无法重新声明Google

无法重新声明Google_Service_Drive类(Cannot redeclare class Google_Service_Drive)

我正在使用谷歌api客户端上传文件到驱动器，运行谷歌开发者网站提供的快速启动示例列出工作正常的文件。

为了在特定的父文件夹中插入文件，我使用了两个对象（请参阅下面的两行），这些对象导致下面显示的错误。

导致错误的行（第二行导致错误）：

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

错误：

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 2. spl_autoload_call() C:\xampp\htdocs\driveapi\drive_client.php:92 PHP 3. Composer\Autoload\ClassLoader->loadClass() C:\xampp\htdocs\driveapi\drive_client.php:92 PHP 4. Composer\Autoload\includeFile() C:\xampp\htdocs\driveapi\vendor\composer\ClassLoader.php:301

完整代码:(我只添加了最后两行，其余来自谷歌开发者网站）

<?php require __dir__ . '/vendor/autoload.php'; define('APPLICATION_NAME', 'drivephp'); define('CREDENTIALS_PATH', '~/.credentials/drive-php-quickstart.json'); define('CLIENT_SECRET_PATH', __dir__ .

请帮忙。

I am using google api client for uploading a file to drive, ran the quickstart example given in google developer site to list the files which is working fine.

In order to insert a file in specific parent folder I am using two objects (see the two lines below) which are causing an error shown below.

Lines that are causing error (second line is causing the error):

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

Error:

Full code: (only last two lines are added by me, rest is from google developer site)

Please help.

avil，我猜你遇到了我遇到的同样的问题。我按照此页面上的“快速入门”说明操作：

https://developers.google.com/drive/v3/web/quickstart/php#prerequisites

安装appclient：1. *使用composer然后它说：

“下载并解压缩此zip文件并将Drive.php复制到vendor / google / apiclient / src / Google / Service /，替换现有文件。”

我得到了同样的错误并且变得可疑，所以我检查了GIT并查看了这个文件的历史记录：

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

您会注意到Drive.php的“v1-master”版本比2015年10月的早期版本短近2000行代码。

最新版本中缺少“Google_Service_Drive_ParentReference”（我正在寻找Google_Service_Drive_Property类）的所有代码。

我将GIT repo的历史记录（2015年10月9日）中的代码复制到我的Drive.php文件中，现在工作正常。

希望这可以帮助，

avil, I'm guessing you ran into the same issue that I ran into. I followed the "quickstart" instructions on this page:

https://developers.google.com/drive/v3/web/quickstart/php#prerequisites

to install the appclient:1.* using composer and it then says to:

"Download and extract this zip file and copy Drive.php to vendor/google/apiclient/src/Google/Service/, replacing the existing file."

I got the same error and became suspicious so I checked on GIT and looked at the history of this file:

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

You'll notice that the "v1-master" version of Drive.php is almost 2,000 lines of code shorter than the prior release in October 2015.

All of the code for your "Google_Service_Drive_ParentReference" (I was looking for the Google_Service_Drive_Property class) is missing from the newest release.

I literally copied the code from the GIT repo's History (Oct 9 2015) into my Drive.php file and it's working fine now.

Hope this helps,
