Question

当我的表单提交时，我可以看到文件名，大小等但我无法上传它，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并执行了

php artisan cache:clear 

chmod -R 777 myapp/storage

正如此处所建议的那样：'Failed to open stream: Permission denied' error - Laravel，但它没有帮助。

我的表单是使用<form> <input>标记创建的，而不是{{ Form }}个元素，因此我使用move_uploaded_file()而不是Input::file()->move()上传。

我使用ls -l在浏览器和终端中截取了错误消息的屏幕截图，但我还是无法发布图片：/

我要提交的原始表单不是带有操作，方法的表单...我用ajax提交它，但由于那不起作用我只用2个输入做了一个小表单来看看发生了什么... 。并表示许可被拒绝

Answer 1

最好使用移动功能将文件上传到Public文件夹。然后，您可以更轻松地从应用程序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());

以上移动功能将上传文件的真实姓名（原始文件名）。如果要自定义它，可以使用uniqid（）函数生成唯一的文件名

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

Answer 2

我终于解决了这个问题。我有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

我将目的地设定为 './upload' 带点＆＃39;。＆＃39;

它仍然说

file was not uploaded due to an unknown error

但是当我（不小心）检查公共文件夹文件时...

我不知道为什么它因为错误而没有上传，但每次都上传文件所以对我来说它适用于那个点。

在Laravel中获取“move_uploaded_file（）：无法打开流：权限被拒绝”错误
