响应参数#
| 参数名称 | 相关描述 | 数据类型 |
|---|---|---|
| dataList | Call data 数据信息 | Array[Struct] |
| >from | 发送地址 (用户地址) | String |
| >to | 接受地址 (目标合约地址) | String |
| >value | 转账金额 (原生代币数量，默认为空字符串) | String |
| >serializedData | Call data 数据 | String |
| >originalData | 原始数据 (JSON) | JSON String |
| >callDataType | 操作类型 (授权、申购、赎回、领取) | String |
| >signatureData | 签名 Call data 数据信息，可用于验证数据由欧易生成 | String |
备注：#
验签方法：
- 使用 signatureData 签名信息计算出 r、s、v。
- 与 to + serializedData + originalData 拼接成的字符串计算出验签 hash。
- 恢复公钥验证。可由接入客户选则是否验签，如果验签成功，则说明该数据由欧易签名生成。
