使用js语言生成JWTtoken

##使用js语言生成token
const CryptoJS = require('crypto-js');
function getToken(secret,key,tokenName){
    var expTime = 3600;##token超时时间
    var header = {'typ': 'JWT','alg': 'HS256'};
    var currentTimestamp = Math.floor(new Date() / 1000);
    var data = {'iss': key,'iat': currentTimestamp,'exp': currentTimestamp +expTime};
    function base64url(source) {
        encodedSource = CryptoJS.enc.Base64.stringify(source);
        encodedSource = encodedSource.replace(/=+$/, '');
        return encodedSource;};
        var stringifiedHeader = CryptoJS.enc.Utf8.parse(JSON.stringify(header));
        var encodedHeader = base64url(stringifiedHeader);
        var stringifiedData = CryptoJS.enc.Utf8.parse(JSON.stringify(data));
        var encodedData = base64url(stringifiedData);
        var token = `${encodedHeader}.${encodedData}`;
        var signature = CryptoJS.HmacSHA256(token, secret);
        signature = base64url(signature);
        var signedToken = `${token}.${signature}`;
        pm.environment.set(tokenName, signedToken);
        };
var secret = pm.environment.get("secret");
var key = pm.environment.get("key");
getToken(secret,key,'token')

在postman中是这样使用的

 使用后效果是在请求头中添加一个Authorization。
