eth_keys 如何获取字符串 public 键以便我可以将其放入 JSON

Question

我有一个私人的 - public 密钥签名可以正常工作：

print(signature.verify_msg(bytes(transaction_hash.hexdigest().encode('utf-8')), first_wallet['public_key']))

verify_signature: 0xf9671943931afb93e1613eb5d73a77ed961653f70562884709d45ffa774fa7f756b7e8b8a4bd11ffe71448eedddfc10e7dbcd4b069477c7665e6a978347b6e42

True

但是我需要json 序列化 public 密钥以便节点可以进行验证，我已经尝试了很多东西。第一个错误是：

TypeError: Object of type 'PublicKey' is not JSON serializable

然后，如果我用 first_wallet['public_key'].to_hex() 序列化它，当节点使用那个 public 密钥来验证我得到的消息时：

eth_keys.exceptions.ValidationError: Unexpected uncompressed public key length: Expected 64, but got 130 bytes

Answer 1

你能不能把它序列化成字节，它可能正在读取十六进制的长度。我在下面有几个示例是 json 可序列化的，服务器可能除外。在不知道你在另一端连接哪个库的情况下，我决定展示几个例子。
