管理 API

提供对Casbin策略管理完全支持的基本API。

筛选的 API

几乎所有的带有过滤器的api有着相同的参数 (fieldIndex int, fieldValues ...string). field index 是匹配起始点的索引。 field Value 表示结果应该有的值。 请注意字段值中的空字符串可以是任意单词。

示例:

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

e.GetFilteredPolicy(1, "book") // 将返回：[Alice book read] [bob book read] [bob book write]]

e. etFilteredPolicy(1, "book", "read") // 将返回: [[Alice book read] [bob book read]]

etFilteredPolicy(0, "Alice", "", "read") // 将返回: [[Alice book read]]

e.GetFilteredPolicy(0, "Alice") // 将返回: [Alice book read] [Alice penge]]

参考

全局变量 e 是 Enforcer 实例。

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("exampes/ rbac_model.conf", "exampes/ rbac_policy.csv");

const ok = await e.enforce(request);
$ok = $e->enforcer($request);
ok = e.enforcer(request)
boolean ok = e.enforce(request);

EnforceWithMatcher()

例如：

ok, err := e.EnforceWithMatcher(matcher, request)
$ok = $e->enforceWithMatcher($matcher, $request);
ok = e.enforce_with_matcher(matcher, request)
boolean ok = e.enforceWithMatcher(matcher, request);

例如：

ok, reason, err := e.EnforceEx(request)
const ok = await e.enforceEx(request);
list($ok, $reason) = $e->enforceEx($request);
ok, reason = e.enforce_ex(request)

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

AddGroupingPolicies()

AddGroupingPolicy 向当前策略添加角色继承规则。 该操作本质上是原子的 因此，如果授权规则由不符合现行策略的规则组成， 函数返回false，当前策略中没有添加任何策略规则。 如果所有授权规则都符合策略规则，则函数返回true，每项策略规则都被添加到目前的策略中。

例如:

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);

AddNamedGroupingPolicy()

AddNamedGroupingPolicy 将命名角色继承规则添加到当前策略。 如果规则已经存在，函数返回false，并且不会添加规则。 否则，函数通过添加新规则并返回true。

例如:

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 将命名角色继承规则添加到当前策略。 该操作本质上是原子的 因此，如果授权规则由不符合现行策略的规则组成， 函数返回false，当前政策中没有添加任何策略规则。 如果所有授权规则都符合策略规则，则函数返回true，每项策略规则都被添加到目前的策略中。

例如:

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);

boolean removed = e.removeGroupingPolicy("alice", "data2_admin");

RemoveGroupingPolicies()

RemoveGroupingPolicy 从当前策略中删除角色继承规则。 该操作本质上是原子的 因此，如果授权规则由不符合现行策略的规则组成， 函数返回 false ，当前策略中没有任何策略规则被删除。 如果所有授权规则都符合策略规则，则函数返回true，每项策略规则都从现行策略中删除。

例如:

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

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

例如:

removed := e.RemoveFilteredGroupingPolicy(0, "alice")
const removed = await e.removeFilteredGroupingPolicy(0, 'alice')
$removed = $e->removeFilteredGroupingPolicy(0, "alice");
removed = e.remove_filtered_grouping_policy(0, "alice")
var removed = e.RemoveFilteredGroupingPolicy(0, "alice");
或者
var removed = await e.RemoveFilteredGroupingPolicyAsync(0, "alice");
let removed = e.remove_filtered_grouping_policy(0, vec!["alice".to_owned()]).await?;
boolean removed = e.removeFilteredGroupingPolicy(0, "alice");

例如:

removed := e.RemoveNamedGroupingPolicy("g", "alice")
const removed = await e.removeNamedGroupingPolicy('g', 'alice')
$removed = $e->removeNamedGroupingPolicy("g", "alice");
removed = e.remove_named_grouping_policy("g", "alice", "data2_admin")
