Types ¶
type Codec ¶
type Codec interface {
// WriteHeader sends protocol tag if needed.
WriteHeader(w io.Writer) error
// ReadHeader reads protocol tag if needed.
ReadHeader(r io.Reader) error
// Write encode to writer message from given buffer.
Write(w io.Writer, b *bin.Buffer) error
// Read fills buffer with received message.
Read(r io.Reader, b *bin.Buffer) error
}
Codec is MTProto transport protocol encoding abstraction.
type Conn ¶ added in v0.12.0
type Conn interface {
Send(ctx context.Context, b *bin.Buffer) error
Recv(ctx context.Context, b *bin.Buffer) error
Close() error
}
Conn is transport connection.
type DialFunc ¶
DialFunc is functional helper for Dialer.
Example ¶
package main
import (
"context"
"fmt"
"time"
"golang.org/x/net/proxy"
"github.com/gotd/td/telegram"
"github.com/gotd/td/transport"
)
func main() {
trp := transport.Intermediate(transport.DialFunc(proxy.Dial))
// Creating connection.
ctx, cancel := context.WithTimeout(context.Background(), time.Second*5)
defer cancel()
client := telegram.NewClient(1, "appHash", telegram.Options{
Transport: trp,
})
_ = client.Run(ctx, func(ctx context.Context) error {
fmt.Println("Started")
return nil
})
}
Output:
type Dialer ¶
type Dialer interface {
DialContext(ctx context.Context, network, address string) (net.Conn, error)
}
Dialer dials using a context.
type Server ¶
type Server struct {
// contains filtered or unexported fields
}
Server is a simple MTProto server.
func NewCustomServer ¶
NewCustomServer creates new MTProto server with custom transport codec.
func NewFullServer ¶ added in v0.12.0
NewFullServer creates new MTProto server with Full transport codec.
func NewIntermediateServer ¶
NewIntermediateServer creates new MTProto server with Intermediate transport codec.
type Transport ¶
type Transport struct {
// contains filtered or unexported fields
}
Transport is MTProto connection creator.
func Abridged ¶ added in v0.14.0
Abridged creates Abridged transport.
See https://core.telegram.org/mtproto/mtproto-transports#abridged
func Full ¶
Full creates Full transport.
See https://core.telegram.org/mtproto/mtproto-transports#full
func Intermediate ¶
Intermediate creates Intermediate transport.
See https://core.telegram.org/mtproto/mtproto-transports#intermediate
func MTProxy ¶ added in v0.14.0
MTProxy creates MTProxy obfuscated transport.
See https://core.telegram.org/mtproto/mtproto-transports#transport-obfuscation
Example ¶
package main
import (
"context"
"encoding/hex"
"fmt"
"os"
"time"
"github.com/gotd/td/telegram"
"github.com/gotd/td/transport"
)
func main() {
addr, ok := os.LookupEnv("MTPROXY_ADDR")
if !ok {
fmt.Println("MTPROXY_ADDR is not set")
return
}
secret, err := hex.DecodeString(os.Getenv("MTPROXY_SECRET"))
if err != nil {
panic(err)
}
trp, err := transport.MTProxy(nil, 2, secret)
if err != nil {
panic(err)
}
// Creating connection.
ctx, cancel := context.WithTimeout(context.Background(), time.Second*5)
defer cancel()
client := telegram.NewClient(1, "appHash", telegram.Options{
Addr: addr,
Transport: trp,
})
_ = client.Run(ctx, func(ctx context.Context) error {
fmt.Println("Started")
return nil
})
}
Output:
func NewTransport ¶ added in v0.12.0
NewTransport creates transport using user Codec constructor.
func PaddedIntermediate ¶ added in v0.14.0
PaddedIntermediate creates Padded intermediate transport.
See https://core.telegram.org/mtproto/mtproto-transports#padded-intermediate
func (*Transport) DialContext ¶
DialContext creates new MTProto connection.
