Анонимная аутентификация

Ниже приведены примеры кода анонимной аутентификации в разных YDB SDK.

Java

JavaScript

Python

C# (.NET)

Rust

PHP

Native SDK

database/sql

Анонимная аутентификация является аутентификацией по умолчанию.
Явным образом анонимную аутентификацию можно включить так:

package main

import (
  "context"

  "github.com/ydb-platform/ydb-go-sdk/v3"
)

func main() {
  ctx, cancel := context.WithCancel(context.Background())
  defer cancel()
  db, err := ydb.Open(ctx,
    os.Getenv("YDB_CONNECTION_STRING"),
    ydb.WithAnonymousCredentials(),
  )
  if err != nil {
    panic(err)
  }
  defer db.Close(ctx)
  ...
}

package main

import (
  "context"
  "database/sql"
  "os"

  "github.com/ydb-platform/ydb-go-sdk/v3"
)

func main() {
  ctx, cancel := context.WithCancel(context.Background())
  defer cancel()
  nativeDriver, err := ydb.Open(ctx,
    os.Getenv("YDB_CONNECTION_STRING"),
    ydb.WithAnonymousCredentials(),
  )
  if err != nil {
    panic(err)
  }
  defer nativeDriver.Close(ctx)
  connector, err := ydb.Connector(nativeDriver)
  if err != nil {
    panic(err)
  }
  db := sql.OpenDB(connector)
  defer db.Close()
  ...
}

Native SDK

JDBC

public void work(String connectionString) {
    AuthProvider authProvider = NopAuthProvider.INSTANCE;

    try (GrpcTransport transport = GrpcTransport.forConnectionString(connectionString)
            .withAuthProvider(authProvider)
            .build();
         QueryClient queryClient = QueryClient.newClient(transport).build()) {

        doWork(queryClient);
    }
}

public void work() throws SQLException {
    // Подключение без дополнительных опций — с анонимной аутентификацией
    try (Connection connection = DriverManager.getConnection("jdbc:ydb:grpc://localhost:2136/local")) {
        doWork(connection);
    }
}

В Spring Boot, ORM и прочих сторонних фреймворках вокруг JDBC подключение задаётся той же JDBC-строкой подключения, что и выше (например, spring.datasource.url).

import { Driver } from "@ydbjs/core";
import { AnonymousCredentialsProvider } from "@ydbjs/auth/anonymous";

const driver = new Driver("grpc://localhost:2136/local", {
  credentialsProvider: new AnonymousCredentialsProvider(),
});

await driver.ready();

Native SDK (Asyncio)

SQLAlchemy

import os
import ydb

with ydb.Driver(
    connection_string=os.environ["YDB_CONNECTION_STRING"],
    credentials=ydb.credentials.AnonymousCredentials(),
) as driver:
    driver.wait(timeout=5)
    ...

import os
import ydb
import asyncio

async def ydb_init():
    async with ydb.aio.Driver(
        endpoint=os.environ["YDB_ENDPOINT"],
        database=os.environ["YDB_DATABASE"],
        credentials=ydb.credentials.AnonymousCredentials(),
    ) as driver:
        await driver.wait()
        ...

asyncio.run(ydb_init())

import sqlalchemy as sa

engine = sa.create_engine("yql+ydb://localhost:2136/local")
with engine.connect() as connection:
    result = connection.execute(sa.text("SELECT 1"))

using Ydb.Sdk;
using Ydb.Sdk.Auth;

const string endpoint = "grpc://localhost:2136";
const string database = "/local";

var config = new DriverConfig(
    endpoint: endpoint,
    database: database,
    credentials: new AnonymousProvider()
);

await using var driver = await Driver.CreateInitialized(config);

use ydb::{AnonymousCredentials, ClientBuilder, YdbResult};

let client = ClientBuilder::new_from_connection_string("grpc://localhost:2136?database=local")?
    .with_credentials(AnonymousCredentials::new())
    .client()?;

<?php

use YdbPlatform\Ydb\Ydb;
use YdbPlatform\Ydb\Auth\Implement\AnonymousAuthentication;

$config = [

    // Database path
    'database'    => '/local',

    // Database endpoint
    'endpoint'    => 'localhost:2136',

    // Auto discovery (dedicated server only)
    'discovery'   => false,

    // IAM config
    'iam_config'  => [
        'insecure' => true,
        // 'root_cert_file' => './CA.pem', // Root CA file (uncomment for dedicated server)
    ],

    'credentials' => new AnonymousAuthentication()
];

$ydb = new Ydb($config);
