Question

我用这个：

import requests

url = "https://api.bitfinex.com/v1/pubticker/btcusd"

response = requests.request("GET", url)

print (response.text)

输出结果为：

{"mid":"4432.95","bid":"4432.9","ask":"4433.0","last_price":"4432.9","low":"4276.9","high":"4482.0","volume":"32877.86104158","timestamp":"1506955900.864889"}

我想把最后的价格作为一个浮点数，以便用它进行一些计算......

我无法弄清楚如何做到这一点...... 你能帮我吗？ THX

Answer 1

试试这样：

import requests

url = "https://api.bitfinex.com/v1/pubticker/btcusd"

response = requests.request("GET", url)

data = response.json()
last_price = float(data.get('last_price'))
print(last_price)

Answer 2

响应是一个JSON，因此如果您在响应中调用requests方法，.json()将为您解析它。你只需要这样做：

import requests

resp_json = requests.get("https://api.bitfinex.com/v1/pubticker/btcusd").json()
# resp_json is a native Python dict representing the JSON response content. But since all values are strings in the response, you need to convert them to a float manually.
print(float(resp_json["last_price"]))

使用Python从bitfinex获取数据
