The api required to use post request with some fields, but i don't know where are the fields will be added!! ( in GET request i add the fields in the url like any request )
the api code
`
$apiKey = "8z8a7tupn5hubhjxqh8ubuz7";
$sharedSecret = "jsSJq2msbU";
$signature = hash("sha256", $apiKey.$sharedSecret.time());
$endpoint = "https://api.test.hotelbeds.com/activity-api/3.0/activities";
$request = new \http\Client\Request("POST",
$endpoint,
[ "Api-Key" => $apiKey,

It contains an array of filter with the following structure:

The Object “searchFilterItems” contains the following attributes: type > and value.
The following examples illustrate the different types and values for > each filter:

{"type": "country", "value": "PT"}

Answer 1

I had the same issue, took me a little while to figure it out. Turns out you need to use the Body class to represent the post data.
$msg = new http\Message\Body();
$msg->addForm([
'field1' => 'value',
'field2' => 'value2'
]);
$headers = null;
$request = new http\Client\Request('POST', 'https://example.com', $headers, $msg);
$client = new http\Client();
$client->enqueue($request);
$client->send();
$response = $client->getResponse();
There are some more methods available in the Message and Body class for including files, etc.

Try this way
$request = new http\Client\Request;
$body = new http\Message\Body;
$body->append('{Your JSON}');
$request->setRequestUrl('https://api.hotelbeds.com/hotel-api/1.0 hotels');
$request->setRequestMethod('POST');
$request->setBody($body);
$request->setHeaders(array(
'Accept' => 'application/json',
'Content-Type' => 'application/json',
'Api-Key' => $owapiKey,
'X-Signature' => $signature,
//'Accept-Encoding' => 'Gzip', //Deflate
'cache-control' => 'no-cache'
));
try {
$client = new http\Client;
$client->enqueue($request)->send();
$response = $client->getResponse();
if ($response->getResponseCode() != 200) {
echo("HTTP CONNECT FAILURE: -> ".
$response->getTransferInfo("effective_url").
$response->getInfo().$response->getResponseCode() );
} else {
$res=$response->getBody()->toString();
}
} catch (Exception $ex) { echo("Error while sending request, reason: %s\n".$ex->getMessage()); }
