使用PHP下载带有Google Drive API的文件
我正在尝试制作一个系统,让我的服务器与Google drive中的一个装满照片的文件夹保持同步(单向) 到目前为止,我已经设法从github下载了PHP客户端库(我不使用composer),并列出了一些文件。我使用以下方法手动获取其中一张照片的id:使用PHP下载带有Google Drive API的文件,php,google-drive-api,Php,Google Drive Api,我正在尝试制作一个系统,让我的服务器与Google drive中的一个装满照片的文件夹保持同步(单向) 到目前为止,我已经设法从github下载了PHP客户端库(我不使用composer),并列出了一些文件。我使用以下方法手动获取其中一张照片的id: // Print the names and IDs for up to 10 files. $optParams = array( 'pageSize' => 10, 'fields' => "nextPageToke

print "Files:\n";
echo "<pre>";
print_r($results);

; 打印(下载文件($service,$file)); 下面是
printFile()
的响应,正如您所看到的,应该包含链接的字段显示为空白
我也不清楚API的v2和v3之间的区别,可能是它们弄乱了?它们似乎都使用相同的quickstart.php
code
感谢您的帮助!对于您的问题,驱动器v2和v3之间有什么区别。 以下是一些变化:
- v2中的
方法将成为v3中的getItems()
),而getFiles(
将成为getTitle()
getName()
- 默认情况下不再返回完整资源。请使用字段查询参数请求返回特定字段。如果未指定,则只返回常用字段的子集
- 所有更新操作现在都使用补丁而不是PUT
- exportLinks字段已从文件中删除。若要导出Google文档,请改用
方法文件。导出
downloadUrl
时,您需要获取文件的元数据。您可以使用该方法来实现这一点。该方法将返回一个表示形式。在该资源中,有一个downloadUrl
属性。如果您能够访问文件并获取URL,那么您的au应该没有问题身份验证设置。可能存在权限问题,您可能无法访问某些驱动器文件
