我正在尝试通过“经典”NVP API 设置 PayPal Express Payment。

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。

我正在使用文档中的示例调用：

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"

外壳输出是：

* 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 执行此操作时，curl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机器和我可以访问的其他服务器发出请求（并取回正确的数据），所以我猜这是服务器端的一些错误配置。不是服务员，我有点不知所措。

cURL 已启用并记录以下内容phpinfo：

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。

A) 首先尝试wget https://api-3t.sandbox.paypal.com/nvp看看您是否可以通过“Bad Request”回复获得简单的连接，如果没有，您已被 Paypal 服务器阻止或您的防火墙阻止您在端口 443 上访问 paypal

B）尝试添加自定义标题：-H "Host: api-3t.sandbox.paypal.com"

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" -H "Host: api-3t.sandbox.paypal.com"

C) 你使用的是什么版本的 CURL 和在什么平台上？我有：

curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.21 Basic ECC zlib/1.2.3 libidn/1.18 libssh2/1.4.2

您的错误是由于您的服务器版本的 nss 包和 api-3t.sandbox.paypal.com 使用 SNI 证书。您可以通过执行来验证它

openssl s_client -servername api-3t.sandbox.paypal.com -tlsextdebug -connect api-3t.sandbox.paypal.com:443 2>/dev/null | grep "server name"

在 bash 上。输出TLS server extension "server name" (id=0), len=0表明此服务器具有 SNI 证书。

解决方案其实很简单。

对于 RedHat 变体：

sudo yum -y update nss*

对于 Debian 变体：

sudo apt-get update nss*

您实际上不必更改代码（对于连接方面的问题）

很可能由于身份验证错误或颁发的 ssl 证书无效，PayPal Express Payment 服务停止/切断您的连接。在这种情况下，请尝试向服务提供商询问此问题。

希望能解决您的问题。

就我而言，我现在已经在我的服务器中启用了 ICMP 流量，并且可以正常工作。

iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT
iptables -F INPUT; iptables -F OUTPUT
