这是我第一次使用PayPal API,所以请耐心等待。
我正在尝试使用BMCreateButton API动态创建加密按钮,使用了稍微修改过的代码来自这个页面。不幸的是,我似乎无法让它工作,因为在PHP错误日志中出现了“身份验证/授权失败”的消息。(我也在PayPal开发者论坛上提出了这个问题,但没有得到答案。)
这段代码:
function createButton($name, $price) {
// Check to make sure that our version of PHP supports SOAP.
if((PHP_VERSION_ID < 50101) || !in_array("soap", get_loaded_extensions())) {
error_log("PHP not running with SOAP");
} else {
include_once("config.php"); //this file holds the credentials and whether it's running in sandbox mode or not
//basic variable validation
$price = floatval($price);
// Import the PayPal WSDL.
$location = $sandbox ? "https://api-3t.sandbox.paypal.com/2.0/" : "https://api-3t.paypal.com/2.0/";
$soapClient = new SoapClient("https://www.paypalobjects.com/wsdl/PayPalSvc.wsdl", array(
location => $location
));
// Set our API credentials.
$credentials->Credentials->Username = $username;
$credentials->Credentials->Password = $password;
$credentials->Credentials->Signature = $signature;
$soapClient->__setSoapHeaders(new SoapHeader("urn:ebay:api:PayPalAPI", "RequesterCredentials", $credentials));
// Start creating our BMCreateButtonReq object. For full details about this object, see
// http://tinyurl.com/3mxau6j .
$BMCreateButtonReq->BMCreateButtonRequest->Version = "71.0";
$BMCreateButtonReq->BMCreateButtonRequest->ButtonCode = "ENCRYPTED";
// What type of button are we creating?
$BMCreateButtonReq->BMCreateButtonRequest->ButtonType = "CART";
// Specific variables for this button. For the full list of options, see
// http://tinyurl.com/6qyanl . For a basic payment, these two should be enough.
$BMCreateButtonReq->BMCreateButtonRequest->ButtonVar[] = "amount=$price";
$BMCreateButtonReq->BMCreateButtonRequest->ButtonVar[] = "item_name=$name";
// Run the API call.
$response = $soapClient->BMCreateButton($BMCreateButtonReq);
if($response->Ack == "Success" || $response->Ack == "SuccessWithWarning") {
// If successful, the button code will be in the Website element of $response.
// It'll be a full HTML form, so don't wrap it in any <form> tags -- just
// display it as-is.
echo $response->Website;
} else {
error_log("Could not create PayPal button. " . serialize($response->Errors));
echo "<p class=\"note\">Cannot create button</p>";
}
}
}
在错误日志中会显示如下内容:
Could not create PayPal button. O:8:"stdClass":4:{s:12:"ShortMessage";s:35:"Authentication/Authorization Failed";s:11:"LongMessage";s:49:"You do not have permissions to make this API call";s:9:"ErrorCode";s:5:"10002";s:12:"SeverityCode";s:5:"Error";}
我已经检查过凭据,它们是正确的,但在沙箱和生产环境API中都失败了。我是否遗漏了某些基本知识,或者可能忽略了代码中的错误?请帮我看下。
