Why is sometimes the picture that comes through curl not complete?

Question

PHP

request

$file = new \CURLFile($dir, 'image/jpg', $name);
//        dd($file, $target_url);
        set_time_limit(0);
        $printname = 'print_'.$name;
        $handle = fopen($printname,'w+');

        $ch = curl_init($target_url);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, [
            'file' => $file
        ]);
        curl_setopt($ch, CURLOPT_AUTOREFERER, true);

//        curl_setopt($ch,CURLOPT_TIMEOUT, 600);
        curl_setopt($ch, CURLOPT_FILE, $handle);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($ch, CURLOPT_ENCODING, "");
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        $raw=curl_exec($ch);
        $status = curl_getinfo($ch,  CURLINFO_RESPONSE_CODE);
        curl_close($ch);
        if($status === 200)
        {
            fwrite($handle, $raw);
            fclose($handle);
        }
        else
        {
            fclose($handle);
            dd('Err', $status);
        }

the picture that comes has a large weight of about 10mb and sometimes it seems that it cannot save it to the end


, but it looks like this in html (like the floor


of the picture) below the original sometimes the picture is normal

Answer 1

set a longer timeout, corny not pumping

Answer 2

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); 
curl_setopt($ch, CURLOPT_TIMEOUT, 0);
