Публичный API Casdoor

Casdoor frontend web UI is a SPA (Single-Page Application) developed in React. The React frontend consumes the Casdoor RESTful API exposed by the Go backend code. Этот RESTful API называется Casdoor Public API. In Another word, with HTTP calls, you can do everything just like how Casdoor web UI itself does. There's no other limitations. API может быть использован следующими способами:

  • Frontend Casdoor
  • Casdoor client SDKs (e.g., casdoor-go-sdk)
  • Любой другой код, кастомизированный со стороны приложения

How to authenticate with Casdoor Public API

1. By Access token

We can use the access token granted for an authenticated user to call Casdoor Public API as the user itself.

How to get the access token?

The application can get the access token for the Casdoor user at the end of OAuth login process (aka get the token by code and state). The permissions for the API calls will be the same as the user.

The below examples shows how to call GetOAuthToken() function in Go via casdoor-go-sdk.

func (c *ApiController) Signin() {
code := c.Input().Get("code")
state := c.Input().Get("state")

token, err := casdoorsdk.GetOAuthToken(code, state)
if err != nil {
c.ResponseError(err.Error())
return
}

claims, err := casdoorsdk.ParseJwtToken(token.AccessToken)
if err != nil {
c.ResponseError(err.Error())
return
}

if !claims.IsAdmin {
claims.Type = "chat-user"
}

err = c.addInitialChat(&claims.User)
if err != nil {
c.ResponseError(err.Error())
return
}

claims.AccessToken = token.AccessToken
c.SetSessionClaims(claims)

c.ResponseOk(claims)
}

All granted access tokens can also be accessed via the web UI by an admin user in the Tokens page. For example, visit: https://door.casdoor.com/tokens for the demo site.

How to authenticate?

  1. HTTP GET parameter, the URL format is:

    /page?access_token=<The access token>

    Demo site example: https://door.casdoor.com/api/get-global-providers?access_token=eyJhbGciOiJSUzI1NiIs

  2. HTTP Bearer token, the HTTP header format is:

    Authorization: Bearer <The access token>

2. By Client ID and Client secret

How to get the client ID and secret?

The application edit page (e.g., https://door.casdoor.com/applications/casbin/app-vue-python-example) will show the client ID and secret for an application. This authentication is useful when you want to call the API as a "machine", "application" or a "service" instead of a user. The permissions for the API calls will be the same as the application (aka the admin of the organization).

The below examples shows how to call GetOAuthToken() function in Go via casdoor-go-sdk.

How to authenticate?

  1. HTTP GET parameter, the URL format is:

    /page?clientId=<The client ID>&clientSecret=<the client secret>

    Demo site example: https://door.casdoor.com/api/get-global-providers?clientId=294b09fbc17f95daf2fe&clientSecret=dd8982f7046ccba1bbd7851d5c1ece4e52bf039d

  2. HTTP Basic Authentication, the HTTP header format is:

    Authorization: Basic <The Base64 encoding of client ID and client secret joined by a single colon ":">

If you are not familiar with the Base64 encoding, you can use a library to do that because HTTP Basic Authentication is a popular standard supported by many places.

3. By username and password

caution

This authentication method is not safe and kept here only for compatibility or demo purposes. We recommend using the previous two authentication methods instead.

What will happen?

The user credential will be exposed as GET parameters the in the request URL. Moreover, the user credential will be sniffed in plain text by the network if you are using HTTP instead of HTTPS.

We can use the username and password for a Casdoor user to call Casdoor Public API as the user itself. The username takes the format of <The user's organization name>/<The user name>. The permissions for the API calls will be the same as the user.

How to authenticate?

  1. HTTP GET parameter, the URL format is:

    /page?username=<The user's organization name>/<The user name>&password=<the user's password>"
