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")

Enforce()​

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

Zum Beispiel:

ok, err := 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 "".

Zum Beispiel:

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

EnforceEx()​

EnforceEx explain enforcement by informing matched rules.

Zum Beispiel:

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

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.

Zum Beispiel:

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