未在Laravel 5中找到的类

Question

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

然后，我在我的文件上添加了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?)

我一直在犯这个错误

未找到类'Lcobucci\JWT\Configuration‘

我怎么才能防止这种情况？

这是我的整个composer.json文件

Answer 1

您已经安装了包的^3.2版本。如果查看此版本的代码和文档，就会发现没有Configuration对象；有一个Builder对象。

如果你只是去https://github.com/lcobucci/jwt，你将看到他们的主分支。根据他们的文件，他们目前正在编写下一个主要版本：

重要:这是我们下一个主要版本(v4)的文档，它将发生变化。如果您正在使用稳定版本，则应该转到分支3.2。

请确保查看正在使用的版本的文档：

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

这是3.2的示例代码(您正在使用的版本)：

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 2

尝试运行composer dumpauto命令

Answer 3

首先，删除供应商文件夹并尝试使用命令重新安装composer

composer update 

已经面对一个问题两个多小时了，尝试不同的方法，然后尝试这个，我的问题解决了。
