c# - 无法解析远程名称 : 'sandbox.api.mastercard.com'

Question

我正在尝试通过 MoneySend api 在万事达卡的沙盒上发出付款请求。这是示例代码，也可以在 here for c# 中找到

问题陈述:

当我尝试直接通过 visual studio 发出请求时，它工作得很好，但是当我在 IIS 上部署此服务时，它显示错误

The remote name could not be resolved: 'sandbox.api.mastercard.com'

进一步说明:

在 VS 2017 中创建了解决方案，在其中创建了 2 个项目，其中一项服务和其他用于在控制台中测试相同服务的服务。通过在控制台中指向服务的服务引用，它工作正常。当我在 IIS 上部署服务并将服务端点从本地 VS 链接替换为控制台应用程序中部署的 IIS 链接时，出现上述错误。

更新:

我在一家互联网服务有自己的 DNS 和代理设置的公司工作。

完全异常:

通过在服务项目的web.config中添加代理解决

<system.net>
    <defaultProxy useDefaultCredentials="false">
      <proxy
        proxyaddress="http://myurladdress:myport"
        bypassonlocal="True"
        usesystemdefault="False"
      />
    </defaultProxy>
</system.net>
