The steps i followed are i first load the wallet in a different method which works, then i check the balance of the wallet in a different method which works, and then I call this sendbitcoin method(below). I can see that the bitcoind server gets the message but it returns with a 500.
If i use bitcoin-cli it works however i need to add a -rpcwallet flag. It’s my understanding that since the wallet has been loaded i shouldn’t need to use flag. My wallets aren’t encrypted so i don’t believe i need to use a passphrase.
My bitcoin.conf file looks like this.
rpcuser=rpcuser
rpcpassword=rpcpassword
testnet=1
prune=550
server=1
dbcache=1000
[test]
debug=mempool
debug=rpc
dbcache=1000
rpcport=8332
rpcbind=0.0.0.0
rpcallowip=172.19.0.0/16
minconf=1
fallbackfee=0.00000001
And the method looks like.
func (w *Wallet) SendBitcoin(sendTo string, amount float64, coachID uint) (BitcoinTransaction, error) {
username := os.Getenv("RPC_USER")
password := os.Getenv("RPC_PASSWORD")
rpcURL := os.Getenv("BITCOIN_NODE_HOST")
if username == "" || password == "" || rpcURL == "" {
log.Error("RPC_USER, RPC_PASSWORD, or BITCOIN_NODE_HOST environment variables are not set")
return BitcoinTransaction{}, errors.New("RPC_USER, RPC_PASSWORD, or BITCOIN_NODE_HOST environment variables are not set")
}
// Prepare the RPC request payload
requestBody := map[string]interface{}{
"jsonrpc": "1.0",
"method": "sendtoaddress",
"params": []interface{}{sendTo, amount},
"id": 1,
}
logrus.Printf("request body : %v", requestBody)
logrus.Printf("Sending on wallet %v", w.Name)
jsonData, err := json.Marshal(requestBody)
if err != nil {
log.Errorf("failed to marshal JSON request: %v", err)
return BitcoinTransaction{}, fmt.Errorf("failed to marshal JSON request: %v", err)
}
logrus.Printf("JSON body : %v", jsonData)
client := &http.Client{}
req, err := http.NewRequest("POST", rpcURL, bytes.NewBuffer(jsonData))
if err != nil {
log.Errorf("failed to create HTTP request: %v", err)
return BitcoinTransaction{}, fmt.Errorf("failed to create HTTP request: %v", err)
}
req.SetBasicAuth(username, password)
req.Header.Set("Content-Type", "application/json")
// Send HTTP request
resp, err := client.Do(req)
if err != nil {
log.Errorf("failed to send HTTP request: %v", err)
return BitcoinTransaction{}, fmt.Errorf("failed to send HTTP request: %v", err)
}
//...
