GET方法的PHP cURL函数

Question

I am trying to write a cURL function for GET method. Following is the code:

    $ch = curl_init();
    $token="43e6c623dda8f35dXXXXec57d58e91154a";
    $code="13200XX";
    $url="https://test.delhivery.com/c/api/pin-codes/json/?token=".$token."&filter_codes=".$code;
    echo $url;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPGET, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $return = curl_exec ($ch);
    curl_close ($ch);
    echo $return;

When I echo the above $url , I am getting the desired output but where I am wrong to write a cURL function, because when I am placing the same URL token in the cURL function I am getting blank page.

Please help me.

There may be plenty of reasons why it is not working.

Before doing all these steps below check if url in browser or postman or any other client returns correct response and also set error_reporting(E_ALL) and ini_set('display_errors', 1)

1. Check what's the output of echo curl_error($ch); if it's empty then go to next steps
2. Add browser header with curl_setopt() CURLOPT_USERAGENT some servers maybe set to deny connection if there is no browser header
3. Accept cookies in curl with curl_setop( ) CURLOPT_COOKIEFILE
4. This url is secure that is why you need either to add certifcate or set CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST options to 0
