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

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

Node.js

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

PHP

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

Python

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

.NET

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

Rust

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

Java

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

ok, err := e.Enforce(request)

Node.js

const ok = await e.enforce(request);

PHP

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

Python

ok = e.enforcer(request)

Java

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

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

PHP

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

Python

ok = e.enforce_with_matcher(matcher, request)

Java

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

EnforceEx()

EnforceEx explain enforcement by informing matched rules.

For example:

Go

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

Node.js

const ok = await e.enforceEx(request);

PHP

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

Python

ok, reason = e.enforce_ex(request)

EnforceExWithMatcher()

EnforceExWithMatcher use a custom matcher and explain enforcement by informing matched rules.

For example:

Go

ok, reason, err := e.EnforceExWithMatcher(matcher, request)

AddPolicies()

AddPolicies adds authorization 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 the authorization rules are consistent with the policy rules, the function returns true and each policy rule is added to the current policy.

For example:

.NET

var removed = e.RemoveFilteredNamedPolicy("p", 0, "alice", "data1", "read");
or
var removed = e.RemoveFilteredNamedPolicyAync("p", 0, "alice", "data1", "read");

Rust

let removed = e.remove_filtered_named_policy("p", 0, vec!["alice".to_owned(), "data1".to_owned(), "read".to_owned()]).await?;

Java

boolean removed = e.removeFilteredNamedPolicy("p", 0, "alice", "data1", "read");

HasGroupingPolicy()

HasGroupingPolicy determines whether a role inheritance rule exists.

For example:

Go

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

Node.js

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

PHP

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

Python

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

.NET

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

Rust

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

Java

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

HasNamedGroupingPolicy()

HasNamedGroupingPolicy determines whether a named role inheritance rule exists.

For example:

Go

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

Node.js

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

PHP

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

Python

has = e.has_named_grouping_policy("g", "alice", "data2_admin")

.NET

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

Rust

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

Java

boolean 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

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

Node.js

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

PHP

$added = $e->addGroupingPolicy("group1", "data2_admin");

Python

added = e.add_grouping_policy("group1", "data2_admin")

.NET

var added = e.AddGroupingPolicy("group1", "data2_admin");
or
var added = await e.AddGroupingPolicyAsync("group1", "data2_admin");

Rust

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

Java

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

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

areRulesAdded := e.AddGroupingPolicies(rules)

Node.js

const groupingRules = [
    ['ham', 'data4_admin'],
    ['jack', 'data5_admin']
  ];

const areRulesAdded = await e.addGroupingPolicies(groupingRules);

Python

rules = [
    ["ham", "data4_admin"],
    ["jack", "data5_admin"]
]

are_rules_added = e.add_grouping_policies(rules)

Rust

let rules = vec![
    vec!["ham".to_owned(), "data4_admin".to_owned()],
    vec!["jack".to_owned(), "data5_admin".to_owned()],
];

let areRulesAdded = e.add_grouping_policies(rules).await?;

Java

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

AddNamedGroupingPolicy()

Node.js

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

PHP

$added = $e->addNamedGroupingPolicy("g", "group1", "data2_admin");

Python

added = e.add_named_grouping_policy("g", "group1", "data2_admin")

.NET

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

Rust

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

Java

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.

Node.js

const groupingRules = [
    ['ham', 'data4_admin'],
    ['jack', 'data5_admin']
  ];

const areRulesAdded = await e.addNamedGroupingPolicies('g', groupingRules);

are_rules_added = e.add_named_grouping_policies("g", rules)

Rust

let rules = vec![
    vec!["ham".to_owned(), "data4_admin".to_owned()],
