我不得不使用Swagger-php包来使用api，我在composer服务中安装了这个包，它包含在composer.json文件中，但是当使用方法时，这个包给了我一个class ... not found错误，我第一次遇到这个问题，我无法通过Google搜索找到有用的答案。
注意：我安装这个软件包的方式与之前的软件包相同，所有软件包都相互响应（composer require [package name]）

• composer.json文件的内容

{
    "require": {
        "guzzlehttp/guzzle": "^7.0",
        "phpmailer/phpmailer": "^6.2",
        "swiftmailer/swiftmailer": "^6.0",

        "doctrine/annotations": "^1.11",
        "sendinblue/api-v3-sdk": "7.x.x"
   }

• 文件autoload_real.php的内容

• 错误文本：

Fatal error: Uncaught Error: Class "Swagger\Client\Configuration" not found ...

• 我做的事情：

1 -我更新 composer
2 -我将包存储库插入composer.json

,"repositories": [
        {
            "type": "vcs",
            "url":  "git@bitbucket.org:vendor/my-private-repo.git"
        }
    ]

3 -composer dumpautoload和composer run

• 我不想改变psr4，因为我不知道怎么做

我的代码：

<?php
require_once("/home/milad/vendor/autoload.php");

// Configure API key authorization: apieco-key
Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('7UHoMOuKT0bgYv0FmG9xFi70d11DVP0C', 'YOUR_API_KEY');
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Swagger\Client\Configuration::getDefaultConfiguration()->setApiKeyPrefix('apieco-key', 'Bearer');

$api_instance = new Swagger\Client\Api\ConditionsApi();
$apiecoKey = "7UHoMOuKT0bgYv0FmG9xFi70d11DVP0C"; // String | 
$age = "40"; // String | age
$enableTriage5 = true; // Boolean | enable 5-level triage values

try {
    $result = $api_instance->conditions($apiecoKey, $age, $enableTriage5);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling ConditionsApi->conditions: ', $e->getMessage(), PHP_EOL;
}
?>
