【问题描述】：

我正在尝试构建一个 Linkedin API 代码，但发现一个奇怪的错误

Fatal error: Uncaught TypeError: Argument 1 passed to Dotenv\Dotenv::__construct() must be an instance of Dotenv\Loader, string given, called in E:\xampp\htdocs\linkedinpi\examples\index.php on line 16 and defined in E:\xampp\htdocs\linkedinpi\vendor\vlucas\phpdotenv\src\Dotenv.php:31 Stack trace: #0 E:\xampp\htdocs\linkedinpi\examples\index.php(16): Dotenv\Dotenv->__construct('E:\\xampp\\htdocs...') #1 main thrown in E:\xampp\htdocs\linkedinpi\vendor\vlucas\phpdotenv\src\Dotenv.php on line 31

我无法复制如何解决问题。

我已按照以下步骤进行

https://github.com/zoonman/linkedin-api-php-client 和 https://github.com/zoonman/linkedin-api-php-client/tree/master/examples

我已经通过 Composer 下载了 Vendor，这是我使用的代码

include_once dirname(__DIR__) . DIRECTORY_SEPARATOR . 'vendor/autoload.php';


    use LinkedIn\Client;
    use LinkedIn\Scope;


    $dotenv = new Dotenv\Dotenv(dirname(__DIR__));
    $dotenv->load();

    session_start();

    $client = new Client(
        getenv('[LINKEDIN CLIENT ID]'),
        getenv('[LINKEDIN CLIENT SECRET]')
    );


    if (isset($_GET['code']))  // we are returning back from LinkedIn with the code
        if (isset($_GET['state']) &&  // and state parameter in place
            isset($_SESSION['state']) && // and we have have stored state
            $_GET['state'] === $_SESSION['state'] // and it is our request
        ) 
            try 
                // you have to set initially used redirect url to be able
                // to retrieve access token
                $client->setRedirectUrl($_SESSION['redirect_url']);
                // retrieve access token using code provided by LinkedIn
                $accessToken = $client->getAccessToken($_GET['code']);
                h1('Access token');
                pp($accessToken); // print the access token content
                h1('Profile');
                // perform api call to get profile information
                $profile = $client->get(
                    'people/~:(id,email-address,first-name,last-name)'
                );
                pp($profile); // print profile information

            $share = $client->post(

【问题讨论】：

错误信息很容易解释。显示这方面的代码会很有帮助。

抱歉，我发布问题时无法添加代码。所以现在我添加了代码。

dirname(__DIR__) 是一个字符串。第一个参数应该是 Dotenv\Loader 的实例，如错误所示

阅读docs。他们展示了一个静态的 create 方法，它让你只传递一个 dir 路径。

请看我之前的评论。关注文档。

【参考方案1】：

更改为调用 Dotenv 类 自定义环境 --> 用于运行多个环境

包的 Git 链接：Git link for the package

 $dotenv = Dotenv\Dotenv::create(dirname(__DIR__), 'custom env');
 $dotenv->load();

当我从 laravel 5.8 迁移到 laravel 6

注意请添加帮助包，因为支持已从核心中删除 laravel 6 中的文件

【参考方案2】：

如果您使用的是 4.1...

Mutable init

$dotenv = Dotenv\Dotenv::createMutable(__DIR__, $evn_file);
$dotenv->load();

Immutable init

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__, $evn_file);
$dotenv->load();
