在Paypal中检查验证邮件

$url = trim("https://svcs.sandbox.paypal.com/AdaptiveAccounts/GetVerifiedStatus"); //Sandbox URL
$API_UserName = "XXXXXXX";
$API_Password = "XXXXXXX";
$API_Signature ="XXXXXXX";
$API_AppID = "APP-80W284485P519543T";
$API_RequestFormat = "NV";
$API_ResponseFormat = "NV";
$bodyparams = array ("requestEnvelope.errorLanguage" => "en_US",
                     "emailAddress" =>"xxxx@gmail.com",
                     "firstName" =>"XXX",
                     "lastName" =>"YYY",
                     "matchCriteria" => "NAME"
                    );
$body_data = http_build_query($bodyparams, "", chr(38));

我正在做上面的代码，但它没有给我任何输出。谁能告诉我我哪里错了?

如果我使用以下URL

$url = trim("https://svcs.paypal.com/AdaptiveAccounts/GetVerifiedStatus"); //Paypal URL

然后它给我以下响应
