小程序转发客服消息使用easychat

需求：

收到小程序卡片时，发送公众号二维码让其绑定，收到其他信息转发到网页客服系统

实现

收到消息，响应时回复一段xml如下，

<xml>
    <ToUserName><![CDATA[touser]]></ToUserName>
    <FromUserName><![CDATA[fromuser]]></FromUserName>
    <CreateTime>1399197672</CreateTime>
    <MsgType><![CDATA[transfer_customer_service]]></MsgType>
</xml>

ps

1其中 FromUserName 为小程序原始id，

2经实际测试消息推送配置里数据格式选xml才可以
