i have a hosted script somewhere that only accept POST request.
example, some.hosted/script.php
how can i setup another simple php that can accept GET request and then POST it to the hosted script.
so that i can put up a link like this: other.site/post2hostedscript.php?postthis=data
and then it POST postthis=data to the hosted script.
tnx
edit:
post2hostedscript.php do not give any result.
the result will go directly to some.hosted/script.php
just as if the user POST directly at the hosted script.
Your post2hostedscript.php will have to :
Fetch all parameters received as GET
Construct a POST query
Send it
And, probably, return the result of that POST request.
This can probably be done using curl, for instance ; something like this should get you started :
$queryString = $_SERVER['QUERY_STRING'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.othersite.com/post2hostedscript.php");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $queryString);
curl_exec($ch);
curl_close($ch);
For a list of options that can be used with curl, you can take a look at the page of curl_setopt.
Here, you'll have to use, at least :
CURLOPT_POST : as you want to send a POST request, and not a GET
CURLOPT_RETURNTRANSFER : depending on whether you want curl_exec to return the result of the request, or to just output it.
CURLOPT_POSTFIELDS : The data that will be posted -- i.e. what you have in the query string of your incoming request.
And note that the response from the POST request might include some interesting HTTP header -- if needed, you'll have to fetch them (see the CURLOPT_HEADER option), and re-send the interesting ones in your own response (see the header function).
Take a look at the "curl" functions, they provide everything you need.
You might consider replacing all instances of $_POST in the old script to $_REQUEST, which will result in it accepting both GET and POST alike.

I need to send a GET request to remote server with xml parameters.
example:
https://url.com/test.jsp?<xml></xml>
how to do it?
I tried to do with cURL, but the certificate error. Also tried to disable checking but to no avail.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
any idea? is it possible to do this using the file_get_contents() ?
cURL uses GET by default, and normally you'd use GET when, well, getting something from the server. As opposed to POST used to post data to a sever.
You can pass in your parameters as you would normally when using GET.
https://url.com/test.jsp?someXmlData=data&someOtherXmlData=someOtherData
You could used file_gets_content as long as you know the url from which you want to get the data.
Other people have already asked how to do this from perl, java, bash, etc. but I need to do it in PHP, and I don't see any question already asked relating specifically to (or with answers for) PHP.
My code:
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
This doesn't work. The destination site has print_r($_GET); print_r($_POST);, so when I examine the $result I should be able to see the fields that are being sent. However, the $_POST array is empty - I only see the get variables. If I remove the ?... query string from the $url, then the POST array is populated correctly. But now I don't have the GET params. How do I do this?
My specific case is, I need to send too much data to fit it in the query string, but I can't send it all as POST because the site I want to submit to is selecting a handler for the posted data based on a variable in the GET string. I can try and have that changed, but ideally I would like to be able to send both get and post data in the same query.
# GET query goes in the URL you're hitting
$ch = curl_init('http://example.com/script.php?query=parameter');
# POST fields go here.
curl_setopt($ch, CURLOPT_POSTFIELDS, array('post' => 'parameter', 'values' => 'go here'));
PHP itself wouldn't decide to ignore the GET parameters if a POST is performed. It'll populate $_GET regardless of what kind of http verb was used to load the page - if there's query parameters in the URL, they'll go into $_GET.
If you're not getting $_POST and $_GET with this, then something is causing a redirect or otherwise killing something. e.g. have you check $_SERVER['REQUEST_METHOD'] to see if your code is actually running as a POST? PHP won't populate $_POST if a post wasn't actually performed. You may have sent a post to the server, but that doesn't mean your code will actually be executed under a POST regime - e.g. a mod_rewrite redirect.
Since you have FOLLOW_REDIRECT turned on, you're simply ASSUMING you're actually getting a post when your code executes.
i don't know maybe you already have but is your $url has the desired get parameters? Like:
$url = "http://example.com/index.php?param1=value1¶m2=value2";
I am attempting to send a PUT request using PHP and curl and my query parameters do not seem to be making it to the API. The logs verify that the request is coming in as a PUT but the parameters are not making it. I've followed every example I could find on the internet that describes how to build the query parameters building it manually and using the http_build_query function. I then add the parameters using the CURLOPT_POSTFIELDS value. Am I missing something needed for query params with a PUT request?
Unlike the POST request, the PUT request requires to specify the Content-Length that you are going to send to the server. Here is an example:
// data to be sent
$post_data = "...soem data";
// so that you get response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// this is must for doing PUT
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Length: ' . strlen($post_data)));
// Doing PUT
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data );
If you still have problem after this, run the curl by enabling the verbose mode and it will show you the debug msg on curl's operation:
curl_setopt($ch, CURLOPT_VERBOSE, true);
I have an application that interacts with an outside API. When the remote serve posts a request containing specific status, I need to re-send the entire contents of that post to a different application through an external URL.
Is it possible to take the entire $_REQUEST and re-post it else where, or do I have to iterate through $_REQUEST and build a new array for posting where I need to?
$_REQUEST is an array. So yes you can post it where you need to. Just use cURL
If I correctly understand your question you're able to do it with CURL:
$ch = curl_init("http://sitename.com/");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "field1=value1&field2=value2");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
where "field1=value1&field2=value2" is replaced with your args
Also you're able to get result of how operation is completed:
after $result = curl_exec($ch); use:
$result_info = curl_getinfo($ch);
now in $result_info['http_code'] is placed HTTP CODE. If it's 200 then SUCCESS (of course the code might be different in some cases - e.g. when it's artificially configured to another code)
you should distinct between $_POST and $_GET values.
$_REQUEST represents all values that are coming by GET and POST, if one key is set in $_POST and $_GET value from $_POST have precedence when getting saved to the $_REQUEST array.
append everything that comes via $_GET to the URL and send everything from $_POST in the request body.
Using $HTTP_RAW_POST_DATA can save the overhead of reencoding, if both segements are a POST method
Lookup CURL, this should be rather easy:
http://davidwalsh.name/execute-http-post-php-curl
I would use the cURL extension.
Hi I am new to php and want to know some alternate function for the header('location:mysit.php');
I am in a scenario that I am sending the request like this:
header('Location: http://localhost/(some external site).php'&?var='test')
something like this but what I wanna do is that I want to send values of variables to the external site but I actually dont want that page to pop out.
I mean variables should be sent to some external site/page but on screen I want to be redirected to my login page. But seemingly I dont know any alternative please guide me. Thx.
You are searching for PHP cUrl:
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
Set the location header to the place you actually want to redirect the browser to and use something like cURL to make an HTTP request to the remote site.
The way you usually would do that is by sending those parameters by cURL, parse the return values and use them however you need.
By using cURL you can pass POST and GET variables to any URL.
Like so:
$ch = curl_init('http://example.org/?aVariable=theValue');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
Now, in $result you have the response from the URL passed to curl_init().
If you need to post data, the code needs a little more:
$ch = curl_init('http://example.org/page_to_post_to.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'variable1=value1&variable2=value2');
$result = curl_exec($ch);
curl_close($ch);
Again, the result from your POST reqeust is saved to $result.
You could connect to another URL in the background in numerous ways. There's cURL ( http://php.net/curl - already mentioned here in previous comments ), there's fopen ( http://php.net/manual/en/function.fopen.php ), there's fsockopen ( http://php.net/manual/en/function.fsockopen.php - little more advanced )
