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

    if request.method == 'GET':

        response = HttpResponse(checkSignature(request),content_type="text/plain")

        return response

        response = HttpResponse(responseMsg(request),content_type="application/xml")

        return response

    else:

    tmpList.sort()

    tmpstr = "%s%s%s" % tuple(tmpList)

    tmpstr = hashlib.sha1(tmpstr).hexdigest()

    if tmpstr == signature:

        return echoStr

    queryStr = msg.get('Content','You have input nothing~')

    raw_tulingURL = "http://www.tuling123.com/openapi/api?key=%s&%s&info=" % (API_KEY,USER_ID)

    hjson=json.loads(raw_json)

    length=len(hjson.keys())

    content=hjson['text'].encode('utf-8')

    if length==3:

        replyContent= "%s%s"%(content,hjson['url'].encode('utf-8'))

    elif length==2:

        replyContent= content

    else:

        return "please input again."

    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
