2.获取access_token

https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET
把APPID和APPSECRET换成图上的,即可获取Access_token
3.创建自定义菜单
打开调试接口, body部分填写
{
"menu": {
"button": [
{
"type": "click",
"name": "查询设备",
"key": "V1001_TODAY_MUSIC",
"sub_button": [ ]
},
{
"name": "菜单",
"sub_button": [
{
"type": "click",
"name": "第一路:开",
"key": "v1_on",
"sub_button": [ ]
},
{
"type": "click",
"name": "第一路:关",
"key": "v1_off",
"sub_button": [ ]
},
{
"type": "click",
"name": "第二路-开",
"key": "v2_on",
"sub_button": [ ]
},
{
"type": "click",
"name": "第一路-关",
"key": "v2_off",
"sub_button": [ ]
}
]
}
]
}
}

4.回到树莓派上
4.1 安装webpy
pip install web.py
4.2 创建main.py文件
sudo nano mainpy
#!/usr/local/bin/python
#coding=utf-8
import web
from handle import Handle
urls = (
'/wx', 'Handle',
)
if __name__ == '__main__':
app = web.application(urls, globals())
app.run()
4.3 创建receive.py
sudo nano 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 == 'event':
return gpioMsg(xmlData)
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
class gpioMsg(Msg):
def __init__(self, xmlData):
Msg.__init__(self, xmlData)
self.EventKey = xmlData.find('EventKey').text.encode("utf-8")
class TextMsg(Msg):
def __init__(self, xmlData):
Msg.__init__(self, xmlData)
self.MsgId = xmlData.find('MsgId').text
self.Content = xmlData.find('Content').text.encode("utf-8")
class ImageMsg(Msg):
def __init__(self, xmlData):
Msg.__init__(self, xmlData)
self.MsgId = xmlData.find('MsgId').text
self.PicUrl = xmlData.find('PicUrl').text
self.MediaId = xmlData.find('MediaId').text
4.4 创建 reply.py
sudo nano reply.py
# -*- coding: utf-8 -*-
# filename: reply.py
import time
class Msg(object):
def __init__(self):
pass
def send(self):
return "success"
class TextMsg(Msg):
def __init__(self, toUserName, fromUserName, content):
self.__dict = dict()
self.__dict['ToUserName'] = toUserName
self.__dict['FromUserName'] = fromUserName
self.__dict['CreateTime'] = int(time.time())
self.__dict['Content'] = content
def send(self):
XmlForm = """
<xml>
<ToUserName><![CDATA[{ToUserName}]]></ToUserName>
<FromUserName><![CDATA[{FromUserName}]]></FromUserName>
<CreateTime>{CreateTime}</CreateTime>
<MsgType><![CDATA[text]]></MsgType>

</xml>
"""
return XmlForm.format(**self.__dict)
class ImageMsg(Msg):
def __init__(self, toUserName, fromUserName, mediaId):
self.__dict = dict()
self.__dict['ToUserName'] = toUserName
self.__dict['FromUserName'] = fromUserName
self.__dict['CreateTime'] = int(time.time())
self.__dict['MediaId'] = mediaId
def send(self):
XmlForm = """
<xml>
<ToUserName><![CDATA[{ToUserName}]]></ToUserName>
<FromUserName><![CDATA[{FromUserName}]]></FromUserName>
<CreateTime>{CreateTime}</CreateTime>
<MsgType><![CDATA[image]]></MsgType>
<Image>
<MediaId><![CDATA[{MediaId}]]></MediaId>
</Image>
</xml>
"""
return XmlForm.format(**self.__dict)
4.5 创建handel.py
sudo nano handle.py
注意token的填写
