为什么file_get_contents（$ url）或file_get_contents（urlencode（$ url））返回http请求失败

Question

when i use library intervention/image in laravel 4, with piece of code $image = Image::make($url) i meet error:

file_get_contents(http://ticket.at-newyork.com/image/tenboudai/rockfeller-top.jpg): failed to open stream: HTTP request failed! HTTP/1.1 410 Gone

I have researched many solution on stackoverflow and try it ex : use urlencode but i have another error :

file_get_contents(http%3A%2F%2Fticket.at-newyork.com%2Fimage%2Ftenboudai%2Frockfeller-top.jpg): failed to open stream: No such file or directory

Please don't suggest me use curl, because file_get_contents() is code in library and i can't change. Thank you

Answer 1

domain ticket.at-newyork.com need user-agent header in request to get content remotely. have a look on below solution it works for me.

$opts = array(
    'http'=>array(
        'method'=>"GET",
        'header'=>"Host: ticket.at-newyork.com\r\n" .
            "User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.80 Safari/537.36"
    )
);

$context = stream_context_create($opts);

$data = file_get_contents('http://ticket.at-newyork.com/image/tenboudai/rockfeller-top.jpg', false, $context);
file_put_contents('test.jpg', $data);

you can also use curl by setting CURLOPT_USERAGENT

Answer 2

This is my solution that help resolve it. Instead pass url in param, i use cURL in controller to get binary image data and pass it to param, this is my code:

    curl_handle = curl_init();
    curl_setopt($curl_handle, CURLOPT_URL,$url);
    curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
    curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl_handle, CURLOPT_USERAGENT, 'Vivo app');
    $query = curl_exec($curl_handle);
    curl_close($curl_handle);

    try {
        $image = Image::make($query)->save($destinationPath . $img_name);
