文件移动 Google 驱动器 API v3 PHP

Question

使用 Google API v3 我尝试将文件从一个文件夹移动到另一个文件夹。我在 Laravel 中使用包装器 class，文件和父 ID 是正确的。从文档开发，我已经尝试过代码：

public function moveFileFromTo($fileID, $toParentID) {
    $fromFile = $this->service->files->get($fileID, ['fields' => '*']);
    $fromParentID = $fromFile->getParents();
    $blankFile = new Google_Service_Drive_DriveFile();
    $this->service->files->update($fileID, $blankFile, [
        "removeParents" => $fromParentID,
        "addParents" => $toParentID
    ]);
}

但是，这似乎移动了文件但删除了所有元数据。我也试过

public function moveFileFromTo($fileID, $toParentID) {
    $fromFile = $this->service->files->get($fileID, ['fields' => '*']);
    $fromParentID = $fromFile->getParents();
    $fromFile->setParents($fromParentID);
    $this->service->files->update($fileID, $fromFile);
}

然而，这给出了错误：

Google\Service\Exception
{ "error": { "errors": [ { "domain": "global", "reason": 
"fieldNotWritable", "message": "The resource body includes fields 
which are not directly writable." } ], "code": 403, "message": "The 
resource body includes fields which are not directly writable." } }

我希望简单地移动文件并保留其所有元数据。从文档中，似乎更新中需要一个新的空文件（真的很奇怪）或者我必须以某种方式删除第二个参数（$fromFile）中使用的对象的字段，它不喜欢被写入（即使我只是更新文件 parents - 这是可写的）。

另见 https://issuetracker.google.com/issues/199921300

目前回答的问题： 但感谢回复

$fromFile = $this->service->files->get($fileID, ['fields' => 'parents, id']);

returns 所有 ~75 个属性，其中很多是不可写的。而不是根据 PHPStorm 调试预期的 2（请注意，中断位于 GET 请求之后的语句中，因此此时无关紧要

使用

unset($fromFile->shared);

仍然保留其他可写属性

而且文件实际上并未共享

更新我的编码

public function moveFileFromTo($fileID, $toParentID) {
    $fromFile = $this->service->files->get($fileID, ["fields" => "id,parents"]);
    $fromFile = $this->getParsedWritableFile($fromFile);
    $fromFile->setParents($toParentID);
    $this->service->files->update($fileID, $fromFile, ['addParents' => $toParentID]);
}

getParsedWritableFile 正在尝试在新的 Google 驱动器文件对象上设置可写属性：

public function getParsedWritableFile($gdrivefile) {
        $gdrivefile = new \Google_Service_Drive_DriveFile();//comment or delete, just here to check auto complete function names

        $parsedFile = new \Google_Service_Drive_DriveFile();
        //$parsedFile=$gdrivefile;
        // currently only allow these according to https://developers.google.com/drive/api/v3/reference/files#resource-representations
        $parsedFile->setName($gdrivefile->getName());//name
        $parsedFile->setMimeType($gdrivefile->getMimeType());//mimeType
        $parsedFile->setDescription($gdrivefile->getDescription());//description
        $parsedFile->setStarred($gdrivefile->getStarred());//starred
        $parsedFile->setTrashed($gdrivefile->getTrashed());//trashed
        $parsedFile->setParents($gdrivefile->getParents());//parents
        $parsedFile->setProperties($gdrivefile->getProperties());//properties  [object]
        $parsedFile->setAppProperties($gdrivefile->getAppProperties());//appProperties [object]
        $parsedFile->setCreatedTime($gdrivefile->getCreatedTime());//createdTime
        $parsedFile->setModifiedTime($gdrivefile->getModifiedTime());//modifiedTime
        $parsedFile->setWritersCanShare($gdrivefile->getWritersCanShare());//writersCanShare
        $parsedFile->setViewedByMeTime($gdrivefile->getViewedByMeTime());//viewedByMeTime
        $parsedFile->setFolderColorRgb($gdrivefile->getFolderColorRgb());//folderColorRgb
        $parsedFile->setOriginalFilename($gdrivefile->getOriginalFilename());//originalFilename
        $parsedFile->setCopyRequiresWriterPermission($gdrivefile->getCopyRequiresWriterPermission());//copyRequiresWriterPermission

        /*complex permissions*/
        /*
        contentHints.thumbnail.image
        contentHints.thumbnail.mimeType
        contentHints.indexableText
         */
        $contenthints=$gdrivefile->getContentHints();//could be null meaning further functions eg getThumbnail cause exception
        if($contenthints){
            $parsedFile->setContentHints($contenthints->getThumbnail()->getImage());
            $parsedFile->setContentHints($contenthints->getThumbnail()->getMimeType());
            $parsedFile->setContentHints($contenthints->getIndexableText());
        }

