如何使用Kimono RESTful API更新参数?

Specifically I am looking to update the URLs that are to be scraped. Documentation can be found here: https://www.kimonolabs.com/apidocs#SetCrawlUrls

Unfortunately my knowledge about cURL and RESTful APIs is limited to say the least. My most recent failed attempt was:

$ch = curl_init("https://kimonolabs.com/kimonoapis/");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json', 'kimonoapis/$api_id/update'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $data)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

where $data is an array of:

array(2) {
  ["apikey"]=>
  string(32) "API_KEY"
  ["urls"]=>
  array(2) {
    [0]=>
    string(34) "URL 1"
    [1]=>
    string(34) "URL 2"
  }
}

I have also tried variations of json_encode, passing the parameters in the query string, and different variations of cURL but have not be successful thus far. How do you successfully take advantage of their RESTful API?

    $array = array('apikey' => 'API_KEY', 'urls' => array('URL_1', 'URL_2'));
    $postvars = http_build_query($array);
    $url = "https://kimonolabs.com/kimonoapis/{API_ID}/update";
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
    $result = curl_exec($ch);
    curl_close($ch);
    

    After a lot more trail, error, and Google this is what I finally got to work. Thanks for all the help @JohnSvensson

    The variable $api_id is not being interpreted because you are using single-quotes.

    Example:

    <?php
    
    $var = "api";
    
    var_dump(array('$api'));
    

    Outputs:

    array(1) { [0]=> string(4) "$api" }
    

    Related read: What is the difference between single-quoted and double-quoted strings in PHP?

    Try changing the line:

    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json', 'kimonoapis/$api_id/update'));
    

    To use double-quotes, or concatenate the $api_id variable 'kimonoapis/' . $api_id . '/update'

    Update:

    Since the API expects JSON, you should do this:

    $payload = json_encode( array('api_key' => 'key', 'urls' => array('url1', 'url2' ) );
    curl_setopt( $ch, CURLOPT_POSTFIELDS, $payload );
    

    When using an array as you do, according to the manual If value is an array, the Content-Type header will be set to multipart/form-data. Hence the 400 error.

    Update 2:

    $ch = curl_init("https://kimonolabs.com/kimonoapis/");
    $data = json_encode(array('apikey' => 'yourkey', 'urls' => array('url1', 'url2')));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json', 'kimonoapis/' . $api_id . '/update'));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data)
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($ch);
    $info = curl_getinfo($ch);
    curl_close($ch);
