I try to send a post request to another php page with the following code:
$vars = ['val1' => 'myval'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_MAXREDIRS, 4);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_USERPWD, "username:password");
$data = curl_exec($ch);
curl_close($ch);
But on the target page, var_dump($_POST); will output only "1". I had expected something like:
array(val1 = myval) or something similar. So that i can check with isset($_POST["val1"]) if this exists and contains "myval".
Any ideas whats wrong with the request?
Edit:
I have now changed my code to the following:
<?php
$data = array(
'foo'=>'bar',
'baz'=>'boom',
'cow'=>'milk',
'php'=>'hypertext processor');
$ch=curl_init();
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_URL, "target.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
echo $response;
?>
And in target.php:
<?php
echo print_r($_POST, true));
?>
But there is no response. Both files are in the same dir at the server.
That's because curl_setopt() doesn't accept such complext types as array ;) You need to present your data in form of a query string: "postvar1=value1&postvar2=value2&postvar3=value3".
$format = http_build_query($vars);
curl_setopt($ch, CURLOPT_POSTFIELDS, $format);
or
$format = "val1=my-value"; // be careful to create proper encoding
curl_setopt($ch, CURLOPT_POSTFIELDS, $format);
If you're using CURLOPT_POSTFIELDS, you don't need to set CURLOPT_POST as well. In fact, setting it after will result in a potentially incorrect header being sent.
CURLOPT_POSTFIELDS accepts an array, and will set the Content-Type header to multipart/form-data if one is provided. Later, setting CURLOPT_POST will overwrite this to application/x-www-form-urlencoded, and means that the PHP script at the other end will expect data encoded as an HTTP query-string. This is why you're having problems.
You can fix this either by encoding $vars correctly before sending (using http_build_query, as in the other answer), or just remove the call to set CURLOPT_POST. I'd recommend the latter.
I think, i got it. When i set as target something like "target.php", data was not send. But when i use a complete URL, like https://myserver.com/target.php, this will work as expected. Sometimes, its to easy... sorry for stealing your time.
I'm sending few parameters, via post to an url using CURL, the url is supposed to return the results in a XML, but instead it returns a string with the result.
If I copy the url and my variables and paste it in the browser, it returns the desired XML.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $variables);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
$result = curl_exec($ch);
$error = curl_error($ch);
curl_close($ch);
print_r($result);
That's the piece of code that I'm using. Am I missing something?
Thanks in advance.
Take the string that cURL returns and turn it into an XML object
$xml = simplexml_load_string($result);
SimpleXML documentation HERE
Try to add http headers:
curl_setopt($ch, CURLOPT_HTTPHEADER, [
"Content-type: text/xml;charset=\"utf-8\"",
"Accept: text/xml",
]);
Im generating a POST request:
$data['v'] = '2';
$data['file'] = gz compressed data
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$content = curl_exec($ch);
After this, the "file" field gets lost - it wont arrive to the server, all others do. What can I do?
When uploading files, curl is expecting the full path to your file (don't forget to prepend the '#' symbol), and not the binary data:
$data = array(
'file' => "#/path/to_your_file_not_binary_data",
'v' => '2'
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
see here: http://www.php.net/manual/en/function.curl-setopt.php
Also, if you need to specify the Content-Type header:
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));
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.
I am attempting to make an xml post request which expects a response using curl to build the headers and content. Here is my code:
<?php
function post_xml($url, $xml) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: application/xml; charset=utf-8"));
curl_setopt($ch, CURLOPT_USERPWD, 'myusername:mypassword');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$result = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
return $result;
}
$xml = '<?xml version="1.0" encoding="UTF-8"?><testing><test type="integer">1</test></testing>';
$url = "http://example.com/api/test.php";
$result = post_xml($url, $xml);
echo "<pre>"; print_r($result); echo "</pre>";
?>
To view my outgoing request I use:
$info = curl_getinfo($ch);
echo($info['request_header']);
The resulting HTTP request that is sent is:
POST /api/test.php HTTP/1.1
Authorization: Basic pwmtJdCVwNEawdaODH
Host: example.com
Accept: */*
Content-Type: application/xml; charset=utf-8
Content-Length: 95
The content-length is 95, but then it shows none of the xml content below. This results in a 422 Unprocessable Entity error. Am I completely missing something? I expected to be able to see the XML in the request sent.
You haven't specified a fieldname for your XML content, so PHP has nowhere to assign it in the POST request. As the manual states:
This parameter can either be passed as a urlencoded string like 'para1=val1¶2=val2&...' or as an array with the field name as key and field data as value.
So try:
curl_setopt($ch, CURLOPT_POSTFIELDS, array('xml' => $xml));
Don't know if this is what your API is expecting, but it's one thing to look into.
As for displaying the XML, remember that browsers can/will interpret it as HTML, and any unknown tags will simply not be displayed. Try doing your output as:
echo "<pre>";
echo htmlspecialchars($result);
echo "</pre>";
and/or outputting header('Content-type: text/plain') so that the XML tags will be displayed as-is and not be interpreted as unknown html tags.
echo($info['request_header']);
will only show the header that was sent. It will not show the post data, so you should not see the XML string.
It works when I removed the header line:
//curl_setopt($ch, CURLOPT_HTTPHEADER, ...
Final code:
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('data' => $xml));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1);
