# jsonwebtoken插件
一个生成json web token
的工具
const jwt = require("jsonwebtoken");
const secretKey = "secret";
const expiresIn = 60 * 60 * 24 * 1; // 单位为秒
function generateToken() {
const token = jwt.sign(
{
uid: 889898,
scope: 9,
},
secretKey,
{
expiresIn,
}
);
return token;
}
验证token,需要捕获错误
function verifyToken(token) {
try {
var decode = jwt.verify(token, secretKey);
// { uid: 889898, scope: 9, iat: 1602473422, exp: 1602559822 }
console.log(decode);
return true;
} catch (e) {
if (e.name === 'TokenExpiredError') {
console.log('token 已过期')
} else {
console.log('token 无效')
}
return false;
}
}
