微信小程序设置消息回调通知_微信小程序服务通知回调

1. 登录微信公众号小程序后台 找到–>开发–>开发管理–>开发设置
2. 配置相关信息, 如图:
   
3. 修改或添加(注意: 必须选择xml 安全模式, 不然可能造成相关的回调结果为空)
   
4. 根据所填写的URl 域名地址 在服务端进行API 接口 编写 验证

示例代码:

class WeiXinToken(APIView):
    def get (self, request ):
        signature = request.GET.get ( 'signature' )
        timestamp = request.GET.get ( 'timestamp' )
        nonce = request.GET.get ( 'nonce' )
        echostr = request.GET.get ( 'echostr' )
        token = "*******填写后台配置的Token令牌********"
        tmpArr = [ token, timestamp, nonce ]
        tmpArr.sort ()
        string = ''.join ( tmpArr ).encode ( 'utf-8' )
        string = hashlib.sha1 ( string ).hexdigest ()
        if string == signature:
            return HttpResponse ( echostr )
        else:
            return HttpResponse ( "false" )

5. 验证成功之后,编写微信消息回调接口逻辑获取相应的回调结果
   回调结果需要解密, 解密包下载地址: c++, php, java, python, c# 5
   代码示例:

class WeiXinToken(APIView):
	"""当前只获取到了xml 信息, 后续更新"""
    def post(self,request):
        signature = request.GET.get ( 'signature' )
        timestamp = request.GET.get ( 'timestamp' )
        nonce = request.GET.get ( 'nonce' )
        msg_sign = request.GET.get ( 'msg_signature' )
        token = "*******填写后台配置的Token令牌********"
        encodingAESKey = "*****对应后台配置的消息加密密钥*****"
        _xml = request.body
        # 拿到微信发送的xml请求 即微信支付后的回调内容
        xml = str(_xml, encoding="utf-8")
        # 解密模块
        decrypt_test = WXBizMsgCrypt(token, encodingAESKey, APP_ID)
        ret, decryp_xml = decrypt_test.DecryptMsg(xml, msg_sign, timestamp, nonce)
        print(ret, decryp_xml)
        return HttpResponse("SUCCESS")
