如何提取已部署的智能合约的存储数据?我正在尝试从Tezos基金会中读取"免费Ledger Nano S"合同KT1BRudFZEXLYANgmZTka1xCDN5nWTMWY7SZ中的存储数据,因为我对它的工作方式感兴趣.合同代码非常简单.例如,TzScan不显示存储数据,它显示的只是Unit,在这种情况下没有用.旧问题的解决方案如何获取智能合约存储数据?不再起作用.

How do I extract the storage data of a deployed smart contract? I am trying to read the storage data from the "free Ledger Nano S" contract KT1BRudFZEXLYANgmZTka1xCDN5nWTMWY7SZ from the Tezos Foundation, because I am interested in how it works. The contract code is pretty straight forward. TzScan for example doesn't show the storage data, all it shows is Unit which in this case is not useful. The solution from an old question How to get smart-contract storage data? doesn't work anymore.

smart-contracts contract storage

让我们找到Arronax合同并查看其代码...

 storage unit;
code { CDR ;
       NIL operation ;
       AMOUNT ;
       PUSH mutez 0 ;
       { COMPARE ; EQ ; IF {} { SOURCE ; CONTRACT unit ; { IF_NONE { { UNIT ; FAILWITH } } {} } ; AMOUNT ; UNIT ; TRANSFER_TOKENS ; CONS } } ;
       PAIR }

..您将看到合同中没有有效地存储任何内容,这就是为什么您只获得Unit的原因.

Let's find the contract on Arronax and look at its code...

storage unit;
code { CDR ;
       NIL operation ;
       AMOUNT ;
       PUSH mutez 0 ;
       { COMPARE ; EQ ; IF {} { SOURCE ; CONTRACT unit ; { IF_NONE { { UNIT ; FAILWITH } } {} } ; AMOUNT ; UNIT ; TRANSFER_TOKENS ; CONS } } ;
       PAIR }

..you will see that nothing is effectively being stored in the contract, which is why you're just getting Unit.

在命令行中

./tezos-client get contract storage for KT1BRudFZEXLYANgmZTka1xCDN5nWTMWY7SZ

您也可以只调用RPC

curl http://localhost:8732/chains/main/blocks/head/context/contracts/KT1BRudFZEXLYANgmZTka1xCDN5nWTMWY7SZ/storage

当然,这是假设您自己运行一个节点.但这就是我想要的.谢谢

This is of course assuming you are running a node by yourself. But this is what I was looking for. Thx
