Websocket subscription gets closed after a few minutes
tajelp opened this issue · comments
Hello there, I am trying to get transactions data in real-time with the official go sdk. Everything is okay except for the fact that the wss seems to get interrupted after a few minutes, so I am not able to get new data anymore and I would have to constantly restart the script. Here's the relevant code:
package main
import (
"encoding/base64"
"encoding/json"
"fmt"
"github.com/bnb-chain/go-sdk/client/rpc"
"github.com/bnb-chain/go-sdk/types"
"github.com/bnb-chain/go-sdk/types/tx"
ctypes "github.com/bnb-chain/go-sdk/common/types"
"github.com/bnb-chain/go-sdk/keys"
"time"
"reflect"
)
type EventData struct {
Tx string `json:"tx"`
}
type Input struct {
Address string `json:"address"`
Coins []struct {
Denom string `json:"denom"`
Amount int64 `json:"amount"`
} `json:"coins"`
}
type Output struct {
Address string `json:"address"`
Coins []struct {
Denom string `json:"denom"`
Amount int64 `json:"amount"`
} `json:"coins"`
}
type Msg struct {
Inputs []Input `json:"inputs"`
Outputs []Output `json:"outputs"`
}
type DecodedTx struct {
Msg []Msg `json:"msg"`
Signatures []struct {
PubKey string `json:"pub_key"`
Signature string `json:"signature"`
AccountNum int64 `json:"account_number"`
Sequence int64 `json:"sequence"`
} `json:"signatures"`
Memo string `json:"memo"`
Source int64 `json:"source"`
Data interface{} `json:"data"`
}
type Coins []Coin
type Coin struct {
Denom string `json:"denom"`
Amount int64 `json:"amount"`
}
func scanMempool() {
BNBClient = rpc.NewRPCClient("dataseed1.binance.org:80", ctypes.ProdNetwork)
query := "tm.event = 'Tx'"
events, err := BNBClient.Subscribe(query, 100)
if err != nil {
fmt.Println("Error while subscribing", err)
return
}
for event := range events {
fmt.Printf("[%s] new event\n", time.Now().UTC().Format("2006-01-02 15:04:05 GMT"))
eventDataBytes, err := json.Marshal(event.Data)
if err != nil {
fmt.Println("Error converting TMEventData to bytes:", err)
continue
}
var eventData EventData
err = json.Unmarshal(eventDataBytes, &eventData)
if err != nil {
fmt.Println("Error unmarshaling event data:", err)
continue
}
txBytes, err := base64.StdEncoding.DecodeString(eventData.Tx)
if err != nil {
fmt.Println("error:", err)
continue
}
txs := []string{
string(txBytes),
}
codec := types.NewCodec()
parsedTxs := make([]tx.StdTx, len(txs))
for i := range txs {
err := codec.UnmarshalBinaryLengthPrefixed([]byte(txs[i]), &parsedTxs[i])
if err != nil {
fmt.Println("Failed to unmarshal transaction:", err)
continue
}
// Extract and print the inputs and destination address
for _, tx := range parsedTxs {
txBytes, err := json.Marshal(tx)
if err != nil {
fmt.Println("Failed to marshal transaction:", err)
continue
}
var decodedTx DecodedTx
err = json.Unmarshal(txBytes, &decodedTx)
if err != nil {
fmt.Println("Failed to unmarshal decoded transaction:", err)
continue
}
for _, msg := range decodedTx.Msg {
for _, input := range msg.Inputs {
fmt.Println("Input Address:", input.Address)
for _, coin := range input.Coins {
fmt.Println("Coin Denom:", coin.Denom)
fmt.Println("Coin Amount:", coin.Amount)
}
}
for _, output := range msg.Outputs {
fmt.Println("Output Address:", output.Address)
}
}
fmt.Println("-")
}
}
}
}
And here's a sample output:

-

-
[2023-08-15 12:03:50 GMT] new event

Then I get no more events, all stuck. Why? Can somebody help me, please?
