处理微信发来的信息，，实际上就是处理xml的过程，先写xml工具类
# -*- coding:utf-8 -*-from xml.dom import minidomfrom Web.model.WeiXin import *def get_attrvalue(node, attrname):return node.getAttribute(attrname) if node else ''def get_nodevalue(node, index = 0):return node.childNodes[index].nodeValue if node else ''def get_xmlnode(node,name):return node.getElementsByTagName(name) if node else []def xml_to_string(xml):doc = minidom.parse(xml)return doc.toxml('UTF-8')def get_xml_data(xml):doc = minidom.parseString(xml)root = doc.documentElementToUserName = get_nodevalue(get_xmlnode(root,'ToUserName')[0]).encode('utf-8','ignore')FromUserName = get_nodevalue(get_xmlnode(root,'FromUserName')[0]).encode('utf-8','ignore')CreateTime = get_nodevalue(get_xmlnode(root,'CreateTime')[0]).encode('utf-8','ignore')MsgType = get_nodevalue(get_xmlnode(root,'MsgType')[0]).encode('utf-8','ignore')Content = get_nodevalue(get_xmlnode(root,'Content')[0]).encode('utf-8','ignore')MsgId = get_nodevalue(get_xmlnode(root,'MsgId')[0]).encode('utf-8','ignore')return WeiXin(ToUserName=ToUserName,FromUserName=FromUserName,CreateTime=CreateTime,MsgType=MsgType,Content=Content,MsgId=MsgId)if __name__ =='__main__':xml = '<xml><ToUserName><![CDATA[gh_d740805e3dda]]></ToUserName><FromUserName><![CDATA[otvK9uEl5TdgfKaDtBhSb6CM49Xs]]></FromUserName><CreateTime>1426579233</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[哈哈]]></Content><MsgId>6127111151090981083</MsgId></xml>'print get_xml_data(xml)
封装一个微信xml实体类：__author__ = 'zan'class WeiXin():def __init__(self,ToUserName,FromUserName,CreateTime,MsgType,Content,MsgId):self.ToUserName= ToUserNameself.FromUserName= FromUserNameself.CreateTime= CreateTimeself.MsgType= MsgTypeself.Content= Contentself.MsgId= MsgIddef __repr__(self):return 'ToUserName=%s,\n FromUserName=%s,\nCreateTime=%s,\n,MsgType=%s,\nContent=%s,\nMsgId=%s\n' %(self.ToUserName,self.FromUserName,self.CreateTime,self.MsgType,self.Content,self.MsgId)最后解析xml，并返回xmldef weixin(requset):print 'requset.body=========%s'%requset.bodyif not requset.body.strip():return HttpResponse('error')weixinObj = get_xml_data(requset.body)print '解析之前 %s'%weixinObjtoUserName = weixinObj.FromUserName;fromUserName = weixinObj.ToUserName;weixinObj.FromUserName = fromUserName;weixinObj.ToUserName = toUserName;print '解析之后 %s'%weixinObjresult = '<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[%s]]></MsgType><Content><![CDATA[%s]]></Content><MsgId>%s</MsgId></xml>'%(weixinObj.ToUserName,weixinObj.FromUserName,weixinObj.CreateTime,weixinObj.MsgType,weixinObj.Content,weixinObj.MsgId)return HttpResponse(result)
而只有在充满了艰辛的人生旅途中，
