贝宝IPN侦听器—使用CURL发送响应

Question

I'm trying to setup my PayPal IPN Listener with CURL. I'm receiving the POST data from Paypal just fine, but I'm stuck when sending my response back.

This is a test I'm trying to send back to Paypal, looking for the expected "VERIFIED" or "INVALID" response.

    $string = 'cmd=_notify-validate&test_ipn=1&payment_type=instant&payment_date=13%3A49%3A46+Dec+01%2C+2010+PST&payment_status=Completed&address_status=confirmed&payer_status=verified&first_name=John&last_name=Smith&payer_email=buyer%40paypalsandbox.com&payer_id=TESTBUYERID01&address_name=John+Smith&address_country=United+States&address_country_code=US&address_zip=95131&address_state=CA&address_city=San+Jose&address_street=123%2C+any+street&business=seller%40paypalsandbox.com&receiver_email=seller%40paypalsandbox.com&receiver_id=TESTSELLERID1&residence_country=US&item_name=something&item_number=AK-1234&quantity=1&shipping=3.04&tax=2.02&mc_currency=USD&mc_fee=0.44&mc_gross=12.34&mc_gross_1=9.34&txn_type=web_accept&txn_id=461212149&notify_version=2.1&custom=xyz123&charset=windows-1252&verify_sign=AHaXyf3zaDTb0y4MveMg3L5zjpqNAElZcXU6rvpq5jsGR30FGG6OehkN';

    $endpoint = 'https://www.sandbox.paypal.com/';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $endpoint);
    curl_setopt($ch, CURLOPT_HEADER, TRUE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $string);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    $result = curl_exec($ch);
    curl_close($ch);

    echo $result;

I'm using the Sandbox IPN Testing Simulator to send IPN signals to my listener. I'm sending my responses to https://www.sandbox.paypal.com/ .

I get this response from Paypal no matter what data I send to it:

It makes me think I'm just plain posting to the wrong url, but that's the url I'm supposed to use.
