Question

我跑sudo composer require lcobucci/jwt来安装这些东西。

然后，我在文件顶部添加了use Lcobucci\JWT\Configuration;

然后，我开始使用示例代码

        $config = new Configuration(); // This object helps to simplify the creation of the dependencies
                               // instead of using "?:" on constructors.
        $token = $config->createBuilder()
        ->issuedBy('https://login.uat.telenet.be/openid') // Configures the issuer (iss claim)
        ->canOnlyBeUsedBy('site') // Configures the audience (aud claim)
        ->identifiedBy('888254e8-f1e8-4956-86fa-a6c0f61a6421', true) // Configures the id (jti claim), replicating as a header item
        ->issuedAt(time()) // Configures the time that the token was issue (iat claim)
        ->canOnlyBeUsedAfter(time() + 60) // Configures the time that the token can be used (nbf claim)
        ->expiresAt(time() + 3600) // Configures the expiration time of the token (exp claim)
        ->with('uid', 1) // Configures a new claim, called "uid"
        ->getToken(); // Retrieves the generated token

        $token->getHeaders(); // Retrieves the token headers
        $token->getClaims(); // Retrieves the token claims

        echo $token->getHeader('jti'); // will print "4f1g23a12aa"
        echo $token->getClaim('iss'); // will print "http://example.com"
        echo $token->getClaim('uid'); // will print "1"
        echo $token; // The string representation of the object is a JWT string (pretty easy, right?)

我一直收到此错误

Class＆＃39; Lcobucci \ JWT \ Configuration＆＃39;找不到

我该如何预防？

这是我的整个 composer.json 文件

Answer 1

尝试运行composer dumpauto命令

Answer 2

您已安装该软件包的版本^3.2。如果查看此版本的代码和文档，则没有Configuration对象;有一个Builder对象。

如果你只是去https://github.com/lcobucci/jwt，你会看到他们的主分支。根据他们的文档，他们目前正在研究他们的下一个主要版本：

重要提示：这是我们下一个主要版本（v4）的文档，它将会改变。如果您使用的是稳定版本，则应转至分支3.2。

请务必查看您使用的版本的文档：

https://github.com/lcobucci/jwt/tree/3.2

这是他们的3.2（你正在使用的版本）的示例代码：

use Lcobucci\JWT\Builder;

$token = (new Builder())->setIssuer('http://example.com') // Configures the issuer (iss claim)
                        ->setAudience('http://example.org') // Configures the audience (aud claim)
                        ->setId('4f1g23a12aa', true) // Configures the id (jti claim), replicating as a header item
                        ->setIssuedAt(time()) // Configures the time that the token was issue (iat claim)
                        ->setNotBefore(time() + 60) // Configures the time that the token can be used (nbf claim)
                        ->setExpiration(time() + 3600) // Configures the expiration time of the token (nbf claim)
                        ->set('uid', 1) // Configures a new claim, called "uid"
                        ->getToken(); // Retrieves the generated token


$token->getHeaders(); // Retrieves the token headers
$token->getClaims(); // Retrieves the token claims

echo $token->getHeader('jti'); // will print "4f1g23a12aa"
echo $token->getClaim('iss'); // will print "http://example.com"
echo $token->getClaim('uid'); // will print "1"
echo $token; // The string representation of the object is a JWT string (pretty easy, right?)

Answer 3

首先删除供应商文件夹，然后尝试使用命令

重新安装作曲家。

composer update

尝试使用不同的方法已经遇到了两个多小时的问题，然后尝试执行此操作，我的问题已解决：D /
