提供的 URI 方案“https”无效；调用 Web 服务时预期为“http”

Question

我正在尝试使用自定义 C# 代码从 CRM 工作流调用 SharePoint Web 服务。但是，当我运行代码时，出现以下错误：

The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via

这是有问题的代码：

#region Set up security binding and service endpoint
BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportCredentialOnly);
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.Ntlm;
EndpointAddress endpoint = new EndpointAddress(endpointAddress);
#endregion

#region Create the client and supply appropriate credentials
CopySPContents.CopyService.SharepointFileServiceClient client = new CopySPContents.CopyService.SharepointFileServiceClient(binding, endpoint);              
client.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
client.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;              
#endregion

#region Call the web service and trace its response
String response = client.CopyFolderContentsAcrossSites(sourceSiteURL, sourceFolderURL, destinationSiteURL, destinationFolderURL);
#endregion

在调用客户端方法的行String response = client.CopyFolderContentsAcrossSites(sourceSiteURL, sourceFolderURL, destinationSiteURL, destinationFolderURL); 上抛出错误。

感谢您的帮助，

根据 BasicHttpSecurityMode 的文档，TransportCredentialOnly 只能用于 HTTP。对于 HTTPS，您必须使用 Transport 或 TransportWithMessageCredential。
