默认情况下，flash crossdomain中的“secure”属性设置为true，这意味着您不能从HTTP访问HTTPS上的内容。因此，您的swf应该从HTTPS连接到他们的API。

在我的例子中，问题是类似的，设置跨域策略也没有帮助我。所以我尝试请求API服务，而不是直接从SWF，而是通过我的网站上的php代理。它是这样的：

private static var agentURL:String = "https://myweb.com/agent.php";
private function sendRequest():void
{
  var service:HTTPService = new HTTPService();
  service.resultFormat = "e4x";
  service.useProxy = false;
  service.method = "POST";
  service.url = agentURL;
  var params:Object = new Object();
  params.myurl = "https://www.us8.api.mailchimp.com/2.0/lists/members.json?apikey=XXXXX&id=XXX";
  service.send(params);
}
/*some listeners for Result and Fault response */

下一个代码是针对文件 * agent.php * 的

<?php
set_time_limit(100);

$url = $_POST['myurl'];

try
{
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

    $result = curl_exec($curl);

    if (curl_errno($curl)) {
        print "CError: " . curl_error($curl); 
    } else { 
        print($result); 
        curl_close($curl); 
    }
}
catch(Exception $e)
{
    print '<message>' . $e->getMessage() . '</message>';
}
finally
{
    curl_close($curl);
}
?>
