I try to catch error when the requested url does not exist in my application when I use requestAction($url);
with try-catch block, requested wrongs url continue to be loaded;
Please tell me if there is an other solution to test if the url exist, or if the file exist in cakephp dir (my url can be composed of a plugin name).
my actual code:
$url = $appliUrl . $cron['Cron']['plugin'] . '/'. $cron['Cron']['controller'] . '/' . $cron['Cron']['action'];
if (!empty($cron['Cron']['params'])) {
$params = explode(',', $cron['Cron']['params']);
foreach ($params as $param)
$url .= '/' . $param;
}
try{
$output = $this->requestAction($url);
}catch (Exception $e){
$output = "error in the url : ".$url;
}
You can use a variety of methods to accomplish this. In this example, use cURL.
function url_exists($url) {
if (!$fp = curl_init($url)) return false;
return true;
}
Then you can wrap your $output in an if block checking for the url.
if (url_exists($url)) {
$output = $this->requestAction($url);
}
EDIT
Make sure you put the function in a lib or your bootstrap for access. Don't just stick it in your controller like that :)
ANOTHER EDIT
<?php
$ch = curl_init('http://yoururl/');
curl_setopt($ch, CURLOPT_NOBODY, 1);
$c = curl_exec($ch);
echo curl_getinfo($ch, CURLINFO_HTTP_CODE);

Below is the code i have created so far, my goal is to use the youtube Search: list api to find streams for specific games and then publish how many streams there are for that game, I have a database for the game titles and this is my function below, my api link does work im just not able to get the Info.totalResults from it, any help would be great, Thank you for any help you can provide
function totalgamelist() {
global $wpdb;
$gamelistname = $wpdb->prefix . 'Games';
global $wpdb;
$getgames = $wpdb->get_results( 'SELECT * FROM '.$gamelistname , OBJECT );
if (empty($getgames)) {
//empty array
echo 'This is empty sorry!';
} else {
echo 'We Got Something!';
foreach ( $getgames as $getgame )
{
echo '<div class="gamename">'.$getgame->GameTitle;
$JSON = file_get_contents("https://www.googleapis.com/youtube/v3/search?part=snippet&eventType=live&type=video&videoCategoryId=20®ionCode=US&maxResults=50&q='.$getgame->GameTitle.'&key=[API KEY]");
$json_data = json_decode($JSON, true);
echo $json_data['totalResults'];
echo '</div>';
}
}
}
EDIT:
So with the help from johnh10, i was able to find out that it wasn't my ability to display the results although the echo johnh10 gave is correct :) it was also that my server was blocking access to the url i was asking to view. Below is the curl code i used to access the url, hope it helps others.
$urlgame = 'https://www.googleapis.com/youtube/v3/search?part=snippet&eventType=live&type=video&videoCategoryId=20®ionCode=US&maxResults=1&q='.$getgame->GameTitle.'&key=[API Key]';
$ch = curl_init($urlgame);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
$json_data = json_decode($data, true);
if (!empty($json_data)) {
$streamnumber = $json_data['pageInfo']['totalResults'];
echo ' Streams:'.$streamnumber;
} else {
echo ' Streams: No Streams Found';
}
echo $json_data['pageInfo']['totalResults'];
There is this new Export functionality developed on this application and I'm trying to test it using Behat/Mink.
The issue here is when I click on the export link, the data on the page gets exported in to a CSV and gets saved under /Downloads but I don't see any response code or anything on the page.
Is there a way I can export the CSV and navigate to the /Downloads folder to verify the file?
Assuming you are using the Selenium driver you could "click" on the link and $this->getSession()->wait(30) until the download is finished and then check the Downloads folder for the file.
That would be the simplest solution. Alternatively you can use a proxy, like BrowserMob, to watch all requests and then verify the response code. But that would be a really painful path for that alone.
The simplest way to check that the file is downloaded would be to define another step with a basic assertion.
/**
* #Then /^the file ".+" should be downloaded$/
*/
public function assertFileDownloaded($filename)
{
if (!file_exists('/download/dir/' . $filename)) {
throw new Exception();
}
}
This might be problematic in situations when you download a file with the same name and the browser saves it under a different name. As a solution you can add a #BeforeScenario hook to clear the list of the know files.
Another issue would be the download dir itself – it might be different for other users / machines. To fix that you could pass the download dir in your behat.yml as a argument to the context constructor, read the docs for that.
