我已经安装了 paypal api 证书并使用 winhttpcertcfg 授予私钥访问正确身份的权限。我已经用尽了在各种论坛上找到的所有“已知修复程序”，但仍然出现此错误。我正在运行最新的 msxml 版本。

使用 Paypal 代码示例我得到错误

msxml3.dll error '80072f0c' A certificate is required to complete client authentication

无论是使用 MSXML2.ServerXMLHTTP 的 3.0、4.0 还是 6.0 版本，错误都是不变的，并且在尝试使用 REST Api 时收到相同的错误。

我正在测试连接的代码如下。

请您参考如下方法:

证书身份验证在经典 ASP 中不起作用。尝试使用外部库(如 cURL)来执行 HTTPS 请求。
