## 申请服务器，公众号
博主申请了腾讯云的服务器，还有一篇[腾讯云简单网站设置教程](https://blog.csdn.net/LuckyMon/article/details/89024375)，这里先关掉http服务器 service httpd stop，省得后面占用80端口。公众号能够去微信公众平台申请，这里博主申请了订阅号。

## 搭建服务
这里博主安装了python2.7和 [web.py](http://webpy.org/)，使用了pip进行安装[Python pip 安装与使用](https://www.runoob.com/w3cnote/python-pip-install-usage.html)

第一步肯定可否在服务器运行python，网页端访问，官网提供代码以下：

```
# -*- coding: utf-8 -*-
# filename: main.py
import web

urls = (
    '/wx', 'Handle',
)

class Handle(object):
    def GET(self):
        return "hello, this is handle view"

if __name__ == '__main__':
    app = web.application(urls, globals())
    app.run()
```
在服务器进入放 main.py 的文件夹，命令行输入python main.py 80 ，此步易发生端口被占用状况，需多多注意。命令行显示0.0.0.0 是正常状况，可正常访问  http://服务器IP/wx 。443端口一样能够使用，命令行输入python main.py 443 ，可正常访问  https://服务器IP/wx 。可依照实际状况选择。下图是官网给的访问状况。
## 开发者基本配置（token）
下图是博主配置成功了的，没有打码，固然如今没法访问，博主把80端口改回了http服务。token令博主头疼了很长时间。
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()
```

新增handle.py

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

import hashlib
import web

class Handle(object):
    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 = "hello" #我设置的token

            list = [token, timestamp, nonce]
            list.sort()
            sha1 = hashlib.sha1()
            map(sha1.update, list)
            hashcode = sha1.hexdigest()
            print "handle/GET func: hashcode, signature: ", hashcode, signature
            if hashcode == signature:
                return echostr
            else:
                return ""
        except Exception, Argument:
            return Argument
```
从新启动 python main.py 80 ，成功的话，点击启动按钮

## 简单回复
须要四个python
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

import hashlib
import reply
import receive
import web

class Handle(object):
    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 = "hello" #请按照公众平台官网\基本配置中信息填写

            list = [token, timestamp, nonce]
            list.sort()
            sha1 = hashlib.sha1()
            map(sha1.update, list)
            hashcode = sha1.hexdigest()
            print "handle/GET func: hashcode, signature: ", hashcode, signature
            if hashcode == signature:
                return echostr
            else:
                return ""
        except Exception, Argument:
            return Argument

    def POST(self):
        try:
            webData = web.data()
            print "Handle Post webdata is ", webData#后台打日志
            recMsg = receive.parse_xml(webData)
            if isinstance(recMsg, receive.Msg) and recMsg.MsgType == 'text':
                toUser = recMsg.FromUserName
                fromUser = recMsg.ToUserName
                content = "test"
                replyMsg = reply.TextMsg(toUser, fromUser, content)
                return replyMsg.send()
            else:
                print "暂且不处理"
                return "success"
        except Exception, Argment:
            return Argment

receive.py

```
reply.py

```

所有添加后，从新启动 python main.py 80 。成功向微信公众号发送数据会返回test
