【问题描述】：
目前正在制作一个Android应用，并决定在其中集成Paypal支付，以便将用户重定向到应用内的Paypal支付。
我找到了我想做的 Paypal SampleApp： https://github.com/paypal/PayPal-Android-SDK。 首先，我对其进行了测试，它在 CONFIG_ENVIRONMENT 设置为 PayPalConfiguration.ENVIRONMENT_NO_NETWORK 和默认沙箱示例 acc（usr: sample@buy.com, pass:123123123）下正常工作。
然后我在 developer.paypal.com 上创建了一个帐户，以便向我的 Paypal 帐户付款（CONFIG_ENVIRONMENT 设置为 PayPalConfiguration.ENVIRONMENT_PRODUCTION）。我创建了一个应用程序，并使用了 SampleApp 中开发人员门户提供的客户端 ID。这样做，支付没有完成，并给出错误：
request failure with http statusCode:400,exception:Bad Request
request failed with server response:{"name":"DUPLICATE_REQUEST_ID","debug_id":"9f83f9a8ce3e5","message":"The value of PayPal-Request-Id header has already been used","information_link":"https://developer.paypal.com/webapps/developer/docs/api/","details":[]}
DUPLICATE_REQUEST_ID
注意：我只在示例应用程序中使用“购买东西”选项；对其他选项不感兴趣
