我必须在testnet上签署原始交易,其十六进制如下所示,我尝试对交易生成部分中的所有内容进行硬编码,它可以正确广播。 但我必须分别实现交易和签名部分。 我正在使用bitcore-lib-cash包
const bitcore = require('bitcore-lib-cash')
const txhex = 010000000139a7e6578a862a10151bdbe0ed4a833cd615273b0cd0ecda1616ee8407d7d8040000000000ffffffff0241010000000000001976a914f0ac6825bd05b406d5224eab0be73852a487e06c88ac94dc0100000000001976a914185ec62d62510d40795109e6484e0487c28a3caf88ac00000000
const private_key = 'private key here'
let transaction = new bitcore.Transaction(txbuffer).sign(private_key)
console.log(private_key)
{
"errorMessage": "Invalid state: Not all utxo information is available to sign the transaction.",
"errorType": "bitcore.ErrorInvalidState",
"stackTrace": [

答案 0 :(得分:0)
我刚刚检查了bitcore-lib-cash的源代码,当调用toString
或toBuffer
函数时,它们并未对input
中的每个字段进行编码。
这是对input
进行编码的过程之一:
Input.prototype.toBufferWriter = function(writer) {
if (!writer) {
writer = new BufferWriter();
}
writer.writeReverse(this.prevTxId);
writer.writeUInt32LE(this.outputIndex);
var script = this._scriptBuffer;
writer.writeVarintNum(script.length);
writer.write(script);
writer.writeUInt32LE(this.sequenceNumber);
return writer;
};
所以我认为您必须重写此toBufferWriter
函数或解析txhex中的每个字段,然后再次重建事务。
您的txhex无效。
解码txhex之后,它在每个UTXO输入对象中都应该有一个output
字段,这就是错误的出处。
