Adapters
Dalam Casbin, penyimpanan polisi dilaksanakan sebagai pengaya (juga dikenali sebagai perantaraan untuk Casbin). Pengguna Casbin boleh menggunakan pengaya untuk memuatkan peraturan polisi dari penyimpanan (juga dikenali sebagai LoadPolicy()
), atau menyimpan peraturan polisi ke dalamnya (juga dikenali sebagai SavePolicy()
). Untuk mengekalkan keberatannya, kami tidak meletakkan kod pengaya dalam pustaka utama.
Pengaya yang disokong
Senarai lengkap pengaya Casbin diberikan seperti di bawah. Sumbangan pihak ketiga ke atas pengaya baru dialu-alukan, sila maklumkan kepada kami dan kami akan meletakkannya dalam senarai ini:
- Go
- Java
- Node.js
- PHP
- Python
- .NET
- Rust

- Jika
casbin.NewEnforcer()
dipanggil dengan pengaya yang jelas atau tersirat, dasar akan dimuatkan secara automatik. - Anda boleh memanggil
e.LoadPolicy()
untuk memuatkan semula peraturan dasar dari storan. - Jika pengaya tidak menyokong ciri
Auto-Save
, Peraturan dasar tidak boleh disimpan semula ke storan secara automatik apabila anda menambah atau mengalih keluar dasar. Anda perlu memanggilSavePolicy()
secara manual untuk menyimpan semua peraturan dasar.
Contoh
Di sini kami menyediakan beberapa contoh:
Pengaya Fail (terbina dalam)
Di bawah menunjukkan cara untuk memulakan enforcer dari pengaya fail terbina dalam:
- 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?;
Ini adalah sama dengan:
- 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?;
Penyesuai MySQL
Di bawah menunjukkan cara memulakan enforcer dari pangkalan data MySQL. ia menyambung ke DB MySQL di 127.0.0.1:3306 dengan root dan kata laluan kosong.
- 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);
Gunakan penyesuai storan anda sendiri
Anda boleh menggunakan penyesuai anda sendiri seperti di bawah:
import (
"github.com/casbin/casbin"
"github.com/your-username/your-repo"
)
a := yourpackage.NewAdapter(params)
e := casbin.NewEnforcer("examples/basic_model.conf", a)
Migrasi/Tukar antara penyesuai yang berbeza
Jika anda ingin menukar penyesuai dari A
ke B
, anda boleh lakukan seperti ini:
1.Muatkan polisi dari A ke memori
e, _ := NewEnforcer(m, A)
atau
e.SetAdapter(A)
e.LoadPolicy()
Tukar penyesuai anda dari A ke B
e.SetAdapter(B)
Simpan polisi dari memori ke B
e.SavePolicy()
Muat/Simpan pada masa berjalan
Anda mungkin juga ingin memuat semula model, memuat semula polisi atau menyimpan polisi selepas inisialisasi:
// 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()
AutoSimpan
Terdapat satu ciri yang dipanggil "Auto-Save" untuk penyesuai. Apabila penyesuai menyokong "Auto-Save", ini bermakna ia boleh menyokong menambah satu peraturan polisi ke storan, atau mengalih keluar satu peraturan polisi dari storan. Ini berbeza dengan "SavePolicy()", kerana yang terakhir akan memadam semua peraturan polisi dalam storan dan menyimpan semua peraturan polisi dari enforcer Casbin ke storan. Jadi ia mungkin mengalami masalah prestasi apabila bilangan peraturan polisi adalah besar.
Apabila penyesuai menyokong "Auto-Save", anda boleh menukar pilihan ini melalui fungsi Enforcer.EnableAutoSave()
. Pilihan ini diaktifkan secara lalai (jika penyambung menyokongnya).
- Ciri
Auto-Save
adalah pilihan. Penyambung boleh memilih untuk melaksanakannya atau tidak. Auto-Save
hanya berfungsi untuk enforcer Casbin apabila penyambung yang digunakan oleh enforcer itu menyokongnya.- Lihat lajur
AutoSave
dalam senarai penyambung di atas untuk melihat sama adaAuto-Save
disokong oleh penyambung.
Berikut adalah contoh tentang cara menggunakan 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(...)
Untuk lebih banyak contoh, sila lihat: https://github.com/casbin/xorm-adapter/blob/master/adapter_test.go
Cara menulis penyambung
Semua penyambung harus melaksanakan antara muka Adapter dengan menyediakan sekurang-kurangnya dua kaedah wajib: LoadPolicy(model model.Model) error
dan SavePolicy(model model.Model) error
.
Tiga fungsi lain adalah pilihan. Ia harus dilaksanakan jika pengubah suai menyokong ciri Auto-Save
.
Kaedah | Jenis | Penerangan |
---|---|---|
LoadPolicy() | wajib | Muatkan semua peraturan dasar dari storan |
SavePolicy() | wajib | Simpan semua peraturan dasar ke storan |
AddPolicy() | pilihan | Tambahkan peraturan polisi ke dalam penyimpanan |
RemovePolicy() | pilihan | Buang peraturan polisi dari penyimpanan |
RemoveFilteredPolicy() | pilihan | Buang peraturan polisi yang sesuai dengan penapis dari penyimpanan |
Jika pengubah tidak menyokong Auto-Save
, ia harus memberikan pelaksanaan kosong untuk ketiga-tiga fungsi pilihan tersebut. Berikut adalah contoh untuk 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")
}
Enforcer Casbin akan mengabaikan ralat tidak dilaksanakan
apabila memanggil tiga fungsi pilihan ini.
Terdapat butiran mengenai cara menulis penyesuai.
- Struktur Data. Penyesuai harus menyokong pembacaan sekurang-kurangnya enam lajur.
- Nama Pangkalan Data. Nama pangkalan data lalai haruslah
casbin
. - Nama Jadual. Nama jadual lalai haruslah
casbin_rule
. - Lajur Ptype. Nama lajur ini harus menjadi
ptype
bukanp_type
atauPtype
. - Definisi jadual harus menjadi
(id int primary key, ptype varchar, v0 varchar, v1 varchar, v2 varchar, v3 varchar, v4 varchar, v5 varchar)
. - Indeks kunci unik harus dibina pada lajur
ptype,v0,v1,v2,v3,v4,v5
. LoadFilteredPolicy
memerlukanfilter
sebagai parameter. Penapis harus menjadi seperti ini.
{
"p":[ [ "alice" ], [ "bob" ] ],
"g":[ [ "", "book_group" ], [ "", "pen_group" ] ],
"g2":[ [ "alice" ] ]
}
Siapa yang bertanggungjawab untuk mencipta DB?
Sebagai konvensyen, pengubahsuai harus dapat mencipta pangkalan data bernama casbin
secara automatik jika ia tidak wujud dan menggunakannya untuk penyimpanan dasar. Sila gunakan pengubahsuai Xorm sebagai pelaksanaan rujukan: https://github.com/casbin/xorm-adapter
Pengubahsuai Konteks
ContextAdapter menyediakan antara muka yang sedar konteks untuk pengubahsuai Casbin.
Melalui konteks, anda boleh melaksanakan ciri-ciri seperti kawalan timeout untuk API Adapter
Contoh
gormadapter menyokong adapter dengan konteks, berikut adalah kawalan timeout yang dilaksanakan menggunakan konteks
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)
}
Cara menulis adapter konteks
ContextAdapter
API hanya mempunyai lapisan tambahan pemprosesan konteks berbanding API Adapter
biasa,
