个人公众号服务端开发Demo

Posted 2021-01-20 hughzm

公众号出来很久了，也可以个人申请。知道公众号的服务端开发其实很简单，接口调用封装，数据存取，不外如是。

人一旦懒了，真的是 “无可救药” 了。。。现简单描述晚到的公众号HelloWorld

• 思路

  公众号里面简单的文章展示，静态博客展示这种好像没啥特别的，就跳过了。

  在聊天框输入参数， 传到云服务器处理，然后请求个三方API获取信息，封装返回。嗯，这就算个基本的Demo了

•  准备

  1， 得申请个公众号，个人的，免费

  2， 最好买一台云服务器，双十一的阿里云最低100￥/Year，heihei

•   Let‘s go 

  按照 微信的公众号对接的文档来就可以了，直接贴代码

  main.py

# -*- coding: utf-8 -*-
# filename: main.py
import web
from handle import Handle

urls = (
    ‘/wx‘, ‘Handle‘,
)

if __name__ == ‘__main__‘:
    app = web.application(urls, globals())
    app.run()

 handle.py

# -*- coding: utf-8 -*-
# filename: handle.py

LOG_FORMAT = "%(asctime)s - %(levelname)s - %(message)s"
logging.basicConfig(filename=‘root.log‘, level=logging.INFO, format=LOG_FORMAT)

# 调用查询号码省份运营商的API，简单暴力正则匹配结果返回
def getCurrentPhoneNumInfo(num):
    logging.info("getCurrentPhoneNumInfo[%s]", num)
    try:
        if re.match("^1[3|5|7|8]d{9}$", num) == None:

        else:

            m = re.search("carrier:‘(.*)‘.*", r.text, re.M)
            result = m.group(1)
            logging.info("result=%s" , result) 
            return result.encode("UTF-8") # python2的转码问题总是会坑到一批新人
    except Exception as e:
