Management API

The primitive API that provides full support for Casbin policy management.

Filtered API

Almost all filtered api has the same parameters (fieldIndex int, fieldValues ...string). fieldIndex is the index where matching start, fieldValues denotes the values result should have. Note that empty string in fieldValues could be any word.

Example:

p, alice, book, read
p, bob, book, read
p, bob, book, write
p, alice, pen, get
p, bob, pen ,get

e.GetFilteredPolicy(1, "book") // will return: [[alice book read] [bob book read] [bob book write]]

e.GetFilteredPolicy(1, "book", "read") // will return: [[alice book read] [bob book read]]

e.GetFilteredPolicy(0, "alice", "", "read") // will return: [[alice book read]]

e.GetFilteredPolicy(0, "alice") // will return: [[alice book read] [alice pen get]]

Reference

global variable e is Enforcer instance.

Go

Node.js

PHP

Python

.NET

Rust

Java

e, err := NewEnforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")

const e = await newEnforcer('examples/rbac_model.conf', 'examples/rbac_policy.csv')

$e = new Enforcer('examples/rbac_model.conf', 'examples/rbac_policy.csv');

e = casbin.Enforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")

var e = new Enforcer("path/to/model.conf", "path/to/policy.csv");

let mut e = Enforce::new("examples/rbac_model.conf", "examples/rbac_policy.csv").await?;

Enforcer e = new Enforcer("examples/rbac_model.conf", "examples/rbac_policy.csv");

Enforce()

Enforce decides whether a "subject" can access a "object" with the operation "action", input parameters are usually: (sub, obj, act).

For example:

Go

Node.js

PHP

Python

Java

ok, err := e.Enforce(request)

const ok = await e.enforce(request);

$ok = $e->enforcer($request);

ok = e.enforcer(request)

boolean ok = e.enforce(request);

EnforceWithMatcher()

EnforceWithMatcher use a custom matcher to decides whether a "subject" can access a "object" with the operation "action", input parameters are usually: (matcher, sub, obj, act), use model matcher by default when matcher is "".

For example:

Go

PHP

Python

Java

ok, err := e.EnforceWithMatcher(matcher, request)

$ok = $e->enforceWithMatcher($matcher, $request);

ok = e.enforce_with_matcher(matcher, request)

boolean ok = e.enforceWithMatcher(matcher, request);

EnforceEx()

EnforceEx explain enforcement by informing matched rules.

For example:

Go

Node.js

PHP

Python

ok, reason, err := e.EnforceEx(request)

const ok = await e.enforceEx(request);

list($ok, $reason) = $e->enforceEx($request);

ok, reason = e.enforce_ex(request)

HasGroupingPolicy()

HasGroupingPolicy determines whether a role inheritance rule exists.

For example:

Go

Node.js

PHP

Python

.NET

Rust

Java

has := e.HasGroupingPolicy("alice", "data2_admin")

const has = await e.hasGroupingPolicy('alice', 'data2_admin')

$has = $e->hasGroupingPolicy("alice", "data2_admin");

has = e.has_grouping_policy("alice", "data2_admin")

var has = e.HasGroupingPolicy("alice", "data2_admin");

let has = e.has_grouping_policy(vec!["alice".to_owned(), "data2_admin".to_owned()]);

boolean has = e.hasGroupingPolicy("alice", "data2_admin");

HasNamedGroupingPolicy()

HasNamedGroupingPolicy determines whether a named role inheritance rule exists.

For example:

Go

Node.js

PHP

Python

.NET

Rust

Java

has := e.HasNamedGroupingPolicy("g", "alice", "data2_admin")

const has = await e.hasNamedGroupingPolicy('g', 'alice', 'data2_admin')

$has = $e->hasNamedGroupingPolicy("g", "alice", "data2_admin");

AddGroupingPolicy()

AddGroupingPolicy adds a role inheritance rule to the current policy. If the rule already exists, the function returns false and the rule will not be added. Otherwise the function returns true by adding the new rule.

For example:

Go

Node.js

PHP

Python

.NET

Rust

Java

added := e.AddGroupingPolicy("group1", "data2_admin")

const added = await e.addGroupingPolicy('group1', 'data2_admin')

let added = e.add_grouping_policy(vec!["group1".to_owned(), "data2_admin".to_owned()]).await?;

boolean added = e.addGroupingPolicy("group1", "data2_admin");

AddGroupingPolicies()

AddGroupingPolicies adds role inheritance rules to the current policy. The operation is atomic in nature. Hence, if authorization rules consists of rules which are not consistent with the current policy, the function returns false and no policy rule is added to the current policy. If all authorization the rules are consistent with the policy rules, the function returns true and each policy rule is added to the current policy.

For example:

Go

Node.js

Python

Rust

Java

rules := [][] string {
    []string {"ham", "data4_admin"},
    []string {"jack", "data5_admin"},
}

areRulesAdded := e.AddGroupingPolicies(rules)

    {"ham", "data4_admin"},
    {"jack", "data5_admin"}
};
boolean areRulesAdded = e.addGroupingPolicies(groupingRules);

AddNamedGroupingPolicy()

PHP

Python

.NET

Rust

Java

added := e.AddNamedGroupingPolicy("g", "group1", "data2_admin")

var added = e.AddNamedGroupingPolicy("g", "group1", "data2_admin");
or
var added = await e.AddNamedGroupingPolicyAsync("g", "group1", "data2_admin");

let added = e.add_named_grouping_policy("g", vec!["group1".to_owned(), "data2_admin".to_owned()]).await?;

boolean added = e.addNamedGroupingPolicy("g", "group1", "data2_admin");

AddNamedGroupingPolicies()

AddNamedGroupingPolicies adds named role inheritance rules to the current policy. The operation is atomic in nature. Hence, if authorization rules consists of rules which are not consistent with the current policy, the function returns false and no policy rule is added to the current policy.
