如何使用nodejs中的bitcoin-core包將sendRawTransaction發送到bitcoind JSON-RPC

我正在嘗試做

sendrawtransaction <transaction_hex>

從nodejs使用比特幣核心包我做到了

npm install bitcoin-core --save

我已經有最新的bitcoind設置和執行，rpcusername並rpcpassword設置在bitcoin.conf

我目前的程式碼如下所示。

const Client = require('bitcoin-core');
const client = new Client({ username: 'adminuser', password : 'adminpassword'});

client.getInfo((error, help) => console.log(help));

我設法只得到回應getInfo

其他一切都給出empty output或undefined或null

到目前為止，我已經嘗試了很多這樣的變化

tx_hex = "0200000001949e0e3ac02fef76dffa8e2191ee0041f71a90c5ec9bbcba77db5f57e49fe6dd010000006b483045022100d6ac8520a1cfe80f6f3c2fbe6c3f903894203715928382e77c3c7ad0de74112502203c14601e5195dde88c9cc16c45dc273af168bd4fd03b6c045f832b7ba0134f8c012102183e719a510ff322fcb0dbfa279ef2500dd87c0b8c6184480846262e1949fbebfeffffff028bec0900000000001976a9141b0c5cb82d59cb2e07e8d5e343167fda48a9d60e88ace2920f00000000001976a9148108670170211830be2c3c557afe6bc2205d27de88ac864a0700" 

client.sendRawTransaction((tx_hex,response) => console.log(response));

client.sendRawTransaction((tx_hex) => console.log());

client.sendRawTransaction((tx_hex), function(){console.log()});

但以上都沒有給出確認，也沒有給出正確的輸出。

我在這裡想念什麼？

我的意思是，如果我bitcoin-cli在終端上使用它會返回txhash。

例如

[root@localhost deploy]# bitcoin-cli sendrawtransaction 0200000001949e0e3ac02fef76dffa8e2191ee0041f71a90c5ec9bbcba77db5f57e49fe6dd010000006b483045022100d6ac8520a1cfe80f6f3c2fbe6c3f903894203715928382e77c3c7ad0de74112502203c14601e5195dde88c9cc16c45dc273af168bd4fd03b6c045f832b7ba0134f8c012102183e719a510ff322fcb0dbfa279ef2500dd87c0b8c6184480846262e1949fbebfeffffff028bec0900000000001976a9141b0c5cb82d59cb2e07e8d5e343167fda48a9d60e88ace2920f00000000001976a9148108670170211830be2c3c557afe6bc2205d27de88ac864a0700

更新1：

tx_hex = "0200000001949e0e3ac02fef76dffa8e2191ee0041f71a90c5ec9bbcba77db5f57e49fe6dd010000006b483045022100d6ac8520a1cfe80f6f3c2fbe6c3f903894203715928382e77c3c7ad0de74112502203c14601e5195dde88c9cc16c45dc273af168bd4fd03b6c045f832b7ba0134f8c012102183e719a510ff322fcb0dbfa279ef2500dd87c0b8c6184480846262e1949fbebfeffffff028bec0900000000001976a9141b0c5cb82d59cb2e07e8d5e343167fda48a9d60e88ace2920f00000000001976a9148108670170211830be2c3c557afe6bc2205d27de88ac864a0700" 

client.sendRawTransaction((tx_hex,response) => console.log(tx_hex + ':' + response));

返回

RpcError: -1 sendrawtransaction "hexstring" ( allowhighfees )

Submits raw transaction (serialized, hex-encoded) to local node and network.

Also see createrawtransaction and signrawtransaction calls.

Arguments:
1. "hexstring"    (string, required) The hex string of the raw transaction)
2. allowhighfees    (boolean, optional, default=false) Allow high fees

Result:
"hex"             (string) The transaction hash in hex

Examples:

Create a transaction
> bitcoin-cli createrawtransaction "[{\"txid\" : \"mytxid\",\"vout\":0}]" "{\"myaddress\":0.01}"
Sign the transaction, and get back the hex
> bitcoin-cli signrawtransaction "myhex"

Send the transaction (signed hex)
> bitcoin-cli sendrawtransaction "signedhex"

As a json rpc call
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "sendrawtransaction", "params": ["signedhex"] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
:undefined

你傳遞參數的方式是錯誤的。我使用下面的程式碼，得到了正確的答案：

const Client = require('bitcoin-core');
const client = new Client({username: 'admin', password: 'password', network: 'testnet'})

const txHex = '0200000001999539009d0d02f2332d257716faa75cc4c9a8318c153ba6a084c719fa33103b000000006a4730440220032470b6b45825fc37d08e1985c7ad2044272edacfa2c76cf49c6b70c09a0dac02202466ede3e660c6d57f65b7ed21f2c1f778116ef92bef9ed2f9b18fcb1881a7b9012103b91ff254ae3bb3861e4a6c16ab356d6c52ccfd2b58bedf0dda84657dfd9d9afcffffffff0130750000000000001976a914ba05ece7632d78336848214b525cfdbd1c4b06a188ac00000000'

client.sendRawTransaction(txHex, (error, response) => {
 if (error) console.log(error);
 console.log(response);
});
