时间转换

Pendulum

class JSONEncoderTime(JSONEncoder):
    def default(self, obj):
        if isinstance(obj, LocalProxy):
            obj = obj._get_current_object()
        if isinstance(obj, datetime):
            objs = obj.astimezone(pytz.utc)
            return objs.strftime('%Y-%m-%dT%H:%M:%SZ')
        return JSONEncoder.default(self, obj)

在 Flask 中使用它的必要步骤见下:

from flask import Flask

app = Flask(__name__)
 app.json_encoder = JSONEncoderTime
