I have a html page which sends a get request to php.
This is the code snippet in the php file
<?php
// Create a stream
$opts = array(
'http'=>array(
'method'=>'GET',
)
);
$context = stream_context_create($opts);
//echo("http://services.my511.org/Transit2.0/GetNextDeparturesByStopName.aspx?token={$_GET['token']}&agencyName={$_GET['agency']}&stopName={$_GET['stopname']}");
// Open the file using the HTTP headers set above
$file = file_get_contents("http://services.my511.org/Transit2.0/GetNextDeparturesByStopName.aspx?token={$_GET['token']}&agencyName={$_GET['agency']}&stopName={$_GET['stopname']}", false, $context);
//$file = file_get_contents("http://services.my511.org/Transit2.0/GetNextDeparturesByStopName.aspx?token=123-456-789&agencyName=SF-MUNI&stopName=The%20Embarcadero%20and%20Folsom%20St", false, $context);
echo(json_encode(simplexml_load_string($file)));
?>
Developer Console Output :
Warning: file_get_contents(http://services.my511.org/Transit2.0/GetNextDeparturesByStopName.aspx?token=123-456-789&agencyName=BART&stopName=Powell St. (SF)): failed to open stream: HTTP request failed! HTTP/1.1 400 BAD_REQUEST
As you can see from the developer console output, in the url request sent there are BART&stopName amp;amp; being inserted in the url which I'm not doing. The request fails due to this. Any solution around this?
Try the below code, this will make sure that you're stuff is properly URI encoded.
$params = [
'token' => $_GET['token'],
'agencyName' => $_GET['agency'],
'stopName' => $_GET['stopname']
];
$file = file_get_contents(sprintf("http://services.my511.org/Transit2.0/GetNextDeparturesByStopName.aspx?%s", http_build_query($params));
echo(json_encode(simplexml_load_string($file)));
Try this one:
$data = array('token'=>$_GET['token'],
'stopname'=>$_GET['stopname'],
'agency'=>$_GET['agency'],
);
$url = "http://services.my511.org/Transit2.0/GetNextDeparturesByStopName.aspx?".$data;
$file = file_get_contents($url, false, $context);
echo(json_encode(simplexml_load_string($file)));
Note: I have modified my answer base on your comment.
You can try this way to clean out the url:
<?php
// Create a stream
$opts = array(
'http'=>array(
'method'=>'GET',
)
);
$context = stream_context_create($opts);
$url= "http://services.my511.org/Transit2.0/GetNextDeparturesByStopName.aspx?";
$query = array(
"token" =>$_GET['token'],
"agencyName"=>$_GET['agency'],
"stopName"=>$_GET['stopname']
);
$url = $url.http_build_query($query);
$url = rawurldecode($url);
print_r($url);
$file = file_get_contents($url, false, $context);
echo(json_encode(simplexml_load_string($file)));
?>

I’ve been trying to access this particular REST service from a PHP page I’ve created on our server. I narrowed the problem down to these two lines. So my PHP page looks like this:
$websiteUrl = "https://www.doofootball.com/";
$dom = file_get_html($websiteUrl);
var_dump($dom);
enter image description here
I remember having a similar problem with simple_html_dom. Suddenly it didn't work any longer without passing a context variable. I don't recall where I found this solution but it has been working for quite some time now. Just try this please and let me know whether this resolves your problem.
$context = stream_context_create(
array(
// 'http' => array(
// 'follow_location' => false
// ),
'ssl' => array(
"verify_peer"=>false,
"verify_peer_name"=>false,
),
)
);
$websiteUrl = "https://www.doofootball.com/";
$dom = file_get_html($websiteUrl, false, $context);
file_get_html expects these parameters:
function file_get_html(
$url,
$use_include_path = false,
$context = null,
$offset = 0,
$maxLen = -1,
$lowercase = true,
$forceTagsClosed = true,
$target_charset = DEFAULT_TARGET_CHARSET,
$stripRN = true,
$defaultBRText = DEFAULT_BR_TEXT,
$defaultSpanText = DEFAULT_SPAN_TEXT)
Don't remember why I commented out the lines with "follow_location" ... You'll figure it out. Good luck!
I'm attempting a GET request using SSL and basic auth using the file_get_contents function:
$username = "XXXXXXXXXX";
$password = "XXXXXXXXXX";
$url = "https://stream.watsonplatform.net/authorization/api/v1/token?url=https://stream.watsonplatform.net/speech-to-text/api";
$context = stream_context_create(array("http" => array("header" => "Authorization: Basic " . base64_encode("$username:$password"))));
$data = file_get_contents($url, false, $context);
echo $data;
Here's the error message I get:
Warning: file_get_contents(https://stream.watsonplatform.net/authorization/api/v1/token?url=https://stream.watsonplatform.net/speech-to-text/api): failed to open stream: HTTP request failed! HTTP/1.0 500 Server Error...
I've already confirmed that openssl is enabled:
And we might as well get this out of the way up-front:
Why don't you just use cURL?
I could. But I also want to figure out why file_get_contents isn't working. I like the relative simplicity of file_get_contents. Call me crazy.
Curiosity is a good thing so it's cool to dig this problem without falling back to cURL before fixing this problem.
