如何将 api.Response 转换为 python 中的数据框或 json？

Question

我有这样的数据，我想将其转换为数据框。

t = cmc.globalmetrics_quotes_latest()

(Cmc 是 coinmarketcap api)

type(t)=
coinmarketcapapi.response

"""

我试过了：

1)

w=pd.DataFrame.from_dict(pd.json_normalize(t), orient='columns')

TypeError: 'Response' 对象不可迭代

1. crypto_map = pd.DataFrame(t)

ValueError: DataFrame 构造函数未正确调用！

t.json()

ValueError: name 'load' 没有定义

我想在数据中加载一个变量，但它给了我这个错误：

t['active_exchanges']

TypeError: 'Response' 对象不可下标

过去几天我一直在为此苦苦挣扎，但找不到解决方法。

Answer 1

使用t.data 提取您的数据响应

来自documentation：

如果调用成功，所有端点都会以 JSON 格式返回数据，并在 data 下显示您的查询结果。

因此，您可以像这样创建数据框：

df = pd.DataFrame(t.data)
