如何批量转账呢？ 如何构造多个输出地址呢？

目前还没有现成的批量转账功能。
如果现在要用的话，需要写代码。
可以参考 ruby sdk现有构造交易的代码

尝试写了下代码 提示
CKB::RPCError {:code=>-3, :message=>"InvalidTx(ScriptFailure(ValidationFailure(-2)))"}

code


    def send_capacities(_addrs, capacities, data = "0x")
      raise "addrs.size != capacities.size" if _addrs.size != capacities.size

      _sum = capacities.sum()
      i = gather_inputs(_sum, MIN_CELL_CAPACITY)
      input_capacities = i.capacities

      outputs = []

      _addrs.each_with_index do | addr, inx|

       outputs << Types::Output.new(
          capacity: capacities[inx],
          data: data,
          lock: Types::Script.generate_lock(
            key.address.parse(addr),
            api.system_script_code_hash
          )
        )
      end

      if input_capacities > _sum
        outputs << Types::Output.new(
          capacity: input_capacities - _sum,
          lock: lock
        )
      end

      tx = Types::Transaction.new(
        version: 0,
        deps: [api.system_script_out_point],
        inputs: i.inputs,
        outputs: outputs
      )

      tx_hash = api.compute_transaction_hash(tx)
      tx.sign(key, tx_hash)

      send_transaction(tx)
