PHP-SPO上载大文件-请求消息太大

我正在使用PHP-SPO（）将文件从我的Web服务器上载到Sharepoint。它可以工作，但大型文件除外，我在其中收到消息“请求消息太大。服务器不允许Sharepoint中的消息大于2097152字节”

这是我目前的代码：

$targetLibraryTitle = 'Backups/Chamilo/' . $chamiloCode . '/';
$parentFolder = $this->sharePointAPI->getWeb()->getFolderByServerRelativeUrl(dirname($targetLibraryTitle));
$parentFolder->getFolders()->add(basename($targetLibraryTitle));
$this->sharePointAPI->executeQuery();
$targetList = $this->sharePointAPI->getWeb()->getLists()->getByTitle($targetLibraryTitle);

try {
    $fileCreationInformation = new FileCreationInformation();
    $fileCreationInformation->Content = file_get_contents($filePath);
    $fileCreationInformation->Url = basename($filePath);
    $uploadFile = $this->sharePointAPI->getWeb()
                ->getFolderByServerRelativeUrl($targetLibraryTitle)
                ->getFiles()
                ->add($fileCreationInformation);
    $this->sharePointAPI->executeQuery();
} catch (\Exception $e) {
    dd(__FILE__ . ' - regel: ' . __LINE__, $chamiloCode, $e->getMessage());
}

我知道这与Sharepoint设置的限制有关。但我找不到解决办法

请帮忙

蒂姆，所以我把它修好了。无法上载图形大于4MB的文件。 所以我用了这个脚本：

$subFolder = 'Chamilo/' . $chamiloCode;
$fileName = basename($filePath);
try {
    $reqBody = [
        '@microsoft.graph.conflictBehavior' => 'rename | fail | replace',
        'description'                       => 'backup ' . $chamiloCode,
        'fileSystemInfo'                    => ['@odata.type' => 'microsoft.graph.fileSystemInfo'],
        'name'                              => $fileName,
    ];
    $uploadSession = $this->graphClient->createRequest(
            self::REQUEST_TYPE_POST,
            self::APP_ENDPOINT_DRIVES
            . '/' . self::SHAREPOINT_GROUP_IT_BACKUP_FOLDER_ID . '/root:/'
            . $subFolder . '/' . $fileName
            . ':/createUploadSession'
        )
        ->attachBody($reqBody)
        ->setReturnType(Office365UploadSession::class)
        ->execute();

    $handle = fopen($filePath, 'rb');
    $fileSize = fileSize($filePath);
    $chunkSize = 1024 * 1024 * 4;
    $numberOfFragments = ceil($fileSize / $chunkSize);

    while (!feof($handle)) {
        $currentPosition = ftell($handle);
        $contents = fread($handle, $chunkSize);
        $nextPosition = ftell($handle);

        $resp = $this->graphClient->createRequest(self::REQUEST_TYPE_PUT, $uploadSession->getUploadUrl())
                ->addHeaders(
                    [
                        'Connection'     => 'keep-alive',
                        'Content-Length' => (strlen($contents)),
                        'Content-Range'  => 'bytes ' . $currentPosition
                           . '-' . ($nextPosition - 1)
                           . '/' . $fileSize,
                    ]
                )
                ->setReturnType(Office365UploadSession::class)
                ->attachBody($contents)
                ->execute();
            }
 } catch (\Exception $e) {
    $this->handleException($e);
 }
