I need to submit a form to a website (http://www.itu.int/online/mms/mars/ship_search.sh) and I use the following code:
$postdata = http_build_query(
array(
'sh_mmsi' => '246709000'
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://www.itu.int/online/mms/mars/ship_search.sh', false, $context);
For some reason is not triggering the search query. If I hit the Submit button in the URL address http://www.itu.int/online/mms/mars/ship_search.sh?sh_mmsi=246709000, then the results shows at the end. I wonder if the problem is that this website has two forms and I would need to specify which one to post to? If so, how should I do it?

I got a homework to retrieve the 2nd results page of http://wiki.webo-facto.com from a search post data. Like this:
$postdata = http_build_query(
array(
'q' => 'catalogue',
'submit' => 'searchbutton'
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://wiki.webo-facto.com/', false, $context);
No problem.
My sensei said that:"Once a search is done, the search criteria is stored in session. It is this session that makes navigation work".
Then, from the same script i add $_SESSION['post']=$postdata;
header('Location: getsecondpage.php')
All of this stored in poster.php .
Now Time to retrive the second page in getsecondpage.php:
session_start();
$postdata = $_SESSION['postdata'];
$opts2 = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context2 = stream_context_create($opts2);
$result2 = file_get_contents('http://wiki.webo-facto.com/resultspage-2.html', false, $context2);
echo $result2;
return the results of the 1st page that are not what i want.
Your suggestion will be very helpful.
Notice: that i have also start the session from poster.php.(code not visible).
Sorry for my bad english, Im franco-saxon.
Your sensei is right, the search criteria is stored in session BUT in REMOTE SERVER SESSION. So what you have to do is "tell the server your session cookie" to be able to save and load it!
So for the first query we will do a POST with our search criteria AND telling the remote server our session name and id:
$opts = array('http' =>
array(
'method' => 'POST',
'header' => "Content-type: application/x-www-form-urlencoded\r\n" .
"Cookie: ".session_name()."=".session_id()."\r\n",
'content' => $postdata
)
);
And for the second one, server already stored our query in SESSION so we do not need to send it again. So we'll do a GET. Also telling server our session name and session id.
$opts2 = array('http' =>
array(
'method' => 'GET',
'header' => "Content-type: application/x-www-form-urlencoded\r\n" .
"Cookie: ".session_name()."=".session_id()."\r\n",
)
);
And that's it!
Is there an easy way to send out push notifications in PHP without using external libraries? Here is my current code. when executed the server gives a 400 UnauthorizedRegistration error. I do not care about how fast or efficient the process is, I am fine with sending one notification at a time.
My PHP code is:
<?php
ini_set("display_errors","1");
$endpoint = "https://fcm.googleapis.com/fcm/send/fImmyvrGiSo:APA91bFg8A4N4GLmJMhouxPfw_R3ocv44uBaNkZu_JMVjAvueISJUJTQROpVxlBnX8PIeJGwE5s1pvLAldtcW-z6WzZ0Ixus2fc3jUADGbJ2L8kAdMv56S5cSmKMsFmPwDsdd2MoCrHC";
$postdata = http_build_query(
array(
"p256dh" => "BAHBGTIPl7M1v8Ui7EaNVlauLmi_jEJOreCQ3YTRu_nWgF4k8nwP5rewGWO86-3wP8yZ86GoKjHQpK_0sls05FI=",
"auth" => "V08681gA2Gs_2x_UNFCN0g=="
)
);
$opts = array('http' =>
array(
'ignore_errors' => true,
'method' => 'POST',
'header' => 'Content-type: application/json',
'content' => $postdata
)
);
$context = stream_context_create($opts);
// here file_get_contents is used to send a POST request
$result = file_get_contents($endpoint, false, $context);
echo $result;
?>
My push subscription is:
{"endpoint":"https://fcm.googleapis.com/fcm/send/dcgCC59wHCE:APA91bHEzFoal6MXgXWt16aSdGHFAeS7D4vre99pCvzU_QWK22YFkmYdUQ5OmiLmUUbuhyiFEDHg61TrpllZ-TcaSgqXXOIcyTUf_0I-ngZ--aH2OFnEIrB2eI-ZRiArHD5LVAAz1EiM","expirationTime":null,"keys":{"p256dh":"BAHBGTIPl7M1v8Ui7EaNVlauLmi_jEJOreCQ3YTRu_nWgF4k8nwP5rewGWO86-3wP8yZ86GoKjHQpK_0sls05FI=","auth":"V08681gA2Gs_2x_UNFCN0g=="}}
I am trying to get the content (text) from a website where I am a member, I found a plenty of examples of how to do this using cURL to login and get the context, however I am not sure how to handle with the redirection after I get log into the website. The result that I got from the code below is the login form (Example #1 here). I am wondering if I have no access is this really possible to do?
$postdata = http_build_query(
array(
'Account' => 'myaccount',
'Password' => 'mypass'
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://www.website.php/login.php', false,
$context);
After the login successful what I expect is to get the text from the redirected url which looks like http://www.website.php/other.php
I've been looking for a solution for such a long time for my issue.
But i just can't find any solutions and i'm not sure what exactly to search for.
I'll explain my problem here.
Currently i have this PHP script which works perfect and sends a successfully request and receives the respond.
<?php
$url = 'http://example.nl/index.php';
$data = array('url' => 'http://www.myip.nl/', 'verkort' => 'Verkort URL');
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);
?>
But i really need help with sending a request with the following content:
See screenshot: http://i.imgur.com/VgedJes.png
I need to add the 3 headers and i'm not sure how to tell a field/value is empty as you can see in the screenshot.
I just can't figure out how to do this.
I would really appreciate it if someone could help me out with this!
To Add Header :
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\nX-Requested-With: XmlHttpRequest",
'method' => 'POST',
'content' => http_build_query($data),
),
);
Keep in mind that X-Requested-Header can only be interpreted by your PHP application
To send a parameter with an empty value you can do as follow
$data = array('url' => 'http://www.myip.nl/', 'verkort' => 'Verkort URL', 'notMandatoryParam' => '');
Also in your PHP code, you must do a verification : if(empty($_POST['notMandatoryParam'])) {/*SKIP ME*/}
Hi I'm trying to send post values using a PHP script to an external website and get the result. My code is as follows
$postdata = http_build_query(
array(
'drpservice' => 091,
'drpdirection' => 1,
'drpbusstop' => 18051
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents($url, false, $context);
echo $result;
However, it won't return the required results unless I can manage to send in the hidden _VIEWSTATE value.
Anyone able to help?
You need to first get the form page using a GET request, and then you can parse the page to get the _VIEWSTATE value using a regular expression.
Then when doing the POST pass the value you got for it.
