删除用户和角色

为确保数据安全，建议你删除不再使用的用户和角色。本指南将介绍如何删除用户和角色。

删除用户

下面的示例演示了如何删除用户user_1 。

from pymilvus import MilvusClient

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

# create a user
client.drop_user(user_name="user_1")

import io.milvus.v2.client.ConnectConfig
import io.milvus.v2.client.MilvusClientV2
import io.milvus.v2.service.rbac.request.DropUserReq

ConnectConfig connectConfig = ConnectConfig.builder()
        .uri("http://localhost:19530")
        .token("root:Milvus")
        .build();
        
MilvusClientV2 client = new MilvusClientV2(connectConfig);

DropUserReq dropUserReq = DropUserReq.builder()
        .userName("user_1")
        .build();
client.dropUser(dropUserReq);

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.DropUser(ctx, milvusclient.NewDropUserOption("user_1"))
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});

milvusClient.deleteUser({
    username: 'user_1'
})

export CLUSTER_ENDPOINT="http://localhost:19530"
export TOKEN="root:Milvus"

curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/users/drop" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
--header "Request-Timeout: 10" \
-d '{
    "userName": "user_1"
}'

下拉用户后，可以列出所有现有用户，检查下拉操作是否成功。

from pymilvus import MilvusClient

client.list_users()

import io.milvus.v2.service.rbac.request.listUsersReq

List<String> resp = client.listUsers();

users, err := client.ListUsers(ctx, milvusclient.NewListUserOption())
if err != nil {
    fmt.Println(err.Error())
    // handle error
}

const { MilvusClient, DataType } = require("@zilliz/milvus2-sdk-node")

await milvusClient.listUsers();

curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/users/list" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
--header "Request-Timeout: 10" \
-d '{}'

下面是一个输出示例。列表中没有user_1 。下拉操作符成功。

['root']

删除角色

下面的示例演示了如何删除角色role_a 。

from pymilvus import MilvusClient

client.drop_role(role_name="role_a")

import io.milvus.v2.service.rbac.request.DropRoleReq

DropRoleReq dropRoleReq = DropRoleReq.builder()
        .roleName("role_a")
        .build();
client.dropRole(dropRoleReq);

err = client.DropRole(ctx, milvusclient.NewDropRoleOption("role_a"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}

const { MilvusClient, DataType } = require("@zilliz/milvus2-sdk-node")

await milvusClient.dropRole({
   roleName: 'role_a',
 });

curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/roles/drop" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
--header "Request-Timeout: 10" \
-d '{
    "roleName": "role_a"
}'

角色下拉后，您可以列出所有现有角色，以检查下拉操作是否成功。

from pymilvus import MilvusClient

client.list_roles()

List<String> resp = client.listRoles();

roles, err := client.ListRoles(ctx, milvusclient.NewListRoleOption())
if err != nil {
    fmt.Println(err.Error())
    // handle error
}

await client.listRoles({
    includeUserInfo: true
});

curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/roles/list" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
--header "Request-Timeout: 10" \
-d '{}'

下面是一个输出示例。列表中没有role_a 。下拉操作符成功。

['admin']
