# Casbin Access Control Framework Examples

## Project Introduction

This repository provides comprehensive usage examples of the Casbin access control framework, including basic ACL, RBAC permission model implementations, and integration examples with mainstream Go web frameworks and ORMs.

## Casbin Features

- Support for multiple access control models: ACL, RBAC, ABAC, etc.
- Flexible policy configuration: file-based or database storage
- Multi-language implementation: Go, Java, Python, Node.js, etc.
- Framework-agnostic: can be integrated with any framework
- High performance: optimized policy matching algorithms

## Quick Start

### 1. Install Dependencies

```bash
go get github.com/casbin/casbin/v2
```

### 2. Basic Usage Example

```go
// Basic ACL permission check example
package main

import (
	"fmt"
	"github.com/casbin/casbin/v2"
)

func main() {
	// Initialize enforcer
	e, err := casbin.NewEnforcer("model.pml", "policy.csv")
	if err != nil {
		fmt.Printf("Failed to initialize Casbin: %v\n", err)
		return
	}

	// Check permission
	ok, err := e.Enforce("alice", "data1", "read")
	if err != nil {
		fmt.Printf("Permission check error: %v\n", err)
	}

	if ok {
		fmt.Println("Permission granted")
	} else {
		fmt.Println("Permission denied")
	}
}
```

### 3. Run Examples

Execute basic example:
```bash
go run 1.基本使用.go
```

Execute RBAC example:
```bash
go run 2.rbac.go
```