But the best approach would be to pass the configuration to the Selenium specifying the download dir to ensure it's always clear and you know exactly where to search. I am not certain how to do that, but from the quick googling it seems to be possible.

The basic idea is to copy the current session and do the request with Guzzle. After that you can check the response any way you like.
class FeatureContext extends \Behat\Behat\Context\BehatContext {
/**
* #When /^I try to download "([^"]*)"$/
*/
public function iTryToDownload($url)
{
$cookies = $this->getSession()->getDriver()->getWebDriverSession()->getCookie('PHPSESSID');
$cookie = new \Guzzle\Plugin\Cookie\Cookie();
$cookie->setName($cookies[0]['name']);
$cookie->setValue($cookies[0]['value']);
$cookie->setDomain($cookies[0]['domain']);
$jar = new \Guzzle\Plugin\Cookie\CookieJar\ArrayCookieJar();
$jar->add($cookie);
$client = new \Guzzle\Http\Client($this->getSession()->getCurrentUrl());
$client->addSubscriber(new \Guzzle\Plugin\Cookie\CookiePlugin($jar));
$request = $client->get($url);
$this->response = $request->send();
}
/**
* #Then /^I should see response status code "([^"]*)"$/
*/
public function iShouldSeeResponseStatusCode($statusCode)
{
$responseStatusCode = $this->response->getStatusCode();
if (!$responseStatusCode == intval($statusCode)) {
throw new \Exception(sprintf("Did not see response status code %s, but %s.", $statusCode, $responseStatusCode));
}
}
/**
* #Then /^I should see in the header "([^"]*)":"([^"]*)"$/
*/
public function iShouldSeeInTheHeader($header, $value)
{
$headers = $this->response->getHeaders();
if ($headers->get($header) != $value) {
throw new \Exception(sprintf("Did not see %s with value %s.", $header, $value));
}
}
}
Little modified iTryToDownload() function with using all cookies:
public function iTryToDownload($link) {
$elt = $this->getSession()->getPage()->findLink($link);
if($elt) {
$value = $elt->getAttribute('href');
$driver = $this->getSession()->getDriver();
if ($driver instanceof \Behat\Mink\Driver\Selenium2Driver) {
$ds = $driver->getWebDriverSession();
$cookies = $ds->getAllCookies();
} else {
throw new \InvalidArgumentException('Not Selenium2Driver');
}
$jar = new \Guzzle\Plugin\Cookie\CookieJar\ArrayCookieJar();
for ($i = 0; $i < count($cookies); $i++) {
$cookie = new \Guzzle\Plugin\Cookie\Cookie();
$cookie->setName($cookies[$i]['name']);
$cookie->setValue($cookies[$i]['value']);
$cookie->setDomain($cookies[$i]['domain']);
$jar->add($cookie);
}
$client = new \Guzzle\Http\Client($this->getSession()->getCurrentUrl());
$client->addSubscriber(new \Guzzle\Plugin\Cookie\CookiePlugin($jar));
$request = $client->get($value);
$this->response = $request->send();
} else {
throw new \InvalidArgumentException(sprintf('Could not evaluate: "%s"', $link));
}
}
In project we have problem that we have two servers: one with web drivers and browsers and second with selenium hub. As result we decide to use curl request for fetching headers. So I wrote function which would called in step definition. Below you can find a function which use a standard php functions: curl_init()
/**
* #param $request_url
* #param $userToken
* #return bool
* #throws Exception
*/
private function makeCurlRequestForDownloadCSV($request_url, $userToken)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$headers = [
'Content-Type: application/json',
"Authorization: Bearer {$userToken}"
];
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
$output .= "\n" . curl_error($ch);
curl_close($ch);
if ($output === false || $info['http_code'] != 200 || $info['content_type'] != "text/csv; charset=UTF-8") {
$output = "No cURL data returned for $request_url [" . $info['http_code'] . "]";
throw new Exception($output);
} else {
return true;
}
}
How you can see I have authorization by token. If you want to understand what headers you should use you should download file manual and look request and response in browser's tab network
I am trying to do force download using ZF2. Here is the snippet to my code
use Zend\Http\Request;
.....
public function downloadAction() {
$response = new Request();
$response->setHeaders(Request::fromString("Content-Type: application/octet-stream\r\nContent-Length: 9\r\nContent-Disposition: attachment; filename=\"ultimate_remedy_readme.txt\""));
}
now i am getting this error
/var/www/whowantsmymoney/vendor/zendframework/zendframework/library/Zend/Http/Request.php:88
Message:
A valid request line was not found in the provided string
Stack trace:
#0 /var/www/whowantsmymoney/module/Admin/src/Admin/Controller/LanguageController.php(93): Zend\Http\Request::fromString('Content-Type: a...')
