passing json data as post - php

Question

i am new to api so i may be completely wrong.
i was going through some docuementaion in github but could not find some answers so i am here
i want to pass url of these functions to api.php
after validating these key and secret.when i echo these data i get key, secret and url but how to get these details in php as its not a post and i cant use _post function to manipulate data based on url submitted and give the result
public function __construct($key = '', $secret = '', $timeout = 30,
$proxyParams = array()) {
$this->auth = array(
"auth" => array(
"api_key" => $key,
"api_secret" => $secret
)
);
$this->timeout = $timeout;
$this->proxyParams = $proxyParams;
}
public function url($opts = array()) {
$data = json_encode(array_merge($this->auth, $opts));
// echo $data;
$response = self::request($data, 'http://somesite.com/a/api.php', 'url');
return $response;
}
here is request function
private function request($data, $url, $type) {
$curl = curl_init();
if ($type === 'url') {
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json'
));
}
curl_setopt($curl, CURLOPT_URL, $url);
// Force continue-100 from server
curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.85 Safari/537.36");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_FAILONERROR, 0);
curl_setopt($curl, CURLOPT_CAINFO, __DIR__ . "/cacert.pem");
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, $this->timeout);
if (isset($this->proxyParams['proxy'])) {
curl_setopt($curl, CURLOPT_PROXY, $this->proxyParams['proxy']);
}
$response = json_decode(curl_exec($curl), true);
if ($response === null) {
$response = array (
"success" => false,
"error" => 'cURL Error: ' . curl_error($curl)
);
}
curl_close($curl);
return $response;
}
}
output of echo data is sufficient but its not post and i tried json_decode but nothing is coming to api.php
here is output of echo
{"auth":{"api_key":"be8fgdffgrfffrffc4b3","api_secret":"1b59fsfvfrgfrfvfb29d6e555a1b"},"url":"https:\/\/i.ndtvimg.com\/i\/2017-06\/modi-at-kochi-metro-station_650x400_81497685848.jpg","wait":true}
i tried these in api.php to get the data but nothing is working
$gggss['url'] = json_decode($data, true); //this returns an array
or
$gggss=$_POST['data'];
any help will be great

I think you are trying get urlencoded data, while your JSON string located in body of request. Try use this instead:
$entityBody = file_get_contents('php://input');
