Python微信企业号开发之回调模式接收微信端客户端发送消息及被动返回消息示例_Python

本文实例讲述了Python 微信企业号开发之回调模式接收微信端客户端发送消息及被动返回消息。分享给大家供大家参考，具体如下：

说明：此代码用于接收手机微信端发送的消息

									#-*- coding:utf-8 -*-

									from flask import Flask,request

									from WXBizMsgCrypt import WXBizMsgCrypt

									import xml.etree.cElementTree as ET

									import sys

									app = Flask(__name__)

									@app.route('/index',methods=['GET','POST'])

									def index():

									    sToken = 'Uxxxx'

									    sEncodingAESKey = 'U2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

									    sCorpID = 'wx1xxxxxxxxxxxxx'

									    wxcpt=WXBizMsgCrypt(sToken,sEncodingAESKey,sCorpID)

									    #获取url验证时微信发送的相关参数

									    sVerifyMsgSig=request.args.get('msg_signature')

									    sVerifyTimeStamp=request.args.get('timestamp')

									    sVerifyNonce=request.args.get('nonce')

									    sVerifyEchoStr=request.args.get('echostr')

									    #

									    sReqMsgSig = sVerifyMsgSig

									    sReqTimeStamp = sVerifyTimeStamp

									    sReqNonce = sVerifyNonce

									    #

									    sResqMsgSig = sVerifyMsgSig

									    sResqTimeStamp = sVerifyTimeStamp

									    sResqNonce = sVerifyNonce

									    #验证url

									    if request.method == 'GET':

									        ret,sEchoStr=wxcpt.VerifyURL(sVerifyMsgSig, sVerifyTimeStamp,sVerifyNonce,sVerifyEchoStr)

									        print type(ret)

									        print type(sEchoStr)

									        if (ret != 0 ):

									            print "ERR: VerifyURL ret:" + ret

									            sys.exit(1)

									        return sEchoStr

									    #接收客户端消息

									    if request.method == 'POST':

									        #sReqMsgSig = request.form.get('msg_signature')

									        #sReqTimeStamp = request.form.get('timestamp')

									        #sReqNonce = request.form.get('nonce')

									        #赋值url验证请求相同的参数，使用上面注释掉的request.form.get方式获取时，测试有问题

									            sReqMsgSig = sVerifyMsgSig

									            sReqTimeStamp = sVerifyTimeStamp

									            sReqNonce = sVerifyNonce

									        sReqData = request.data

									        print sReqData

									        ret,sMsg=wxcpt.DecryptMsg( sReqData, sReqMsgSig, sReqTimeStamp, sReqNonce)

									        if (ret != 0):

									            print "ERR: VerifyURL ret:"

									            sys.exit(1)

									        #解析发送的内容并打印

									        xml_tree = ET.fromstring(sMsg)

									        content = xml_tree.find("Content").text

									        print content

									    #被动响应消息，将微信端发送的消息返回给微信端

									    sRespData = '''<xml>

									            <ToUserName><![CDATA[mycreate]]></ToUserName>

									            <FromUserName><![CDATA[wx177d1233ab4b730b]]></FromUserName>

									            <CreateTime>1348831860</CreateTime>

									            <MsgType><![CDATA[text]]></MsgType>

									            <Content><![CDATA[''' +content +''']]></Content>

									            <MsgId>1234567890123456</MsgId>

									            <AgentID>1</AgentID>

									            </xml>'''

									    ret,sEncryptMsg=wxcpt.EncryptMsg(sRespData, sReqNonce, sReqTimeStamp)

									    if( ret!=0 ):

									        print "ERR: EncryptMsg ret: " + ret

									        sys.exit(1)

									    return sEncryptMsg

									if __name__ == '__main__':

									    app.run(host='0.0.0.0',port=6000,debug=True)

希望本文所述对大家Python程序设计有所帮助。