This code should help you for a simple file download.
public function downloadAction() {
$fileName = 'somefile';
if(!is_file($fileName)) {
//do something
}
$fileContents = file_get_contents($fileName);
$response = $this->getResponse();
$response->setContent($fileContents);
$headers = $response->getHeaders();
$headers->clearHeaders()
->addHeaderLine('Content-Type', 'whatever your content type is')
->addHeaderLine('Content-Disposition', 'attachment; filename="' . $fileName . '"')
->addHeaderLine('Content-Length', strlen($fileContents));
return $this->response;
}
I imagine this code leaves a lot to be desired, but should work in simple cases, as was mine. I'm not sure how you might handle reading the file in chunks. Maybe somebody else could shed some light?
Edit - Sending streams
I've added this here for informational purposes. It is probably the better way to force downloads as it will use much less memory.
public function downloadAction() {
$fileName = 'somefile';
$response = new \Zend\Http\Response\Stream();
$response->setStream(fopen($fileName, 'r'));
$response->setStatusCode(200);
$headers = new \Zend\Http\Headers();
$headers->addHeaderLine('Content-Type', 'whatever your content type is')
->addHeaderLine('Content-Disposition', 'attachment; filename="' . $fileName . '"')
->addHeaderLine('Content-Length', filesize($fileName));
$response->setHeaders($headers);
return $response;
Thanks to #Aydin Hassan for response, but several important headers are missing in his answer. Be careful of that.
Full headers stack:
public function downloadAction() {
$file = 'path/to/file';
$response = new \Zend\Http\Response\Stream();
$response->setStream(fopen($file, 'r'));
$response->setStatusCode(200);
$response->setStreamName(basename($file));
$headers = new \Zend\Http\Headers();
$headers->addHeaders(array(
'Content-Disposition' => 'attachment; filename="' . basename($file) .'"',
'Content-Type' => 'application/octet-stream',
'Content-Length' => filesize($file),
'Expires' => '#0', // #0, because zf2 parses date as string to \DateTime() object
'Cache-Control' => 'must-revalidate',
'Pragma' => 'public'
));
$response->setHeaders($headers);
return $response;
}
I was using basic auth to send tweets from a server every time a song changed. Now they have blocked basic auth and I am not sure how to incorporate it. I have a server at home that updates an html file on the webserver and then calls the following script to tweet out from that file. Any ideas on how to accomplish this simply?
<?php
//====================================================
// CONFIGURATION

$username = '#####';
$password = '#####';
DEFINE(htmlfile, '/homec/public_html/site.com/twitter.html');
$stationURL = "http://www.site.com";
$maxLimit = "139";
$da="";
$f=#fopen(htmlfile, "r");
if ($f!=0)
{
$da=#fread($f, 4096);
fclose($f);
}
else
{
exit;
}
$da=str_replace("\r", "\n", $da);
$da=str_replace("\n\n", "\n", $da);
$d=explode("\n", $da);
$d[0]=trim($d[0], "|"); // title
$d[1]=trim($d[1], "|"); // artist
//====================================================
if ($d[0]=="" || $d[1]=="")
{
// IF WE COULD NOT GRAB THE ARTIST AND
// SONG TITLE FROM THE SAM-GENERATED HTML FILE,
// WE'LL BAIL OUT NOW WITHOUT SUBMITTING ANY TEXT
// TO TWITTER.
exit;
}
else
{
// SUCCESS IN GETTING ARTIST AND TITLE!
// WE'LL PROCEED WITH BUILDING A TEXT STRING TO SUBMIT TO TWITTER.
$message = urlencode('' . $d[1] . ' - ' . $d[0] . ' #bandradio #nowplaying ');
$stationURL = urlencode(' ' . $stationURL);
if ((strlen($message) + strlen($stationURL)) > $maxLimit)
{
// We have to truncate the artist-title string to make room for the station URL string.
$message = substr($message, 0, (($maxLimit - 2) - strlen($stationURL)));
$message .= ".." . $stationURL;
}
else
{
// No need to truncate, it all fits.
