Laravel 5.3使用AJAX错误上传52张图像

问题描述：

I have a problem. I'm using Bootstrap fileinput to upload 52 images with async AJAX requests. It uploads 90% of the files and randomly gives errors on few of the images.

This is the error:

SQLSTATE[HY000] [1045] Access denied for user 'forge'@'localhost' (using password: NO)

Upload function:

public function uploadTemp360(Request $request)
{
    $image = $request->file('view360s');
    $fileName = $image->getClientOriginalName().'.'.$image->getClientOriginalExtension();
    $path = public_path().'/uploads/temp/';

    if ($image->isValid()){
        $image->move($path, $fileName);
    }

    return [
        'initialPreview' => [
            "<img  style='height:160px' src='/uploads/temp/".$fileName."' class='file-preview-image'>",
        ],
        'initialPreviewConfig' => [
            ['caption' => $fileName, 'width' => '120px', 'url' => route('admin.products.delete-temp-360'), 'key' => $fileName, 'size' => \File::size($path.$fileName)],
        ],
        'append' => true,
        'filename' => $fileName,
    ];
}

I don't know what's going on and how is it causing DB error by running this code...

I have found in laravel log this error: production.ERROR: exception 'RuntimeException' with message 'The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths.'

我遇到了问题。我正在使用Bootstrap fileinput上传52个带有异步AJAX请求的图像。它上传了90％的文件并在少数图像上随机出现错误。 p>

这是错误： p>

SQLSTATE [HY000 ] [1045]用户“伪造”@“localhost”的访问被拒绝（使用密码：否） code> p>

上传功能： p>


   public function uploadTemp360（Request $ request）
 {
 $ image = $ request-＆gt; file（'view360s'）; 
 $ fileName = $ image-＆gt; getClientOriginalName（）。'。'。$。  image-＆gt; getClientOriginalExtension（）; 
 $ path = public_path（）。'/ uploads / temp /'; 
 
 if（$ image-＆gt; isValid（））{
 $ image-＆gt; move（  $ path，$ fileName）; 
} 
 
返回[
'initialPreview'=＆gt;  [
“＆lt; img style ='height：160px'src ='/ uploads / temp /".$ fileName。”'class ='file-preview-image'＆gt;“，
]，
'initialPreviewConfig  '=＆gt;  [
 ['caption'=＆gt;  $ fileName，'width'=＆gt;  '120px'，'url'=＆gt;  route（'admin.products.delete-temp-360'），'key'=＆gt;  $ fileName，'size'=＆gt;  \ File :: size（$ path。$ fileName）]，
]，
'append'=＆gt;  true，
'filename'=＆gt;  $ fileName，
]; 
} 
  code>  pre> 
 
 我不知道发生了什么，以及如何通过运行此代码导致数据库错误...  
 
 
我在laravel中发现了这个错误：
  production.ERROR：异常'RuntimeException'，带有消息'唯一支持的密码是AES-128-CBC和AES-256- 具有正确密钥长度的CBC。' code>  p> 
  div>

I have fixed that issue with running command: php artisan config:cache. It was problem because of Laravel can't read .env file sometimes...

答

It seems your database connection is being closed. Using following code you can keep you connection alive after each image upload.

DB::reconnect();

答

This could be a problem with the Laravel app key. Try executing these two commands in the following order using the command line from your projects root directory:

php artisan key:generate
php artisan config:clear

You can also try making sure that in your config/app.php file you have the following and try to clear the config again:

'cipher' => 'AES-128-CBC',
