我如何将api中的数据存储在数据框内？

Question

你好，我有这些数据：

{"success":true,"message":"","result":    
{"O":0.00019513,"H":0.00019527,"L":0.00019513,"C":0.00019527,"V":367.75179374,"T":"2019-04-29T21:00:00","BV":0.0717955325124862}, 
{"O":0.00019513,"H":0.00019583,"L":0.00019513,"C":0.00019583,"V":5389.26298513,"T":"2019-04-29T21:30:00","BV":1.0526250707404440},
{"O":0.00019474,"H":0.00019583,"L":0.00019474,"C":0.00019583,"V":2199.01385578,"T":"2019-04-29T22:00:00","BV":0.4306096361379076},
{"O":0.00019621,"H":0.00019621,"L":0.00019621,"C":0.00019621,"V":1747.38721102,"T":"2019-04-29T22:30:00","BV":0.3428548446742342},
{"O":0.00019627,"H":0.00019627,"L":0.00019452,"C":0.00019452,"V":452.75087850,"T":"2019-04-29T23:00:00","BV":0.0880756649231950}],"explanation":null}

我想将这些数据存储在一个数据框中。我试过了（变量URL包含上面的数据）：

reponse = urlopen(url)
data = json.load(reponse)
df = pd.DataFrame(data)

我想有7列，例如：

df['0'], df['H'], df['L'], df['C'], df['V'], df['T'], df['BV']

但是我对此没有任何想法...

能帮我吗？

非常感谢您！
