無法重新聲明類Google_Service_Drive

Question

我正在使用google api客戶端上傳文件進行驅動，運行了google developer網站中給出的快速入門示例以列出運行良好的文件。

為了在特定的父文件夾中插入文件，我正在使用兩個對象（請參見下面的兩行），這將導致以下所示的錯誤。

導致錯誤的行（第二行導致錯誤）：

$file = new Google_Service_Drive_DriveFile();
$parent = new Google_Service_Drive_ParentReference(); 

錯誤：

PHP Fatal error:  Cannot redeclare class Google_Service_Drive in C:\xampp\htdocs\driveapi\vendor\google\apiclient\src\Google\Service\Drive.php on line 729
PHP Stack trace:
PHP   1. {main}() C:\xampp\htdocs\driveapi\drive_client.php:0

PHP   4. Composer\Autoload\includeFile() C:\xampp\htdocs\driveapi\vendor\composer\ClassLoader.php:301

完整代碼：（我僅添加了最后兩行，其余的來自Google開發者網站）

請幫忙。

砧，我猜你遇到了我遇到的同樣的問題。 我按照此頁面上的“快速入門”說明進行操作：

https://developers.google.com/drive/v3/web/quickstart/php#前提條件

使用composer安裝appclient：1. *，然后說：

“下載並解壓縮此zip文件，然后將Drive.php復制到vendor / google / apiclient / src / Google / Service /中，替換現有文件。”

我遇到了同樣的錯誤並變得可疑，因此我檢查了GIT，並查看了該文件的歷史記錄：

https://github.com/google/google-api-php-client/blob/v1-master/src/Google/Service/Drive.php

您會注意到，Drive.php的“ v1-master”版本比2015年10月的先前版本短了近2,000行代碼。

最新版本中缺少“ Google_Service_Drive_ParentReference”的所有代碼（我一直在尋找Google_Service_Drive_Property類）。

我將代碼從GIT存儲庫的歷史記錄（2015年10月9日）中復制了到我的Drive.php文件中，現在可以正常工作了。

希望這可以幫助，
