轉換SQL表中的數據JSON

-1

我使用在服務器端的燒瓶，我有以下API：轉換SQL表中的數據JSON

class DateTimeEncoder(json.JSONEncoder): 
    def default(self, o): 
     if isinstance(o, datetime): 
      return o.isoformat() 

     return json.JSONEncoder.default(self, o) 


@app.route('/getTransaction', methods=['GET','POST']) 
def getTransaction(): 

uid = request.form["uid"] 
db = my.connect("somehost.com","someuser","somepwd","someDB") 
cur = db.cursor() 

cur.execute("select * from Transactions where uid='%s'" %(uid)) 

json_string = json.dumps(cur.fetchall(),cls=DateTimeEncoder) 

db.close() 
return json.dumps(json_string)

在此之後，我得到的反應是：

http://sairav.pythonanywhere.com/getTransaction

有沒有一種方法，我可以用鍵（例如名稱，描述，數量，類型，ID，在響應中可以看到的值的時間）以json格式轉換此數據

需要的格式JSON數組：

{"data":[ 
    {"Name":"John", "desc":"Doe","amount":"123.0","type":"credit","uid":"213","time":"12-11-2016 12:23:22"}, 
    {"Name":"John2", "desc":"Doe","amount":"1234.0","type":"credit","uid":"213","time":"12-11-2016 12:23:22"}, 
    {"Name":"John3", "desc":"Doe","amount":"1235.0","type":"credit","uid":"213","time":"12-11-2016 12:23:22"}, 
]}

默認光標是一個行光標即它發出'[ 「約翰」，「DOE」，「123.0」，「信用」]'。您可以創建一個'dictcursor'，它將以字典形式發出行。否則，您可以像訪問[this so answer]（http://stackoverflow.com/a/5058950/1520594）一樣訪問'cursor.description'，並用字段名稱壓縮該行。一旦你有了，你可以繼續使用json.dumps – algrebe

找到真正helpul answer這裏由此能夠徹底解決我的目的，它集我的表列名在JSON數組JSON對象的鍵。感謝algrebe的鏈接。

我與必需的JSON輸出運行的代碼是：

@app.route('/getTransaction', methods=['GET','POST']) 
    def getTransaction(): 

    uid = request.form["uid"] 
    db = my.connect("somehost.com","someuser","somepwd","someDB") 
    cur = db.cursor() 

    cur.execute("select * from Transactions where uid='%s'" %(uid)) 


    **columns = cur.description 
    result = [{columns[index][0]:column for index, column in enumerate(value)} for value in cur.fetchall()]** 


    db.close() 

    **return json.dumps(result,cls=DateTimeEncoder)**
