i am beginner to graph api/php . i want to get events data against page_id etc.when i paste url into browser it returns json data but when i use curl or file_get_contents(); method it returns "Null". What is the proper way to sending request and getting response. this is my basic code and other than this i am NOT using any kind of include files etc.
$json_link = "https://graph.facebook.com/getwellgabby/events/attending/?fields=id,name,description,timezone,start_time,cover&access_token=206516302813755|lRnrKAiu3Z......&since=1356998400&until=1483228800";
file_get_contents($json_link);
$obj = json_decode($json, true, 512, JSON_BIGINT_AS_STRING);
var_dump($json);
RESULT: boolean (false)
https://developers.facebook.com/docs/graph-api/reference/v2.3/event/attending
As you can see in the docs, the correct way to get attendees for an event is to use the Event ID:
https://graph.facebook.com/{event-id}/attending?access_token=xxx
You can´t get all attendees for all events in one API call, you have to do this event by event. Test it in the API explorer before using any PHP code.
Btw, you should use CURL instead of file_get_contents. The PHP SDK uses CURL too.

I develop at php Laravel.
I receiving GuzzleHttp response from Mailgun as Object and can't to get from it the status.
the Object is:
O:8:"stdClass":2:{s:18:"http_response_body";O:8:"stdClass":2:{s:6:"member";O:8:"stdClass":4:{s:7:"address";s:24:"test_of_json-4#zapara.fr";s:4:"name";s:10:"not filled";s:10:"subscribed";b:1;s:4:"vars";O:8:"stdClass":0:{}}s:7:"message";s:36:"Mailing list member has been created";}s:18:"http_response_code";i:200;}
I need just last data pair:
"http_response_code";i:200;
to get it into variable, like:
$http_response_code = 200;
or even just its value.
To get string as I cited above I use
$result_ser = serialize($result);
but yet can't to extract value of variable.
Also I tried this:
$this->resultString .= \GuzzleHttp\json_decode($result_ser, true);
and get error.
Please, explain me , How to get/extract value I needed?
To take the response status code you can use the function getStatusCode :
$response = $client->request();
$statusCode = $response->getStatusCode();
while to take the body of response you can use :
$contents = $response->getBody()->getContents();
let's consider your request is something like
$response = $client->get("https://example.com");
if ( $object_res->getStatusCode() == 200 ) { // here you are checking your http status code
}
$object_res->getStatusCode() is the method to get http status code.
refer docs, there is simple example in this page.
I found that 'mailgun/mailgun' package uses its own HTTP client which also uses 'RestClient' and these classes are return stdObject.
In that Object there is property 'http_response_code' containing HTTP response code like 200, 400, 401 etc.
This property accessible by standard way $object->property and it's a solution of my query in this case.
For anybody who will read this question and answers I should to explain one thing that I not cleared in question.
I made request to the Mailgun API for subscribing member to mailing list. The API returns stdObject, not JSON or XML data.
But also there is one more strange thing - stdObject returned when request is successful only. If request fails you'll get just Exception thrown with message and without code. This forced me, if fail, to parse message body instead of get and resolve error code.
$responseObj->getStatusCode();
I am working with a Webhook based of of SendGrid's API v3. The Webhook is completely set up with an endpoint that SendGrid posts to, but I need to be able to receive that parsed data and store it in a database using PHP, but do not know how to do that.
I have worked with APIs before where I initiate the retrieval or POST of data, but when the API server is the one POSTing, how do I catch the data being parsed through the Webhook endpoint? I have some simple thus far, but am really unclear of how to tackle this:
<?php
$json = file_get_contents('https://example.com/webhook.php');
$json_decoded = json_decode($json, true);
$var_dump(json_decoded);
?>
I have tried sending multiple emails to the host, but every time I make this call I return NULL.
Try using the code from this example. This will give you the raw HTTP request body bytes to decode.
<?php
$data = file_get_contents("php://input");
$events = json_decode($data, true);
foreach ($events as $event) {
// Here, you now have each event and can process them how you like
process_event($event);
}
?>

