I want to make a post to a server I have by using php.
I was thinking in curl but all examples I find, urlfy data and I have to send a json file but not in the url.
I already have the json in an array : 'key'=>'value'...
I have to add headers, I think I can with this:
curl_setopt($ch,CURLOPT_HTTPHEADER,array('HeaderName: HeaderValue','HeaderName2: HeaderValue2'));
but I don't knoe how to add my array and post it.
Any idea?
I need to add a json like this:
[{"a":"q",
"b":"w",
"c":[{
"e":"w",
"r":"t"
}]
}]
Here how you can post the data using CURL, and as you mentioned you already have a json you can do so as
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, 'your api end point');
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields); // $postfields is the json that you have
$request_headers = array();
$request_headers[] = 'HeaderName: HeaderValue','HeaderName2: HeaderValue2';
$request_headers[] = 'Content-Type: application/json','Content-Length: ' . strlen($postfields) ;
curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);
$response = curl_exec($ch);
curl_close ($ch);

Im trying to create a simple api that will post json to an endpoint using curl and php. its giving me an error whereby its saying unsupported media type and i need help seeing what it is i might be doing wrong, here is the code
<?php
$data = array("saleAmount"=>"2000","cashBack"=>"800","posUser"=>"John","tenderType"=>"SWIPE","currency"=>"RTGS","transactionId"=>'0001');
$payload = json_encode($data);
echo $payload;
// prepare curl
$ch = curl_init('http://localhost:9111/api/requests');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/jsonp',
'Content-Length: ' . strlen($payload))
);
// Submit the POST request
$result = curl_exec($ch);
echo json_encode($result);
// Close cURL session handle
curl_close($ch);
?>
The issue is that your API is expecting a different media type than the one you are providing in your quest.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/415
Make sure that your API supports the content-type application/json
$url="";//path of api
$ch=curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json')
);
$data = array("saleAmount"=>"2000","cashBack"=>"800","posUser"=>"John","tenderType"=>"SWIPE","currency"=>"RTGS","transactionId"=>'0001');
$data=json_encode($data);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
$response=curl_exec($ch);
print_r($response);die;
curl_close($ch);
Append your url in $url and check this once.
I have rest API of Nodejs Server, I'm trying to make a POST call to it using PHP.
My php code is:
function post_url($apiRoute,$data) {
$request_url = 'http://test-app.herokuapp.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url . $apiRoute);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
echo $data ;
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
I have tried calling this function with diff forms of data:
$g = array("_id" => "111");
$postapiresponse = post_url('/CCTRequest/get',json_encode($g));
OR
$postapiresponse = post_url('/CCTRequest/get',json_encode(array("_id" => "111"));
But on server side which Node.js, when I console log req.body I get data like this:
{ '{"_id":"111"}': '' }
How should I pass the data in PHP so I can get proper obj in node.js i.e:
{ '_id': '111' }
See the PHP document:
http://php.net/manual/en/function.curl-setopt.php
CURLOPT_POST:
TRUE to do a regular HTTP POST. This POST is the normal
application/x-www-form-urlencoded kind, most commonly used by HTML forms.
CURLOPT_POSTFIELDS:
If value is an array, the Content-Type header will be set to multipart/form-data.
So you can pass a query string returned by http_build_query() into CURLOPT_POSTFIELDS:
post_url('/CCTRequest/get', http_build_query($g, null, '&'));
and remove curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));. (In fact, the varieble should be $ch, but you typed $curl, so this line doesn't work.)
In the other way, you can replace curl_setopt($ch, CURLOPT_POST, 1); with
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');, it can prevent the data be encoded automaticlly. And then send json_encode() data.
I have solved by using http_build_query($g, null, '&') for making data.
$g = array("_id" => "111");
$g = http_build_query($g, null, '&');
$postapiresponse = post_url('/CCTRequest/get', $g);
You have a typo in the code, which will prevent it setting the header $curl should be $ch:
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
You also need CURLOPT_RETURNTRANSFER uncommented.
function post_url($apiRoute, $data) {
$request_url = 'www.example.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url . $apiRoute);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type:application/json']);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
I just got API access for one of the website on the internet, and as a new api developer i got into troubles understanding how should i start and with what, So hope you guys guide me . They don't have Documents or tutorials Yet.
If anyone can give me a small example on how to send Http post request that includes Header and body? As what they are mentioning in the API page:
All requests must include an Authorization header with siteid and
apikey (with a colon in between) and it must match with the siteid and
apikey in the request body
In the body the Parameter content type will be application/json. They have also provided a Base URL.
The response will be as application/json.
What should i do? is the request can be sent using AJAX? or there is PHP code for this? i have been reading a lot about this subject but none enter my head. Really hope you guys help me out .
Please let me know if you need more information so i can provide it to you.
EDIT : Problem solved and just posting the small editing that i did to the code that was provided in the correct answer that i marked .
Thanks to Mr. Anonymous for the big help that he gave me . His answer was so so close, all what i had to do is just edit his code a little bit and everything went good .
I will list the finial code down bellow in case any other developer had this issue or wanted to do an HTTP request .
First what i did is that i stored the data that i wanted to send over the HTTP in a file with a JSON type :
{
"criteria": {
"landmarkId": 181,
"checkInDate": "2018-02-25",
"checkOutDate": "2018-02-30"
}
}
Second thing as what guys can see what Mr. Anonymous posted .
<?php
header('Access-Control-Allow-Origin: *');
$SiteID= 'My Site Id';
$ApiId= 'My Api Id';
$url = 'Base URL';
// Here i will get the data that i created in Json data type
$data = file_get_contents("data.json");
// I guess this step in not required cause the data are already in JSON but i had to do it for myself
$arrayData = json_decode($data, true);
$ch = curl_init();
//curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$SiteID:$ApiID");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Connection: Keep-Alive',
'Authorization: $SiteID:$ApiId'
));
curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($arrayData));
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
?>
Try this
$site_id = 'your_site_id';
$api_key = 'your_api_key';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://api-connect-url');
curl_setopt($ch, CURLOPT_POST, 1);
############ Only one of the statement as per condition ###########
//if they have asked for post
curl_setopt($ch, CURLOPT_POSTFIELDS, "$site_id=$api_key" );
//or if they have asked for raw post
curl_setopt($ch, CURLOPT_POSTFIELDS, "$site_id:$api_key" );
####################################################################
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ["$site_id:$api_key"] );
$api_response = curl_exec ($ch);
curl_close ($ch);
As asker need to send JSON Payload to API
$site_id = 'your_site_id';
$api_key = 'your_api_key';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://api-connect-url');
curl_setopt($ch, CURLOPT_POST, 1);
//send json payload
curl_setopt($ch, CURLOPT_POSTFIELDS, "{
"criteria":{
"cityId":9395,
"area":{
"id":0,
"cityId":0
},
"landmarkId":0,
"checkInDate":"2017-09-02",

