Bitcoin bumpfee用法及代碼示例

{
  "confTarget": n,           (numeric, optional, default=fallback to wallet's default) Confirmation target (in blocks)
  "totalFee": n,             (numeric, optional, default=fallback to 'confTarget') Total fee (NOT feerate) to pay, in satoshis.
                             In rare cases, the actual fee paid might be slightly higher than the specified
                             totalFee if the tx change output has to be removed because it is too close to
                             the dust threshold.
  "replaceable": bool,       (boolean, optional, default=true) Whether the new transaction should still be
                             marked bip-125 replaceable. If true, the sequence numbers in the transaction will
                             be left unchanged from the original. If false, any input sequence numbers in the
                             original transaction that were less than 0xfffffffe will be increased to 0xfffffffe
                             so the new transaction will not be explicitly bip-125 replaceable (though it may
                             still be replaceable in practice, for example if it has unconfirmed ancestors which
                             are replaceable).
  "estimate_mode": "str",    (string, optional, default=UNSET) The fee estimate mode, must be one of:
                             "UNSET"
                             "ECONOMICAL"
                             "CONSERVATIVE"
}

{
  "txid":    "value",   (string)  The id of the new transaction
  "origfee":  n,         (numeric) Fee of the replaced transaction
  "fee":      n,         (numeric) Fee of the new transaction
  "errors":  [ str... ] (json array of strings) Errors encountered during processing (may be empty)
}
