首先推荐 tornado,Tornado 是一个 Python web 框架和异步网络库,最初在 FriendFeed 开发。通过使用无阻塞网络 I/O,Tornado 可以扩展到数万个开放连接,使其成为长轮询、WebSocket 和其他需要与每个用户建立长时间连接的应用程序的理想选择。简易而且本地 win10 能够跑起来。
import tornado.ioloop
import tornado.web
import json
class MainHandler(tornado.web.RequestHandler):
def get(self):
"""get请求"""
a = self.get_argument('a')
b = self.get_argument('b')
c = int(a) + int(b)
self.write("c=" + str(c))
def post(self):
'''post请求'''
body = self.request.body
body_decode = body.decode()
body_json = json.loads(body_decode)
a = body_json.get("a")
b = body_json.get("b")
c = int(a) + int(b)
self.write("c=" + str(c))
application = tornado.web.Application([(r"/add", MainHandler), ])
if __name__ == "__main__":
application.listen(8868)
tornado.ioloop.IOLoop.instance().start()
3. GET 接口访问:http://127.0.0.1:8868/add?a=1&b=2
浏览器请求结果:
4. POST 接口请求 http://127.0.0.1:8868/add
也可以使用 Django 或者 Tornado

结果为:
