如何通过使用Python的加密的binance API获取所有价格历史？

import requests
import json
import hmac
import hashlib
import time

api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECRET'

def generate_signature(data):
    query_string = '&'.join(["{}={}".format(d, data[d]) for d in data])
    return hmac.new(api_secret.encode('utf-8'), query_string.encode('utf-8'), hashlib.sha256).hexdigest()

def get_price_history(symbol, interval, limit):
    base_url = 'https://api.binance.com'
    endpoint = '/api/v3/klines'
    params = {
        'symbol': symbol,
        'interval': interval,
        'limit': limit
    }
    headers = {
        'X-MBX-APIKEY': api_key
    }
    params['timestamp'] = int(time.time() * 1000)
    params['signature'] = generate_signature(params)
    response = requests.get(base_url + endpoint, params=params, headers=headers)
    return json.loads(response.text)

symbol = 'BTCUSDT'
interval = '1d'
limit = 1000

price_history = get_price_history(symbol, interval, limit)
for price in price_history:
    print(price)
