lc-js-common

项目中，用到的一些公共函数方法集合。

使用方法

jwt = jsonWebToken(key) jwt.sign(payload, secretOrPrivateKey options:

algorithm (default: HS256)
expiresIn: expressed in seconds or a string describing a time span zeit/ms.
Eg: 60, "2 days", "10h", "7d". A numeric value is interpreted as a seconds count. If you use a string be sure you provide the time units (days, hours, etc), otherwise milliseconds unit is used by default ("120" is equal to "120ms").
notBefore: expressed in seconds or a string describing a time span zeit/ms.
Eg: 60, "2 days", "10h", "7d". A numeric value is interpreted as a seconds count. If you use a string be sure you provide the time units (days, hours, etc), otherwise milliseconds unit is used by default ("120" is equal to "120ms").

mutatePayload: if true, the sign function will modify the payload object directly. This is useful if you need a raw reference to the payload after claims
