Answer 1

使用curl为文件提供对PHP FILE的写入权限以存储内容。这可以通过三种方式完成：

如果您有终端访问权限，则使用chmod提供写入权限
如果您具有CPanel访问权限，则使用目录浏览器，然后通过更改文件属性提供对文件的写入权限。
您必须具有FTP访问权限并更改文件访问属性并提供写入权限。

Answer 2

不要使用卷曲。

如果您只需下载图片，请转到“file_get_contents”。这很简单：

$fileContents = file_get_contents("https://www.google.com/images/srpr/logo4w.png");
File::put('where/to/store/the/image.jpg', $fileContents);

Answer 3

function saveImageToFile($image_url,$output_filename)
{
    $ch = curl_init ($url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    $raw=curl_exec($ch);
    curl_close ($ch);
    if(file_exists($saveto))
    {
        unlink($saveto); //Saves over files
    }
    $fp = fopen($saveto,'x');
    fwrite($fp, $raw);
    fclose($fp);
}

Answer 4

你的问题很简单，我不知道别人怎么忽略它。这是Laravel特有的。您的$ dir变量返回HTTP资源标识符。您需要的是文件系统标识符。

对于laravel，将您的URL :: to（）更改为路径（“public”），告诉Laravel停止使用HTTP URI，而是将本地路径转到公用文件夹（/ your / laravel / setup / path / public /).

<强>码

$dir = path("public") . "img/products/";

$imgSrc = "an image on the web";

$file = fopen($dir . substr($imgSrc,strrpos("/",$imgSrc)+1), "wb");

$headers[] = 'Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg';              
$headers[] = 'Connection: Keep-Alive';         
$headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8';         
$user_agent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)';  

$ch = curl_init($imgSrc);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);         
curl_setopt($ch, CURLOPT_HEADER, 0);         
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent); 
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FILE, $file); // location to write to
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60);
$contents = curl_exec($ch);
$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
curl_close($ch);

if ($curl_errno > 0) 
{
    Log::write("CURL", "cURL Error (".$curl_errno."): ".$curl_error);
} 
else 
{
    Log::write("CURL", "Data received: " . $contents);
    fwrite($file,$contents);
    fclose($file);

}

return;

好的，最后让它全部正常工作，如果其他人试图做同样的事情，这里是代码！

我错过了这些部分：

    $dir = $_SERVER['DOCUMENT_ROOT'] . "/img/products/";

和

    fwrite($file,$contents);

所以这是我的最终代码......信任Sébastien指出我正确的方向。感谢。

        if($method == 'save')
        {
            $productId = Input::get('pId');
            $removeProductImages = DB::table('product_ref_images')->where('product_id', '=', $productId)->delete();

            $imagesData = Input::get('imageRefs');

            $dir = $_SERVER['DOCUMENT_ROOT'] . "/img/products/";

            $sortOrder = 0;

            for ($i=0; $i < count($imagesData); $i++) {

                $imgSrc = trim($imagesData[$i]['imgSrc']);
                $imgId = trim($imagesData[$i]['imgId']);

                $file = fopen($dir . basename($imgSrc), "wb");

                $headers[] = 'Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg';

                $curl_error = curl_error($ch);
                curl_close($ch);

                if ($curl_errno > 0) 
                {
                    Log::write("CURL", "cURL Error (".$curl_errno."): ".$curl_error);
                    break;
                } 
                else 
                {
                    fwrite($file,$contents);
                    fclose($file);

                    $imageIds = DB::table('product_ref_images')->order_by('image_id', 'desc')->first();

                    if($imageIds == null)
                    {
                        $imageIds = 0;

                        $imageIds = $imageIds->image_id;
                    }

                    $updateImages = DB::table('product_ref_images')
                        ->insert(array(
                            'image_id'          =>  $imageIds + 1,
                            'product_id'        =>  $productId,

删除此行：

 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

您将响应存储到文件中，而不是存储在返回变量中。否则，您必须自己保存（就像您在其他解决方案中所做的那样）。
