PayPal API CreateRecurringPaymentsProfile拒绝工作

过去5个小时我一直在搜索有关此事的信息,并且发现了很多不起作用的信息。我已成功使用setExpressCheckout API,获取详细信息并收取正常订单,但是当我想创建定期付款配置文件时,我总是会收到无效的令牌错误。我知道这不是一个无效的令牌,但我不知道该怎么做。

我目前正在使用PayPal的setExpressCheckout和createRecurringPaymentsProfile示例代码,但没有成功。

这是来自PayPal的我可笑的简化代码。

<?

$environment = 'sandbox';   // or 'beta-sandbox' or 'live'
$ROOT_URL = 'http://example.com/paypal/';

/**
 * Send HTTP POST Request
 *
 * @param   string  The API method name
 * @param   string  The POST Message fields in &name=value pair format
 * @return  array   Parsed HTTP Response body
 */
function PPHttpPost($methodName_, $nvpStr_) {

    global $environment;

    $API_UserName = urlencode('email');
    $API_Password = urlencode('pass');
    $API_Signature = urlencode('sig');
    $API_Endpoint = "https://api-3t.paypal.com/nvp";
    if("sandbox" === $environment || "beta-sandbox" === $environment) {
        $API_Endpoint = "https://api-3t.$environment.paypal.com/nvp";
    }
    $version = urlencode('51.0');

    // setting the curl parameters.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $API_Endpoint);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);

    // turning off the server and peer verification(TrustManager Concept).
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);

    // NVPRequest for submitting to server
    $nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$API_Password&USER=$API_UserName&SIGNATURE=$API_Signature$nvpStr_";

    // setting the nvpreq as POST FIELD to curl
    curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);

    // getting response from server
    $httpResponse = curl_exec($ch);

    if(!$httpResponse) {
        exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');
    }

    // Extract the RefundTransaction response details
    $httpResponseAr = explode("&", $httpResponse);

    $httpParsedResponseAr = array();
    foreach ($httpResponseAr as $i => $value) {
        $tmpAr = explode("=", $value);
        if(sizeof($tmpAr) > 1) {
            $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
        }
    }

    if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {
        exit("Invalid HTTP Response for POST request($nvpreq) to $API_Endpoint.");
    }

    return $httpParsedResponseAr;
}


 $paymentAmount = urlencode(34.00);
if(!isset($_REQUEST['token'])){  
     // Set request-specific fields.

    $currencyID = urlencode('USD');                         // or other currency code ('GBP', 'EUR', 'JPY', 'CAD', 'AUD')
    $paymentType = urlencode('Authorization');              // or 'Sale' or 'Order'

    $returnURL = urlencode($ROOT_URL.'/buy.php?return=1');
    $cancelURL = urlencode($ROOT_URL.'/buy.php?cancel=1');

    // Add request-specific fields to the request string.
    $nvpStr = "&Amt=$paymentAmount&ReturnUrl=$returnURL&CANCELURL=$cancelURL&PAYMENTACTION=$paymentType&CURRENCYCODE=$currencyID";

    // Execute the API operation; see the PPHttpPost function above.
    $httpParsedResponseAr = PPHttpPost('SetExpressCheckout', $nvpStr);

    print_r($httpParsedResponseAr);

    if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) {
        // Redirect to paypal.com.
        $token = urldecode($httpParsedResponseAr["TOKEN"]);
        $payPalURL = "https://www.paypal.com/webscr&cmd=_express-checkout&token=$token";
        if("sandbox" === $environment || "beta-sandbox" === $environment) {
            $payPalURL = "https://www.$environment.paypal.com/webscr&cmd=_express-checkout&token=$token";
        }

        //header("Location: $payPalURL");
        echo '<a href="'.$payPalURL.'">PayPal</a>';
        exit;
    } else  {
        exit('SetExpressCheckout failed: ' . print_r($httpParsedResponseAr, true));
    }
}else{
    $token = urlencode($_REQUEST['token']);
    //Now create recurring profile
    ?>
    <h1>Yes!</h1>
    <?


$currencyID = urlencode("USD");                     // or other currency code ('GBP', 'EUR', 'JPY', 'CAD', 'AUD')
$startDate = urlencode("2012-9-6T0:0:0");
$billingPeriod = urlencode("Month");                // or "Day", "Week", "SemiMonth", "Year"
$billingFreq = urlencode("4");                      // combination of this and billingPeriod must be at most a year

$nvpStr="&TOKEN=$token&AMT=$paymentAmount&CURRENCYCODE=$currencyID&PROFILESTARTDATE=$startDate";
$nvpStr .= "&BILLINGPERIOD=$billingPeriod&BILLINGFREQUENCY=$billingFreq";

$httpParsedResponseAr = PPHttpPost('CreateRecurringPaymentsProfile', $nvpStr);

if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) {
    exit('CreateRecurringPaymentsProfile Completed Successfully: '.print_r($httpParsedResponseAr, true));
} else  {
    exit('CreateRecurringPaymentsProfile failed: ' . print_r($httpParsedResponseAr, true));
}
}
?>

显然,这里的电子邮件,通行证和签名都是错误的。我的脚本名称是example.com/paypal/buy.php如果不清楚的话......

更新:我终于找到了有用的东西。我还没有漂亮的代码,但它确实至少经历过。 https://www.x.com/developers/paypal/forums/nvp/createrecurringpaymentsprofile-invalid-token-0

答案 0 :(得分:6)

你知道这一切吗?如果您未在SetExpressCheckout请求中包含结算协议(定期付款)信息,则会出现无效令牌错误的原因。

这是一个sample set,当这个问题出现时,我总是用它来向人们展示。请注意SEC中包含的BILLINGTYPE和BILLINGAGREEMENTDESCRIPTION。
