签名器 API接口
SatoTx
我们部署了一个签名器 https://api.satotx.com ，可暂做测试，获取utxo的签名。支持的API如下：
一、 对“某UTXO”签名
URL中需要的参数为：
- txid: 产生UTXO的txid
- index: UTXO的output index
Body中需要的json参数为：
- txHex: 产生UTXO的rawtx内容
Request
- Method: POST
- URL:
/utxo/{txid}/{index}- 签名:
/utxo/4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b/0
- 签名:
- Headers：
Content-Type: application/json - Body:
{
"txHex": "01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff4d04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73ffffffff0100f2052a01000000434104678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5fac00000000"
}
Response
返回值 code == 0 为正确，其他都是错误
data包括字段为：
- pubKey: rabin签名的公钥，hex编码
- txId: 同输入参数
- index: 同输入参数
- byTxId: 空
- sigBE: 签名，大端字节序，hex编码
- padding: 签名的padding，hex编码
- payload: 签名的内容，hex编码
其中payload字节内容为：
txid, index, value, script
txid在payload中为原始字节序, index是小端4字节，value是小端8字节。
