为角色授予权限或权限组

创建角色后，就可以向角色授予权限。本指南将介绍如何向角色授予权限或权限组。

向角色授予权限或权限组​

Milvus 2.5 引入了新版本的 API，简化了授予操作。向角色授予权限时，不再需要查找对象类型。以下是参数和相应的解释。

  • **role_name：**需要授予权限或权限组的目标角色名称。

  • 资源：权限的目标资源，可以是特定实例、数据库或 Collection。

下表解释了如何在client.grantV2() 方法中指定资源。

|

 client.grant_privilege_v2(
     role_name="roleA",
     privilege="DatabaseAdmin",
     collection_name="*",
     db_name="*"
 )

|

下面的示例演示了如何在default 数据库下的collection_01 上授予PrivilegeSearch 权限，以及如何将名为privilege_group_1 的特权组授予角色role_a 。

from pymilvus import MilvusClient

client = MilvusClient(
    uri="http://localhost:19530",
    token="root:Milvus"
)

client.grant_privilege_v2(
    role_name="role_a",
    privilege="Search",
    collection_name='collection_01',
    db_name='default',
)

client.grant_privilege_v2(
    role_name="role_a",
    privilege="privilege_group_1",
    collection_name='collection_01',
    db_name='default',
)

client.grant_privilege_v2(
    role_name="role_a",
    privilege="ClusterReadOnly",
    collection_name='*',
    db_name='*',
)
import io.milvus.v2.service.rbac.request.GrantPrivilegeReqV2

client.grantPrivilegeV2(GrantPrivilegeReqV2.builder()
        .roleName("role_a")
        .privilege("Search")
        .collectionName("collection_01")
        .dbName("default")
        .build());

client.grantPrivilegeV2(GrantPrivilegeReqV2.builder()
        .roleName("role_a")
        .privilege("privilege_group_1")
        .collectionName("collection_01")
        .dbName("default")
        .build());

client.grantPrivilegeV2(GrantPrivilegeReqV2.builder()
        .roleName("role_a")
        .privilege("ClusterReadOnly")
        .collectionName("*")
        .dbName("*")
        .build());
import (
    "context"
    "fmt"

    "github.com/milvus-io/milvus/client/v2/milvusclient"
)

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

client, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
    Address: "localhost:19530",
    APIKey:  "root:Milvus",
})
if err != nil {
    fmt.Println(err.Error())
    // handle error
}
defer client.Close(ctx)

err = client.GrantV2(ctx, milvusclient.NewGrantV2Option("role_a", "Search", "default", "collection_01"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}

err = client.GrantV2(ctx, milvusclient.NewGrantV2Option("role_a", "privilege_group_1", "default", "collection_01"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}

err = client.GrantV2(ctx, milvusclient.NewGrantV2Option("role_a", "ClusterReadOnly", "*", "*"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}
const { MilvusClient, DataType } = require("@zilliz/milvus2-sdk-node")

const address = "http://localhost:19530";
const token = "root:Milvus";
const client = new MilvusClient({address, token});

await client.grantPrivilegeV2({
    role: "role_a",
    privilege: "Search"
    collection_name: 'collection_01'
    db_name: 'default',
});

await client.grantPrivilegeV2({
    role: "role_a",
    privilege: "privilege_group_1"
    collection_name: 'collection_01'
    db_name: 'default',
});

await client.grantPrivilegeV2({
    role: "role_a",
    privilege: "ClusterReadOnly"
    collection_name: '*'
    db_name: '*',
});

描述角色​

下面的示例演示了如何使用describe_role 方法查看授予角色role_a 的权限。

from pymilvus import MilvusClient

client.describe_role(role_name="role_a")
import io.milvus.v2.service.rbac.response.DescribeRoleResp;
import io.milvus.v2.service.rbac.request.DescribeRoleReq

DescribeRoleReq describeRoleReq = DescribeRoleReq.builder()
        .roleName("role_a")
        .build();
DescribeRoleResp resp = client.describeRole(describeRoleReq);
List<DescribeRoleResp.GrantInfo> infos = resp.getGrantInfos();
import "github.com/milvus-io/milvus/client/v2/milvusclient"

role, err := client.DescribeRole(ctx, milvusclient.NewDescribeRoleOption("role_a"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}
await client.describeRole({roleName: 'role_a'});
curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/roles/describe" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
--header "Request-Timeout: 10" \
-d '{
    "roleName": "role_a"
}'

下面是一个输出示例。

{
     "role": "role_a",
     "privileges": [
         {
             "collection_name": "collection_01",
             "db_name": "default",
             "role_name": "role_a",
             "privilege": "Search",
             "grantor_name": "root"
         },
         "privilege_group_1"
     ]
}

撤销角色的权限或权限组​

下面的示例演示了如何撤销default 数据库下collection_01 的特权PrivilegeSearch 以及授予角色role_a 的特权组privilege_group_1 。

client.revoke_privilege_v2(
    role_name="role_a",
    privilege="Search",
    collection_name='collection_01',
    db_name='default',
)

client.revoke_privilege_v2(
    role_name="role_a",
    privilege="privilege_group_1",
    collection_name='collection_01',
    db_name='default',
)

client.revoke_privilege_v2(
    role_name="role_a",
    privilege="ClusterReadOnly",
    collection_name='*',
    db_name='*',
)
import io.milvus.v2.service.rbac.request.RevokePrivilegeReqV2

client.revokePrivilegeV2(RevokePrivilegeReqV2.builder()
        .roleName("role_a")
        .privilege("Search")
        .collectionName("collection_01")
        .dbName("default")
        .build());

client.revokePrivilegeV2(RevokePrivilegeReqV2.builder()
        .roleName("role_a")
        .privilege("privilege_group_1")
        .collectionName("collection_01")
        .dbName("default")
        .build());

client.revokePrivilegeV2(RevokePrivilegeReqV2.builder()
        .roleName("role_a")
        .privilege("ClusterReadOnly")
        .collectionName("*")
        .dbName("*")
        .build());
err = client.RevokePrivilegeV2(ctx, milvusclient.NewRevokePrivilegeV2Option("role_a", "Search", "collection_01").
        WithDbName("default"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}

err = client.RevokePrivilegeV2(ctx, milvusclient.NewRevokePrivilegeV2Option("role_a", "privilege_group_1", "collection_01").
    WithDbName("default"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}

err = client.RevokePrivilegeV2(ctx, milvusclient.NewRevokePrivilegeV2Option("role_a", "ClusterReadOnly", "*").
    WithDbName("*"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}
await client.revokePrivilegeV2({
    role: 'role_a',
    privilege: 'Search',
    collection_name: 'collection_01',
    db_name: 'default'
});

await client.revokePrivilegeV2({
    role: 'role_a',
    collection_name: 'collection_01',
    privilege: 'Search',
    db_name: 'default'
});

await client.revokePrivilegeV2({
    role: 'role_a',
    collection_name: '*',
    privilege: 'ClusterReadOnly',
    db_name: '*'
});
curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/roles/revoke_privilege_v2" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
--header "Request-Timeout: 10" \
-d '{
    "roleName": "role_a",
    "privilege": "Search",
    "collectionName": "collection_01",
    "dbName":"default"
}'

--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
--header "Request-Timeout: 10" \
-d '{
    "roleName": "role_a",
    "privilege": "Search",
    "collectionName": "collection_01",
    "dbName":"default"
}'
