在Laravel找不到類5

Question

我跑sudo composer require lcobucci/jwt來安裝東西。

然後，我在我的文件的頂部添加use Lcobucci\JWT\Configuration;

然後，我開始使用示例代碼

 $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?) 

我不斷收到此錯誤

類「Lcobucci \智威湯遜\配置'找不到

我該如何預防？

Answer 1

你已經安裝的程序包^3.2版本。如果您查看此版本的代碼和文檔，則不存在Configuration對象;有一個Builder對象。

如果你只是去https://github.com/lcobucci/jwt，你會看到他們的主分支。根據他們的文檔，他們目前正在研究他們的下一個主要版本：

重要提示：這是我們下一個主要版本（v4）的文檔，它會改變。如果你正在使用穩定版本，你應該去分支3.2。

確保你看的版本的文檔使用的是：

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

這是3.2的示例代碼（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?)

嘗試運行composer dumpauto命令