        /*no function to get indiviual attributes*/
        /*
contentRestrictions[].readOnly
ccontentRestrictions[].reason
         */
        $parsedFile->setContentRestrictions($gdrivefile->getContentRestrictions());

        //</ end>
        return $parsedFile;
    }

这被证明有点成功，但这是原始元

上面的代码确实移动了它，看起来正确的元数据、创建时间和 EXIF 数据现在完好无损

我不知道如何在 laravel 但问题可能是

我也遇到过同样的问题，在互联网上搜索了几个月后一无所获，有一天参考 documentation，看到 shared 不是可写字段。

就是这样，如果您正在共享文件并尝试移动文件，它不会移动。尝试取消共享文件，然后尝试移动文件。

Answer 2

问题是您使用的是 file.update which uses HTTP PATCH 方法。通过使用 PATCH，它会尝试更新您发送的文件 object 中的所有属性。

您做了 file.get 并且包含了文件 *

 $fromFile = $this->service->files->get($fileID, ['fields' => '*']);

通过包含 'fields' => '*'，您将 API 至 return 告诉您该文件具有的所有属性。一个file resource有很多属性，并不是所有的都可以写。

通过向 file.update 方法发送您告诉它您想要更新所有内容的所有字段，包括您不允许更新的一些属性。 api 响应 fieldNotWritable

解决方案是执行以下操作

$fromFile = $this->service->files->get($fileID, ['fields' => 'parents, id']);

这将导致该方法仅 return 您实际需要的两个参数。 id 和 parents 参数。（说实话，您可能只需要 parents 部分，我需要对其进行测试。）

{
 "id": "1x8-vD-XiA5Spf3qp8x2wltablGF22Lpwup8VtxNY",
 "parents": ["0B1bbSFgVLpoXcVDRFRF8tTkU"
 ]
}

然后您应该可以更新 parent 并移动您的文件。

我最终创建了一个自定义函数，只包含 Google 文档中指定的可写属性：

public function getParsedWritableFile($gdrivefile) {
        $gdrivefile = new \Google_Service_Drive_DriveFile();//comment or delete, just here to check auto complete function names
        $parsedFile = new \Google_Service_Drive_DriveFile();

        // currently only allow these according to https://developers.google.com/drive/api/v3/reference/files#resource-representations
        $parsedFile->setName($gdrivefile->getName());//name
        $parsedFile->setMimeType($gdrivefile->getMimeType());//mimeType
        $parsedFile->setDescription($gdrivefile->getDescription());//description
        $parsedFile->setStarred($gdrivefile->getStarred());//starred
        $parsedFile->setTrashed($gdrivefile->getTrashed());//trashed
        $parsedFile->setParents($gdrivefile->getParents());//parents
        $parsedFile->setProperties($gdrivefile->getProperties());//properties  [object]
        $parsedFile->setAppProperties($gdrivefile->getAppProperties());//appProperties [object]
        $parsedFile->setCreatedTime($gdrivefile->getCreatedTime());//createdTime
        $parsedFile->setModifiedTime($gdrivefile->getModifiedTime());//modifiedTime
        $parsedFile->setWritersCanShare($gdrivefile->getWritersCanShare());//writersCanShare
        $parsedFile->setViewedByMeTime($gdrivefile->getViewedByMeTime());//viewedByMeTime
        $parsedFile->setFolderColorRgb($gdrivefile->getFolderColorRgb());//folderColorRgb
        $parsedFile->setOriginalFilename($gdrivefile->getOriginalFilename());//originalFilename
        $parsedFile->setCopyRequiresWriterPermission($gdrivefile->getCopyRequiresWriterPermission());//copyRequiresWriterPermission

        /*complex permissions*/
        /*
        contentHints.thumbnail.image
        contentHints.thumbnail.mimeType
        contentHints.indexableText
         */
        $contenthints=$gdrivefile->getContentHints();//could be null meaning further functions eg getThumbnail cause exception
        if($contenthints){
            $parsedFile->setContentHints($contenthints->getThumbnail()->getImage());
            $parsedFile->setContentHints($contenthints->getThumbnail()->getMimeType());
            $parsedFile->setContentHints($contenthints->getIndexableText());
        }

        /*no function to get indiviual attributes*/
        /*
contentRestrictions[].readOnly
ccontentRestrictions[].reason
         */
        $parsedFile->setContentRestrictions($gdrivefile->getContentRestrictions());
        return $parsedFile;
    }

并调用

public function moveFileFromTo($fileID, $toParentID) {
    $fromFile = $this->service->files->get($fileID, ["fields" => "id,parents"]);
    $fromFile = $this->getParsedWritableFile($fromFile);
    $fromFile->setParents($toParentID);
    $this->service->files->update($fileID, $fromFile, ['addParents' => $toParentID]);
}
