I have been reading documentation and queries for several hours and I think I have a correct POST made with cURL.
It communicates correctly, because I receive the auth key and OK is validated, but then it doesn't receive any parameters from the post. I think some parameter must be missing, but I don't see anything in the documentation.
My code:
$data = "email=name#xxxx.com&template=3";
$url = "https://xxxx.net/xxx/aaa/bbb";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"keyname: keyvalue"
));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
Does anyone know if I should stick some more configuration??
I have a curl set up like this:
function file_get_contents_curl($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 400);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch,CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$data = curl_exec($ch);
return $data;
}
When I call it with the following:
$html = file_get_contents_curl("https://training.sap.com/service-id/module.php/core/as_login.php?AuthId=sf-sp&ReturnTo=%2Fsuccessfactors-community%2Fpermission-check");
You can see that link has an authentication, and I do not want to spend time on it. I just want that curl session to die after maybe 3 seconds or x seconds, or determine before hand if it is going to be a never ending loop on the curl for one reason such a SSL or password requirement etc.
I have the following PHP code:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://10.0.0.99/api/login");
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "somethingsomething");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: text/plain',
'Content-Length: 18')
);
$cookie = curl_exec($ch);
curl_setopt($ch, CURLOPT_URL, "https://10.0.0.99/api/getcmds");
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_COOKIE, "cookie=".$cookie);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: text/plain',
'Content-Length: 0')
);
$response = curl_exec($ch);
$json = json_decode($response, true);
curl_setopt($ch, CURLOPT_URL, "https://10.0.0.99/api/cmd/" . $json["value"]);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_COOKIE, "cookie=".$cookie);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "on");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: text/plain',
'Content-Length: 2')
);
curl_exec($ch);
curl_close($ch);
The first call to curl_exec posts the string as expected and returns the response. Second call also works as expected.
The third call however doesn't post the string "on" to the server. It correctly gets the returned data (which, without the "on" is an error), but the server never receives the posted data.
The code itself is running on PHP 5.5.30 in the command line using the -f flag. Curl Verbose mode is showing that the Content-Length is beeing set correctly, however it doesn't show anything about posted data. The rest of the post seems to be correct, it's just that no data arrives.
(PS: This is not supposed to be production code, just something I'm playing around with, so please no comments about code quality/security.)
You can try closing the connection and then starting again for a new call/request. I personally do this thing.
From php.net docs on cURL: PHP: curl_setop
As for CURL_POSTFIELDS:
This parameter can either be passed as a urlencoded string like 'para1=val1¶2=val2&...' or as an array with the field name as key and field data as value.
In your case, you set an empty variable $_POST['on']. If you want it to have some particular value:
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "on=value");
I have a Utility class that has to invoke a remote cPanel URL to create an email forwarding address, via cURL. This works perfectly well if I use regular curl_exec but fails if I try to make it non-blocking via curl_multi_exec - All I need to do is send a request and move on, I dont need to know the result - so it is a truly non-blocking requirement
Here is the code that works
$url = "https://mycpanel.com:2083/execute/Email/add_forwarder?domain=mydomain.com&email=email_fwd_146&fwdopt=pipe&pipefwd=php/piper.php&";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Basic " . base64_encode("user:pwd")));
$response = curl_exec($ch);
CakeLog::write('error', print_r($response, true));
curl_close($ch);
The response I get for above code is below (even though I really dont care about the response)
{
"messages":null,
"errors":null,
"status":1,
"metadata":{
"transformed":1
},
"data":[
{
"email":"email_fwd_146#mydomain.com",
"domain":"mydomain.com",
"forward":"|/home/myconsole/php/piper.php"
}]
}
Here is the code that does not work
$url = "https://mycpanel.com:2083/execute/Email/add_forwarder?domain=mydomain.com&email=email_fwd_146&fwdopt=pipe&pipefwd=php/piper.php&";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Basic " . base64_encode("user:pwd")));
$mh = curl_multi_init();
curl_multi_add_handle($mh,$ch);
curl_multi_exec($mh, $active);
This call never seems to reach the server or even execute. Any insight will be appreciated.
