- 从 OpenOcean API 获取报价,并根据 API 返回的原子单位数量和代币小数位数计算价格。
- 价格计算方式为: (通过 inAmount 和 inToken.decimals 计算得到的人类可读输入数量) / (通过 outAmount 和 outToken.decimals 计算得到的人类可读输出数量)
- 这个价格表示 “每单位输出代币需要多少单位输入代币”。
- Args:
- in_token_addr (str): 输入代币的合约地址。
- out_token_addr (str): 输出代币的合约地址。
- human_amount_in_decimal_for_request (decimal.Decimal): 用于 API 请求的人类可读的输入金额。
- API会根据此金额和实际代币信息处理请求。
- gas_price (int, optional): Gas 价格。 默认为 3。
