用django实现一个微信图灵机器人

微信的post请求格式是xml，所以django需要做的就是将xml请求解析出来，把content发送到图灵机器人接口，接口返回的json数据把主要内容给解析出来，然后重新封装成xml返回给微信客户端。如果只做文本处理，可以直接修改views.py的responseMsg函数即可，其他代码可以固定不变。

urls.py

from django.conf.urls import patterns, include, url
from littesnail.views import handleRequest

urlpatterns = patterns('',
    # Examples:
    url(r'^$', handleRequest),
)

views.py

        replyContent= content
    else:

    replyContent = content
    return getReplyXml(msg,replyContent)

def paraseMsgXml(rootElem):
    msg = {}
    if rootElem.tag == 'xml':
        for child in rootElem:
            msg[child.tag] = smart_str(child.text)
    return msg


def getReplyXml(msg,replyContent):
    for i in range(1,1000):
        extTpl = "<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[%s]]></MsgType><Content><![CDATA[%s]]></Content><FuncFlag>0</FuncFlag></xml>";
        extTpl = extTpl % (msg['FromUserName'],msg['ToUserName'],str(int(time.time())),'text',replyContent)
        return extTpl
