}请求参数
string
需要估算最佳优先费的 Base58 或 Base64 编码 Solana 交易。
API 将分析此交易中的具体指令和账户，并根据当前网络状况和计算复杂度
提供准确的费用估算。如果该估算将用于设置你即将发送的交易费用，建议使用此参数。
如果同时省略此参数和 accountKeys，则会根据近期所有网络活动获取全局估算；
该估算反映的是网络状况，而不是你的交易情况。
array
需要估算优先费的 Solana 账户公钥数组（可替代提供交易）。
请包含你的交易将锁定的可写账户：Solana 按可写账户计算优先费，
因此这些账户就是你需要竞争的对象。
object
根据网络状况自定义Solana优先费用估算的高级选项
string
提供的Solana交易的编码格式
Base58Base64
string
基于当前Solana网络拥堵估算费用的特定优先级别
MinLowMediumHighVeryHighUnsafeMax
boolean
如果为true，则返回从最小到最大优先级别的全面估算
number
分析最近的Solana区块链槽数以进行准确的费用估算(1-150)
boolean
如果为true，则在费用计算中包括投票交易，以便进行更全面的分析
boolean
如果为true，则根据当前的Solana网络状况返回推荐的最佳费用
boolean
如果为true，则在计算中将没有交易的槽视为零费用槽
