每件事情都正常,但我得到了失败的回应.如果我忘了什么,请帮助我.
提前致谢
如果您正在使用沙箱进行测试,请确保使用测试沙盒卖家帐户中的PDT令牌.
失败,4002或4003响应的原因
确保您回发"tx","cmd"和Auth值对于PayPal返回SUCCESS和交易详情,您的PDT脚本需要发布从返回字符串中提取的"tx"变量,来自您帐户的Auth令牌使用cmd"_notify-synch"到PayPal.
无效的身份验证令牌检查令牌以确保准确并正在正确传回.确保您的令牌是一个连续的字符串,并且脚本中没有换行符.对于某些语言,这可能会有所不同.
确保您没有回到错误的URL.如果您在Sandbox中进行测试,则需要确保将脚本发回www.sandbox.paypal.com.如果您在实际网站上,该脚本应回发到www.paypal.com.如果您在Sandbox中进行测试并且您的脚本发回现场网站(反之亦然),您将收到FAIL
验证相同的"tx"超过5次检查用户行为.获得失败的另一种方法是,如果你引用相同的"tx"超过5次.示例:如果用户在看到详细信息后刷新PDT页面5次,则他们将在上次刷新时看到FAIL.这不是错误.这是出于安全目的而完成的,因此无法无限期地访问PDT创建的URL以检索特定于事务的数据.
无效或缺少"tx"值"tx"值是用于收集付款信息的交易ID.如果此项无效或不存在,您将收到失败回复,因为无法检索付款数据.
PDT未收到
与付款关联的电子邮件地址要使PDT正常工作,您必须在按钮代码中确认用作业务价值的电子邮件地址.如果未确认此电子邮件地址,则PDT将无法工作,因为您将看不到附加到返回URL的PDT查询字符串.
确保使用格式正确的返回URL.启用PDT时,您用作默认自动返回URL的URL必须是有效的主机名或IP地址,而不是内部Intranet URL,否则用户将不会自动返回到该URL.确保使用有效的URL作为您希望用户返回的URL,否则您将看不到预期的结果.
订阅样式付款按钮PDT不适用于订阅,因为如果您有免费试用订阅,您将看不到返回页面/ PDT过程中的数据.这是因为PDT转移支付数据,如果在注册时,如果没有支付,则表示没有支付数据要转移.
用户行为PDT是通过返回方法激活客户,方法是选择返回按钮,或者在客户登录其PayPal帐户进行支付时不选择任何内容.这意味着买方可以更改退货流程或退出浏览器,并且不会传输任何数据.
