搭建微信公众号后台（二）

一、升级python版本

1. 检测python版本号
   python --version
   一开始python版本号整不到，不是说centos自带python2吗，没事，下面这条命令助你重新做人
   • 下载
     wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0a1.tar.xz
   • 解压缩
     tar xvf Python-3.6.0a1.tar.xz
2. 执行命令
   • 进入目录
     cd /Python-3.6.0a1
   • 执行
     ./configure
   • 若出现异常，则执行
     sudu yum install gcc-c++
3. 执行命令
   make && make install
   执行成功，但缺少pip，问题不大
4. 查看版本
   python3 --version
   成功

• 升级pip版本
  - 安装openssl-devel包
  yum install openssl-devel -y
  如果不行，尝试下这个方法，传送门：https://blog.csdn.net/m0_38016951/article/details/81195377
  - 升级pip3
  pip3 install --upgrade pip
  - 安装Web.py框架
  pip3 install web.py==0.40.dev0
  - 安装WinSCP，实现代码传输，当然，你用vim来写也是可以的
  传送门：WinSCP
  可能会很慢，博主决定xx上网一波，也可以自行百度

二、上传代码

1. 新建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()

2. 新建handle.py

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

import hashlib
import web
import receive
import time
import os

class Handle(object):

    def __init__(self):
        self.app_root = os.path.dirname(__file__)
        self.templates_root = os.path.join(self.app_root, 'templates')
        self.render = web.template.render(self.templates_root)

    def GET(self):
        try:
            data = web.input()
            if len(data) == 0:
                return "hello, this is handle view"
            signature = data.signature
            timestamp = data.timestamp
            nonce = data.nonce
            echostr = data.echostr
            token = "此处内容与公众号基本配置里Token字段取值保持一致"

            list = [token, timestamp, nonce]
            list.sort()
            s = list[0] + list[1] + list[2]
            hashcode = hashlib.sha1(s.encode('utf-8')).hexdigest()
            print( "handle/GET func: hashcode, signature: ", hashcode, signature)
            if hashcode == signature:
                return echostr
            else:
                return echostr
        except (Exception) as Argument:
            return Argument

    def POST(self):
        try:
            webData = web.data()
            print("Handle Post webdata is:\n", webData)
            #打印消息体日志
            recMsg = receive.parse_xml(webData)

            if isinstance(recMsg, receive.Msg) and recMsg.MsgType == 'text':
                toUser = recMsg.FromUserName
                fromUser = recMsg.ToUserName
                content = "欢迎关注云图说！" + str(recMsg.Content)
                print('Reply message info:\n')
                print('toUser =', toUser)
                print('fromUser = ', fromUser)
                print('content = ', content)
                return self.render.reply_text(toUser, fromUser, int(time.time()), content)
            else:
                print("不支持的消息类型：",recMsg.MsgType)
                return "success"
        except (Exception) as Argment:
            return Argment

3. 新建receive.py

# -*- coding: utf-8 -*-
# filename: receive.py
import xml.etree.ElementTree as ET

def parse_xml(web_data):
    if len(web_data) == 0:
        return None
    xmlData = ET.fromstring(web_data)
    msg_type = xmlData.find('MsgType').text
    if msg_type == 'text':
        return TextMsg(xmlData)
    elif msg_type == 'image':
        return ImageMsg(xmlData)
    elif msg_type == 'location':
        return LocationMsg(xmlData)
    elif msg_type == 'event':
        return EventMsg(xmlData)

class Event(object):
    def __init__(self, xmlData):
        self.ToUserName = xmlData.find('ToUserName').text
        self.FromUserName = xmlData.find('FromUserName').text
        self.CreateTime = xmlData.find('CreateTime').text
        self.MsgType = xmlData.find('MsgType').text
        self.Eventkey = xmlData.find('EventKey').text

class Msg(object):
    def __init__(self, xmlData):
        self.ToUserName = xmlData.find('ToUserName').text
        self.FromUserName = xmlData.find('FromUserName').text
        self.CreateTime = xmlData.find('CreateTime').text
        self.MsgType = xmlData.find('MsgType').text
        self.MsgId = xmlData.find('MsgId').text

class TextMsg(Msg):
    def __init__(self, xmlData):
        Msg.__init__(self, xmlData)
        self.Content = xmlData.find('Content').text

class ImageMsg(Msg):
    def __init__(self, xmlData):
        Msg.__init__(self, xmlData)
        self.PicUrl = xmlData.find('PicUrl').text
        self.MediaId = xmlData.find('MediaId').text

class LocationMsg(Msg):
    def __init__(self, xmlData):
        Msg.__init__(self, xmlData)
        self.Location_X = xmlData.find('Location_X').text
        self.Location_Y = xmlData.find('Location_Y').text

class EventMsg(Msg):
    def __init__(self, xmlData):
        Event.__init__(self, xmlData)
        self.Event = xmlData.find('Event').text

4. 新建templates文件夹,在文件夹下新建reply_text.xml

$def with (toUser,fromUser,createTime,content)
<xml>
<ToUserName><![CDATA[$toUser]]></ToUserName>
<FromUserName><![CDATA[$fromUser]]></FromUserName>
<CreateTime>$createTime</CreateTime>
<MsgType><![CDATA[text]]></MsgType>
<Content><![CDATA[$content]]></Content>
</xml>

5. 用winscp上传

三、启动服务

python3 main.py 80
