Question

我在服务器上的IIS中托管了一个Web应用程序，该服务器与安装在同一服务器上的Web服务进行通信。 Web Service作为标准服务安装，而不是通过IIS安装。

该服务已启动并正在运行，我可以使用https在浏览器中导航到该服务。我使用netsh添加了证书： WCF with transport security via certificates

但是，当Web应用程序尝试调用对Web服务的调用时，我会收到以下错误：

An error occurred while making the HTTP request to https://TheServer/VehicleService/ConnectXml/1.0/https. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.

我深入研究了这个错误，我发现了这个：

<ExceptionType>System.IO.IOException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType>
<Message>Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.</Message>
<ExceptionType>System.Net.WebException, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType>
 <Message>The underlying connection was closed: An unexpected error occurred on a send.</Message>

有谁知道导致这个问题的原因是什么？我是否需要向IIS添加任何额外配置？

我尝试过在本地添加证书，但它对我来说很好。

您的SecurityProtocolType可能未启用（来自Windows注册表）。如果你也得到这个：

System.IO.IOException: Unable to read data from the transport connection

尝试以下协议类型之一：

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;   // Tls, Tls11, or Tls12

WCF传输与https通信与证书问题
