本文介绍了Hyperledger锯齿JavaScript SDK:提交的批次无效的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试按照提交事务时,我从REST API中收到以下错误消息
While submitting the transaction I am getting the following error from REST API
{
"error": {
"code": 30,
"message": "The submitted BatchList was rejected by the validator. It was poorly formed, or has an invalid signature.",
"title": "Submitted Batches Invalid"
}
}
发现了以下与我的问题类似的问题
Found the following issue similar to my problem
但是在Java中实现的解决方案不适用于我的情况
But its implemented in java the solution not work for my case
推荐答案
这应该可行,请尝试以下操作:
This should work, try this:
const cbor = require('cbor');
const {createContext, CryptoFactory} = require('sawtooth-sdk/signing');
const {createHash} = require('crypto');
const {protobuf} = require('sawtooth-sdk');
const request = require('request');
const crypto = require('crypto');
const context = createContext('secp256k1');
const privateKey = context.newRandomPrivateKey();
const signer = CryptoFactory(context).newSigner(privateKey);
// Here's how you can generate the input output address
const FAMILY_NAMESPACE = crypto.createHash('sha512').update('intkey').digest('hex').toLowerCase().substr(0, 6);
const address = FAMILY_NAMESPACE + crypto.createHash('sha512').update('foo').digest('hex').toLowerCase().substr(0, 64);
const payload = {
Verb: 'set',
Name: 'foo',
Value: 42
};
const payloadBytes = cbor.encode(payload);
const transactionHeaderBytes = protobuf.TransactionHeader.encode({
familyName: 'intkey',
familyVersion: '1.0',
inputs: [address],
outputs: [address],
signerPublicKey: signer.getPublicKey().asHex(),
batcherPublicKey: signer.getPublicKey().asHex(),
dependencies: [],
payloadSha512: createHash('sha512').update(payloadBytes).digest('hex')
}).finish();
const transactionHeaderSignature = signer.sign(transactionHeaderBytes);
const transaction = protobuf.Transaction.create({
header: transactionHeaderBytes,
headerSignature: transactionHeaderSignature,
payload: payloadBytes
});
const transactions = [transaction]
const batchHeaderBytes = protobuf.BatchHeader.encode({
signerPublicKey: signer.getPublicKey().asHex(),
transactionIds: transactions.map((txn) => txn.headerSignature),
}).finish();
const batchHeaderSignature = signer.sign(batchHeaderBytes)
const batch = protobuf.Batch.create({
header: batchHeaderBytes,
headerSignature: batchHeaderSignature,
transactions: transactions
};
const batchListBytes = protobuf.BatchList.encode({
batches: [batch]
}).finish();
request.post({
url: 'http://rest.api.domain/batches',
body: batchListBytes,
headers: {'Content-Type': 'application/octet-stream'}
}, (err, response) => {
if(err) {
return console.log(err);
}
console.log(response.body);
});
