Casdoor is an open-source Identity and Access Management (IAM) / Single-Sign-On (SSO) platform with web UI supporting OAuth 2.0, OIDC, SAML and CAS. It provides a comprehensive solution for user authentication, authorization, and management across multiple applications and services.

Pros

• Supports multiple authentication protocols (OAuth 2.0, OIDC, SAML, CAS)
• Offers a user-friendly web interface for easy management
• Integrates with various third-party identity providers (Google, GitHub, Facebook, etc.)
• Highly customizable and extensible

Cons

• Relatively new project, may have fewer community resources compared to more established IAM solutions
• Documentation could be more comprehensive for advanced use cases
• May require additional configuration for complex enterprise environments
• Limited built-in analytics and reporting features

Code Examples

1. Initializing Casdoor SDK in Go:

package main

import (
    "github.com/casdoor/casdoor-go-sdk/casdoorsdk"
)

func main() {
    client := casdoorsdk.NewClient("http://localhost:8000", "YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET")
}

2. Authenticating a user with username and password:

token, err := client.GetOAuthToken("password", "username", "password", "")
if err != nil {
    // Handle error
}
// Use the token for authenticated requests

3. Retrieving user information:

user, err := client.GetUser("username")
if err != nil {
    // Handle error
}
// Access user properties
fmt.Printf("User: %s, Email: %s\n", user.Name, user.Email)
