An implementation of JSON Web Tokens.
This was developed against draft-ietf-oauth-json-web-token-08
. It makes use of node-jws
Install
$ npm install jsonwebtoken
Migration notes
Usage
jwt.sign(payload, secretOrPrivateKey, [options, callback])
(Asynchronous) If a callback is supplied, the callback is called with the err
or the JWT.
(Synchronous) Returns the JsonWebToken as string
payload
could be an object literal, buffer or string representing valid JSON.
Please note that
exp
or any other claim is only set if the payload is an object literal. Buffer or string payloads are not checked for JSON validity.
If
payload
is not a buffer or a string, it will be coerced into a string usingJSON.stringify
.
secretOrPrivateKey
is a string (utf-8 encoded), buffer, object, or KeyObject containing either the secret for HMAC algorithms or the PEM
encoded private key for RSA and ECDSA. In case of a private key with passphrase an object { key, passphrase }
can be used (based on crypto documentation), in this case be sure you pass the algorithm
option.
When signing with RSA algorithms the minimum modulus length is 2048 except when the allowInsecureKeySizes option is set to true. Private keys below this size will be rejected with an error.
options
:
algorithm
(default:HS256
)expiresIn
: expressed in seconds or a string describing a time span vercel/ms.Eg:

,"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 have been applied to it but before it has been encoded into a token.allowInsecureKeySizes
: if true allows private keys with a modulus below 2048 to be used for RSAallowInvalidAsymmetricKeyTypes
: if true, allows asymmetric keys which do not match the specified algorithm. This option is intended only for backwards compatability and should be avoided.
There are no default values for
expiresIn
,notBefore
,audience
,subject
,issuer
. These claims can also be provided in the payload directly withexp
,nbf
,aud
,sub
andiss
respectively, but you can't include in both places.
Remember that exp
, nbf
and iat
are NumericDate, see related Token Expiration (exp claim)
The header can be customized via the options.header
object.
Generated jwts will include an iat
(issued at) claim by default unless noTimestamp
is specified. If iat
is inserted in the payload, it will be used instead of the real timestamp for calculating other things like exp
given a timespan in options.expiresIn
.

Token Expiration (exp claim)
The standard for JWT defines an exp
claim for expiration. The expiration is represented as a NumericDate:
A JSON numeric value representing the number of seconds from 1970-01-01T00:00:00Z UTC until the specified UTC date/time, ignoring leap seconds. This is equivalent to the IEEE Std 1003.1, 2013 Edition [POSIX.1] definition "Seconds Since the Epoch", in which each day is accounted for by exactly 86400 seconds, other than that non-integer values can be represented. See RFC 3339 [RFC3339] for details regarding date/times in general and UTC in particular.
This means that the exp
field should contain the number of seconds since the epoch.
Signing a token with 1 hour of expiration:
// help.vue
// jsonwebToken
var jwt = require('jsonwebtoken');
// twe cifz
const signtoken = async (userdata) => {
return await jwt.sign({
data: userdata
}, 'aaaa', {
expiresIn: '2h'
});
}
Another way to generate a token like this with this library is:
// service.vue
const query = require('../db/query');
const CartAdd = async (params) => {
let sql = `insert into cart (userid,shopid,count) values ('${params.userid}','${params.shopid}','${params.count}')`
return await query(sql);
}
const CartShow = async (params) => {
let sql = `select a.*,b.name,b.price,a.count * b.price zprice from cart a join shop b on a.shopid = b.id where userid = ${params.userid}`
if (params.name) {
sql += ` and b.name like '%${params.name}%'`
}
let count = (await query(sql)).length;
sql += ` limit ${(params.page-1) * params.size},${params.size}`
let cartdata = await query(sql);
return {
cartdata,
count
};
}
const CartZprice = async (params) => {
let sql = ` select sum(a.count * b.price) zprice from cart a join shop b on a.shopid = b.id where userid = ${params.userid} and a.id in (${params.ids})`
return await query(sql);
}
const CartPutj = async (params) => {
let sql = `update cart set count = count - 1 where id = ${params.id}`;
return await query(sql);
}
const CartPuta = async (params) => {
let sql = `update cart set count = count + 1 where id = ${params.id}`;
return await query(sql);
}
const CartDel = async (params) => {
let sql = `delete from cart where id in (${params.ids})`;
return await query(sql);
}
// DC
const CartXls = async(params)=>{
let sql = `select * from cart`;
let cartdata = await query(sql);
let arr = [];
for(let i = 0;i<cartdata.length;i++){
arr[i] = [cartdata[i].shopid,cartdata[i].userid,cartdata[i].count]
}
return arr;
}
//or even better:
// order.vue
const query = require('../db/query');
const moment = require('moment');
const orderadd = async(params)=>{
let sql = `insert into orders (ordercode,shopid,userid,count,status,createtime,bz) values ('${params.ordercode}','${params.shopid}','${params.userid}','${params.count}','0','${params.createtime}','${params.bz}')`;
return await query(sql);
}
const ordershow = async(params)=>{
let sql = `select a.*,b.name,b.price from orders a join shop b on a.shopid = b.id where a.userid = ${params.userid}`;
if(params.status != -1 && params.status != undefined){
sql += ` and a.status = ${params.status}`;
}
return await query(sql);
}
const orderput = async(params)=>{
let newstatus = -1;
if(params.status == 0){
newstatus = 1;
}else if(params.status == 1){
newstatus = 2;
}else if(params.status == 2){
newstatus = 3;
}else if(params.status == 3){
newstatus = 4;
}else if(params.status == 4){
newstatus = 5;
}else if(params.status == 5){
newstatus = 6;
}
let sql = `update orders set status = ${newstatus} where id = ${params.id}`;
return await query(sql);
}
const orderdel = async(params)=>{
let sql = `delete from orders where id = ${params.id} and status = 6`;
return await query(sql);
}
const orderagain = async(params)=>{
let sql = `select * from orders where id = ${params.id}`;
let orderdata = await query(sql);
if(orderdata[0].status != 6){
return false;
}
let ordercode = Math.random().toFixed(10).slice(-10);
let createtime = moment().format('YYYY-MM-DD HH:mm:ss');
let sqlagain = `insert into orders (ordercode,shopid,userid,count,status,createtime,bz) values ('${ordercode}','${orderdata[0].shopid}','${orderdata[0].userid}','${orderdata[0].count}','0','${createtime}','${orderdata[0].bz}')`
return await query(sqlagain);
}
const orderbz = async(params)=>{
let sql = `update orders set bz ='${params.bz}'`;
return await query(sql);
}
jwt.verify(token, secretOrPublicKey, [options, callback])
(Asynchronous) If a callback is supplied, function acts asynchronously. The callback is called with the decoded payload if the signature is valid and optional expiration, audience, or issuer are valid. If not, it will be called with the error.
(Synchronous) If a callback is not supplied, function acts synchronously. Returns the payload decoded if the signature is valid and optional expiration, audience, or issuer are valid. If not, it will throw the error.
Warning: When the token comes from an untrusted source (e.g. user input or external requests), the returned decoded payload should be treated like any other user input; please make sure to sanitize and only work with properties that are expected
token
is the JsonWebToken string
secretOrPublicKey
is a string (utf-8 encoded), buffer, or KeyObject containing either the secret for HMAC algorithms, or the PEM
encoded public key for RSA and ECDSA.
If jwt.verify
is called asynchronous, secretOrPublicKey
can be a function that should fetch the secret or public key. See below for a detailed example
As mentioned in this comment, there are other libraries that expect base64 encoded secrets (random bytes encoded using base64), if that is your case you can pass Buffer.from(secret, 'base64')
, by doing this the secret will be decoded using base64 and the token verification will use the original random bytes.
options
algorithms
: List of strings with the names of the allowed algorithms. For instance,["HS256", "HS384"]
.If not specified a defaults will be used based on the type of key provided
- secret - ['HS256', 'HS384', 'HS512']
- rsa - ['RS256', 'RS384', 'RS512']
- ec - ['ES256', 'ES384', 'ES512']
- default - ['RS256', 'RS384', 'RS512']
audience
: if you want to check audience (aud
), provide a value here. The audience can be checked against a string, a regular expression or a list of strings and/or regular expressions.Eg:
"urn:foo"
,/urn:f[o]{2}/
,[/urn:f[o]{2}/, "urn:bar"]
complete
: return an object with the decoded{ payload, header, signature }
instead of only the usual content of the payload.issuer
(optional): string or array of strings of valid values for theiss
field.jwtid
(optional): if you want to check JWT ID (jti
), provide a string value here.ignoreExpiration
: iftrue
do not validate the expiration of the token.ignoreNotBefore
...subject
: if you want to check subject (sub
), provide a value hereclockTolerance
: number of seconds to tolerate when checking thenbf
andexp
claims, to deal with small clock differences among different serversmaxAge
: the maximum allowed age for tokens to still be valid. It is expressed in seconds or a string describing a time span vercel/ms.Eg:
1000
,"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"
).clockTimestamp
: the time in seconds that should be used as the current time for all necessary comparisons.nonce
: if you want to checknonce
claim, provide a string value here. It is used on Open ID for the ID Tokens. (Open ID implementation notes)allowInvalidAsymmetricKeyTypes
: if true, allows asymmetric keys which do not match the specified algorithm. This option is intended only for backwards compatability and should be avoided.

jwt.verify
instead.
Warning: When the token comes from an untrusted source (e.g. user input or external request), the returned decoded payload should be treated like any other user input; please make sure to sanitize and only work with properties that are expected

Refreshing JWTs
First of all, we recommend you to think carefully if auto-refreshing a JWT will not introduce any vulnerability in your system.
