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 to automate uploading values to a remote server by php script.
The interface accepts only POST variables - NO GET variables.
Interface documentation (for form field names) looks like:
iegUsername: your username
iegPassword: your password
iegImportFile: The UTF-8 encoded plain text import file. The file data may optionally be zipped.
This means i have to POST TWO VARIABLES and ONE FILE.
I'm new in Curl therefore i started in PHP with this:
// create curl resource
$request = curl_init();
// Array with the fields names and values
$postData = array(
'iegUsername' => 'myusername',
'iegPassword' => 'mypassword',
'submit' => 'ok'
);
//add file support with: 'file' => '#' . realpath('example.txt')
// set timeout if remote server is down
curl_setopt($request, CURLOPT_CONNECTTIMEOUT, 30);
// set remote target url
curl_setopt($request, CURLOPT_URL, ""); //for testing post on current page
//Enable the post response.
//curl_setopt($request, CURLOPT_POST, true);
curl_setopt($request, CURLOPT_CUSTOMREQUEST, "POST");
$headers = ['Content-Type: multipart/form-data'];
curl_setopt($request, CURLOPT_HTTPHEADER, $headers);
//The data to transfer with the response.
curl_setopt($request, CURLOPT_POSTFIELDS, $postData);
//return the transfer as a string
curl_setopt($request, CURLOPT_RETURNTRANSFER, true);
// disable verification
curl_setopt($request, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($request, CURLOPT_SSL_VERIFYHOST, false);
Actually i don't have added file support.
My Problem
In Browser dev tools i cannot see any POST only GET responses.
I need a real POST with data in it not a urled GET one...
Hopefully someone can give help.
okay, misunderstood of server side and client side. Thought a response back to my location should result in a post response within dev tools of browser, this is not correct.
POST works.
So I am trying to retrieve only headers using cURL with the following:
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, true); // we want headers
curl_setopt ($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_TIMEOUT,10);
$output = curl_exec($ch);
The problem is that while trying to get headers of large file the script uses all the memory. I would like to avoid getting also the body and I have tried to use:
curl_setopt($ch, CURLOPT_NOBODY, true);
The problem is that this issues a HEAD request instead of GET. And some website retrun an error when you request with HEAD.
Is there any way with curl to retrieve only header without doing HEAD request?
First, don't use CURLOPT_RETURNTRANSFER as that's the option that makes it keep the entire response in memory.
Then, two options:
A) use a write callback and make that abort the transfer as soon as the first byte of the body is returned. There's a write callback example in the PHP.net docs.
B) use CURLOPT_RANGE and ask for only the first byte to be retrieved, 0-0. This avoids the write callback but has the downside that not all HTTP servers and URLs will acknowledge it.
If you dont have to use cURL, you could use get_headers(). By default get_headers uses a GET request to fetch the headers. And you could also modify that request by using stream_context_set_default()
$headers = get_headers('http://example.com');

I want to add the HTTP headers for authenticating Udemy API access.Can someone tell me as to how to add the headers.I already have the client id and secret key.I want to access the API from a PHP page.
https://developers.udemy.com/
Here is the code i tried using:
$ch = curl_init($request);
curl_setopt($ch, CURLOPT_URL, $request);
curl_setopt($ch,CURLOPT_HTTPHEADER,array('X-Udemy-Client-Id:MY_ID','X-Udemy-Client-Secret:Secret'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$results= curl_exec($ch);
echo $results;
Output:
Blank Page
Can someone point out what the problem might be?
As #drmarvelous wrote, you perform two requests (1st - by CURL, and 2nd - by file_get_contents) which does the same. Wherein the result of CURL request is not actually used in your script. It use the result of file_get_contents request which is performed without authentication parameters. Because of this you getting Unauthorized error.
So you have to use the result of CURL request:
...
$json = json_decode($results, true);
print_r($json);
Update:
You have to ensure you use valid URL for API request, i.e. value of $request in your code should be valid URL. Also, ensure you pass valid authentication parameters (Client-Id and Client-Secret) by HTTP headers.
Furthermore, since API is secured, you have to disable SSL peer verification by setting CURLOPT_SSL_VERIFYPEER option to false.
So the code should look like this:
$ch = curl_init($request);
curl_setopt($ch, CURLOPT_URL, $request);
curl_setopt($ch,CURLOPT_HTTPHEADER,array('X-Udemy-Client-Id: {YourID}','X-Udemy-Client-Secret: {YourSecret}'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$results= curl_exec($ch);
echo $results;
I'm trying to communicate with a web service who's waiting first a token in each request.
There is my problem, the web service is waiting the token throught file_get_contenst(php://input).
I didn't find a way to send cURL request trought this method (sending raw data/put data instead of Post).
Could some one guides me ?
I tried something like :
$fp = fopen('php://temp/maxmemory:256000', 'w');
fwrite($fp, TOKEN);
fseek($fp, 0);
curl_setopt($ch, CURLOPT_INFILE, $fp); // file pointer
curl_setopt($ch, CURLOPT_INFILESIZE, strlen($json));
curl_setopt($ch, CURLOPT_PUT, true);
For more info you can refer: How to start a GET/POST/PUT/DELETE request and judge request type in PHP?
HTTP PUT method is generally used to update resource.
First need to bring (GET) resource information.
and then update resource information according your parameters.
Finally, make PUT request to server.
In php, curl is used for making rest calls. HTTP GET and POST are directly supported in curl. But for PUT and DELETE you have to set options accordingly in curl_setopt()
$curl = curl_init($url);
**curl_setopt($curl,CURLOPT_CUSTOMREQUEST,"PUT")**;
curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);
curl_setopt($curl, CURLOPT_HTTPHEADER,$headers);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl,CURLOPT_POSTFIELDS,$update_para);
$curl_response = curl_exec($curl);
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.
