【中文标题】即使使用实时 api 凭据,Paypal Express 结帐错误【英文标题】:Paypal Express Checkout Error even with live api credentials 【发布时间】:2015-03-07 07:48:03 【问题描述】:当我想在实时应用程序上执行 Express Checkout 方法时,我收到“错误:安全标头无效”。我已经使用有效的实时 API 凭据设置了 API 凭据,这是我从企业/商家帐户获得的。Api 端点也处于正确状态:https://api-3t.paypal.com/nvp。
我已经在沙盒上使用沙盒 API 凭据和 API 端点 (https://api-3t.sandbox.paypal.com/nvp) 对其进行了测试,它可以正常工作。
我真的不知道怎么了。
我是否需要创建 Paypal 应用程序来进行实时 API 调用?
下面是我使用 php curl 调用 API 的代码。

非常感谢您的宝贵时间。
【问题讨论】:
检查您的 Paypal API 用户名 - 您上面的内容看起来像是一个电子邮件地址,但它不应该是(当然,我只是根据您上面的内容)。 嗨@EdSF。我从我的企业帐户上的 API 签名生成器获取用户名凭据。它给了我这种用户名“intllabresearch_myapi1.gmail.com”,我该怎么办? 这实际上看起来是正确的(如果那是您的实际 api 用户名,请从这个 public 论坛中删除它)。 不,这不是实际的 api 用户名。我只是举个例子。 我不是 PHP 开发人员,所以..检查您传递给httpPost
的字符串 $ppdata
- 它可能只是格式错误。我认为您在setExpressCheckout
中发送了两次METHOD
(除非我的眼睛欺骗了我)。嗯……
【参考方案1】:
此错误表示您未使用正确的 API 凭据。
如果凭据正确,请查看您的端点。
沙盒凭据在生产环境中无效,实时凭据将在沙盒中产生此错误
【讨论】:
您好,我已经说过我没有在生产环境中使用沙箱凭据。您可以阅读我的声明。 错误码是10002。长消息是“Security header is not valid”。 抱歉坚持,请您逐字核对您的凭据。如您所见,这是唯一的可能性。 developer.paypal.com/docs/classic/api/errorcodes 注意:您的凭证上是否有 + 号,有人对此有疑问。 zen-cart.com/… 感谢您的关注@lea。我已经检查了两次和三次,我可以验证凭据没有“+”号。 不客气,很抱歉我能帮到你。 :(以上是关于即使使用实时 api 凭据,Paypal Express 结帐错误的主要内容,如果未能解决你的问题,请参考以下文章
带有 paypal ios sdk 的应用程序。沙盒和实时凭据?
