Generate Swagger files

This guide explains how to regenerate the Swagger files of the Casdoor API after you add or change an API handler.

Learning outcomes​

  • Annotate an API handler so that it appears in the Swagger files.
  • Build the modified bee tool.
  • Generate the Swagger files for all APIs or for selected ones.

What you need​

About Swagger in Casdoor​

Casdoor is built on the Beego framework, whose bee command-line tool generates Swagger files from comments in the code. The standard bee doesn't group APIs. Casdoor uses a modified bee that reads an additional @Tag annotation and groups the APIs with the same tag.

nota

Casdoor serves the Swagger UI at /swagger only when runmode = dev is set in conf/app.conf. It isn't available in production mode.

Annotate the API handler​

Write the comments in the standard format of bee, and add @Tag:

// @Title Login
// @Tag Login API
// @Description login
// @Param   oAuthParams     query    string  true        "oAuth parameters"
// @Param   body    body   RequestForm  true        "Login information"
// @Success 200 {object} controllers.api_controller.Response The Response object
// @router /login [post]
func (c *ApiController) Login() {

APIs with the same @Tag appear in the same group.

Generate the files​

  1. Clone the modified bee.

  2. Build it in the root of its repository:

    go build -o mybee .

  3. Copy mybee to the root of the Casdoor repository.

  4. In the root of the Casdoor repository, generate the files:

    mybee generate docs

To generate the files for selected tags or APIs only, name them. Separate several names with a comma.

mybee generate docs --tags "Adapter API"
mybee generate docs --tags "Adapter API,Login API"
mybee generate docs --apis "add-adapter"
mybee generate docs --apis "add-adapter,delete-adapter"

The generated files are in the swagger directory of the Casdoor repository.
