如何使用jsonrpc near协议中的call_function来获取实际数字？

Question

下面的查询在near协议中使用jsonrpc中的call_function

http post https://rpc.testnet.near.org jsonrpc=2.0 id=test method=query   params:='{
    "request_type": "call_function",
    "finality": "final",
    "account_id": "dev-1591261827342",
    "method_name": "get_total_supply",
    "args_base64": "e30="
  }'

给出以下结果：

{
    "id": "test",
    "jsonrpc": "2.0",
    "result": {
        "block_hash": "FrKNvsEbqPsdT1ijLkUBNoX3SnUQbTCXjoPj7yC2WW5i",
        "block_height": 9616038,
        "logs": [],
        "result": [
            34,
            49,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            34
        ]
    }
}

如何将结果转换为实际的数字'1000000000000000'？

Answer 1

"result": [
            34,
            49,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            48,
            34
        ]

是一个字节数组。默认情况下，NEAR SDK对输入和输出使用JSON编码，但不限于此，所以如果您转换它，就会得到"1000000000000000"。下面是用于转换它的Python代码片段：

>>> result = [34, 49, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 48, 34]
>>> ''.join(chr(x) for x in result)
'"1000000000000000"'
