Adapters
Dans Casbin, le stockage des politiques est implémenté sous forme d'adaptateur (alias middleware pour Casbin). Un utilisateur de Casbin peut utiliser un adaptateur pour charger des règles de politique à partir d'un stockage (alias LoadPolicy()
), ou pour enregistrer des règles de politique dans celui-ci (alias SavePolicy()
). للحفاظ على الوزن الخفيف، لا نضع رمز المحول في المكتبة الرئيسية.

- إذا تم استدعاء
casbin.NewEnforcer()
بمحول صريح أو ضمني، سيتم تحميل السياسة تلقائيًا. - يمكنك استدعاء
e.LoadPolicy()
لإعادة تحميل قواعد السياسة من التخزين. - Si l'adaptateur ne prend pas en charge la fonctionnalité
Auto-Save
, les règles de politique ne peuvent pas être enregistrées automatiquement dans le stockage lorsque vous ajoutez ou supprimez des politiques. Vous devez appelerSavePolicy()
manuellement pour enregistrer toutes les règles de politique.
أمثلة
Voici plusieurs exemples :
محول الملف (مدمج)
Ci-dessous est illustré comment initialiser un enforcer à partir de l'adaptateur de fichier intégré :
- Go
- PHP
- Rust
import "github.com/casbin/casbin"
e := casbin.NewEnforcer("examples/basic_model.conf", "examples/basic_policy.csv")
use Casbin\Enforcer;
$e = new Enforcer('examples/basic_model.conf', 'examples/basic_policy.csv');
use casbin::prelude::*;
let mut e = Enforcer::new("examples/basic_model.conf", "examples/basic_policy.csv").await?;
C'est la même chose que :
- Go
- PHP
- Rust
import (
"github.com/casbin/casbin"
"github.com/casbin/casbin/file-adapter"
)
a := fileadapter.NewAdapter("examples/basic_policy.csv")
e := casbin.NewEnforcer("examples/basic_model.conf", a)
use Casbin\Enforcer;
use Casbin\Persist\Adapters\FileAdapter;
$a = new FileAdapter('examples/basic_policy.csv');
$e = new Enforcer('examples/basic_model.conf', $a);
use casbin::prelude::*;
let a = FileAdapter::new("examples/basic_policy.csv");
let e = Enforcer::new("examples/basic_model.conf", a).await?;
محول MySQL
Ci-dessous est illustré comment initialiser un enforcer à partir de la base de données MySQL. Il se connecte à une base de données MySQL sur 127.0.0.1:3306 avec l'utilisateur root et un mot de passe vide.
- Go
- Rust
- PHP
import (
"github.com/casbin/casbin"
"github.com/casbin/mysql-adapter"
)
a := mysqladapter.NewAdapter("mysql", "root:@tcp(127.0.0.1:3306)/")
e := casbin.NewEnforcer("examples/basic_model.conf", a)
// https://github.com/casbin-rs/diesel-adapter
// make sure you activate feature `mysql`
use casbin::prelude::*;
use diesel_adapter::{ConnOptions, DieselAdapter};
let mut conn_opts = ConnOptions::default();
conn_opts
.set_hostname("127.0.0.1")
.set_port(3306)
.set_host("127.0.0.1:3306") // overwrite hostname, port config
.set_database("casbin")
.set_auth("casbin_rs", "casbin_rs");
let a = DieselAdapter::new(conn_opts)?;
let mut e = Enforcer::new("examples/basic_model.conf", a).await?;
// https://github.com/php-casbin/dbal-adapter
use Casbin\Enforcer;
use CasbinAdapter\DBAL\Adapter as DatabaseAdapter;
$config = [
// Either 'driver' with one of the following values:
// pdo_mysql,pdo_sqlite,pdo_pgsql,pdo_oci (unstable),pdo_sqlsrv,pdo_sqlsrv,
// mysqli,sqlanywhere,sqlsrv,ibm_db2 (unstable),drizzle_pdo_mysql
'driver' => 'pdo_mysql',
'host' => '127.0.0.1',
'dbname' => 'test',
'user' => 'root',
'password' => '',
'port' => '3306',
];
$a = DatabaseAdapter::newAdapter($config);
$e = new Enforcer('examples/basic_model.conf', $a);
Utilisez votre propre adaptateur de stockage.
