Why does the site not provide the necessary cookies?

Question

PHP

I went into inspector mode, made copy as cURL through the site and generated a curl request.

curl_setopt($ch, CURLOPT_URL, 'myURL');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_ENCODING, 'gzip, deflate');
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);

I send all Headers. The site answers me with an answer 200, everything seems to be fine, but at the same time in the browser the answer is - Status Code: 304 Not Modified

And now about the problem:
I need to receive cookies from the site.

Here is a photo of what I see in the browser:


The site gives 2 cookies that I need: ak_bmscand akacd_activate_*****_com_phased_release

Now I make a cURL request and I get cookies:
akacd_activate_*****_com_phased_releaseand bm_szand _abck, i.e. the site does not give me cookies that we see in the browser, but gives some others.

Maybe you need to add some settings to cURL?

Answer 1

The "HTTP 304 Not Modified" client code indicates that it is not necessary to resubmit the requested resources. This is an implicit redirect to a cached resource.
clipping from MDN - 304 Not Modified

Perhaps your server reacts differently to requests from the user (User-Agent) and from a third-party server (Host)

The site gives 2 cookies that I need: ak_bmsc and akacd_activate_*****_com_phased_release
Now I make a cURL request and I get cookies:
akacd_activate_*****_com_phased_release and bm_sz and _abck, i.e. the site does not give me cookies that we see in the browser, but gives some others.

Try passing the User-Agent in the request in addition, like this:

curl_setopt_array($ch, [
    CURLOPT_URL, 'myURL',
    CURLOPT_RETURNTRANSFER, true,
    CURLOPT_FOLLOWLOCATION, true,
    CURLOPT_ENCODING, 'gzip, deflate',
    CURLOPT_COOKIEFILE, $cookiefile,
    CURLOPT_COOKIEJAR, $cookiefile,
    CURLOPT_USERAGENT, '' // Впишите сюда User-Agent из вашего браузера
    ]);

PS why is this ? By default and so GET. PPS Why do CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR have the same file? curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
