如果您从您的网址使用pandas 到read_json,它会将所有json 数据保存到一个单元格中(列chart,行result)。
根据您的代码,您必须提取'timestamp','open','high,'low' 和'close' 的字典数据,然后将它们传递给pandas DataFrame:
import pandas as pd
df = pd.read_json('https://query1.finance.yahoo.com/v7/finance/chart/CPN.BK?range=2y&interval=1d&indicators=quote&includeTimestamps=true')
data = df['chart']['result'][0]
result = {'timestamp':data['timestamp'],
'open':data['indicators']['quote'][0]['open'],
'high':data['indicators']['quote'][0]['high'],
'low':data['indicators']['quote'][0]['low'],
'close':data['indicators']['quote'][0]['close']
}
df1 = pd.DataFrame(result, columns==['timestamp','open','high','low','close'])
df1
df1 将是:
timestamp open high low close
0 1442977200 44.50 45.25 44.25 45.00
1 1443063600 44.75 45.75 44.50 45.00
2 1443150000 44.75 45.00 44.25 44.50
3 1443409200 44.25 44.25 43.00 43.00
4 1443495600 42.50 44.50 42.25 44.00
5 1443582000 44.25 44.75 43.50 44.75
6 1443668400 44.50 45.00 44.25 45.00
7 1443754800 45.00 45.00 44.00 44.25
8 1444014000 44.25 44.75 43.75 44.50
...
或者,您可以从 url 加载 json(参考this answer),然后提取字典数据('timestamp','open','high,'low' and 'close'),将其传递给 pandas 以生成结果数据帧。
