I am having problems calling a url from PHP code. I need to call a service using a query string from my PHP code. If I type the url into a browser, it works ok, but if I use file-get-contents() to make the call, I get:
Warning: file-get-contents(http://.... ) failed to open stream: HTTP request failed! HTTP/1.1 202 Accepted in ...
The code I am using is:
$query=file_get_contents('http://###.##.##.##/mp/get?mpsrc=http://mybucket.s3.amazonaws.com/11111.mpg&mpaction=convert format=flv');
echo($query);
Like I said - call from the browser and it works fine. Any suggestions?
I have also tried with another url such as:
$query=file_get_contents('http://www.youtube.com/watch?v=XiFrfeJ8dKM');
This works fine... could it be that the url I need to call has a second http://
in it?
This question is related to
php
api
query-string
file-get-contents
file_get_contents()
utilizes the fopen()
wrappers, therefore it is restricted from accessing URLs through the allow_url_fopen
option within php.ini.
You will either need to alter your php.ini to turn this option on or use an alternative method, namely cURL - by far the most popular and, to be honest, standard way to accomplish what you are trying to do.
<?php
$lurl=get_fcontent("http://ip2.cc/?api=cname&ip=84.228.229.81");
echo"cid:".$lurl[0]."<BR>";
function get_fcontent( $url, $javascript_loop = 0, $timeout = 5 ) {
$url = str_replace( "&", "&", urldecode(trim($url)) );
$cookie = tempnam ("/tmp", "CURLCOOKIE");
$ch = curl_init();
curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookie );
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
curl_setopt( $ch, CURLOPT_ENCODING, "" );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false ); # required for https urls
curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );
curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout );
curl_setopt( $ch, CURLOPT_MAXREDIRS, 10 );
$content = curl_exec( $ch );
$response = curl_getinfo( $ch );
curl_close ( $ch );
if ($response['http_code'] == 301 || $response['http_code'] == 302) {
ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1");
if ( $headers = get_headers($response['url']) ) {
foreach( $headers as $value ) {
if ( substr( strtolower($value), 0, 9 ) == "location:" )
return get_url( trim( substr( $value, 9, strlen($value) ) ) );
}
}
}
if ( ( preg_match("/>[[:space:]]+window\.location\.replace\('(.*)'\)/i", $content, $value) || preg_match("/>[[:space:]]+window\.location\=\"(.*)\"/i", $content, $value) ) && $javascript_loop < 5) {
return get_url( $value[1], $javascript_loop+1 );
} else {
return array( $content, $response );
}
}
?>
I'm not sure about the parameters(mpaction, format), if they are specified for the amazonaws page or ##.##.
Try to urlencode() the url.
You basically are required to send some information with the request.
Try this,
$opts = array('http'=>array('header' => "User-Agent:MyAgent/1.0\r\n"));
//Basically adding headers to the request
$context = stream_context_create($opts);
$html = file_get_contents($url,false,$context);
$html = htmlspecialchars($html);
This worked out for me
I notice that your URL has spaces in it. I think that usually is a bad thing. Try encoding the URL with
$my_url = urlencode("my url");
and then calling
file_get_contents($my_url);
and see if you have better luck.
I got a similar problem , I parsed the youtube url. The code is;
$json_is = "http://gdata.youtube.com/feeds/api/videos?q=".$this->video_url."&max-results=1&alt=json";
$video_info = json_decode ( file_get_contents ( $json_is ), true );
$video_title = is_array ( $video_info ) ? $video_info ['feed'] ['entry'] [0] ['title'] ['$t'] : '';
Then I realise that $this->video_url
include the whitespace. I solved that using trim($this->video_url)
.
Maybe it will help you . Good Luck
This is what worked for me... I did not use curl.
I was able to access a particular API url via browser, but when used in file_get_contents, it gave the error " failed to open stream".
Then, I modified the API URL that I wanted to call by encoding all double quotes with urlencoding and kept everything else untouched.
Sample format is given below:
$url = 'https://stackoverflow.com/questions'.urlencode('"'.$variable1.'"');
Then use
file_get_contents($url);
I got a similar problem.
Due to timeout !
Timeout can be indicated like this :
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => "POST",
'content' => http_build_query($data2),
'timeout' => 30,
),
);
$context = stream_context_create($options); $retour =
$retour = @file_get_contents("http://xxxxx.xxx/xxxx", false, $context);
$query=file_get_contents('http://###.##.##.##/mp/get?' . http_build_query(array('mpsrc' => 'http://mybucket.s3.amazonaws.com/11111.mpg&mpaction=convert format=flv')));
Use this
file_get_contents($my_url,null,null);
