JSESSIONID PHP Curl Request

I am trying to send a multi curl request to an api in order to retrieve data. This specific api requires a proper JSESSIONID cookie to be passed into the headers for it to work correctly.

The function I am using to send the request is:

function sendMultiRequest($data) {

    // initialize array of curl handles
    $curl_handles = array();
    // returned data
    $result = array();

    // initialize multi handle
    $multi_handle = curl_multi_init();

    //$cookie = generateCookie();

    $headers = array(
        'Content-type: application/json',
        'Cookie: JSESSIONID=39DDF47143F20CA952555027CD5F5EA2'
    );

    // loop through $data and create curl handles
    // then add them to the multi-handle
    foreach ($data as $key => $val) {

        $curl_handles[$key] = curl_init();

        curl_setopt($curl_handles[$key], CURLOPT_URL, $val);
        curl_setopt($curl_handles[$key], CURLOPT_HTTPHEADER, $headers);
        curl_setopt($curl_handles[$key], CURLOPT_RETURNTRANSFER, TRUE);
        curl_setopt($curl_handles[$key], CURLOPT_COOKIESESSION, TRUE);


        curl_multi_add_handle($multi_handle, $curl_handles[$key]);

    }

    // execute the handles
    $running = null;
    do {
        curl_multi_exec($multi_handle, $running);
    } while($running > 0);


    // get content and remove handles
    foreach($curl_handles as $key => $val) {
        $result[$key] = json_decode(curl_multi_getcontent($val), TRUE);
        curl_multi_remove_handle($multi_handle, $val);

    }

    // close curl_multi
    curl_multi_close($multi_handle);

    return $result;
}

I dont think it is the functions problem because my other multi requests work. But when I try to access the api, I don;t get data unless I pass in a correct JSESSIONID.

I know this because I am currently using the Advanced REST Client Google Chrome Extension and when I use the Cookie Request Header that the extension passes, the function works. However, the api credentials expire and so I need to programattically create and use a JSESSIONID.

I understand that I must use the curl opt COOKIEJAR and COOKIE somehow, but I am not too sure as I am new to this.

You only use CURLOPT_COOKIESESSION when you are trying to simulate the start of a new session. By doing this cURL will not load any session cookies from the cookie jar/file.

You also need to specify the cookie jar file to be used via CURLOPT_COOKIEJAR

So building on your example:

// then add them to the multi-handle
foreach ($data as $key => $val) {

    $curl_handles[$key] = curl_init();

    curl_setopt($curl_handles[$key], CURLOPT_URL, $val);
    curl_setopt($curl_handles[$key], CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl_handles[$key], CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl_handles[$key], CURLOPT_COOKIEJAR, '/path/to/cookie/file');
    // do this only if you need to force a new session and not load session cookie from cookie jar
    curl_setopt($curl_handles[$key], CURLOPT_COOKIESESSION, TRUE);


    curl_multi_add_handle($multi_handle, $curl_handles[$key]);

}

You should NEVER have to manually set your session id cookie value.
