微信菜单分为自定义菜单和个性化菜单，所谓自定义菜单，是所有用户看到相同的菜单，而个性化菜单，则表示根据不同用户看到不同的菜单。或者相同的菜单，不同的用户使用不同的效果。
微信个性化菜单包含于自定义菜单，是一种特殊的自定义菜单。
编写自定义菜单，首先得要获取点击菜单后跳转的网址，点击菜单后，才能够确定跳转到哪个网页，而要跳转网页，必须经过微信网页授权。
打开Applications/Wechat/views/Utils.py文件，之前已经在这个文件中写了一个get_WeChatClient函数，用于获取WeChatClient对象。
再增加两个函数，用以获取授权后的跳转地址，Utils.py文件全部内容如下：
from redis import Redis
from wechatpy.session.redisstorage import RedisStorage
from GeneralTools import Constents
from wechatpy.client import WeChatClient
from wechatpy.oauth import WeChatOAuth
def get_WeChatClient():
"""
获取WeChatClient对象
:return:WeChatClient对象
"""
redis_client = Redis.from_url(Constents.WECHATPY_ACCESS_TOKEN_CACHE)
session_interface = RedisStorage(
redis_client,
prefix="wechatpy"
)
return WeChatClient(
Constents.WECHAT_APPID,
Constents.WECHAT_APPSECRET,
session=session_interface
)
def get_WeChatOAuth(redirect_uri, state=‘123‘, scope=‘snsapi_userinfo‘):
"""
获取WeChatOAuth对象
:param redirect_uri: 授权后重定向的回调链接地址， 请使用 urlEncode 对链接进行处理
:param scope:应用授权作用域，snsapi_base，snsapi_userinfo
:param state:重定向后会带上state参数，开发者可以填写a-zA-Z0-9的参数值，最多128字节
:return: WeChatOAuth对象
"""
return WeChatOAuth(
app_id=Constents.WECHAT_APPID,
secret=Constents.WECHAT_APPSECRET,
redirect_uri=redirect_uri,
scope=scope,
state=state
)
def get_authorize_url(redirect_uri, state):
"""
获取授权跳转地址
:return: authorize_url
"""
wechatOAuth = get_WeChatOAuth(redirect_uri, state)
return wechatOAuth.authorize_url
自定义菜单包括创建自定义菜单，创建个性化菜单，查询自定义菜单，删除个性化菜单，删除自定义菜单几个接口。
