php - 无法通过 cURL 连接到 PayPal API

Question

我正在尝试通过“经典”NVP API 设置 PayPal 快速支付。

尝试使用 cURL 从我的服务器连接到 PayPal-Sandbox，连接停止并在大约 2 分钟后超时。

我正在使用 example call来自文档:

curl -v --insecure  https://api-3t.sandbox.paypal.com/nvp  -d  "USER=platfo_1255077030_biz_api1.gmail.com&PWD=1255077037&SIGNATURE=Abg0gYcQyxQvnf2HDJkKtA-p6pqhA1k-KTYE0Gcy1diujFio4io5Vqjf&METHOD=SetExpressCheckout&VERSION=78&PAYMENTREQUEST_0_PAYMENTACTION=SALE&PAYMENTREQUEST_0_AMT=19&PAYMENTREQUEST_0_CURRENCYCODE=USD&cancelUrl=http://www.yourdomain.com/cancel.html&returnUrl=http://www.yourdomain.com/success.html"

外壳输出为:

* About to connect() to api-3t.sandbox.paypal.com port 443 (#0)
* Trying 173.0.82.83... Connection timed out
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host

当我尝试通过 PHP curl 执行此操作时，我没有收到任何错误，只是一个空的资源句柄。

我可以轻松地从我的本地计算机和我可以访问的其他服务器执行请求(并获取正确的数据)，所以我猜这是一些服务器端配置错误。不是服务器人员，我有点无能为力。

cURL 已启用并在 phpinfo 中记录以下内容:

libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

openSSL 也已启用。此外，我在尝试连接到 API 的实时版本时遇到了同样的问题。
