在 Laravel 中获取“move_uploaded_file(): failed to open stream: Permission denied”错误

Question

提交表单后，我可以看到文件名、大小等，但我无法上传，因为它一直说权限被拒绝。我将 myapp/storage 的所有者更改为 www-data:www-data 并做到了

php artisan cache:clear 

chmod -R 777 myapp/storage 

这里建议：'Failed to open stream: Permission denied' error - Laravel，但没有帮助。

我的表单是用<form> <input> 标签创建的，而不是{{ Form }} 元素，所以我用move_uploaded_file() 而不是Input::file()->move() 上传它。

我在浏览器和终端中使用 ls -l 截取了错误消息，但我还不能发布图片：/

我要提交的原始表单不是带有操作、方法的表单...我使用 ajax 提交它，但由于这不起作用，我制作了一个只有 2 个输入的小表单来查看发生了什么...... .它说权限被拒绝

编辑 2： 错误信息：

最好使用移动功能将文件上传到公共文件夹。这样您就可以更轻松地从应用程序中的任何位置访问该文件。

//For access the file
$file = $request->file('image');

//Display File Name

echo 'File Name: '.$file->getClientOriginalName();
  echo '<br>';

  //Display File Extension
  echo 'File Extension: '.$file->getClientOriginalExtension();
  echo '<br>';

  //Display File Real Path
  echo 'File Real Path: '.$file->getRealPath();
  echo '<br>';

  //Display File Size
  echo 'File Size: '.$file->getSize();
  echo '<br>';

  //Display File Mime Type
  echo 'File Mime Type: '.$file->getMimeType();

  //Move Uploaded File
  $destinationPath = 'uploads';
  $file->move($destinationPath,$file->getClientOriginalName());

上面的移动功能会上传文件的真实名称（原始文件名）。如果你想自定义它，你可以使用 uniqid() 函数来生成一个唯一的文件名，

//Move Uploaded File
$up_name = uniqid();
$destinationPath = 'uploads';
$file->move($destinationPath, $up_name );

我终于解决了这个问题。 我将 www-data:www-data 设置为文件夹存储的所有者，但它一直在说

unable to create '/upload' directory

我将目的地设置为 './upload' 带有点“。”

它仍然说

file was not uploaded due to an unknown error

但是当我（不小心）检查公用文件夹文件时...

我不知道为什么它说它由于错误而没有上传，但它每次都会上传文件所以对我来说它适用于那个点。
