从 powershell 连接到 WCF Rest 服务应用程序未按预期工作

Question

我设置了一个 WCF 服务应用程序，因此当我调用该地址时，它只返回 true。

远程服务.cs

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

远程服务.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 url 访问该服务：

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

这返回：

{"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，我尝试过一个名为“我只是在休息”的客户端应用程序，它返回了预期的内容。 所以我认为这一定与powershell有关。 我没有允许 web.config 文件中的某些内容或 powershell 中缺少某些设置。 我还尝试忽略 powershell 上的证书错误。 这没有帮助。

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
+           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

这是服务的 web.config 文件：

设法找到了问题。

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

我会删除这个问题，但也许这可能会在将来对某人有所帮助:)