يمكنك استخدام محولك الخاص كما يلي:
import (
"github.com/casbin/casbin"
"github.com/your-username/your-repo"
)
a := yourpackage.NewAdapter(params)
e := casbin.NewEnforcer("examples/basic_model.conf", a)
Migrer/Convertir entre différents adaptateurs.
Si vous souhaitez convertir l'adaptateur de A
à B
, vous pouvez procéder comme suit :
- Charger la politique de A en mémoire.
e, _ := NewEnforcer(m, A)
أو
e.SetAdapter(A)
e.LoadPolicy()
- Convertir votre adaptateur de A à B.
e.SetAdapter(B)
- Sauvegarder la politique de la mémoire vers B.
e.SavePolicy()
Charger/Sauvegarder à l'exécution.
Vous pouvez également souhaiter recharger le modèle, recharger la politique ou enregistrer la politique après l'initialisation :
// Reload the model from the model CONF file.
e.LoadModel()
// Reload the policy from file/database.
e.LoadPolicy()
// Save the current policy (usually after changed with Casbin API) back to file/database.
e.SavePolicy()
حفظ تلقائي
Il existe une fonctionnalité appelée Auto-Save
pour les adaptateurs. Lorsqu'un adaptateur prend en charge Auto-Save
, cela signifie qu'il peut prendre en charge l'ajout d'une seule règle de politique dans le stockage, ou la suppression d'une seule règle de politique du stockage. Ceci est différent de SavePolicy()
, car ce dernier supprimera toutes les règles de politique dans le stockage et enregistrera toutes les règles de politique de l'exécuteur Casbin dans le stockage. Ainsi, cela peut poser des problèmes de performance lorsque le nombre de règles de politique est important.
Lorsque l'adaptateur prend en charge Auto-Save
, vous pouvez activer cette option via la fonction Enforcer.EnableAutoSave()
. L'option est activée par défaut (si l'adaptateur la prend en charge).
- La fonctionnalité
Auto-Save
est facultative. Un adaptateur peut choisir de l'implémenter ou non. Auto-Save
ne fonctionne que pour un enforcer Casbin lorsque l'adaptateur utilisé par l'enforcer le prend en charge.- Consultez la colonne
Auto-Save
dans la liste des adaptateurs ci-dessus pour voir siAuto-Save
est pris en charge par un adaptateur.
Voici un exemple sur la façon d'utiliser Auto-Save
:
import (
"github.com/casbin/casbin"
"github.com/casbin/xorm-adapter"
_ "github.com/go-sql-driver/mysql"
)
// By default, the AutoSave option is enabled for an enforcer.
a := xormadapter.NewAdapter("mysql", "mysql_username:mysql_password@tcp(127.0.0.1:3306)/")
e := casbin.NewEnforcer("examples/basic_model.conf", a)
// Disable the AutoSave option.
e.EnableAutoSave(false)
// Because AutoSave is disabled, the policy change only affects the policy in Casbin enforcer,
// it doesn't affect the policy in the storage.
e.AddPolicy(...)
e.RemovePolicy(...)
// Enable the AutoSave option.
e.EnableAutoSave(true)
// Because AutoSave is enabled, the policy change not only affects the policy in Casbin enforcer,
// but also affects the policy in the storage.
e.AddPolicy(...)
e.RemovePolicy(...)

Comment écrire un adaptateur
Tous les adaptateurs doivent implémenter l'interface Adapter en fournissant au moins deux méthodes obligatoires : LoadPolicy(model model.Model) error
et SavePolicy(model model.Model) error
.
Les trois autres fonctions sont facultatives. Elles doivent être implémentées si l'adaptateur prend en charge la fonctionnalité Auto-Save
.
Méthode | Type | Description |
---|---|---|
ChargerPolitique() | obligatoire | Charger toutes les règles de politique à partir du stockage |
SauvegarderPolitique() | obligatoire | Sauvegarder toutes les règles de politique dans le stockage |
AjouterPolitique() | optionnel | Ajouter une règle de politique au stockage |
RemovePolicy() | optionnel | إزالة قاعدة سياسة من التخزين |
إزالةالسياسةالمصفاة() | اختياري | إزالة قواعد السياسة التي تطابق الفلتر من التخزين |
Si un adaptateur ne prend pas en charge Sauvegarde automatique
, il doit fournir une implémentation vide pour les trois fonctions optionnelles. إليك مثال لـ Golang:
// AddPolicy adds a policy rule to the storage.
func (a *Adapter) AddPolicy(sec string, ptype string, rule []string) error {
return errors.New("not implemented")
}
// RemovePolicy removes a policy rule from the storage.
func (a *Adapter) RemovePolicy(sec string, ptype string, rule []string) error {
return errors.New("not implemented")
}
// RemoveFilteredPolicy removes policy rules that match the filter from the storage.
func (a *Adapter) RemoveFilteredPolicy(sec string, ptype string, fieldIndex int, fieldValues ...string) error {
return errors.New("not implemented")
}
Le validateur Casbin ignorera l'erreur non implémenté
lors de l'appel de ces trois fonctions optionnelles.
Il y a des détails sur la façon d'écrire un adaptateur.
- بنية البيانات. L'adaptateur doit prendre en charge la lecture d'au moins six colonnes.
- اسم قاعدة البيانات. Le nom de la base de données par défaut doit être
casbin
. - اسم الجدول. Le nom de la table par défaut doit être
casbin_rule
. - عمود Ptype. Le nom de cette colonne doit être
ptype
au lieu dep_type
ouPtype
. - La définition de la table doit être
(id int clé primaire, ptype varchar, v0 varchar, v1 varchar, v2 varchar, v3 varchar, v4 varchar, v5 varchar)
. - L'index de clé unique doit être construit sur les colonnes
ptype,v0,v1,v2,v3,v4,v5
. LoadFilteredPolicy
nécessite unfilter
en paramètre. يجب أن يكون الفلتر شيئًا مثل هذا.
{
"p":[ [ "alice" ], [ "bob" ] ],
"g":[ [ "", "book_group" ], [ "", "pen_group" ] ],
"g2":[ [ "alice" ] ]
}
Qui est responsable de créer la base de données (DB) ?
وفقًا للاتفاقية، يجب أن يكون المحول قادرًا على إنشاء قاعدة بيانات تسمى casbin
تلقائيًا إذا لم تكن موجودة واستخدامها لتخزين السياسة. Veuillez utiliser l'adaptateur Xorm comme implémentation de référence : https://github.com/casbin/xorm-adapter
Adaptateur de Contexte
ContextAdapter fournit une interface contextuelle pour les adaptateurs Casbin.
Grâce au contexte, vous pouvez implémenter des fonctionnalités telles que le contrôle du délai d'attente pour l'API de l'Adaptateur.
مثال
gormadapter prend en charge l'adaptateur avec contexte, ci-dessous un exemple de contrôle du délai d'attente implémenté à l'aide du contexte.
ca, _ := NewContextAdapter("mysql", "root:@tcp(127.0.0.1:3306)/", "casbin")
// Limited time 300s
ctx, cancel := context.WithTimeout(context.Background(), 300*time.Microsecond)
defer cancel()
err := ca.AddPolicyCtx(ctx, "p", "p", []string{"alice", "data1", "read"})
if err != nil {
panic(err)
}
كيفية كتابة محول سياق
L'API ContextAdapter
a seulement une couche supplémentaire de traitement de contexte par rapport à l'API Adapter
ordinaire,
