python3.6写一个http接口服务，给别人调用1

# -*- coding:utf-8 -*-

import tornado.ioloop
import tornado.web


class MainHandler(tornado.web.RequestHandler):
    def get(self):
        """get请求"""
        a = self.get_argument('a')
        b = self.get_argument('b')
        # print(a)
        # print(type(a))
        # print(b)
        # print(type(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()

运行然后访问  http://127.0.0.1:8868/add?a=1&b=2  就可以了

得到的结果是:

推荐使用Django或者Tornado 

2.调用一个函数的

from concurrent.futures import ThreadPoolExecutor
from tornado.concurrent import run_on_executor
import tornado.httpserver
import tornado.ioloop
import tornado.options
import tornado.web
import tornado.gen
import json
import traceback

def add(a,b):
    c = int(a) + int(b)
    return str(c)


class MainHandler(tornado.web.RequestHandler):
    executor = ThreadPoolExecutor(32)
    @tornado.gen.coroutine
    def get(self):
        '''get接口'''
        htmlStr = '''
                    
                    
                    
                    
                    

                    a:

                    

                    b:

                    

                    
                    
                    
 
                '''
        self.write(htmlStr)

    @tornado.web.asynchronous
    @tornado.gen.coroutine
    def post(self):
        '''post接口， 获取参数'''
        a = self.get_argument("a", None)
        b = self.get_argument("b", None)
        yield self.coreOperation(a, b)

    @run_on_executor
    def coreOperation(self, a, b):
        '''主函数'''
        try:
            if  a != '' and b != '':
                result = add(a, b)  #可调用其他接口
                if result:
                    result = json.dumps({'code': 200, 'result': result, })
                else:
                    result = json.dumps({'code': 210, 'result': 'no result',})

            else:
                result = json.dumps({'code': 211, 'result': 'wrong input a or b', })
            self.write(result)
        except Exception:
            print ('traceback.format_exc():\n%s' % traceback.format_exc())
            result = json.dumps({'code': 503,'result': str(a)+'+'+str(b)})
            self.write(result)


if __name__ == "__main__":

    tornado.options.parse_command_line()
    app = tornado.web.Application(handlers=[(r'/post', MainHandler)], autoreload=False, debug=False)
    http_server = tornado.httpserver.HTTPServer(app)
    http_server.listen(8832)
    tornado.ioloop.IOLoop.instance().start()

结果为：

1.

2.

找了好多东西，都不靠普

老版本的： https://www.cnblogs.com/dpf-learn/p/8028029.html

这个不错，但还是不行：https://blog.csdn.net/linux_hacher/article/details/78753805

看到这里，原来改版了：https://docs.python.org/3/library/http.server.html#http.server.SimpleHTTPRequestHandler

不过把BaseHTTPServer、CGIHTTPServer等，在便3.4.2后都集成到http.server里边去了
