# Claim Checking

The claim checker manager is part of the checker component (`web-token/jwt-checker`).

`spomky-labs/jose` and this framework works a similar way thus migration is very easy. The main differences are:

* There are two managers: one for the claims, one for the headers.
* The manager only accepts an associative array. Conversion from a string to that array have to be done.

Checkers must implement the `Jose\Component\Checker\ClaimChecker` interface.

**Before**

```php
<?php

use Jose\Checker\CheckerManager;
use Jose\Checker\ExpirationTimeChecker;
use Jose\Checker\IssuedAtChecker;
use Jose\Checker\NotBeforeChecker;

$checkerManager = new CheckerManager();
$checkerManager->addClaimChecker(new ExpirationTimeChecker());
$checkerManager->addClaimChecker(new IssuedAtChecker());
$checkerManager->addClaimChecker(new NotBeforeChecker());

$checkerManager->checkJWS($jws, $signature_index);
```

**After**

```php
<?php

use Jose\Component\Checker\ClaimCheckerManager;
use Jose\Component\Checker\ExpirationTimeChecker;
use Jose\Component\Checker\IssuedAtChecker;
use Jose\Component\Checker\NotBeforeChecker;

$claimCheckerManager = new ClaimCheckerManager();
$claimCheckerManager->add(new ExpirationTimeChecker());
$claimCheckerManager->add(new IssuedAtChecker());
$claimCheckerManager->add(new NotBeforeChecker());

$claimCheckerManager->check($claims);
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://web-token.spomky-labs.com/1.x/migration/from-spomky-labs-jose/claim-checking.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
