I use cURL to send requests to REST API and I would like to add a string to created url befeore execute it. This string is not a parameter.
Do you know how can I do that?
It's called string concatenation. In php it can be done: $str = $string1.$string2;
p.s. Always read documentation before asking something. There you can find answers on most of your questions.
It depends on really what you want to do. If you want to call an URL by appending GET query parameters, you can use string concatenation.
<?php
function get_data($url, $add) {
$url = $url.$add;
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
echo get_data('http://example.com', '?page=mine');
?>
However, if you want to retrieve a specific URL by sending POST query parameters (e.g. to simulate a form being submitted), you need to implement something like this instead.

Im a newbie im trying to get a script to trigger another script with Curl in PHP but it dosent seem to be sending the paramaters.
Is there a seperate function to append parameters?
<?php
$time = time();
$message = "hello world";
$urlmessage = urlencode( $message );
$ch = curl_init("http://mysite.php?message=$urlmessage&time=$time");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
?>
Could anyone point me in the right direction??
The accepted answer is good for POST, but what if OP wanted specifically to GET? Some REST APIs specify the http method and often it's no good POSTing when you should be GETting.
Here is a fragment of code that does GET with some params:
$endpoint = 'http://example.com/endpoint';
$params = array('foo' => 'bar');
$url = $endpoint . '?' . http_build_query($params);
curl_setopt($ch, CURLOPT_URL, $url);
This will cause your request to be made with GET to http://example.com/endpoint?foo=bar. This is the default http method, unless you set it to something else like POST with curl_setopt($ch, CURLOPT_POST, true) - so don't do that if you specifically need to GET.
If you need to use one of the other http methods (DELETE or PUT for example) then use curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method). This also works for GET and POST.
You need curl_setopt() along with the CURLOPT_POSTFIELDS param.
That'll POST the given params to the target page.
curl_setopt($ch, CURLOPT_POSTFIELDS, 'foo=1&bar=2&baz=3');
PS: also check http_build_query() which is handy when sending many variables.
you need set CURLOPT_POST as true and CURLOPT_POSTFIELDS => parameters
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters);
a suggestion,set 'CURLOPT_RETURNTRANSFER', as true to return the transfer as a string of the return value of curl_exec($ch) instead of outputting it out directly

$mobile_number = $_POST['mobile_number'];
$sessionid = $_POST['session_id'];
CURLOPT_URL => 'https://xxyz.jkl.com/v2.0/search?varible_that_you_want_to_pass='.$mobile_number.'&requestId=1616581154955&locale=en-US&sessionId='.$sessionid,
Hi i need to send sms by using php. I am using curl method to post variables in url but i cant get sms. I can get result by using get method, is there any problem in my code?
$url = 'http://online.chennaisms.com/api/mt/SendSMS?';
$postData = array();
$postData['user'] = 'abc';
$postData['password'] = 'qwftgry ';
$postData['senderid'] ='reyty';
$postData['channel'] ='Trans';
$postData['DCS'] =0;
$postData['flashsms'] =0;
$postData['number'] = 91XXXXXXXXXX;
$postData['text'] ='hai ';
$postData['route'] =28;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
$result = curl_exec($ch);
curl_close($ch);
Try to delete ? character at the end of url
I don't see any problem in your code, apart from the lack of any error-checking on the cURL transaction (by means of curl_error() etc), so you should probably look elsewhere - was an error message returned by the SMS provider, for example?
I am trying to send OData parameters in a GET request to a RESTful API using PHP. A properly formatted OData request to this service looks like so:
https://myapi.org/endpoint?filter=family_name eq 'Doe'
It seems like I should just append these variables to the end of my CURLOPT_URL before sending the request, but the API service doesn't seem to receive the OData.
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('OSDI-API-Token:xxxxxxxxxxxx'));
curl_setopt($ch, CURLOPT_URL, "https://myapi.org/endpoint?filter=family_name eq 'Doe'");
$response = curl_exec($ch);
curl_close($ch);
echo "<pre>";
print_r($response);
echo "</pre>";
Output is NULL. This seems like a strange response considering that this same request with identical headers and the same Odata URL searches and finds the correct data in the API's browser.
Can anybody confirm whether or not this is the correct way to send OData parameters through a cURL request?
Appending the OData parameters directly to the CURLOPT_URL doesn't work, because it doesn't form a valid URL. The spaces and quotes need to be escaped as family_name%20eq%20%27Doe%27 or family_name+eq+%27Doe%27.
A simpler way would be to use http_build_query() to attach the parameters to the URL prior to setting CURLOPT_URL:
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('OSDI-API-Token: xxxxxxxxxx'));
$api_request_parameters = array('filter'=>"family_name eq 'Doe'");
$api_request_url = "https://myapi.org/endpoint";
$api_request_url .= "?".http_build_query($api_request_parameters);
$curl_setopt($ch, CURLOPT_URL, $api_request_url);
$response = curl_exec($ch);
curl_close($ch);
I know that this question has been closed for a while but just to complement the answer with more points above, you need to declare '$' in the filter key if you are going to use http_build_query (), for example:
$api_request_parameters = array ('$filter' => "family_name eq 'Doe'");
$api_request_url. = "?". http_build_query ($api_request_parameters);
If you declare without '$' in filter, the filter will not work correctly and the return of this will be all records and in some cases it may return an error.
If you choose not to use http_build_query () you need to escape all spaces, for example, let's say the request is this:
https://myapi.org/endpoint?filter=family_name eq 'Doe test 1234'
The parameters would look like this:
https://myapi.org/endpoint?filter=family_name+eq+%27Doe%20test%201234%27
I am trying to take a list of URL's from a textbox, it has 1 URL per line and each URL does a redirect, I am trying to get the URL that it redirects to.
When I run this code below on a single URL, it returns the redirected URL which is what I want...
function getRedirect($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = curl_exec($ch);
$info = curl_getinfo($ch); //Some information on the fetch
curl_close($ch);
echo '<pre>';
print_r($info);
echo '</pre>';
}
$url = 'http://www.domain.com/go?a:aHR0cDovL2xldGl0Yml0Lm5ldC9kb3d';
getRedirect($url);
Now my problem is when I try to run it on multiple URL's with this code...
if(isset($_POST['urls'])){
$rawUrls = explode("\n", $_POST['urls']);
foreach ($rawUrls as $url) {
getRedirect($url);
}
}
When I run it on my list of URL's instead of giving me the redirected URL like my first example does correctly, it instead gives me the URL that I passed into cURL.
Can someone help me figure out why or how to fix this please?
It's already covered in the question comments but it seems the problem would be extra spacing at the end of the url.
Calling getRedirect(trim($url)) would fix it.
The space at the end is most likely turned into a querystring space (aka %20) and changes the value of query string parameters
