php – 将PayPal返回URL设置为localhost

我正在尝试集成Paypal,我正在使用沙盒.我按照下面问题中接受的答案的步骤. Setting PayPal return URL and making it auto return?

但是当我尝试输入URL时,Paypal会返回以下错误.

We were unable to validate the URL you have entered. Please check your entry and try again.

我试图设置的URL是http：// localhost：8888 / paypal / success.php.

此外,我尝试使用下面的表单发送返回URL.

<input type="hidden" name="return" value="http://localhost:8888/paypal/success.php">

这两种方法对我都不起作用.

完整形式

<form method="post" action="https://www.sandbox.paypal.com/cgi-bin/webscr">
<!-- Identify your business so that you can collect the payments. -->
<input type="hidden" value="[e-mail]" name="business">
<!-- Specify a Buy Now button. -->
<input type="hidden" value="_xclick" name="cmd">
<!-- Specify details about the item that buyers will purchase. -->
<input type="hidden" value="AM Test Item" name="item_name">
<input type="hidden" value="22.16" name="amount">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" value="item_number" name="item_number">
<input type="hidden" name="return" value="http://localhost:8888/paypal/success.php">
<!-- Display the payment button. -->
<input type="image" name="submit" border="0" src="https://www.paypalobjects.com/en_US/i/btn/btn_buynow_LG.gif" alt="PayPal - The safer,easier way to pay online">

</form>

如何在我的开发电脑上测试？

如果您尝试指定IP地址而不是localhost,该怎么办？

无法在远程计算机上解析本地主机.它只是您知道localhost语句的本地DNS,并且是127.0.0.1.
