Paypal付款数据传输无法在沙箱中运行(Paypal Payment Data Transfer not working in sandbox)

我试图让Paypal在交易后重定向到我的网站并检索有关交易的信息。 到目前为止,Paypal确实重定向到了正确的位置,但之后我回到Paypal的php curl操作检索了一个错误页面而不是我期望的SUCCESS / FAIL消息:

对不起 - 您的上一个操作无法完成

[...]

我们目前无法完成您的请求。 请单击“重试”或稍后重试。 我们对不便表示抱歉。

消息3004

我试过让我的代码在屏幕上打印'tx'参数,手动构建我的请求并将其直接放在浏览器中,即:

https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_notify-synch&tx=34A96012RS258972T&at=x7cYS4yOvBi2k_LuLWsJ3h_J-2n-29VCgzhFDR79on8s1mQSlSxIIibiW3e

但是返回上面描述的相同错误页面。

我已登录到我的沙盒paypal帐户,'at'参数包含与我的沙盒商家测试帐户关联的正确的付款数据传输身份令牌。

我的请求缺少什么吗? 我没有用我的实际Paypal帐户测试它,因为我不想要任何真正的货币兑换,直到我知道它有效。


I'm trying to get Paypal to redirect to my website after a transaction and retrieve information about the transaction. So far, Paypal does redirect to the correct location, but the php curl operation that I make back to Paypal afterwards retrieves an error page instead of the SUCCESS/FAIL message I'm expecting:

Sorry — your last action could not be completed

[...]

We are unable to complete your request at this time. Please click Retry or try again later. We apologize for the inconvenience.

Message 3004

I've tried simply having my code print the 'tx' parameter on screen, building my request manually and putting it directly in the browser, ie:

https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_notify-synch&tx=34A96012RS258972T&at=x7cYS4yOvBi2k_LuLWsJ3h_J-2n-29VCgzhFDR79on8s1mQSlSxIIibiW3e

But the same error page described above gets returned.

I'm logged in to my sandbox paypal account, and the 'at' parameter holds the correct payment data transfer identity token associated with my sandbox merchant test account.

Is my request missing anything? I haven't tested it with my actual Paypal account since I don't want any real money exchanges until I know it works.

最满意答案

正如评论中所提到的,最简单的方法是始终返回Promise,并使用已完成的Promise包装非异步操作。 要将值包装在已完成的promise中,只需使用static pure方法:

public static Promise<Result> doSomethingAsync() {
  if (...) {
    return getData();
  } else {
    return F.Promise.pure(ok(...));
  }
}

As mentioned in the comment, the easiest would be to always return a Promise, and wrap non-async actions with a completed Promise. To wrap a value in a completed promise, simply use the static pure method:

public static Promise<Result> doSomethingAsync() {
  if (...) {
    return getData();
  } else {
    return F.Promise.pure(ok(...));
  }
}
