Authentication using a token

Note

The article is being updated.

Below are examples of the code for authentication using a token in different YDB SDKs.

  package main

  import (
    "context"
    "os"
    
    "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.WithAccessTokenCredentials(os.Getenv("YDB_TOKEN")),
  )
  if err != nil {
    panic(err)
  }
  defer db.Close(ctx)
  ...
}
If you use a connector to create a connection to YDB
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.WithAccessTokenCredentials(os.Getenv("YDB_TOKEN")),
  )
  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()
  ...
}
If you use a connection string
package main

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

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

func main() {
  db, err := sql.Open("ydb", "grpcs://localohost:2135/local?token="+os.Getenv("YDB_TOKEN"))
  if err != nil {
    panic(err)
  }
  defer db.Close()
  ...
}

public void work(String connectionString, String accessToken) {
    AuthProvider authProvider = new TokenAuthProvider(accessToken);

    GrpcTransport transport = GrpcTransport.forConnectionString(connectionString)
            .withAuthProvider(authProvider)
            .build();

    TableClient tableClient = TableClient.newClient(transport).build();

    doWork(tableClient);

    tableClient.close();
    transport.close();
}

import { Driver, TokenAuthService } from 'ydb-sdk';

export async function connect(endpoint: string, database: string, accessToken: string) {
    const authService = new TokenAuthService(accessToken);
    const driver = new Driver({endpoint, database, authService});
    const timeout = 10000;
    if (!await driver.ready(timeout)) {
        console.log(`Driver has not become ready in ${timeout}ms!`);
        process.exit(1);
    }
    console.log('Driver connected')
    return driver
}
