按照以下代码片段，您可以执行以下操作：
from flask.json import JSonEnprerfrom datetime import dateclass CustomJSonEnprer(JSONEnprer): def default(self, obj): try: if isinstance(obj, date): return obj.isoformat() iterable = iter(obj) except TypeError: pass else: return list(iterable) return JSONEnprer.default(self, obj)app = Flask(__name__)app.json_enprer = CustomJSONEnprer
路线：
import datetime as dt@app.route('/', methods=['GET'])def index(): now = dt.datetime.now() return jsonify({'now': now})