$message = $message . $stationURL;
}
} // if ($d[0]=="" || $d[1]=="")
//====================================================
// The twitter API address
$url = 'http://twitter.com/statuses/update.json';
// Set up and execute the curl process

curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);

Download the latest version of TwitterOAuth from http://github.com/abraham/twitteroauth/downloads Unpack the download and place the twitteroauth.php and OAuth.php files in the same directory as a file with the following code. Register an application at http://dev.twitter.com/apps and from your new apps details page click on "my access token" to get your access token. Fill the four required variables into the script below and you can then run it to post new tweets.
<?php
require_once('twitteroauth.php');
$connection = new TwitterOAuth('app consumer key', 'app consumer secret', 'my access token', 'my access token secret');
$connection->post('statuses/update', array('status' => 'text to be tweeted'));
I found the following code on here that I think does what I want, but it doesn't work:
$host = "www.example.com";
$path = "/path/to/script.php";
$data = "data1=value1&data2=value2";
$data = urlencode($data);
header("POST $path HTTP/1.1\r\n");
header("Host: $host\r\n");
header("Content-type: application/x-www-form-urlencoded\r\n");
header("Content-length: " . strlen($data) . "\r\n");
header("Connection: close\r\n\r\n");
header($data);
I'm looking to post form data without sending users to a middle page and then using JavaScript to redirect them. I also don't want to use GET so it isn't as easy to use the back button.
Is there something wrong with this code? Or is there a better method?
Edit I was thinking of what the header function would do. I was thinking I could get the browser to post back to the server with the data, but this isn't what it's meant to do. Instead, I found a way in my code to avoid the need for a post at all (not breaking and just continuing onto the next case within the switch).
The header function is used to send HTTP response headers back to the user (i.e. you cannot use it to create request headers.
May I ask why are you doing this? Why simulate a POST request when you can just right there and then act on the data someway? I'm assuming of course script.php resides on your server.
To create a POST request, open a up a TCP connection to the host using fsockopen(), then use fwrite() on the handler returned from fsockopen() with the same values you used in the header functions in the OP. Alternatively, you can use cURL.
The answer to this is very needed today because not everyone wants to use cURL to consume web services. Also PHP does allow for this using the following code
function get_info()
{
$post_data = array(
'test' => 'foobar',
'okay' => 'yes',
'number' => 2
);
// Send a request to example.com
$result = $this->post_request('http://www.example.com/', $post_data);
if ($result['status'] == 'ok'){
// Print headers
echo $result['header'];
echo '<hr />';
// print the result of the whole request:
echo $result['content'];
}
else {
echo 'A error occured: ' . $result['error'];
}
}
function post_request($url, $data, $referer='') {
// Convert the data array into URL Parameters like a=b&foo=bar etc.
$data = http_build_query($data);
// parse the given URL
$url = parse_url($url);
if ($url['scheme'] != 'http') {
die('Error: Only HTTP request are supported !');
}
// extract host and path:
$host = $url['host'];
$path = $url['path'];
// open a socket connection on port 80 - timeout: 30 sec
$fp = fsockopen($host, 80, $errno, $errstr, 30);
if ($fp){
// send the request headers:
fputs($fp, "POST $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
if ($referer != '')
fputs($fp, "Referer: $referer\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ". strlen($data) ."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data);
$result = '';
while(!feof($fp)) {
// receive the results of the request
$result .= fgets($fp, 128);
}
}
else {
return array(
'status' => 'err',
'error' => "$errstr ($errno)"
);
}
// close the socket connection:
fclose($fp);
// split the result header from the content
$result = explode("\r\n\r\n", $result, 2);
$header = isset($result[0]) ? $result[0] : '';
$content = isset($result[1]) ? $result[1] : '';
// return as structured array:
return array(
'status' => 'ok',
'header' => $header,
'content' => $content);
}
In addition to what Salaryman said, take a look at the classes in PEAR, there are HTTP request classes there that you can use even if you do not have the cURL extension installed in your PHP distribution.
There is a good class that does what you want. It can be downloaded at: http://sourceforge.net/projects/snoopy/
private function sendHttpRequest($host, $path, $query, $port=80){
header("POST $path HTTP/1.1\r\n" );
header("Host: $host\r\n" );
header("Content-type: application/x-www-form-urlencoded\r\n" );
header("Content-length: " . strlen($query) . "\r\n" );
header("Connection: close\r\n\r\n" );
header($query);
}
This will get you right away