},
"occupancy":{

}
}
}"
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ["$site_id:$api_key", 'Content-Type:application/json'] );
$api_response = curl_exec ($ch);
curl_close ($ch);
This is my sample JSON Request
{
"Username":"admin",
"Password":"root123",
"PinCode” : "hello321"
}
And also I want to post a request token as well, the request token has to be posted as a Request Header.
When I successfully sent those data and valid token, I need to receive a jSON response as below,
{
"Title": "Mr.",
"Name": "Pushkov",
"Age": "18"
}
My Question is,
How can I POST my above mentioned JSON data and the token in PHP cURL and display an error if the details are wrong in code igniter?
This is what I have done so far..and its not giving me the exact output im looking for and I couldn't figure out a way to send my token as a header request...
public function send_veri(){
$url='http://helloworld21.azurewebsites.net/api/member/login';
$ch = curl_init('http://localhost/apphome');
$data = array("Username" =>$this->input->post('un'), "Password" =>$this->input->post('pw'), "PinCode" =>$this->input->post('VerificationCode'));
$data_string = json_encode($data);
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
//curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
}
once I run this, I could only get Username, Password and the PinCode only. I cannot post the request token in my header, in causing of that i cannot get the member detail response.
For Sending Data -
public function send_veri(){
$url='http://helloworld21.azurewebsites.net/api/member/login';
$ch = curl_init( $url );
$bodyData=json_encode(array()); // here you send body Data
$data = json_encode(array("Username" =>$this->input->post('un'), "Password" =>$this->input->post('pw'), "PinCode" =>$this->input->post('VerificationCode')));
curl_setopt( $ch, CURLOPT_POSTFIELDS, $bodyData );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array("headerdata: ".$data.",Content-Type:application/json"));
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
$result = curl_exec($ch);
curl_close($ch);
}
Get Header data on Apache Server Code -
$hEAdERS = apache_request_headers();
$data = json_decode($hEAdERS['headerdata'], true);
echo $contentType=$hEAdERS['Content-Type'];
echo $Username = #trim($data['Username']);
echo $Password = #trim($data['Password']);
echo $PinCode = #trim($data['PinCode']);
It works for me.
Hello I am passing an JSON array from one server say www.example1.com and I want to receive that data on another server say www.example2.com/test.php . I have tried this using cURL but I am not getting that data at the receiving. Following is my code
Code at Sender
$send_data = json_encode($myarray);
$request_url = 'www.example2.com/test.php';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $request_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, 'send_data='.$send_data);
$response = curl_exec($curl);
$curl_error = curl_error($curl);
curl_close($curl);
Code at Receiver
if(isset($_REQUEST['send_data'])){
$userinfo = json_decode($_REQUEST['send_data'],true);
print_r($userinfo);
}
How do I fetch the data at receiver's end.
Try this method.
FILE: example1.com/sender.php
$request_url = 'www.example2.com/test.php';
$curl = curl_init( $request_url );
# Setup request to send json via POST.
$send_data = json_encode($myarray);
curl_setopt( $curl, CURLOPT_POSTFIELDS, $send_data );
curl_setopt( $curl, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
# Return response instead of printing.
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
# Send request.
$result = curl_exec($curl);
curl_close($curl);
# Print response.
echo "<pre>$result</pre>";
on your second page, you can catch the incoming request using file_get_contents("example1.com/sender.php"), which will contain the POSTed json. To view the received data in a more readable format, try this:
echo '<pre>'.print_r(json_decode(file_get_contents("example1.com/sender.php")),1).'</pre>';
Use the following
FILE: example1.com/sender.php
<?php
header('Content-Type: application/json'); echo
json_encode(array('response1' => 'This is response1', 'response2' => 'This is response2', $_POST));
?>
FILE: example2.com/receiver.php
<?php
$request_url = 'http://www.example1.com/sender.php';
$sendData = array('postVar1' => 'postVar1');
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $request_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, 'sendData=' . http_build_query($sendData));
print_r($response = curl_exec($curl));
curl_close($curl);
?>
You will get a JSON object as a cURL response.
