Management API

The Management API provides comprehensive support for Casbin policy management operations.

Filtered API

Filtered API methods share a common parameter signature: (fieldIndex int, fieldValues ...string). The fieldIndex parameter specifies the starting index for matching, while fieldValues contains the expected values. Empty strings in fieldValues act as wildcards, matching any value.

Приклад:

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

Throughout this reference, the variable e represents an Enforcer instance.

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 вирішує, чи може "суб'єкт" отримати доступ до "об'єкта" з операцією "дія", зазвичай вхідні параметри: (sub, obj, act).

Наприклад:

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 "".

For example:

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.

For example:

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.

Наприклад:

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

var (ok, explain) = e.EnforceExWithMatcher(matcher, request);
// or async
var (ok, explain) = await e.EnforceExWithMatcherAsync(matcher, request);

BatchEnforce()

BatchEnforce enforces each request and returns result in a bool array

For example:

boolArray, err := e.BatchEnforce(requests)

const boolArray = await e.batchEnforce(requests);

var boolArray = e.BatchEnforce(requests);

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.

For example:

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

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

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

let added = e.add_policy(vec!["eve".to_owned(), "data3".to_owned(), "read".to_owned()]);

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.

For example:

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

areRulesAdded := e.AddPolicies(rules)

const rules = [

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

boolean areRulesAdded = e.addPolicies(rules);

AddPoliciesEx()

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

$added = $e->addNamedPolicy("p", "eve", "data3", "read");

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.

For example:

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

    vec!["katy".to_owned(), "data4".to_owned(), "write".to_owned()],
    vec!["leyo".to_owned(), "data4".to_owned(), "read".to_owned()],
    vec!["ham".to_owned(), "data4".to_owned(), "write".to_owned()],

    Arrays.asList("jack", "data4", "read"),
    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

For example:

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

For example:

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

RemovePolicy()

RemovePolicy removes an authorization rule from the current policy.

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.

For example:

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:

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.

For example:

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.

For example:

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"],
    ["jack", "data5_admin"]
]

are_rules_added = e.add_grouping_policies(rules)

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

For example:

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.AddNamedGroupingPolicy("g", "group1", "data2_admin")

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

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

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. 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:

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"]
]

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

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

let are_rules_added = e.add_named_grouping_policies("g", rules).await?;

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

AddNamedGroupingPoliciesEx()

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