<?php
$username = "XXXXXXXXXX";
$password = "XXXXXXXXXX";
$url = "https://stream.watsonplatform.net/authorization/api/v1/token?url=https://stream.watsonplatform.net/speech-to-text/api";
$context = stream_context_create(array(
"http" => array(
"header" => "Authorization: Basic " . base64_encode("$username:$password"),
"protocol_version" => 1.1, //IMPORTANT IS HERE
)));
$data = file_get_contents($url, false, $context);
echo $data;
The fact is the server does not support HTTP/1.0. So you haven't any problem with SSL/TLS nor with your user agent. It is just the server that support HTTP from 1.1.
As said in the stream_context_create documentation the default protocol_version used in stream_context_create is 1.0. That's why you got an error 500.
EDIT : My bad, don't see this is not curl. Try with this
$username = "XXXXXXXXXX";
$password = "XXXXXXXXXX";
$url = "https://stream.watsonplatform.net/authorization/api/v1/token?url=https://stream.watsonplatform.net/speech-to-text/api";
$context = stream_context_create(array(
"http" => array("header" => "Authorization: Basic " . base64_encode("$username:$password")),
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false,
)));
$data = file_get_contents($url, false, $context);
echo $data;
I wanted to send a post request to pilosa database. The request is like this -
curl localhost:10101/index/user/query
-X POST
-d 'Bitmap(frame="language", id=5)'.
How can i send the following request through php ?
Link for referrence : https://www.pilosa.com/docs/api-reference/
If you don't have the php curl library available to you, you can query Pilosa with php's file_get_contents which is part of core php. The following php script should perform your example query:
<?php
$url = 'http://localhost:10101/index/user/query';
$data = 'Bitmap(frame="language", id=5)';
$options = array(
'http' => array(
'method' => 'POST',
'content' => $data
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);
?>
The Pilosa HTTP API documentation can be found at: https://www.pilosa.com/docs/api-reference/
I have a very simple script that works perfectly on most sites but not the main site I want it to work with - the code below accesses a sample site perfectly. However when I use it on a site I want to access http://www.livescore.com I get an error
This works.
<?php
$url = "http://www.cambodia.me.uk";
$page = file_get_contents($url);
$outfile = "contents.html";
file_put_contents($outfile, $page);
?>
This does not work.....
<?php
$url = "http://www.livescore.com";
$page = file_get_contents($url);
$outfile = "contents.html";
file_put_contents($outfile, $page);
?>
and gives the following error
Warning: file_get_contents(http://www.livescore.com)
[function.file-get-contents]: failed to open stream: HTTP request
failed! HTTP/1.0 404 Not Found in C:\Program Files
(x86)\EasyPHP-5.3.8.1\www\Livescore\attempt-1-read-page.php on line 3
Thanks for any assistance
In common case you can just say to file_get_contents to follow redirects:
$context = stream_context_create(
array(
'http' => array(
'follow_location' => true
)
)
);
$html = file_get_contents('http://www.example.com/', false, $context);
This site tries to analyze User-agent http header, and fails if it's not found. Try to add some user-agent header:
<?php
$context = stream_context_create(
array(
'http' => array(
'header' => "User-agent: chrome",
'ignore_errors' => true,
'follow_location' => true
)
)
);
$html = file_get_contents('http://www.livescore.com/', false, $context);
echo substr($html, 0, 200)."\n";
Most likely www.livescore.com is doing a hidden redirect which file_get_contents is too basic to catch.
Do you have lynx installed on your server?
$page= shell_exec("lynx -source 'http://www.livescore.com'");
lynx is a full browser and can 'bypass' certain redirects.
I have a HTML page that has to call a PHP on another domain. The "Same-Origin-Rule" of most browsers prohibits that call. So I want to call a PHP on my domain to call a PHP on the target domain. I want to avoid cURL so I decided to use fopen in that pass-through PHP using $context:
$params = array('http' => array('method'=>'POST',
'header'=>'Content-type: application/json',
'content'=>json_encode($_POST)));
$ctx = stream_context_create($params);
$fp = fopen('https://other_domain.com/test.php', 'rb', false, $ctx);
$response = stream_get_contents($fp);
echo $response;
But the incoming $_POST in test.php seems to be empty. Any ideas?
Try to build params with http_build_query()
$postdata = http_build_query(
array(
'json' => json_encode($_POST),
)
);
and then
$params = array('http' => array('method'=>'POST',
'header'=>'Content-type: application/x-www-form-urlencoded',
'content'=> $postdata));
On the other site get it via $_POST['json']
Unless you have a server that supports application/json as a POST content type, your code isn't going to work: HTTP servers expect POST data to always be one of application/x-www-form-encoded or multipart/form-data. You need to rewrite your code to send the POST data in one of the supported types.
I managed it this way:
$postData = file_get_contents('php://input');
$params = array('http' => array('method'=>'POST',
'header'=>'Content-type: application/x-www-form-urlencoded',
'content'=>$postData));
$ctx = stream_context_create($params);
$url = 'https://other_domain.com/test.php';
$fp = fopen($url, 'rb', false, $ctx);
$response = stream_get_contents($fp);
echo $response;
This easily hands trough all incoming POST data and also forwards any responses. Thanks for all your posts!
