Question

我设置了一个WCF服务应用程序，所以当我调用该地址时，它只返回true。

IRemoteService.cs

     [OperationContract]
            [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json,
               BodyStyle = WebMessageBodyStyle.Wrapped,
               UriTemplate = "ValidationResult/")]
            bool ValidationResult();

RemoteService.svc.cs

namespace RemoteService
{    
    public class RemoteService : IRemoteService
    {
        public bool ValidationResult()
        {
            return true;
            //throw new NotImplementedException();
        }
    }
}

我在IIS上添加了一个应用程序，现在我可以通过以下网址访问该服务：

https://localhost/ValidationServiceApp/RemoteService.svc/validationresult/

返回：

{"ValidationResultResult":true}

效果很好。但是，当我运行以下powershell脚本时，我无法访问该服务：

$url = "https://localhost/ValidationServiceApp/SASRemoteService.svc/validationresult/"
$result = Invoke-RestMethod -Method GET -Uri $url 
Write-Host $result

我必须指出，我已经尝试过一个名为“我只是休息”的客户端应用程序。这会返回预期的结果。所以我认为它必须与powershell有关。要么我还没有在web.config文件中允许某些内容，要么在PowerShell中缺少某些设置。我还试图忽略powershell上的证书错误。这没有任何帮助。

来自powershell的错误：

Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a send.
At line:18 char:11
+ $result = Invoke-RestMethod -Method GET -Uri $url
+           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

以下是该服务的web.config文件：

管理以找到问题。

我需要在IIS中编辑托管服务的权限。所以我将用户({pcname}/Users)添加到允许用户列表中。

我会删除这个问题，但也许这可能有助于未来的人：）

从powershell连接到WCF Rest Service应用程序不能按预期工作
