Redis Adapter

Redis Adapter is the Redis adapter for Casbin. With this library, Casbin can load policy from Redis or save policy to it.

Installation

go get github.com/casbin/redis-adapter/v3

Configuration Options

The Config struct supports the following options:

• Network (string): Network type, e.g., “tcp”, “unix” (required when not using Pool)
• Address (string): Redis server address, e.g., “127.0.0.1:6379” (required when not using Pool)
• Key (string): Redis key to store Casbin rules (default: “casbin_rules”)
• Username (string): Username for Redis authentication (optional)
• Password (string): Password for Redis authentication (optional)
• TLSConfig (*tls.Config): TLS configuration for secure connections (optional)
• Pool (*redis.Pool): Existing Redis connection pool (optional, if provided, other connection options are ignored)

Usage Examples

Basic Usage

package main

import (
	"github.com/casbin/casbin/v2"
	"github.com/casbin/redis-adapter/v3"
)

func main() {
	// Recommended approach using Config
	config := &redisadapter.Config{Network: "tcp", Address: "127.0.0.1:6379"}
	a, _ := redisadapter.NewAdapter(config)

	// With password authentication
	// config := &redisadapter.Config{Network: "tcp", Address: "127.0.0.1:6379", Password: "123"}
	// a, _ := redisadapter.NewAdapter(config)

	// With user credentials
	// config := &redisadapter.Config{Network: "tcp", Address: "127.0.0.1:6379", Username: "user", Password: "pass"}
	// a, _ := redisadapter.NewAdapter(config)

	// With TLS configuration
	// var clientTLSConfig tls.Config
	// ...
	// config := &redisadapter.Config{Network: "tcp", Address: "127.0.0.1:6379", Username: "testAccount", Password: "123456", TLSConfig: &clientTLSConfig}
	// a, _ := redisadapter.NewAdapter(config)

	e, _ := casbin.NewEnforcer("examples/rbac_model.conf", a)

	// Load the policy from DB.
	e.LoadPolicy()

	// Check the permission.
	e.Enforce("alice", "data1", "read")

	// Modify the policy.
	// e.AddPolicy(...)
	// e.RemovePolicy(...)

	// Save the policy back to DB.
	e.SavePolicy()
}

With Connection Pool

package main

import (
	"github.com/casbin/casbin/v2"
	"github.com/casbin/redis-adapter/v3"
	"github.com/gomodule/redigo/redis"
)

func main() {
	pool := &redis.Pool{Dial: func() (redis.Conn, error) { return redis.Dial("tcp", "127.0.0.1:6379") }}
	config := &redisadapter.Config{Pool: pool, Key: "casbin_rules"}
	a, _ := redisadapter.NewAdapter(config)

	e, _ := casbin.NewEnforcer("examples/rbac_model.conf", a)
	
	// Load the policy from DB.
	e.LoadPolicy()

	// Check the permission.
	e.Enforce("alice", "data1", "read")

	// Save the policy back to DB.
	e.SavePolicy()
}
