "description": "This is Name"
    }
  }
}

Use swaggertype tag to supported custom type

#201

type TimestampTime struct {
    time.Time
}

///implement encoding.JSON.Marshaler interface
func (t *TimestampTime) MarshalJSON() ([]byte, error) {
    bin := make([]byte, 16)
    bin = strconv.AppendInt(bin[:0], t.Time.Unix(), 10)
    return bin, nil
}

func (t *TimestampTime) UnmarshalJSON(bin []byte) error {
    v, err := strconv.ParseInt(string(bin), 10, 64)
    if err != nil {
        return err
    }
    t.Time = time.Unix(v, 0)
    return nil
}
///

type Account struct {
    // Override primitive type by simply specifying it via `swaggertype` tag
    ID     sql.NullInt64 `json:"id" swaggertype:"integer"`

    // Override struct type to a primitive type 'integer' by specifying it via `swaggertype` tag
    RegisterTime TimestampTime `json:"register_time" swaggertype:"primitive,integer"`

    // Array types can be overridden using "array,<prim_type>" format
    Coeffs []big.Float `json:"coeffs" swaggertype:"array,number"`
}

#379

type CerticateKeyPair struct {
	Crt []byte `json:"crt" swaggertype:"string" format:"base64" example:"U3dhZ2dlciByb2Nrcw=="`
	Key []byte `json:"key" swaggertype:"string" format:"base64" example:"U3dhZ2dlciByb2Nrcw=="`
}

generated swagger doc as follows:

"api.MyBinding": {
  "type":"object",
  "properties":{
    "crt":{
      "type":"string",
      "format":"base64",
      "example":"U3dhZ2dlciByb2Nrcw=="
    },
    "key":{
      "type":"string",
      "format":"base64",
      "example":"U3dhZ2dlciByb2Nrcw=="
    }
  }
}

Use global overrides to support a custom type

If you are using generated files, the swaggertype or swaggerignore tags may not be possible.

By passing a mapping to swag with --overridesFile you can tell swag to use one type in place of another wherever it appears. By default, if a .swaggo file is present in the current directory it will be used.

Go code:

type MyStruct struct {
  ID     sql.NullInt64 `json:"id"`
  Name   sql.NullString `json:"name"`
}

.swaggo:

// Replace all NullInt64 with int
replace database/sql.NullInt64 int

// Don't include any fields of type database/sql.NullString in the swagger docs
skip    database/sql.NullString

Possible directives are comments (beginning with //), replace path/to/a.type path/to/b.type, and skip path/to/a.type.

(Note that the full paths to any named types must be provided to prevent problems when multiple packages define a type with the same name)

Rendered:

"types.MyStruct": {
  "id": "integer"
}

Use swaggerignore tag to exclude a field

type Account struct {
    ID   string    `json:"id"`
    Name string     `json:"name"`
    Ignored int     `swaggerignore:"true"`
}

Add extension info to struct field

type Account struct {
    ID   string    `json:"id"   extensions:"x-nullable,x-abc=def,!x-omitempty"` // extensions fields must start with "x-"
}

generate swagger doc as follows:

"Account": {
    "type": "object",
    "properties": {
        "id": {
            "type": "string",
            "x-nullable": true,
            "x-abc": "def",
            "x-omitempty": false
        }
    }
}

Rename model to display

type Resp struct {
	Code int
}//@name Response

How to use security annotations

General API info.

// @securityDefinitions.basic BasicAuth

// @securitydefinitions.oauth2.application OAuth2Application
// @tokenUrl https://example.com/oauth/token
// @scope.write Grants write access
// @scope.admin Grants read and write access to administrative information

Each API operation.

// @Security ApiKeyAuth

Make it AND condition

// @Security ApiKeyAuth
// @Security OAuth2Application[write, admin]

Make it OR condition

// @Security ApiKeyAuth || firebase
// @Security OAuth2Application[write, admin] || APIKeyAuth

Add a description for enum items

type Example struct {
	// Sort order:
	// * asc - Ascending, from A to Z.
	// * desc - Descending, from Z to A.
	Order string `enums:"asc,desc"`
}

Generate only specific docs file types

By default swag command generates Swagger specification in three different files/file types:

• docs.go
• swagger.json
• swagger.yaml

If you would like to limit a set of file types which should be generated you can use --outputTypes (short -ot) flag. Default value is go,json,yaml - output types separated with comma. To limit output only to go and yaml files, you would write go,yaml. With complete command that would be swag init --outputTypes go,yaml.
