我对 Dropbox PHP SDK 有疑问。几分钟后我有异常：'操作太慢了。过去 10 秒的传输速度低于 1024 字节/秒。我想它可能与 PHP 配置有关。我可以毫无问题地上传 100MB 的文件，但我无法上传更大的文件。我正在使用 chunkUploader（5MB 块）和 ng-file-upload

public function store(Request $request)
{
    $chunk_number = (int)$request->input('_chunkNumber');
    $chunk_size   = (int)$request->input('_chunkSize');
    $total_size   = (int)$request->input('_totalSize');
    $file         = $request->file('file');
    $file_content = file_get_contents($file->getRealPath());
    $total_chunks = floor($total_size/$chunk_size);

    //First chunk
    if($chunk_number == 0){
        $id = Dropbox::chunkedUploadStart($file_content);
        $expires_at = Carbon::now()->addMinutes(60);
        Cache::put('id', $id, $expires_at);
    }

    //Add new chunk
    if($chunk_number > 0 && $chunk_number <= $total_chunks){
        Dropbox::chunkedUploadContinue(Cache::get('id'), $chunk_number*$chunk_size, $file_content);
    }

    //Finish upload
    if($chunk_number == $total_chunks){
        Dropbox::chunkedUploadFinish(Cache::get('id'), '/file', Dropbox\WriteMode::add());
    }
}
