Question

这是我的Json文件

{
    "highest_table": {
        "items": [{
                "key": "Human 1",
                "columns": {
                    "Na$me": "Tom",
                    "Description(ms/2)": "Table Number One on the Top",
                    "A&ge": "24",
                    "Ge_nder": "M"
                }
            },
            {
                "key": "Human 2",
                "columns": {
                    "Na$me": "John",
                    "Description(ms/2)": "Table Number One on the Top",
                    "A&ge": "23",
                    "Ge_nder": "M"
                }
                }
        ]
    }
}

目标是删除列名称中的所有特殊字符（或者，如果方便的话，删除.json文件中的所有特殊字符），并返回.json文件。我最初的想法是将其转换为熊猫，删除列标题中的特殊字符，然后将其转换回.json文件。

这是我到目前为止尝试过的。他们两个都只打印一行。

import json
from pandas.io.json import json_normalize    

data_file = r"C:\characters.json"

with open(data_file) as data_file:    
    data = json.load(data_file)  

df = json_normalize(data)

-

data_file = r"C:\characters.json"

df = pd.read_json(data_file)

如何提取列，删除特殊字符并将其放回.json文件中？

有点问题-您必须为NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(activity); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { mBuilder.setColor(activity.getResources().getColor(R.color.pricify_red)); mBuilder.setSmallIcon(R.drawable.transparent_img); } else { mBuilder.setColor(activity.getResources().getColor(R.color.pricify_red)); mBuilder.setSmallIcon(R.drawable.app_logo); } mBuilder.setContentTitle(title) .setContentText(msg); Intent i = new Intent(); i.setComponent(new ComponentName(currentActivity.this, DesiredActivity.class)); PendingIntent pIntent = PendingIntent.getActivity(activity, 0, i, 0); mBuilder.setContentIntent(pIntent); NotificationManager mNotificationManager = (NotificationManager) activity.getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(mNotificationId, mBuilder.build());提供完整的实现，但这应该可以解决您的问题。

坦率地说，这是丑陋的，但是我还没有找到更通用的方法。这是特定于您的特定JSON的（问题确实需要在API中解决）。

import json


response = """{
    "highest_table": {
        "items": [{
                "key": "Human 1",
                "columns": {
                    "Na$me": "Tom",
                    "Description(ms/2)": "Table Number One on the Top",
                    "A&ge": "24",
                    "Ge_nder": "M"
                }
            },
            {
                "key": "Human 2",
                "columns": {
                    "Na$me": "John",
                    "Description(ms/2)": "Table Number One on the Top",
                    "A&ge": "23",
                    "Ge_nder": "M"
                }
                }
        ]
    }
}"""

def fix_json(resp):

    output = {'highest_table': {'items': []}}
    for item in resp['highest_table']['items']:
        inner_dict = item['columns']
        fixed_values = {'Name': inner_dict['Na$me'],
                        'Description(ms/2)': inner_dict['Description(ms/2)'],
                        'Age': inner_dict['A&ge'],
                        'Gender': inner_dict['Ge_nder']
                        }
        new_inner = {'key': item['key'], 'columns': fixed_values}
        output['highest_table']['items'].append(new_inner)
    return output



response = json.loads(response)
fixed = fix_json(response)
