Paypal自适应支付ipn错误

Question

我的PHP paypal自适应支付IPN网址遇到错误，我已将其缩小到这个范围：

Paypal返回

Array
(
[Errors] => Array
    (
        [0] => Array
            (
                [Receiver] => 
                [Category] => Application
                [Domain] => PLATFORM
                [ErrorID] => 580001
                [ExceptionID] => 
                [Message] => Invalid request: {0}
                [Parameter] => 
                [Severity] => Error
                [Subdomain] => Application
            )

    )

)

我把它缩小到我的IPN网址及其GET数据。

http://myurl.com/?uid=123&pid=2

如果我执行单个变量，则会创建Paypal，因此似乎添加＆amp;标志打破它。我取代了＆amp;用一个+并且它创建了请求，我还手动提供了ipn_url设置数据，所以它与缺少变量php方面无关。所以我很困惑该怎么做。
