具有特定格式的 Json 到 Pandas DataFrame

Question

我需要在 Pandas DataFrame 中以某種格式加載 Json 文件的內容，以便我可以運行 pandassql 來轉換數據。

        }]

}

解析 json 后，我想獲得如下所述的 DataFrame 對象。

問題名稱| 主要位置| 問題狀態| 找到日期| 項目版本 ID| 完整文件名

空取消引用| AdminWSHelper.java| xxx| xxx| xxx | 12345| yyyy|...helper/AdminWSHelper.java

空取消引用| AdminWSHelper.java|xxx| xxx| xxx | 12345| yyyy |...helper/AdminWSHelper.java

我試過這樣：

dataSource = FortifyClient.readFileContent('sample.json')    
print('json data : '+dataSource)
df = pd.io.json.json_normalize(dataSource) 

我得到的錯誤：

Traceback (most recent call last):
  File "C:\Java_Projects\FortiFyReportingEngine\FortifyClient.py", line 67, in <module>
    df = pd.io.json.json_normalize(dataSource) 
  File "C:\Python\Python37-32\lib\site-packages\pandas\io\json\_normalize.py", line 258, in json_normalize
    if any([isinstance(x, dict) for x in y.values()] for y in data):
  File "C:\Python\Python37-32\lib\site-packages\pandas\io\json\_normalize.py", line 258, in <genexpr>
    if any([isinstance(x, dict) for x in y.values()] for y in data):
AttributeError: 'str' object has no attribute 'values'

任何人都可以幫助我實現這一目標嗎？

Answer 1

這應該有效：

import json

with open('sample.json') as f:
    d = json.loads(f)

df = pd.DataFrame(d['data'])
