推荐答案

我看不到成功消息尝试在curl请求之后输出任何内容，唯一让我感到震惊的事情 - 以及其他人可能完全不同意 - 是在选项中没有什么可以专门处理https通信，在我的经验中，需要设置其他选项。我以前没有处理过PayPal API，所以这可能没有什么用处，但.....

I can see no "success message" - nor any attempt to output anything after the curl request, the only thing that struck me - and others may well disagree - is that there is nothing in the options to specifically deal with https communications which, in my experience, require other options to be set. I've not dealt with the PayPal api before so this might provide nothing of use, but.....

请尝试下载 cacert.pem - google是您的朋友。

try downloading a copy of cacert.pem - google is your friend.

<?php
    $tx = $_GET['tx'];
    $ID = $_GET['cm'];
    $currency = $_GET['cc'];
    $identity = '0iMIW7w4OXAed9Tvz6l9fpUY8B-E_WtE3toU7sT5gIzDJc9uPUgt9sVCN30';

    /* Use the full path to your own cacert.pem, download from the interwebs if you do not have a copy */
    $cacert = 'c:/wwwroot/cacert.pem'; 

    $url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
    $fields = array(    
        'cmd'   => '_notify-synch',
        'tx'    => $tx,
        'at'    => $identity,
    );

    $request = curl_init();
    curl_setopt($request,CURLOPT_URL, $url);

    if( parse_url( $url,PHP_URL_SCHEME )=='https' ){
        curl_setopt( $request, CURLOPT_SSL_VERIFYPEER, FALSE ); /* set to true once you get this working */
        curl_setopt( $request, CURLOPT_SSL_VERIFYHOST, 2 );
        curl_setopt( $request, CURLOPT_CAINFO, realpath( $cacert ) );
    }


    /* this should be true or false not count($fields): in this case true*/
    /*curl_setopt($request,CURLOPT_POST, count( $fields ) );*/
    curl_setopt($request,CURLOPT_POST, true );
    curl_setopt($request,CURLOPT_POSTFIELDS, http_build_query( $fields ) );
    curl_setopt($request,CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($request,CURLOPT_HEADER, FALSE);

    /* Quite often requests get rejected for no useragent */
    curl_setopt($request,CURLOPT_USERAGENT, 'paypal-mozilla-chrome-useragent' );
    curl_setopt($request, CURLINFO_HEADER_OUT, TRUE );


    $response = curl_exec($request);
    $status   = curl_getinfo($request, CURLINFO_HTTP_CODE);

    curl_close($request);
    /* See what the curl request has retrieved */
    echo '<pre>',print_r( $response, true ),$status,'</pre>';
?>
