SOAP WebService调用错误：基础连接已关闭：服务器已关闭预期保持活动状态的连接。 [英] SOAP WebService Call error: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server..
问题描述
基础连接已关闭：A服务器关闭了预期保持活动状态的连接..
我们正在尝试使用他们的网络服务将一些xml数据导出到客户端服务器，但我们收到以下异常
在某些情况下连接花费的时间超过预期时间。
"The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.."
请让我如何解决此问题。当我连接到此服务器时，我有以下代码
ItfResidentTransactions2_0 paymentExport = new ItfResidentTransactions2_0（）;
< span style ="font-size：11pt; font-family：" Calibri"，" sans-serif""> ServicePointManager.CertificatePolicy = new Common.TrustAllCertificatePolicy（）;
paymentExport.Url = integrationDtls.ClientWSURL; // wsURL;
paymentExport.Timeout = System.Threading.Timeout.Infinite;
推荐答案
（1）您的PC（运行在其上的客户端应用程序）是否位于代理服务器/防火墙之后。尝试通过"打开"连接消费服务。
（2） ）服务是否期望从您这边进行任何类型的身份验证..？
（3）您是否公开了数量巨大的数据。可能是请求超时的原因。
(1) Is your PC, the client app running on which, is behind proxy server/firewall. Try consuming service over an "open" connection.
(2) Is the service expecting any kind of authentication from your side..?
(3) Are you exposrting the data which is huge in size. Possible reason that the request is timing out.
