Php 如何在laravel上用一种方法同时上传两个文件夹中的文件？

我使用的是laravel 5.6

我想一次上传两个文件夹中的文件。因此，如果图像成功上传到产品文件夹中，我希望图像也上传到thumbs文件夹中

我试着这样：

public function uploadImage($file)   
{
    if($file) {
        $fileName = str_random(40) . '.' . $file->guessClientExtension();
    }

    $destinationPath = storage_path() . DIRECTORY_SEPARATOR . 'app' . DIRECTORY_SEPARATOR . 'public' . DIRECTORY_SEPARATOR . 'product';

    if(!File::exists($destinationPath)) {
        File::makeDirectory($destinationPath, 0755, true);
    }

    $file->move($destinationPath, $fileName);

    $destinationPathThumb = storage_path() . DIRECTORY_SEPARATOR . 'app' . DIRECTORY_SEPARATOR . 'public' . DIRECTORY_SEPARATOR . 'product' . DIRECTORY_SEPARATOR . 'thumb';

    if(!File::exists($destinationPathThumb)) {
        File::makeDirectory($destinationPathThumb, 0755, true);
    }

    $image_resize = Image::make($file->getRealPath());  
    $image_resize->resize(300, 300);
    $image_resize->save($destinationPathThumb . DIRECTORY_SEPARATOR . $fileName);

    return $fileName;
}

$file = $file->move($destinationPath, $fileName);

如果代码运行，则只需将其成功上载到产品文件夹中即可。它没有上传到thumbs文件夹中

存在如下错误：

public function uploadImage($file)   
{
    if($file) {
        $fileName = str_random(40) . '.' . $file->guessClientExtension();
    }

    $destinationPath = storage_path() . DIRECTORY_SEPARATOR . 'app' . DIRECTORY_SEPARATOR . 'public' . DIRECTORY_SEPARATOR . 'product';

    if(!File::exists($destinationPath)) {
        File::makeDirectory($destinationPath, 0755, true);
    }

    $file->move($destinationPath, $fileName);

    $destinationPathThumb = storage_path() . DIRECTORY_SEPARATOR . 'app' . DIRECTORY_SEPARATOR . 'public' . DIRECTORY_SEPARATOR . 'product' . DIRECTORY_SEPARATOR . 'thumb';

    if(!File::exists($destinationPathThumb)) {
        File::makeDirectory($destinationPathThumb, 0755, true);
    }

    $image_resize = Image::make($file->getRealPath());  
    $image_resize->resize(300, 300);
    $image_resize->save($destinationPathThumb . DIRECTORY_SEPARATOR . $fileName);

    return $fileName;
}

$file = $file->move($destinationPath, $fileName);

异常干预\Image\exception\NotReadableException

我尝试运行以下代码：

public function uploadImage($file) 
{
    if($file) {
        $fileName = str_random(40) . '.' . $file->guessClientExtension();
    }
    $destinationPathThumb = storage_path() . DIRECTORY_SEPARATOR . 'app' . DIRECTORY_SEPARATOR . 'public' . DIRECTORY_SEPARATOR . 'product' . DIRECTORY_SEPARATOR . 'thumb';

    if(!File::exists($destinationPathThumb)) {
        File::makeDirectory($destinationPathThumb, 0755, true);
    }
    $image_resize = Image::make($file->getRealPath());  
    $image_resize->resize(300, 300);
    $image_resize->save($destinationPathThumb . DIRECTORY_SEPARATOR . $fileName);
    return $fileName;
}

所以我删除了要上传到产品文件夹中的代码。我试过了，效果很好。它成功上传到thumbs文件夹

所以我认为在一个过程中，它只上传到一个文件夹中

是否有其他方法可以在2个文件夹上上载

您首先上载临时文件，该文件将在您将其保存到磁盘上后被删除，这就是为什么您不能重复使用它的原因。您将获取保存的图像并对其进行大小调整，然后使用其他名称保存它：

public function uploadImage($file) 
{
...
$file->move($destinationPath, $fileName);
//$file here doesn't exist anymore, hence it can't be read
...
$uploadedFile = Storage::get($destinationPath . DIRECTORY_SEPARATOR . $filename);
$image_resize = Image::make($uploadedFile);  
$image_resize->resize(300, 300);
$image_resize->save($destinationPathThumb . DIRECTORY_SEPARATOR . $fileName);

return $fileName;
}

我找到了解决办法

我试着这样：

public function uploadImage($file)   
{
    if($file) {
        $fileName = str_random(40) . '.' . $file->guessClientExtension();
    }

    $destinationPath = storage_path() . DIRECTORY_SEPARATOR . 'app' . DIRECTORY_SEPARATOR . 'public' . DIRECTORY_SEPARATOR . 'product';

    if(!File::exists($destinationPath)) {
        File::makeDirectory($destinationPath, 0755, true);
    }

    $file->move($destinationPath, $fileName);

    $destinationPathThumb = storage_path() . DIRECTORY_SEPARATOR . 'app' . DIRECTORY_SEPARATOR . 'public' . DIRECTORY_SEPARATOR . 'product' . DIRECTORY_SEPARATOR . 'thumb';

    if(!File::exists($destinationPathThumb)) {
        File::makeDirectory($destinationPathThumb, 0755, true);
    }

    $image_resize = Image::make($file->getRealPath());  
    $image_resize->resize(300, 300);
    $image_resize->save($destinationPathThumb . DIRECTORY_SEPARATOR . $fileName);

    return $fileName;
}

$file = $file->move($destinationPath, $fileName);

它在保存$file后工作

，然后使用Storage:：get检索保存的文件，而不是临时文件$file@NikolaGavric试着用代码回答这个问题。让我来clearer@SuccessMan您的http请求post方法在哪里？@Sagar Gautam在控制器上。我上面的代码放在repositoriesEh好的，这样做很好，你在使用设计模式吗？您找到解决方案了吗？存在类似这样的错误：找不到类“App\Repositories\Storage”如果您花一分钟阅读，您可以看到您必须使用light\Support\Facades\Storage；仍然存在错误。错误：message/home/vagrant/code/my-app/storage/app/public/product/gckx3YQrbc8CnKMaXjlpjy9FnejYpbjKetMHXKGN.jpeg。异常\Contracts\Filesystem\FileNotFoundException
