Python：Flask使用jsonify格式化时间

# -*- coding: utf-8 -*-
from datetime import datetime, date

from flask.json import JSONEncoder


class CustomJSONEncoder(JSONEncoder):
    def default(self, obj):
        if isinstance(obj, datetime):
            return obj.strftime('%Y-%m-%d %H:%M:%S')
        elif isinstance(obj, date):
            return obj.strftime('%Y-%m-%d')
        else:
            return JSONEncoder.default(self, obj)

from datetime import datetime

from flask import Flask, jsonify

app = Flask(__name__)

# 替换默认的json编码器
app.json_encoder = CustomJSONEncoder

@app.route('/test')
def test_world():
    time = datetime.now()
    return jsonify({ 
   'time': time})

{ 
   
  "time": "2020-09-17 16:31:55"
}
