我有一个关于调用其他脚本的问题。

我想制作一个带有 ExactOnline 的 api……但我需要调用另一个我使用的脚本“需要DIR ”。这很好，但我的代码仍然没有得到脚本。有人可以向我解释为什么这不起作用吗？（我需要调用的脚本在“C:\xampp\htdocs\CM\EO\exactphpclientmaster\vendor\picqer\exactphpclient\src\Picqer\Financials\Exact\Connection.php”）

=错误=

Fatal error: Class 'vendor\picqer\exactphpclient\src\Picqer\Financials\Exact\Connection' not found in C:\xampp\htdocs\CM\EO\exactphpclientmaster\ConntectEO.php on line 3

=SCRIPT 即调用connection.php=

<?php
require __DIR__ . '\vendor\picqer\exactphpclient\src\Picqer\Financials\Exact\Connection.php';
$connection = new \vendor\picqer\exactphpclient\src\Picqer\Financials\Exact\Connection.php();
$connection->setRedirectUrl('**************************'); // Same as entered online in the App Center
$connection->setExactClientId('****************************************');
$connection->setExactClientSecret('************************');

if (getValue('authorizationcode')) // Retrieves authorizationcode from database
    $connection->setAuthorizationCode(getValue('authorizationcode'));

    if (getValue('accesstoken')) // Retrieves accesstoken from database
        $connection->setAccessToken(unserialize(getValue('accesstoken')));

        if (getValue('refreshtoken')) // Retrieves refreshtoken from database
            $connection->setRefreshToken(getValue('refreshtoken'));

            if (getValue('expires_in'))  // Retrieves expires timestamp from database
                $connection->setTokenExpires(getValue('expires_in'));

                // Make the client connect and exchange tokens
                try {
                    $connection->connect();
                } catch (\Exception $e)
                {
                    throw new Exception('Could not connect to Exact: ' . $e->getMessage());
                }

                // Save the new tokens for next connections
                setValue('accesstoken', serialize($connection->getAccessToken()));
                setValue('refreshtoken', $connection->getRefreshToken());

                // Optionally, save the expiry-timestamp. This prevents exchanging valid tokens (ie. saves you some requests)
                setValue('expires_in', $connection->getTokenExpires());

正如您提到您尝试加载 Connection 类如下

require __DIR__ . '\vendor\picqer\exactphpclient\src\Picqer\Financials\Exact\Connection.php';

当我们使用 composer 时，尝试使用composer auto load而不是加载单个类文件，它会自动加载所需类的名称空间。

如果您在代码中实现自动加载，代码可能如下所示。

require __DIR__ . '/vendor/autoload.php';

use Picqer\Financials\Exact\Connection;

$connection = new Connection();

错误本身是不言自明的。您正在尝试包含一个文件，但无法通过您提供的路径找到该文件。

尝试打印魔术常量 __DIR__包含的内容，以查看您尝试包含的完整路径。

您可以var_dump(__DIR__);exit;在脚本的开头使用。

作为附加说明，您应该考虑使用作曲家的 autoload。
