使用 RSA-256 私钥在 jmeter 上生成 JWT 令牌

Question

So the thing is I want to run some test cases on jmeter that require a jwt authorization. That jwt must be generated using a private key (RSA-256).

Is there any way I can do this on jMeter?

Answer 1

You can do it using:

1. A suitable JWT Java Client library
2. A suitableJSR223 Test Element
3. A piece of Groovy code

Example approach assuming having JJWT library with dependencies inJMeter Classpath

def generator = java.security.KeyPairGenerator.getInstance("RSA");
generator.initialize(2048, new java.security.SecureRandom())
def keyPayr = generator.generateKeyPair()

def now = java.time.Instant.now()

def clientId = 'foo'

def jwt = io.jsonwebtoken.Jwts.builder()
        .setAudience('https://example.com')
        .setIssuedAt(Date.from(now))
        .setExpiration(Date.from(now.plus(5L, java.time.temporal.ChronoUnit.MINUTES)))
        .setIssuer(clientId)
        .setSubject(clientId)
        .setId(UUID.randomUUID().toString())
        .signWith(keyPayr.private)
        .compact()

log.info('Token: ' + jwt)
