使用 navigator 读取识别 ukey,报出这个问题,在本地是可以的,但是在测试环境上就出问题了,报
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'getDevices')
查询了好多地方,各种修改都报错。
突然详情,浏览器的api是否和ssl有关系,正式环境使用的是 https,使用没有问题,但是在测试环境使用的http,使用https访问就不会有这个问题了。
在这儿可以印证需要这个操作

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
所以,非本地访问,得使用https访问。
