本文介绍了如何从本地SharePoint 2013和ADFS中获取FedAuth Cookie的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个使用Windows Server 2012 R2，ADFS和sharepoint 2013设置的测试环境。我可以使用ADFS作为Claims Identity提供程序成功登录到Sharepoint 2013。现在，我试图从我的C＃应用程序登录到Sharepoint。
我可以使用以下命令从adfs请求saml断言令牌。
现在，我需要将saml令牌发布到SharePoint并检索FedAuth cookie的帮助，以便我可以被动地登录到SharePoint 2013并从C＃应用程序上载文档。 / p>
当我调用最后一个方法PostSharePointSTS（）时，未设置Cookie。
大多数代码是
[TestMethod]

client.Headers.Add（ Content-Type， application / soap + xml; charset = utf-8）;

解决方案
为什么不使用标准SharePoint CSOM库在SharePoint中做什么？ CSOM会自动在SharePoint端代表用户执行所有必需的ADFS交互。
I have a test environment set up using windows server 2012 R2, ADFS and sharepoint 2013. I can successfully login to Sharepoint 2013 using ADFS as the Claims Identity provider. Now I am trying to login to Sharepoint from my C# application.
I am able to request the saml assertion token from adfs using the following.
Now i would like help with posting the saml token to SharePoint and retrieve a FedAuth cookie so I can passively login to SharePoint 2013 and upload a document from a C# application.
When I call the last method PostSharePointSTS() No Cookies are set.
most of the code has been the help of Leandro Boffi

Why don't you just use the standard SharePoint CSOM library to do whatever you want in SharePoint? CSOM does all the necessary ADFS interaction on behalf of the user on the SharePoint side automatically.
