获取 polygonio 数据的示例

以下是使用 polygon.io API 获取数据的示例代码：

import requests

# 设置 API 密钥和基本 URL
api_key = "YOUR_API_KEY"
base_url = "https://api.polygon.io"

# 获取股票历史数据
def get_stock_history(symbol, limit=10):
    endpoint = f"/v2/aggs/ticker/{symbol}/range/1/day/latest?apiKey={api_key}&limit={limit}"
    url = base_url + endpoint
    response = requests.get(url)
    if response.status_code == 200:
        data = response.json()['results']
        for item in data:
            print(item['t'], item['o'], item['h'], item['l'], item['c'])
    else:
        print("Failed to fetch stock history.")

# 获取股票实时报价
def get_stock_quote(symbol):
    endpoint = f"/v1/last/stocks/{symbol}?apiKey={api_key}"
    url = base_url + endpoint
    response = requests.get(url)
    if response.status_code == 200:
        data = response.json()
        print(data['last']['price'])
    else:
        print("Failed to fetch stock quote.")

# 示例用法
get_stock_history("AAPL", limit=5)
get_stock_quote("AAPL")

请确保将 YOUR_API_KEY 替换为您在 polygon.io 网站上获得的 API 密钥