One of my partners has an API service which should send an HTTP POST request whenever a new file is published. This requires me to have an api file which will get the POST this way:
http://myip:port/api/ReciveFile
and requesting that the JSON format request should be:
{
"FILE ":"filename.zip",
"FILE_ID":"123",
"FILE_DESC":"PRUPOUS_FILE",
"EXTRAVAR":"",
"EXTRAVAR2":"",
"USERID":" xxxxxxxxxxxx",
"PASSWORD":"yyyyyyyyyyy"
}
Meanwhile it should issue a response, in JSON format if it got the file or not
{"RESULT_CODE":0,"RESULT_DESCR":""}
{"RESULT_CODE":1001,"RESULT_DESCR":"Bad request"}
And after, when I am finished elaborating the file, I should send back the modified file same way.
The question is, now basically from what I understand he will send me the variables witch I have to read, download the file, and send a response back.
I am not really sure how to do this any sample code would be welcomed!
I'm not sure exactly what the question is, but if you mean creating a success response in JSON for if an action occurred while adding data to it which is what can be understood from the question, just create an array with the values you wish to send back to the provider and do json_encode on the array which should create json and just print it back as a response.
About receiving the information; all you have to do is use the integrated curl functions or use a wrapper (Guzzle, etc) to output the raw JSON or json_decode data into a variable and do whatever you please with it.
From what I read in the question, you wish to modify the contents of it. This can be achieved by just decoding the json and changing the variables in the array, then printing the modified JSON back as a response.
Example (this uses GuzzleHTTP as an example):
$res = $client->request('GET', 'url');
$json = $res->getBody();
$array = json_decode($json, 1); // decode the json
// Start modifying the values or adding
$array['value_to_modify'] = $whatever;
$filename = $array['filename']; // get filename
// make a new request
$res = $client->request('GET', 'url/'.$filename);
// get the body of specified filename
$body = $res->getBody();
// Return the array.
echo json_encode($body);

So I made a simple HTTP request to Pinterest's API to get the count of a link:
$this->load->library('rest');
$this->rest->initialize(array('server' => 'http://api.pinterest.com/'));
$return_data = $this->rest->get('v1/urls/count.json?callback=&url=' . $link);
The response I get is:
receiveCount({"count": 5743, "url": "http://google.com"})
You can try this yourself here.
I don't want the callback and I tried setting callback= but the parenthesis are still present so I can't parse it via json_decode.
Is there a better way of getting a pure json response without having to string replace the parenthesis myself?
The Pintrest API is currently in development and is not ready for public use; they removed their own documentation a while ago. There is however a cache on Bolt for v2 of the API.
For now I would just do a regex on the response such as
$return_data = preg_replace('/^receiveCount\((.*)\)$/', "\\1", $return_data);
And then json_decode that.
i am kind of new to API thing, and i need help understanding on what exactly is happening with the below Code.
$address = 'Bhatkal, Karnataka, India';
$requestUrl = 'http://maps.google.com/maps/geo?output=xml&key=aabbcc&oe=utf-8&q='.urlencode($address);
$xml = simplexml_load_file($requestUrl);
i understand that HTTP is capable of sending Request and getting response in return isn't it? what i am unable to understand is the third and last function that is $xml = simplexml_load_file($requestUrl); when i do a print_r($xml) i get an object in return which prints all the object details i got back as response,
how does the function process the
URL?
does it use CURL (i have very less idea about what is CURL).
and where do i look up for Google Maps API URL?
That function does not process the request (nor the URL), only the response, Google processes the URL that, the function just "visit's" it. You can do as well: here. The XML file you see here is ending up in the variable $xml, parsed.
EDIT: the URL in this post is not working too well, because of the key parameter
simplexml_load_file internally uses the fopen wrapper and opens the remote xml that would be produced by the url and then converts into an array for php to easily use.
The response object will help you to extract the data from the response.
