TDAmeritradeAPI异步io多个行情字符串问题

我们可以使用asyncio.ensure_future作为异步实例。将不同的行情字符串存储在一个列表中，然后使用asyncio.gather同时获取所有行情，并等待它们返回。以下是代码示例：

import asyncio
import json
import aiohttp

API_KEY = 'your_api_key_here'
API_URL = 'https://api.tdameritrade.com/v1/marketdata/quotes'

# Create list of symbols to retrieve quotes for
symbols = ['AAPL', 'GOOG', 'AMZN', 'TSLA']

# Create list to store returned data
data = []

async def get_quote(symbol):
    params = {
        'apikey': API_KEY,
        'symbol': symbol
    }

    async with aiohttp.ClientSession() as session:
        async with session.get(API_URL, params=params) as resp:
            result = await resp.text()
            data.append(json.loads(result))

# Start coroutine for each symbol    
tasks = [asyncio.ensure_future(get_quote(symbol)) for symbol in symbols]

# Wait for all coroutines to complete
loop = asyncio.get_event_loop()
loop.run_until_complete(asyncio.gather(*tasks))

# Print results
print(json.dumps(data, indent=4))

注意：此代码中需要安装aiohttp库。
