在页面中使用 button open-type="contact" / 可以显示进入客服会话按钮。button open-type="contact" class='contactService' session-from="{{'https://https://mp.weixin.qq.com/debug/wxadoc/introduction/image/x11.png'}}" hover-class="none"联系客服获取二维码/button

 当用户在客服会话发送消息（或进行某些特定的用户操作引发的事件推送时），微信服务器会将消息（或事件）的数据包（JSON或者XML格式）POST请求开发者填写的URL。开发者收到请求后可以使用发送客服消息接口进行异步回复。微信服务器在将用户的消息发给小程序的开发者服务器地址（开发设置处配置）后，微信服务器在五秒内收不到响应会断掉连接，并且重新发起请求，总共重试三次，如果在调试中，发现用户无法收到响应的消息，可以检查是否消息处理超时。关于重试的消息排重，有msgid的消息推荐使用msgid排重。事件类型消息推荐使用FromUserName + CreateTime 排重。服务器收到请求必须做出下述回复，这样微信服务器才不会对此作任何处理，并且不会发起重试，否则，将出现严重的错误提示。详见下面说明：1、直接回复success（推荐方式）2、直接回复空串（指字节长度为0的空字符串，而不是结构体中content字段的内容为空）

一旦遇到以下情况，微信都会在小程序会话中，向用户下发系统提示“该小程序客服暂时无法提供服务，请稍后再试”：1、开发者在5秒内未回复任何内容2、开发者回复了异常数据
