我无法使用python

Question

我似乎无法使用JSON从网站API获取最后记录的价格。我试图找到错误，但对我来说似乎还可以。代码在python中 这是我必须获取的网址：https://api.independentreserve.com/Public/GetMarketSummary?primaryCurrencyCode=xbt&secondaryCurrencyCode=aud

Python 3.7

import requests


URL = "https://api.independentreserve.com/Public/GetMarketSummary?"

CurrencyCode = "xbt"
SecondaryCode = "aud"
PARAMS = {'primaryCurrencyCode': CurrencyCode, '&secondaryCurrencyCode': SecondaryCode}
r = requests.get(url=URL, params=PARAMS)

data = r.json()


lastprice = data['LastPrice']


print("Last Price:%s" % lastprice)

Answer 1

这是固定代码

import requests


URL = "https://api.independentreserve.com/Public/GetMarketSummary?"

CurrencyCode = "xbt"
SecondaryCode = "aud"
PARAMS = {'primaryCurrencyCode': CurrencyCode, 'SecondaryCurrencyCode': SecondaryCode}
r = requests.get(url=URL, params=PARAMS)

data = r.json()


lastprice = data['LastPrice']


print("Last Price:%s" % lastprice)

问题出在PARAMS字典中。您需要将"&secondaryCurrencyCode"更改为"SecondaryCurrencyCode"。

如果您已打印data字典，则会看到以下内容：

{'Message': 'Secondary Currency Code is required'}

Answer 2

删除&中的"&secondaryCurrencyCode"将解决此问题。

下面的固定代码：

import requests

URL = "https://api.independentreserve.com/Public/GetMarketSummary?"

CurrencyCode = "xbt"
SecondaryCode = "aud"
PARAMS = {'primaryCurrencyCode': CurrencyCode, 'secondaryCurrencyCode': SecondaryCode}
r = requests.get(url=URL, params=PARAMS)

data = r.json()


lastprice = data['LastPrice']

print("Last Price:%s" % lastprice)

Answer 3

API期望secondaryCurrencyCode不能&secondaryCurrencyCode。

使用参数时不需要签名。
