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.

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'm trying to send a special character, such as ñ, through a POST request in PHP. When I do it, it comes out as ñ, what is wrong and how do I fix it?
I'm sending and receiving the post request in PHP, here is what I use to send it:
$url = '<url>';
$data = array('key' => 'ñ');
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
echo $result;
Thanks in advance!
Try using this:
$data = array('key' => urlencode('ñ'));
And in the $url file:
$_POST['key']=urldecode($_POST['key']);
This is how I use to send special characters in GET and POST method with ajax, it must work for php too.
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 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'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*/}
