如何使用telegram bot以JSON格式发送带有信息的消息

Question

我正试图使用telegram bot将此信息作为消息发送。但是，当我尝试发送消息时，我遇到了一个错误：card=f'｛hbold("ExchangeName:"｝｛(item.get("exchange_name"((｝\n'
AttributeError:"str"对象没有属性"get"。我该怎么修？

"name_of_coin": "Bitcoin",
"marketPairs": [
{
"exchange_name": "Binance",
"market_url": "https://www.binance.com/en/trade/BTC_USDT",
"price": 49516.15001013148,
"last_update": "2021-12-05T12:32:54.000Z",
"exchange_id": 270
},
{
"exchange_name": "Coinbase Exchange",
"market_url": "https://pro.coinbase.com/trade/BTC-USD",
"price": 49610.79,
"last_update": "2021-12-05T12:32:55.000Z",
"exchange_id": 89
},
{
"exchange_name": "Bitfinex",
"market_url": "https://www.bitfinex.com/t/BTC:USD",
"price": 49586.15351025,
"last_update": "2021-12-05T12:32:53.000Z",
"exchange_id": 37
},
{
"exchange_name": "FTX",
"market_url": "https://ftx.com/trade/BTC/USDT",
"price": 49508.56563407031,
"last_update": "2021-12-05T12:32:53.000Z",
"exchange_id": 524
}
]

我的代码：

with open(file_path) as file:
data = json.load(file)
for item in data:
card = f'{hbold("ExchangeName: ")}{(item.get("exchange_name"))}n' 
f'{hbold("MarketUrl: ")}{(item.get("market_url"))}n' 
f'{hbold("Price: ")}{(item.get("price"))}n' 
f'{hbold("LastUpdated: ")}{(item.get("last_update"))}n' 
f'{hbold("ExchangeId: ")}{(item.get("exchange_id"))}n' 
await message.answer(card)

Answer 1

让我们做

with open(file_path) as file:
data = json.load(file)

我们需要从名为"marketPears"的字典密钥中获取值，然后我们需要写：

for item in data['marketPairs']:

现在我们需要正确地使用字符串格式以使其正确。请不要在字符串结束前加引号。看看这个：

card = f'ExchangeName: {item["exchange_name"]}n
MarketURL: {item["market_url"]} etc.'

我使用\n \ without qoutes首先用于输出中的新行(符号(，然后用于代码中的换行(符号(那么，您可以使用aiogramlib中的send_message。因为应答在用户的消息后使用，但"send_message"不等待用户的响应。

await bot.send_message(user_id, card)
