好的,所以下面的代码给了我上面的错误“开始日期无效”。即使我从各种来源验证它是一个有效且格式正确的开始日期。代码的 res 没有问题,因为它成功返回了正确的余额。我已经搜索了所有地方,但找不到解决方案。请帮忙。谢谢!

class Paypal

print_r($paypal->call('TransactionSearch', array("STARTDATE"=>"2016-02-24T00:00:00Z")));

【问题讨论】:

正确的样本应该是:STARTDATE = 2016-05-25T00:00:00Z。参考developer.paypal.com/docs/classic/api/merchant/… 【参考方案1】:

我认为您对$this->encodeFields()(在call() 内部)的调用导致您的参数值变为双倍urlencode()'d。 $this->encodeFields()$fields 数组中的每个元素上调用 urlencode();但是,http_build_query() 会自动为您执行此操作。因此,您在调用 PayPal 时可能以 STARTDATE=2016-02-24T00%253A00%253A00Z 结尾,而实际上它应该是 STARTDATE=2016-02-24T00%3A00%3A00Z

【讨论】:

这是有道理的。会试一试
