EOS cleos ABI transfer 推送操作

推送操作

根据合约ABI，消息应该是合约。

例如，货币合约的ABI被构造如下。

$ cleos get code -a currency.abi currency
code hash: 9b9db1a7940503a88535517049e64467a6e8f4e9e03af15e9968ec89dd794975
saving abi to currency.abi
$ cat currency.abi
{
  "types": [{
      "newTypeName": "AccountName",
      "type": "Name"
    }
  ],
  "structs": [{
      "name": "transfer",
      "base": "",
      "fields": {
        "from": "AccountName",
        "to": "AccountName",
        "amount": "UInt64"
      }
    },{
      "name": "account",
      "base": "",
      "fields": {
        "account": "Name",
        "balance": "UInt64"
      }
    }
  ],
  "actions": [{
      "action": "transfer",
      "type": "transfer"
    }
  ],
  "tables": [{
      "table": "account",
      "indextype": "i64",
      "keynames": [
        "account"
      ],
      "keytype": [],
      "type": "account"
    }
  ]
}

从上面的abi中，我们可以看到货币合约接受一个叫做transfer的操作，它接受带有from，to和amount字段的消息。

$ ./cleos push message currency transfer '{"from":"currency","to":"tester","amount":50}' -S currency -S tester -p currency@active

            "permission": "active"
          }
        ],
        "data": {
          "from": "currency",
          "to": "tester",
          "quantity": 50
        },
        "hex_data": "00000079b822651d00000000c84267a13200000000000000"
      }
    ],
    "output": [{
        "notify": [{
            "name": "tester",
            "output": {
              "notify": [],
              "sync_transactions": [],
              "async_transactions": []
            }
          }
        ],
        "sync_transactions": [],
        "async_transactions": []
      }
    ]
  }
}
