python - 使用 Python（最好是请求）从 Binance API 获取烛台/Kline 数据以获取 JSON 数据

Question

我正在开发一个从 Binance API 获取烛台数据的电报机器人。我无法获得 JSON 数据作为响应。以下代码是我尝试过的。

 import requests 

 import json

 import urllib.request

`url = "https://api.binance.com/api/v1/klines"

response = requests.request("GET", url)
print(response.text)`

期望的输出：

[ [ 1499040000000, // Open time "0.01634790", // Open "0.80000000", // High "0.01575800", // Low "0.01577100", // Close "148976.11427815", // Volume 1499644799999, // Close time "2434.19055334", // Quote asset volume 308, // Number of trades "1756.87402397", // Taker buy base asset volume "28.46694368", // Taker buy quote asset volume "17928899.62484339" // Ignore ] ]

问题编辑：

我得到的输出是：

 `{"code":-1102,"msg":"Mandatory parameter 'symbol' was not sent, was empty/null, or malformed."}'

Answer 1

您缺少强制参数符号和间隔，查询应该是这样的：

https://api.binance.com/api/v3/klines?symbol=BTCUSDT&interval=1h

您只需要导入请求：

import requests

market = 'BTCUSDT'
tick_interval = '1h'

url = 'https://api.binance.com/api/v3/klines?symbol='+market+'&interval='+tick_interval
data = requests.get(url).json()

print(data)

requests python 包有一个params,json参数，所以你不需要导入任何你正在导入的包。

import requests

url = 'https://api.binance.com/api/v3/klines'
params = {
  'symbol': 'BTCUSDT',
  'interval': '1h'
}
response = requests.get(url, params=params)
print(response.json())
