Types

type SessionStorage

type SessionStorage struct {
	// contains filtered or unexported fields
}

SessionStorage is a MTProto session S3 storage.

Example

package main

import (
	"context"
	"fmt"
	"os"
	"os/signal"

	"github.com/go-faster/errors"
	"github.com/minio/minio-go/v7"
	"github.com/minio/minio-go/v7/pkg/credentials"

	"github.com/gotd/td/telegram"

	"github.com/gotd/contrib/s3"
)

func s3Storage(ctx context.Context) error {
	accessKeyID := "Q3AM3UQ867SPQQA43P2F"
	secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"

	db, err := minio.New("play.min.io", &minio.Options{
		Creds: credentials.NewStaticV4(accessKeyID, secretAccessKey, ""),
	})
	if err != nil {
		return errors.Errorf("create s3 storage: %w", err)
	}
	storage := s3.NewSessionStorage(db, "telegram", "session")

	client, err := telegram.ClientFromEnvironment(telegram.Options{
		SessionStorage: storage,
	})
	if err != nil {
		return errors.Errorf("create client: %w", err)
	}

	return client.Run(ctx, func(ctx context.Context) error {
		_, err := client.Auth().Bot(ctx, os.Getenv("BOT_TOKEN"))
		return err
	})
}

func main() {
	ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt)
	defer cancel()

	if err := s3Storage(ctx); err != nil {
		_, _ = fmt.Fprintf(os.Stderr, "%+v\n", err)
		os.Exit(1)
	}
}

func NewSessionStorage

func NewSessionStorage(client *minio.Client, bucketName, objectName string) SessionStorage

NewSessionStorage creates new SessionStorage.

func (SessionStorage) LoadSession

func (s SessionStorage) LoadSession(ctx context.Context) ([]byte, error)

LoadSession implements session.Storage.

func (SessionStorage) StoreSession

func (s SessionStorage) StoreSession(ctx context.Context, data []byte) error

StoreSession implements session.Storage.
