Management API

The Management API covers all policy and grouping (role) operations: get, add, remove, update, filter. Below, e is an Enforcer instance.

Filtered API

Filtered methods take (fieldIndex int, fieldValues ...string): matching starts at fieldIndex, and fieldValues are the required values at consecutive positions. Use "" in fieldValues as a wildcard for that position.

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") // returns: [["alice", "book", "read"], ["bob", "book", "read"], ["bob", "book", "write"]]

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

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

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

API Reference

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).

Par exemple :

ok, err := e.Enforce(request)

const ok = await e.enforce(request);

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

ok = e.enforcer(request)

var ok = e.Enforce(request);
// or async
var ok = await e.EnforceAsync(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 "".

Par exemple :

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

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

ok = e.enforce_with_matcher(matcher, request)

var ok = e.EnforceWithMatcher(matcher, request);
// or async
var ok = await e.EnforceWithMatcherAsync(matcher, request);

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

EnforceEx()

EnforceEx explain enforcement by informing matched rules.

Par exemple :

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

const ok = await e.enforceEx(request);

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

var (ok, explain) = e.EnforceEx(request);
// or async
var (ok, explain) = await e.EnforceExAsync(request);

ok, reason = e.enforce_ex(request)

EnforceExWithMatcher()

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

Par exemple :

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

AddPolicy()

AddPolicy adds an authorization 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.

Par exemple :

added := e.AddPolicy('eve', 'data3', 'read')

const p = ['eve', 'data3', 'read']
const added = await e.addPolicy(...p)

$added = $e->addPolicy('eve', 'data3', 'read');

boolean added = e.addPolicy("eve", "data3", "read");

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.

Par exemple :

rules := [][] string {
    []string {"jack", "data4", "read"},
    []string {"katy", "data4", "write"},
    []string {"leyo", "data4", "read"},
    []string {"ham", "data4", "write"},

    {"ham", "data4", "write"},
};

boolean areRulesAdded = e.addPolicies(rules);

boolean added = e.addNamedPolicy("p", "eve", "data3", "read");

AddNamedPolicies()

AddNamedPolicies adds authorization rules to the current named 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.

Par exemple :

rules := [][] string {
    []string {"jack", "data4", "read"},
    []string {"katy", "data4", "write"},

    Arrays.asList("katy", "data4", "write"),
    Arrays.asList("leyo", "data4", "read"),
    Arrays.asList("ham", "data4", "write")
);
boolean areRulesAdded = e.addNamedPolicies("p", rules);

AddNamedPoliciesEx()

AddNamedPoliciesEx adds authorization rules to the current named policy. If the rule already exists, the rule will not be added. But unlike AddNamedPolicies, other non-existent rules are added instead of returning false directly

ok, err := e.AddNamedPoliciesEx("p", [][]string{{"user1", "data1", "read"}, {"user2", "data2", "read"}})

SelfAddPoliciesEx()

SelfAddPoliciesEx adds authorization rules to the current named policy with autoNotifyWatcher disabled. If the rule already exists, the rule will not be added. But unlike SelfAddPolicies, other non-existent rules are added instead of returning false directly

Par exemple :

ok, err := e.SelfAddPoliciesEx("p", "p", [][]string{{"user1", "data1", "read"}, {"user2", "data2", "read"}})

RemovePolicy()

RemovePolicy removes an authorization rule from the current policy.

boolean removed = e.removePolicy("alice", "data1", "read");

RemovePolicies()

RemovePolicies removes authorization rules from 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 removed from the current policy. If all the authorization rules are consistent with the policy rules, the function returns true and each policy rule is removed from the current policy.

Par exemple :

$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.

Par exemple :

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

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

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

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

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

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

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.

Par exemple :

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

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

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

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

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

Par exemple :

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

areRulesAdded := e.AddGroupingPolicies(rules)

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

const areRulesAdded = await e.addGroupingPolicies(groupingRules);

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

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?;

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

AddGroupingPoliciesEx()

AddGroupingPoliciesEx adds role inheritance rules to the current policy. If the rule already exists, the rule will not be added. But unlike AddGroupingPolicies, other non-existent rules are added instead of returning false directly

Par exemple :

ok, err := e.AddGroupingPoliciesEx([][]string{{"user1", "member"}, {"user2", "member"}})

AddNamedGroupingPolicy()

AddNamedGroupingPolicy adds a named 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.

added = e.add_named_grouping_policy("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.

Par exemple :

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

areRulesAdded := e.AddNamedGroupingPolicies("g", rules)

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

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

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

    {"jack", "data5_admin"}
};
boolean areRulesAdded = e.addNamedGroupingPolicies("g", groupingRules);

AddNamedGroupingPoliciesEx()
