我在锯齿上开了一笔交易。我可以使用API​​查看交易数据。我的问题是如何解码事务负载。

    }

我要解码有效载荷”："o2RWZXJiY3NldGROYW1leCBlZjlkMThjZGIwYjNkZDNmNWU1ZWE2MDliZjY3MDhmOWVWYWx1ZWA=".
任何人都可以指导。

Answer 1

sawtooth rest-api返回base64编码的数据，首先，您必须解码您的数据，

    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。