This is because curl_multi_exec() needs to be called over and over again until the transfers are complete.
I have the following php code
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_USERAGENT, $this->_agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->_headers);
curl_setopt($ch, CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_VERBOSE, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_COOKIEJAR, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
curl_setopt($ch, CURLOPT_POST, 1);
But I don't understand why is not working . The API that I'm posting the JSON to says that the parameters were not received . Is there anything wrong in my code ? I think the whole trick is on the JSON parameters... I'm not sure how to send them as I couldn't see any "nave->value" pair with the http analyzer as it usually appears in simple forms ... just that JSON code without any "name".
You can try as follows.
Basically if we have a array of data then it should be json encoded using php json_encode. And you should also add content-type in header which can be defined in curl as curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$data = array("country"=>"US","states"=>array("MHASASAS"=>"MH","XYZABABA"=>"XYZ"));
$postdata = json_encode($data);
$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);
you can use this and replace with
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
use this
$Parameters = array(
'MerchantCode' => $MerchantCode,
'PriceValue' => $amount,
'ReturnUrl' => $callback,
'InvoiceNumber' => $resnum,
);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($Parameters));
If:you use post method,you should know that:
CURLOPT_POST TRUE to do a regular HTTP POST. This POST is the normal application/x-www-form-urlencoded kind, most commonly used by HTML forms.
#see http://php.net/manual/en/function.curl-setopt.php
So:you can do like this:
$ar_form = array('name'=>'PHPJungle','age'=>66,'gender'=>'male');
$poststr = http_build_query($ar_form ); # important
$options[CURLOPT_HTTPGET] = false;
$options[CURLOPT_POST] = true;
$options[CURLOPT_POSTFIELDS] = $poststr ; //default type:application/x-www-from-urlencoded
curl_setopt_array ( $ch, $options );
# #todo your other codes
This is my class I have used for a long time.The class is based on PHP cURL.
It supports GET/POST，HTTP/HTTPS.
#see https://github.com/phpjungle/iHttp/
You can post a json data with curl like so:
Using Command Prompt:
curl -X POST -H "Content-Type: application/json" -d '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}' $url
Using PHP:
$data = array("folderId"=>"1","parameters"=>array("amount"=>3,"ascending"=>false,"offset"=>0,"sort"=>"date"));
$postdata = json_encode($data);
OR
$postdata = '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
You haven't set the content type, so the post data is being sent as form data. Try setting the content type to application/json.
If that doesn't work, try wrapping the json string with an array.
$link = "http://test.domain/myquery";
$json = '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}';
$postdata = json_decode($json);
echo openurl($link, $postdata);
This works as json decode converts a json string into array.
function openurl($url, $postvars = "") {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, '3');
$content = trim(curl_exec($ch));
curl_close($ch);
return $content;
}
if your API endpoint using body for send request using json data may be you can use Guzzle the doc is here doc.
use GuzzleHttp\Client;
$client = new Client();
$request = $this->client->post($url,array(
'content-type' => 'application/json'
),array());
$request->setBody($json_data);
$response = $request->send();
return $response;
hope this work.
You can do it make by steps:
$data = array(
'folderId'=>"1","parameters"=>array(
"amount"=>"3","ascending"=>false,"offset"=>0,"sort"=>"date"
)
);
$data_string = http_build_query($data);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($data));
curl_setopt($ch,CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result,true);
I don't know if you need the header. I think that by default it is already application/x-www-form-urlencode
If it doesn't work, try changing the $data values in array. Think it helps. :)
I'm not sure, that this is the solution but this works for me when posting json, change the json from
'{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}'
to
"{'folderId':'1','parameters':{'amount':3,'ascending':false,'offset':0,'sort':'date'}}"
The only change i made was the double quotes are now on the outside, that works for me but I'm obviously posting to a different server
Only other help I could offer is to download a network debugging tool such as Fiddler or Charles proxy and monitor the requests sent/received, it could be a case that something else is wrong in your code.
Hope i helped :)
first of all
please check the curl http status code
$http_code= curl_get_info($exec_res,CURL_HTTP_CODE);
then modify this request header set with post header API server add a recorder to log those request info.
