应用场景
现在网站都有客服系统，客服与user沟通时，掌握user的信息越多越方便沟通。这样就需要客服系统能够与网站的user系统对接，这样能够不用user告诉客服，就能够知道用户的order，account等相关信息。
此时系统需要api接口与web端后台对接。
测试了live800客服系统，由于没有官方Api接口，自己手写一个，特记录一下，方便后人。
基本逻辑
- 在调用live800的js后面加入info信息，将userid和username等信息传递live800
- 在live800客服端设置信任url和key值
- live800客户端请求信任url（/live-user），在客户端中加载此页面显示。
- live-user页面对应控制器api/live/getUserInfo，在控制器中，需要验证用户key，防止信息泄露
