import time
import requests  # pip3 install requests
import json

# Extra headers
test_headers = {
    'Content-Type': 'application/json'
}

将如下JSON进行url的encode，复制到http的查询字符串的query字段里
{"trace" : "python_http_test1","data" : {"code" : "BTCUSD","kline_type" : 1,"kline_timestamp_end" : 0,"query_kline_num" : 1,"adjust_type": 0}}
'''

# Modify the URL to request BTCUSD (Bitcoin to USD) real-time price
test_url = 'https://quote.aatest.online/quote-b-api/kline?token=3662a972-1a5d-4bb1-88b4-66ca0c402a03-1688712831841&query=%7B%22trace%22%20%3A%20%22python_http_test1%22%2C%22data%22%20%3A%20%7B%22code%22%20%3A%20%22BTCUSD%22%2C%22kline_type%22%20%3A%201%2C%22kline_timestamp_end%22%20%3A%200%2C%22query_kline_num%22%20%3A%201%2C%22adjust_type%22%3A%200%7D%7D'

resp = requests.get(url=test_url, headers=test_headers)

# Decoded text returned by the request
text = resp.text
print(text)

也可以使用Websocket订阅BTC的实时报价：

import websocket  # pip install websocket-client
