file_get_contents无法打开流：HTTP请求失败！ HTTP / 1.1 500内部服务器错误

Question

I'm retrieving and saving images from a external source to my webserver by URL's. Unfortaley sometimes I get the following error: failed to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error.

When I visit the given url with my browser the image is shown and valid. The url:

http://****.com/00/s/NTgwWDcyNg==/z/7LEAAMXQVT9TCcxx/$_85.JPG

The code which I use:

$opts = array('http'=>array('header' => "User-Agent:Mozilla/5.0 (Windows NT 6.2) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.75 Safari/537.1
", 'timeout' => "360"));
$context = stream_context_create($opts);                                         
$imageString = file_get_contents(urldecode(urlencode($filename)), false, $context);                                            
$save = file_put_contents(dirname(dirname(__FILE__)) . '/tmp/' . $id . '_' . $sequenceNumber . '.jpg', $imageString);

Anyone has a idea why I get a 500 error?

Answer 1

The following answer worked for me: PHP file_get_contents 500 Internal Server error

$opts = array('http' => array('header' => "User-Agent:MyAgent/1.0
"));
$context = stream_context_create($opts);
$header = file_get_contents('https://www.example.com', FALSE, $context);
