我正在尝试使用 curl 向 2 个用户模拟虚拟并行支付。我已经按照文档做了所有事情，但问题是我得到了
获取 L_ERRORCODE0=10001& 超时处理请求
我不知道为什么。
我的代码如下：
<?php
$data = array(
'USER'=>urlencode('xxx'),
'PWD'=>urlencode('xxxx'),
'SIGNATURE'=>urlencode('xxxx'),
'VERSION'=>urlencode('86.0'),
'METHOD'=>urlencode('SetExpressCheckout'),
'RETURNURL'=>urlencode('http://75.125.190.162:7132/sample/php_nvp_samples/myCheckout.php'),
'CANCELURL'=>urlencode('http://75.125.190.162:7132/sample/php_nvp_samples/myCheckout.php'),
'PAYMENTREQUEST_0_CURRENCYCODE'=>urlencode('USD'),
'PAYMENTREQUEST_0_AMT'=>urlencode('300'),
'PAYMENTREQUEST_0_ITEMAMT'=>urlencode('200'),
'PAYMENTREQUEST_0_TAXAMT'=>urlencode('100'),
'PAYMENTREQUEST_0_DESC'=>urlencode('Summer Vacation trip'),
'PAYMENTREQUEST_0_SELLERPAYPALACCOUNTID'=>urlencode('himans_1331094418_biz@smartdatainc.net'),
'PAYMENTREQUEST_0_PAYMENTACTION'=>urlencode('Order'),
'PAYMENTREQUEST_0_PAYMENTREQUESTID'=>urlencode('CART26488-PAYMENT0'),
'PAYMENTREQUEST_1_CURRENCYCODE'=>urlencode('USD'),
'PAYMENTREQUEST_1_AMT'=>urlencode('100'),
'PAYMENTREQUEST_1_ITEMAMT'=>urlencode('50'),
'PAYMENTREQUEST_1_TAXAMT'=>urlencode('50'),
'PAYMENTREQUEST_1_DESC'=>urlencode('Dancing class'),
'PAYMENTREQUEST_1_SELLERPAYPALACCOUNTID'=>urlencode('himans_1320303266_biz@smartdatainc.net'),
'PAYMENTREQUEST_1_PAYMENTACTION'=>urlencode('Order'),
'PAYMENTREQUEST_1_PAYMENTREQUESTID'=>urlencode('CART26485-PAYMENT0')
);
$curl = curl_init('https://api-3t.sandbox.paypal.com/nvp');
curl_setopt($curl,CURLOPT_RETURNTRANSFER ,1);
curl_setopt($curl,CURLOPT_HTTPGET ,true);
curl_setopt($curl,CURLOPT_POSTFIELDS ,$data);
$response = curl_exec($curl);
echo $response;
exit;
curl_close($curl);
?>
这是请求的vardump：
array(15) {
["USER"]=> string(43) "XXX"
["PWD"]=> string(10) "XXX"
["SIGNATURE"]=> string(56) "XXX"
["VERSION"]=> string(4) "56.0"
["METHOD"]=> string(18) "SetExpressCheckout"
["RETURNURL"]=> string(78)
"http%3A%2F%2F75.125.190.162%3A7132%2Fsample%2Fphp_nvp_samples%2FmyCheckout.php"
["CANCELURL"]=> string(78)
"http%3A%2F%2F75.125.190.162%3A7132%2Fsample%2Fphp_nvp_samples%2FmyCheckout.php"
["PAYMENTREQUEST_0_CURRENCYCODE"]=> string(3) "USD"
["PAYMENTREQUEST_0_AMT"]=> string(3) "100"
["PAYMENTREQUEST_0_ITEMAMT"]=> string(2) "50"
["PAYMENTREQUEST_0_TAXAMT"]=> string(2) "20"
["PAYMENTREQUEST_0_DESC"]=> string(13) "Dancing class"

["PAYMENTREQUEST_0_PAYMENTACTION"]=> string(5) "Order"
