hyperledger - 锯齿交易有效负载解码

Question

我在 Sawtooth 上触发了一笔交易。我可以使用 API 查看交易数据。我的问题是如何解码交易有效负载。

      "payload": "o2RWZXJiY3NldGROYW1leCBlZjlkMThjZGIwYjNkZDNmNWU1ZWE2MDliZjY3MDhmOWVWYWx1ZWA="
    }

我想解码有效负载": "o2RWZXJiY3NldGROYW1leCBlZjlkMThjZGIwYjNkZDNmNWU1ZWE2MDliZjY3MDhmOWVWYWx1ZWA="。
谁能指导一下。

Answer 1

锯齿rest-api返回base64编码的数据，首先你必须解码你的数据，

    import base64
    decoded = base64.b64decode("o2RWZXJiY3NldGROYW1leCBlZjlkMThjZGIwYjNkZDNmNWU1ZWE2MDliZjY3MDhmOWVWYWx1ZWA=")

现在这实际上取决于您如何编码数据，对 cbor、protobuf 等使用反序列化。
