问题描述
当我创建贝宝付款协议时，它会返回带令牌的REDIRECT链接.
When I create an agreement for paypal payment, it return the REDIRECT link with a token.
用户必须通过此链接连接到Paypal并接受协议，然后我才能执行协议.
The user must connect to paypal via this link and accept agreement, then I can execute agreement.
我想知道REDIRECT链接(及其关联的令牌)有效期是多长时间?我问是因为我想要最高的预先计算协议并将其放在缓存中，所以如果用户要订阅，我会使用缓存的REDIRECT链接，而且速度很快.创建协议呼叫需要2秒钟的时间，太长了，在结帐阶段，速度至关重要.
I want to know, how long the REDIRECT link (and its assoicated token) is valid ? I ask because I want top precompute agreement and put them in cache, so If user want to subscribe I use a cached REDIRECT link and it's fast. Create agreement call take 2 seconds, it's too long, speed is critical at checkout stage.
我使用REST API + Java.
I use the REST API + Java.
推荐答案
Express Checkout令牌(这是REST API为Billing Agreement调用返回的内容)在3小时后失效.
Express Checkout tokens (which is what REST API returns for the Billing Agreement calls) expire after 3 hours.
