Question

我正在监视来自Blockchain.info API的未确认交易。这是我的Python代码：

import json
from websocket import create_connection

ws = create_connection("wss://ws.blockchain.info/inv")
ws.send("""{"op":"unconfirmed_sub"}""")
while True:
    tx = ws.recv()
    data_decoded=json.loads(tx)
    hash=data_decoded['x']['hash']
    addr=data_decoded['x']['out'][0]['addr']
    print(hash)
    print(addr)

这正确连接并显示每个事务，如下所示：

    "x": {
        "lock_time": 0,

            }
        ]
    }
}

但是现在，它仅显示['x']['hash']和第一个['x']['out']['addr']中的数据，而不是在示例中有多个像这样的情况下打印所有addr。

如何获取所有['x']['out']['addr']的打印内容？

Answer 1

exports.handler = async (event) => {
  context.callbackWaitsForEmptyEventLoop = false
  const db = await connect()
  await db.write(data)
  return { ok: true }
}

编辑：因此，我在下面的评论之后对此进行了测试，并且不需要json.loads。这有效：

hash=your_json['x']['hash']
addr=your_json['x']['out]['addr']

此外，要访问嵌套列表中的所有地址，您将需要遍历它们：

print(x['x']['hash'])

在Websockets中使用Python？
