Question

我是python中的websockets和json的新手。我只想知道如何像这样将json数据转换为字符串

{'data': {'id': 26, 'level': 2, 'message': 'Something was Detected'}}

进入

"26"
"2"
"Something was Detected"

或仅将其制成字符串的任何格式。

我正在从本地网络套接字接收我的json数据，此处是代码。

async with websockets.connect(url) as websocket:
        data = dict(topic='device:10', event="phx_join", payload={}, ref=0)
        await websocket.send(json.dumps(data))

        # Json data will be receive here
        message = await websocket.recv()

        # then it will be printed here
        print(message)

        # I need to convert the message into string

asyncio.get_event_loop().run_until_complete(hello('ws://localhost:4000/socket/websocket'))

Answer 1

类似这样的东西：

data = json.loads(message)
list_of_strings = [str(v) for k, v in data['data'].items()]

Answer 2

这是我获得所需输出的方式

async with websockets.connect(url) as websocket:
    data = dict(topic='device:10', event="phx_join", payload={}, ref=0)
    await websocket.send(json.dumps(data))

    # Json data will be receive here
    message = await websocket.recv()

    # then it will be printed here
    print(message)

    # The answer for the question
    message_json = json.loads(message)
    id = message_json['data']['id']
    print(id)
    level = message_json['data']['level']
    print(level)
    mes = message_json['data']['message']
    print(mes)
asyncio.get_event_loop().run_until_complete(hello('ws://localhost:4000/socket/websocket')
