使用SharePoint中的当前用户凭据调用Web服务 [英] Calling web service with current users credentials from SharePoint

问题描述

当我从我的vs2010客户端运行这个C＃代码时，它可以像我一样进行身份验证。

When I run this C# code from my vs2010 client it works authenticating as me.

但是，如果我将代码部署到网络服务器上的sharePoint页面，我会得到一个来自Web服务的身份验证错误。

However if I deploy the code to a sharePoint page on a webserver I get an authentication error from the web service.

我理解这个双跳问题，我需要冒充。也许代码是以SharePoint服务用户的身份调用Web服务。

I understand this some double hop issue and I need to impersonate. maybe the code is calling the web service as the SharePoint service user.

除硬编码凭证之外还有什么简单的方法吗？

Any easy way around this beyond hard coding credentials?

Uri uri = new Uri("http://tempuri.org/"); 
ICredentials credentials = CredentialCache.DefaultCredentials; 
NetworkCredential credential = credentials.GetCredential(uri, "Basic"); 
Service service = new Service("https://xxx/Exchange.asmx", credential);

有人建议使用带有模仿的windowsidentity类，但不知道如何将其插入。

Someone suggested using windowsidentity class with impersonate, but not sure how to plug that in.

谢谢。

推荐答案

如果您信任使用应用程序池标识进行交互使用您的远程Web服务，您可以使用此技术：

If you are trusted to use the application pool identity to interact with your remote web service then you can use this technique:
