Laravel Heroku应用程序错误

Question

我正在开发一个Laravel 5.4应用程序。我已将它部署到Heroku，running on free dyno，一切正常。我正在使用谷歌驱动器作为我的云存储。上传文件后，大小为200 MB，我收到此错误：

                          Application error

An error occurred in the application and your page could not be served.
 If you are the application owner, check your logs for details.

我在我的项目根目录中保存了一个.user.ini，我编辑过这样的：

post_max_size = 450M

upload_max_filesize = 400M

memory_limit =800M

我试图拖尾日志，但没有指出错误。

文件上传控制器：

public function fileupolad(Request $request){

$files = $request->file('files');

if($request->hasFile('files')){


foreach ($files as $file) {

   $filedata=new NameFile;

  $subject = $request->input('subject');
  $type = $request->input('type');

  $extension = $file->getClientOriginalExtension();
  $name = $file->getClientOriginalName();

  $onlyname=basename($file->getClientOriginalName(), '.'.$file-
  >getClientOriginalExtension());

   $myfile=Storage::disk('google')->put($name,File::get($file));

   $listContents = Storage::disk('google')->listContents();

  $fileid = $this->getId($listContents, 'filename', $onlyname);

  $id = $fileid['path'];
  $filedata->file=$file->getClientOriginalName();;

   $filedata->subject_id=$subject;

   $filedata->fileid=$id;
   $filedata->type=$type;
   $filedata->extension=$extension;

   $filedata->save();

}

}

}

更新：

我已经像这样更改了上传控制器：

$myfile=Storage::disk('google')->put($name,fopen($file,'r+'));

上传文件时，如果有人试图进入我的网站，他们将面临Application Error。

现在，我收到此错误日志。

Answer 1

问题是您在将文件保存到存储磁盘之前将文件读入内存。有一个更简单的方法来执行此操作，默认情况下使用流式传输并解决任何内存问题。我已经在免费的Heroku dyno上使用1GB文件上传成功测试了这个，并且没有内存或锁定问题。

请注意，此示例使用S3，但如果您使用适用于Google的Flysystem驱动程序，则它具有相同的基本概念。关键是我们没有创建一个读取完整文件的变量，我们只是将文件从Request直接传递到存储。默认情况下，这会让我们回到$path，因此您可以避免额外调用listContents()

    public function store(Request $request)
    {
        if ($request->hasFile('file')) {

            $path = $request->file('file')->store('/', 's3');

            return $path;
        }

    }

唯一需要确保的是你的php.ini覆盖（在.user.ini中）匹配你想要支持的最大文件大小。
